Resolution 4k

The Sony X900H, also sold as the X90CH at Costco, is a great 4k TV for nearly any type of content. It has a VA panel with an excellent contrast ratio and a full-array local dimming feature that makes blacks look even better in the dark. It's well-suited for bright rooms, as it has decent reflection handling and gets bright enough to easily overcome glare. It displays fast-moving scenes with minimal blur thanks to its quick response time and optional Black Frame Insertion feature. Gamers should be happy with its low input lag, which remains low even when playing in 4k with 10-bit HDR. It has variable refresh rate (VRR) support once you update it to its latest firmware, but input lag is a bit high in it. Sadly, its viewing angles are narrow, so images look washed out when viewed from the side.

Our Verdict

8.1 Mixed Usage

The Sony X900H is a great TV for mixed usage. Its picture quality is great thanks to its excellent contrast ratio, high peak brightness, and wide color gamut. HDR content also looks good, with rich colors and highlights that pop for the most part. Gamers should appreciate its fast response time, low input lag, and VRR support after a firmware update. Unfortunately, it's less suited to watching with larger groups because it has narrow viewing angles that make the image look washed out from the side.

Pros
  • Excellent contrast ratio.
  • Fast response time.
  • Great peak brightness.
  • Receives VRR support after a firmware update.
Cons
  • Narrow viewing angles.
  • VRR disables the local dimming feature.
8.5 Movies

The Sony X900H is excellent for watching movies. It has a high native contrast ratio, combined with a full-array local dimming feature, that produces deep, uniform blacks. It can also upscale low-resolution movies without issue, and it removes judder from any source. That said, there's some stuttering in low frame rate content because of its fast response time.

Pros
  • Excellent contrast ratio.
  • Good local dimming.
  • Excellent black uniformity.
Cons
  • Some stutter in lower frame rate content.
7.8 TV Shows

The Sony X900H is good for watching TV shows. It has decent reflection handling, and it gets bright enough to overcome glare, so it's well-suited to watching TV in the daytime. It can also upscale lower-resolution content from cable boxes without issue. On the other hand, it's not recommended for wide seating arrangements because its narrow viewing angles make the image look washed out from the side.

Pros
  • Great peak brightness.
  • Decent reflection handling.
Cons
  • Narrow viewing angles.
7.6 Sports

The Sony X900H is good for watching sports. It has an impressive response time, making motion look clear in fast-moving content. It also has decent reflection handling and is bright enough to fight glare in well-lit rooms. It's not ideal if you like watching the game with a large group, though, since the image quickly loses accuracy when viewed from the side.

Pros
  • Fast response time.
  • Great peak brightness.
  • Decent reflection handling.
Cons
  • Narrow viewing angles.
8.5 Video Games

The Sony X900H is an excellent TV for gaming. Motion looks clear thanks to the fast response time, and it has a remarkably low input lag. If you prefer gaming in the dark, its high contrast ratio and good local dimming produce deep blacks. It also has two HDMI 2.1 ports for advanced consoles, and it has FreeSync and HDMI Forum VRR support once you update it to its latest firmware.

Pros
  • Excellent contrast ratio.
  • Low input lag.
  • Fast response time.
  • Receives VRR support after a firmware update.
Cons
  • VRR disables the local dimming feature.
8.1 HDR Movies

The Sony X900H is great for watching HDR movies. It has a wide color gamut for HDR and gets reasonably bright, although HDR content looks best in dark to moderately lit rooms. Its high contrast ratio produces deep inky blacks, and it has full-array local dimming to further improve black levels. Unfortunately, low frame rate content stutters a bit due to the TV's fast response time.

Pros
  • Excellent contrast ratio.
  • Good local dimming.
  • Excellent black uniformity.
  • Receives VRR support after a firmware update.
Cons
  • Some stutter in lower frame rate content.
8.4 HDR Gaming

The Sony X900H is impressive for HDR gaming. Its gaming performance is impressive thanks to its fast response time and low input lag, which stays low even in HDR. It has a wide color gamut and gets bright enough to bring out some highlights. HDR content looks especially good in the dark because of its high contrast ratio. Unfortunately, it can't support a 4k @ 120Hz signal and Dolby Vision at the same time, although 4k @ 120Hz still works with HDR10. It also supports VRR, but not with Dolby Vision or the local dimming feature.

