Resolution 4k

The Sony X900H, also known as the X90CH, 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 delivers fast-moving scenes with minimal blur thanks to its fast 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. Unfortunately, its viewing angles are quite narrow, so images look washed out when viewed from the side. Also, while it's advertised as having variable refresh rate support to reduce screen tearing, it isn't functional yet.

Our Verdict

8.0 Mixed Usage

The Sony X900H is a great TV for most uses. It delivers good picture quality thanks to its great contrast ratio, high peak brightness, and wide color gamut. It has a fast response time that results in very little motion blur, and its input lag is low enough to satisfy even serious gamers. HDR content is delivered with vibrant colors and highlights that pop. Unfortunately, it has narrow viewing angles, making it less ideal for large rooms or wide seating arrangements.

Pros
  • Excellent contrast ratio.
  • Fast response time.
  • Great peak brightness.
Cons
  • Sub-par viewing angles.
  • VRR support not yet active.
8.5 Movies

The Sony X900H is excellent for watching movies. Its high native contrast ratio is enhanced by a full-array local dimming feature and, combined with its excellent black uniformity, blacks look deep when viewed in the dark. It upscales lower resolution movies well and can remove judder from all sources. However, it stutters a bit in lower frame rate content due to 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 gets bright enough to combat glare. It upscales lower-resolution content, such as from cable boxes, without any issues. Unfortunately, it has narrow viewing angles, so it isn't ideal for seating arrangements that require you to view from the side. Android TV is easy to use and has plenty of apps, great for those who get their content through streaming services.