Pros
  • Excellent contrast ratio.
  • Low input lag.
  • Fast response time.
Cons
  • VRR disables the local dimming feature.
  • Can't do 4k @ 120Hz and Dolby Vision at the same time.
8.0 PC Monitor

The Sony X900H is great for use as a PC monitor. It can display proper chroma 4:4:4, which is important for text clarity, and it has a remarkably low input lag, making for a responsive desktop experience. It also has a fast response time so there's minimal blur behind fast-moving objects like a mouse cursor. Unfortunately, though, it has narrow viewing angles, so the image looks washed out at the edges of the screen if you sit up close.

Pros
  • Low input lag.
  • Fast response time.
  • Decent reflection handling.
Cons
  • Narrow viewing angles.

Market Context

The Sony X900H is a mid-range LED TV that replaces both the Sony X850G from 2019 and the Sony X900F from 2018, and it sits just right below the Sony X950H in the 2020 lineup. It competes with the Samsung Q70/Q70T QLED, Vizio P Series Quantum 2020, and the LG NANO90.

Design
Design
Style
Curved No

The Sony X900H has a sleek design, very similar to the Sony X950H. The metal feet are simple and hold the TV well, although you can't adjust their position to suit smaller tables. The back has some visible screws in the corners, but overall the TV looks nice and should look good in any living room.

Design
Stand

The metal feet slide into the TV itself instead of being screwed on, making setup easier. It has a wide footprint, but there's plenty of space in front for a soundbar without obstructing the screen.

Footprint of the 55 inch TV: 41.8" x 13.2"

Design
Back
Wall Mount VESA 300x300

The back of the TV looks very similar to the Sony X950H, with the same horizontal brushed texture. There are clips included in the box to tie the cables to the feet for cable management.

Design
Borders
Borders 0.35" (0.9 cm)

The borders are thin and aren't distracting.

Design
Thickness
Max Thickness 2.80" (7.1 cm)

The Sony X900H is a bit thicker than most premium TVs we've tested in 2020, but it shouldn't stick out when wall-mounted. The inputs are side-facing, making them easier to access when wall-mounted compared to the Sony X900F.

Build Quality

This TV has great build quality. It feels well-built and doesn't wobble much, as the metal stand supports the TV well. However, the plastic near the inputs flexes a bit. There are some visible screws where the back panel attaches to the borders, and there's a bit more give in this area, but it isn't very noticeable and shouldn't be an issue for most people.

Update 08/16/2021: We retested the Sony X900H with the latest firmware, PKG6.0466.0059NAA. Contrast with local dimming has improved a bit, but it's not a noticeable difference.

The Sony X900H has an excellent native contrast ratio, although contrast may vary between units. It's higher than that of the Sony X950H, as it doesn't have Sony's 'X-Wide Angle' layer, which has the side effect of lowering the contrast ratio. The local dimming improves the contrast a bit, but not by much. That said, blacks still look deep, making it a great choice for dark room viewing. If you want a TV with an even better contrast ratio, check out the Hisense H9G.

Update 11/01/2021: We rechecked the peak brightness after updating to the final VRR firmware, v6.1534, but nothing changed.

Update 10/26/2021: We retested the peak brightness with the latest firmware, in the new 'Enhanced format (VRR)' mode. It's less bright overall than our posted brightness measurements because local dimming isn't available in this mode. We compare the brightness in the VRR mode with the brightness in 'Enhanced format' with local dimming disabled and found that there's no difference at all.

Update 08/16/2021: We retested the Sony X900H with the latest firmware, PKG6.0466.0059NAA. SDR peak brightness decreased a tiny bit overall, but it's not a noticeable difference. On the other hand, the TV isn't dimming small highlights as much anymore, so the 2% windows are closer to other scenes.

This TV has great SDR peak brightness. It's more than enough to fight glare, so you shouldn't have any issues using the TV in a well-lit room. However, the brightness varies depending on the content, and small areas are dimmer, as seen in the 2% and 10% windows.

We measured the SDR peak brightness after calibration, using the 'Custom' Picture Mode. Local Dimming and X-tended Dynamic Range were both set to 'High'.

If you want an even brighter image and don't mind losing accuracy, we reached 638 cd/m² in the 25% window using the 'Vivid' Picture Mode, with Local Dimming and X-tended Dynamic Range on 'High', and Contrast at max.

Update 08/16/2021: We retested the Sony X900H with the latest firmware, PKG6.0466.0059NAA. Someone had reported that the latest firmware broke auto local dimming and that it was now necessary to toggle the local dimming feature between 'High' and 'Medium' for it to work properly again. We tried to reproduce this issue, but our unit doesn't appear to be affected by this bug.

Update 06/22/2021: We've added two new videos demonstrating the local dimming feature with real content.

The full-array local dimming is good. It looks very similar to the Sony X950H, but with less blooming. There's a bit of dimming, though, and some small details are crushed in darker areas. It's good at making highlights in the background pop without being overly distracting; however, it doesn't handle highlights in the foreground as well as the X950H.

Update 10/08/2021: The Sony X900H received VRR support after an update to firmware PKG6.1288.0155NAA. For it to work, you need to set HDMI Signal Format in the HDMI settings to 'Enhanced Format (VRR)', which disables the local dimming. However, you can still use the local dimming if you set it to 'Enhanced Format' and you're in Game Mode for low input lag.

Update 06/22/2021: We've added two new videos demonstrating the local dimming feature with real content.

Local dimming in 'Game' mode looks and functions the same as it does outside of 'Game' mode.

Update 10/26/2021: We retested the peak brightness with the latest firmware, in the new 'Enhanced format (VRR)' mode. It's less bright overall than our posted brightness measurements because local dimming isn't available in this mode. We compare the brightness in the VRR mode with the brightness in 'Enhanced format' with local dimming disabled and found that there's no difference at all.

Update 08/16/2021: We retested the Sony X900H with the latest firmware, PKG6.0466.0059NAA. With the latest firmware, the TV is slightly dimmer in HDR, but it's not a noticeable difference.

Update 06/22/2021: We've retested the HDR peak brightness with Local Dimming set to 'Medium'. In that mode, the 2% and 10% windows aren't dimmed by the algorithms, resulting in a more consistent peak brightness across different content, but some scenes aren't as bright.

Update 03/12/2021: We've retested the HDR peak brightness with the latest firmware (version PKG6.0414.0055NAA). There's a slight drop in the real scene brightness, from 556 cd/m² to 526 cd/m². Overall, the 2% windows are a bit dimmer, while all the other windows are slightly brighter. The ABL result increased from 0.050 to 0.053. The score has been adjusted accordingly.

The HDR brightness is adequate. It gets bright enough to deliver a fairly good HDR experience, especially if you're watching in a dark to moderately lit room, but it doesn't look as punchy in a bright room setting. The overall brightness of scenes is good, as the EOTF follows the target almost perfectly but rolls off toward the TV's peak brightness, meaning that highlights can't appear quite as bright as intended. The brightness also varies a lot depending on the content with Local Dimming set to 'High'. If this variation bothers you, setting it to 'Medium' results in less variation in peak brightness, but also a slightly dimmer image in some cases. If you want a TV with exceptionally high brightness in HDR, check out the Samsung QN85A QLED.

We measured the HDR brightness before calibration, using the 'Custom' Picture Mode, 'Expert 2' Color Temperature, and with Local Dimming and X-tended Dynamic Range set to 'High'.

If you find HDR content too dim, you can make it brighter by using the 'Vivid' Picture Mode, with Local Dimming, X-tended Dynamic Range, and Advanced Contrast Enhancer all set to 'High'. These settings result in a much brighter image, as you can see in this EOTF.

Update 08/16/2021: We retested the Sony X900H with the latest firmware, PKG6.0466.0059NAA. With the latest firmware the TV is slightly dimmer in HDR, but it's not a noticeable difference.

Update 03/12/2021: We've retested the HDR brightness in Game Mode with the latest firmware (version PKG6.0414.0055NAA). The real scene brightness dropped from 688 cd/m² to 669 cd/m². All windows are slightly dimmer but shouldn't be noticeable. The most notable changes are in the 2% peak and sustained windows, both losing roughly 50 cd/m². The ABL result increased from 0.030 to 0.035. The score has been adjusted accordingly.

In 'Game' mode, HDR is somewhat brighter. This is especially noticeable in real scenes. As with 'Game' mode turned off, the brightness varies quite a bit depending on the content.

We measured 'Game' mode HDR brightness after calibration, using the 'Game' Picture Mode with Local Dimming and X-tended Dynamic Range set to 'High' and the Color Temperature set to 'Expert 1'. All extra settings were turned off.

The Sony X900H has excellent black uniformity, but this may vary between units. Without local dimming, the entire screen looks a bit grayish, and there's only some faint clouding around the top and bottom edges of the screen. With local dimming enabled, uniformity is much better throughout the screen, and surprisingly, there's very little blooming around the test cross.

This TV has an optional Black Frame Insertion feature to help reduce motion blur. Unfortunately, the backlight's minimum flicker frequency is 120Hz even when playing 60Hz content, which results in some image duplication.

To enable BFI, set Motionflow to 'Custom' and adjust the Clearness slider to your preference.

To activate Sony's X-Motion Clarity Plus feature, which helps to make the image look clearer and brighter in fast-moving scenes, set Motionflow to 'Custom' and adjust the Clearness slider to '1', and the Smoothness slider to '2'.

Update 11/01/2021: We recheck the variable refresh rate range with the final VRR firmware release, v6.1534, and found that nothing has changed. The same issues we noticed early are still present.

Update 10/26/2021: We retested the VRR feature with the latest firmware and found that it's inconsistent at best. It only works with AMD graphics cards, and although it seems to work perfectly at times, the same computer that works one day might not work the next.

Update 10/08/2021: The Sony X900H received VRR support after an update to firmware PKG6.1288.0155NAA. We tested it with our Radeon RX580 and RX6800 PCs, and while neither showed that there's FreeSync support, there wasn't any tearing with our pendulum test video. Unfortunately, it doesn't support G-SYNC as there's screen tearing.

Update 10/27/2020: We updated the TV to the latest firmware version and retested it with an HDMI 2.1 source.

The Sony X900H has FreeSync and HDMI Forum VRR support once you update it to firmware PKG6.1288.0155NAA. You need to set HDMI Signal Format to 'Enhanced Format (VRR)' for it to work, but that disables the local dimming and Dolby Vision support.

Note: Sony has told FlatpanelsHD that the VRR update isn't final, and that users may experience bugs. They said the full update is expected "later this year."

Update 11/01/2021: We rechecked the input lag after updating to the final VRR firmware, v6.1534. The new results are very similar to the previous firmware update.

Update 10/26/2021: We retested the input lag in the new 'Enhanced Format (VRR)' mode. It's slightly higher in this mode, but it's not a noticeable difference.

Update 10/19/2021: We retested the input lag without VRR after the latest update. We found that the input lag didn't change at all with the latest update, and our new measurements are within the margin of error of the test, so we didn't change anything in our review.

Update 10/08/2021: The Sony X900H received VRR support after an update to firmware PKG6.1288.0155NAA. We measured the VRR input lag with our Radeon RX580 PC, but the 1440p VRR test kept crashing. We measured it with our RX6800 PC instead and measured 14.2 ms with 1440p @ 60Hz VRR. We also got 14.3 ms in 1080p @ 120Hz with VRR and 13.3 ms with 4k @ 120Hz VRR using this PC. However, since we don't normally measure the input lag with that PC, we didn't include those results.

This TV has a remarkably low input lag. It's low as long as you're in 'Game' mode, and it's the lowest with 4k @ 120Hz games. PC users can be in either 'Game' or 'Graphics' mode to get the lowest latency. Input lag remains low even when playing at 4k @ 60Hz + 10-bit HDR, but it increases significantly if motion interpolation is enabled, so it isn't recommended. Unfortunately, it's a bit high in VRR, especially with 4k games.

Update 10/08/2021: The latest firmware PKG6.1288.0155NAA that adds VRR support doesn't change the blurry image with a 4k @ 120Hz signal.

Update 08/16/2021: We retested the Sony X900H with the latest firmware, PKG6.0466.0059NAA. Unfortunately, the blur issue with a 4k @ 120Hz signal still hasn't been resolved. We also did a side-by-side comparison with the Sony X950H, as we had received reports that the X900H is blurrier than the X950H, even with regular content. The X950H looks a bit better due to its higher peak brightness and better colors, but image clarity and blurriness is the same.

Update 06/22/2021: We retested 4k @ 120Hz support, and unfortunately, the issue hasn't been fixed yet.

Update 02/15/2021: We previously indicated that 1440p @ 60Hz is supported natively, it is not. It only works through a forced resolution. We've also retested 1440p @ 120Hz, and it still doesn't work. 1080p @ 120Hz works and is supported natively.

Update 11/26/2020: We updated the TV to firmware version PKG6.0414.0055NAA and checked to see if it fixed the issues with chroma 4:4:4 at 4k @ 120Hz. Text looks a bit better, but it's still blurry, as seen in this photo.

Update 10/27/2020: We updated the TV to the latest firmware (version 6.0384) and retested it with an HDMI 2.1 source.

Update 09/30/2020: We've retested the X900H's ability to display proper chroma 4:4:4 with the latest firmware, as we've received reports that it functions in all picture modes. Unfortunately, the results haven't changed. Chroma 4:4:4 is only possible in 'Graphics' or 'Game' mode.

The Sony X900H supports most common resolutions, except for 1440p @ 120Hz. It properly displays 4k @ 120Hz and doesn't skip frames. Chroma 4:4:4 is supported at all resolutions, and only requires that you be in 'Game' or 'Graphics' mode. However, text looks a bit blurry with chroma 4:4:4 at 4k @ 120Hz, as you can see in this photo. For full-bandwidth signals like 4k @ 60 + 10-bit HDR, set HDMI Signal Format to 'Enhanced Format' for the input in use.

Update 11/09/2021: We changed the 'PS5, Variable Refresh Rate' result, as the TV now supports VRR.

Update 11/01/2021: We retested the X900H with the latest firmware update, v6.1534. There are still issues with 4k @ 120Hz gaming, and it's still halving the resolution in games, displaying at 3840 x 1080.

Update 10/08/2021: The Sony X900H received VRR support after an update to firmware PKG6.1288.0155NAA. It was also supposed to receive ALLM support with the same update, but once you set HDMI Signal Format to 'Enhanced Format (VRR)', it stays in Game Mode, so it doesn't have to change in and out of Game Mode when you play a game. However, we noticed with Destiny 2 on the Xbox Series X that the resolution is reduced to 3840x1080 and the 'Open Director' box flashes between white and gray, which you can see here.

The Sony X900H has two HDMI 2.1 ports (ports 3 and 4), and it supports most, but not all, resolutions for new gaming consoles. When setting the HDMI Signal Format to 'Enhanced Format', it can support a 4k @ 120Hz signal but not Dolby Vision, as you can see here. However, when it's set to 'Enhanced Format (Dolby Vision)', it can't support a 4k @ 120Hz signal, as seen here. This, unfortunately, means that users have to choose between 4k @ 120Hz or Dolby Vision when using the Xbox Series X. For VRR, you have to set it to 'Enhanced Format (VRR)', and that disables the local dimming and Dolby Vision.

This TV has a decent frequency response. The sound profile is reasonably well-balanced and dialogue sounds clear. The bass is punchy, but it doesn't produce a deep rumbling sound. It gets very loud without causing too many compression artifacts, which is great for large or noisy environments. The 65 inch, 75 inch, and 85 inch sizes of this TV have a different speaker configuration and are expected to have better performance.

Differences Between Sizes And Variants

We tested the 55 inch Sony X900H (XBR55X900H), and for the most part, we expect our review to be valid for the 65 inch (XBR65X900H), the 75 inch (XBR75X900H), and the 85 inch (XBR85X900H). It's sold as the Sony X90CH at Costco. In Europe, there's also the XH9296 and the XH9096. Both are basically the same TV as the X900H, but they come with a two-way position stand to accommodate smaller tables. Also, the 65 inch size and larger of the X900H have a different speaker configuration and are expected to have better performance.

Size North America Model Costco Model EU Model
55" XBR55X900H XBR55X90CH   KD-55XH9005

If someone comes across a different type of panel or if their Sony X900H doesn't correspond to our review, let us know and we will update the review. Note that some tests, such as the gray uniformity, may vary between individual units.

Our unit of the X900H was manufactured in May 2020; you can see the label here.

Compared To Other TVs

Comparison picture

Top left: Sony X800H (XBR55X800H). Bottom left: Sony X900F (XBR55X900F). Middle: Sony X900H (XBR55X900H). Top right: Samsung Q70/Q70R QLED (QN55Q70RAFXZA). Bottom right: LG C9 OLED (OLED55C9PUA).

The Sony X900H is an overall great TV for most uses. It's very similar to its sibling, the Sony X950H, but is a better option for gaming due to its lower input lag. There are some tradeoffs, though, as the X900H doesn't get as bright and has narrower viewing angles compared to the X950H. For other options, check out our recommendations for the best TVs, the best 4k HDR TVs, and the best 4k gaming TVs.

Sony X90J
50" 55" 65" 75"

The Sony X90J is the Sony X900H's successor. They're very similar overall, but there are a few differences. Although both TVs use a VA panel, the X90J has a higher contrast ratio, which means it can display deeper blacks. Its color gamut isn't as good as the X900H's, but it gets significantly brighter in HDR to make highlights pop, and its brightness is more consistent due to a less aggressive Automatic Brightness Limiter (ABL).

Sony X950H
49" 55" 65" 75" 85"

The Sony X950H is slightly better than the Sony X900H overall. The X950H has better viewing angles, reflection handling, and it delivers a better HDR experience, as it has a better HDR color gamut and it can get brighter. However, the X900H has a higher contrast ratio since it doesn't have the 'X-Wide Angle' layer, and it has a lower input lag. Also, the X900H has more gaming features like HDMI 2.1 inputs and VRR support.

Sony X85J
43" 50" 55" 65" 75" 85"

The Sony X900H and the Sony X85J are very similar overall. The X85J has a higher native contrast ratio, but the X900H has a full array local dimming feature that can reduce blooming in dark scenes and improve contrast. On the other hand, the X85J has a flicker-free backlight, and the more recent Google TV interface is a bit faster than the older Android TV 9.0 interface on the X900H.

Hisense U8G
55" 65"

The Hisense U8G is better than the Sony X900H. The Hisense has better reflection handling, higher peak brightness, better contrast, and a better local dimming feature. On the other hand, the Sony has better gray uniformity, and there's significantly less banding in areas of similar color.

Samsung Q80/Q80T QLED
49" 50" 55" 65" 75" 85"

For most uses, the Samsung Q80/Q80T QLED is better than the Sony X900H. The Samsung has a faster response time, lower input lag, and a wider VRR range, making it a better option for gaming. The Samsung also gets brighter in HDR content to make highlights pop, and its reflection handling is significantly better. However, the Sony has a higher contrast ratio and better local dimming, so it's a little better for dark room viewing.

Sony X91J
85"

The Sony X91J uses the same processor as the Sony X900H, and the 85 inch X91J performs a lot like the 55 inch X900H we tested. The local dimming features on each look similar to each other, but because the X900H has a smaller screen, the dimming zones aren't as big, so there's more blooming on the X91J. The X900H we tested currently has functional VRR support, unlike the X91J, but it doesn't work at all times, and Sony has said their TVs will receive full VRR functionality after a firmware update. Other than that, they're very similar even though the X91J is a newer model.

Sony X800H
43" 49" 55" 65" 75" 85"

The Sony X900H is significantly better than the Sony X800H. The X900H has a much higher contrast ratio due to its VA panel, it has local dimming, and it gets brighter overall. Response time is faster on the X900H; however, the X800H has lower input lag, and its IPS panel has wider viewing angles.

LG C1 OLED
48" 55" 65" 77" 83"

The Sony X900H and the LG C1 OLED are different types of TVs. The Sony has an LED panel while the LG has an OLED screen, and each has pros and cons. The OLED delivers perfect blacks thanks to its near-infinite contrast, and it has much wider viewing angles. However, the LED screen gets brighter and doesn't suffer from the risk of burn-in. In terms of features, the LG is better for gaming because it has a wider VRR range and lower input lag with VRR enabled.

Sony X80J
43" 50" 55" 65" 75"

The Sony X80J and the Sony X900H use different panels, each with its advantages and disadvantages. Overall, though, the X900H is a step up from the X80J. The X900H uses a VA panel with a high contrast ratio and full-array local dimming, gets brighter and has more features, and has a slightly faster response time. It also has two HDMI 2.1 ports and VRR support once you update it to its latest firmware.

LG CX OLED
48" 55" 65" 77"

The LG CX OLED is better than the Sony X900H. The LG is an OLED TV that can produce perfect blacks, which the Sony can't. The LG has wider viewing angles, better reflection handling, and its near-instantaneous response time results in almost no motion blur. They both support VRR, but the CX has a wider range.

Samsung Q70/Q70T QLED
55" 65" 75" 82" 85"

Overall, the Sony X900H performs better than the Samsung Q70/Q70T QLED. The Sony has full-array local dimming, and it has a much better response time, resulting in smoother motion. The Sony also feels better built. That said, the Samsung has a much better contrast ratio, which delivers deeper blacks.

Samsung Q70/Q70A QLED
55" 65" 75" 85"

The Sony X900H and the Samsung Q70/Q70A QLED both perform well, although the Sony delivers better picture quality. While the Samsung has a higher native contrast ratio, the Sony's is still high, and it has a full-array local dimming feature to improve black levels. The Samsung has a lower input lag and comes with a wider VRR range.

Samsung Q60/Q60T QLED
43" 50" 55" 58" 65" 75" 82" 85"

The Sony X900H is better overall than the Samsung Q60/Q60T QLED. The Sony has a local dimming feature that allows it to display deep blacks, and it also gets brighter in HDR, so highlights pop the way the creator intended. The Sony also has a 120Hz panel, which results in a much quicker response time and smoother motion, and it has HDMI 2.1 support, which is great for next-gen console gamers.

Sony X950G
55" 65" 75" 85"

The Sony X900H and the Sony X950G have nearly identical overall performance. The X900H has better local dimming, better screen uniformity, and its input lag is lower. However, the X950G gets brighter in SDR and HDR, and it has much better reflection handling.

Hisense H9G
55" 65"

The Hisense H9G is somewhat better overall than the Sony X900H. The Hisense has a better contrast ratio, gets brighter, has much better reflection handling, and has a quicker response time. That said, the Sony has much better out-of-the-box color accuracy, it's better-built, and it has better gradient handling.

Samsung TU8000
43" 50" 55" 65" 75" 85"

The Sony X900H is better overall than the Samsung TU8000. The Sony is an upper-mid range TV that gets much brighter, and it has a full-array local dimming feature, which the Samsung doesn't have. The Sony also has HDMI 2.1 support for gaming, displays a wide color gamut, and gets much brighter in HDR to deliver a better HDR experience. On the other hand, the budget-friendly Samsung has an improved contrast ratio, but this can vary between units.

Samsung Q80/Q80A QLED
55" 65" 75" 85"

The Sony X900H is better than the Samsung Q80/Q80A QLED, mainly because they have different panels. The Sony's VA panel has a higher contrast ratio that lets it display deep blacks, and the local dimming feature is also better. However, the Samsung has an IPS-like panel with wider viewing angles. It also gets brighter, especially in HDR, and it has more gaming features like a wider VRR range.

Hisense U7G
55" 65" 75"

The Sony X900H is slightly better than the Hisense U7G for most users. The Sony has better black uniformity, a better local dimming feature, better gray uniformity, and it's more accurate out of the box. The Hisense is brighter, and it has better contrast. The Hisense has a wider VRR range, but the Sony has a quicker response time.

Samsung Q90/Q90T QLED
55" 65" 75" 85"

The Samsung Q90/Q90T QLED and the Sony X900H are two great TVs, although the Samsung is better for most uses. The Samsung gets much brighter, especially in HDR, and combined with its better local dimming feature, it offers a superior HDR viewing experience. It also has wider viewing angles thanks to Samsung's 'Ultra Viewing Angle', but that also means the Sony has a better native contrast ratio.

Sony X750H
55" 65" 75"

The Sony X900H sits higher in the lineup than the Sony X750H and has much better performance. The X900H delivers a better HDR experience because it gets much brighter and has a full-array local dimming feature that does a good job at improving its contrast. The X900H also has more gaming features like HDMI 2.1 support, allowing you to play 4k @ 120Hz games, which the X750H can't do.

Samsung Q70/Q70R QLED
49" 55" 65" 75" 82" 85"

The Samsung Q70/Q70R QLED and the Sony X900H both perform very similarly. The Samsung has a significantly better contrast ratio and black uniformity, giving it better dark room performance, while the Sony has better out-of-the-box color accuracy and better gray uniformity. Serious gamers will appreciate the native FreeSync support on the Samsung.

55" 65" 75" 86"

The Sony X900H is better overall than the LG NANO90 2021, mainly because they use different panel types. The Sony has a VA panel with a much higher contrast ratio and significantly better local dimming, so it's a better choice for watching movies in dark rooms. The Sony gets brighter, but the LG has much better reflection handling. Each TV has a 120Hz panel with HDMI 2.1 and VRR support, but the VRR range is wider on the LG. Lastly, the LG has an IPS panel with wider viewing angles, so the image remains accurate when viewing from the side.

Samsung QN85A QLED
55" 65" 75" 85"

The Samsung QN85A QLED uses a different panel type than the Sony X900H, but they're great TVs overall. The 55 inch version of the Samsung uses an IPS panel with a low native contrast ratio and wider viewing angles, while the Sony uses a VA panel with a high contrast ratio and poor viewing angles. The Samsung is better suited to wider seating arrangements, and it has a wider VRR range if that's important to you. The Samsung also gets much brighter and can make HDR highlights pop, which the Sony may struggle with.

TCL 6 Series/R646 2021 QLED
55" 65" 75"

The Sony X900H and the TCL 6 Series/R646 2021 QLED are two great TVs. The TCL features Mini LED that allows it to get brighter and, combined with the better reflection handling, is a better choice for well-lit rooms. Despite the Mini LED backlighting, the Sony has a better local dimming feature because it doesn't raise the black levels like on the TCL. They both have similar gaming features with HDMI 2.1 inputs, a quick response time, and low input lag. Both TVs have VRR support, but you have to update the Sony to receive it.

Sony A80J OLED
55" 65" 77"

The Sony A80J OLED is better than the Sony X900H, mostly thanks to its OLED panel and near-infinite contrast ratio. The X900H is still a great TV, with a high contrast ratio and higher brightness than the A80J. It's a good option if you're worried about permanent burn-in with OLEDs. That said, the A80J has a faster response time, wider viewing angles, wider color gamut, and generally outperforms the X900H.

LG NANO85

The Sony X900H is better overall than the LG NANO90 2020. The Sony has a VA panel, producing much deeper blacks, and it has a better full-array local dimming feature. It also gets brighter, has more accurate colors, and it has a more uniform screen. However, the LG has wider viewing angles due to its IPS panel, so it may be preferable if you have a wide seating arrangement.

The Sony X900H is better than the Samsung The Frame 2021 overall, especially for watching movies and HDR content. It's because it has a full-array local dimming feature, gets a bit brighter in HDR, and its gradient handling is much better. It has a slightly better response time than the Samsung, but its input lag is higher. Unlike the Sony, the Samsung doesn't support Dolby Vision; it supports HDR10+ instead.

LG BX OLED

The LG BX OLED is much better overall than the Sony X900H, but they have different panel types. The LG has an OLED panel with self-emitting pixels, so it has an infinite contrast ratio and perfect black uniformity. It also has wider viewing angles and a near-instant response time for gaming. On the other hand, the LED panel on the Sony gets much brighter, and it doesn't have the risk of permanent burn-in like the LG.

TCL R745 QLED
85"

The TCL R745 QLED and the Sony X900H are both great TVs. They're each available in 85 inch models and have VA panels with high contrast. They both have local dimming features, but it's better on the Sony because there's less blooming. The Sony is future-proof because it has HDMI 2.1 inputs, which the TCL doesn't, allowing you to play 4k games up to 120fps. The TCL displays a wider color gamut and gets much brighter in HDR, making highlights pop.
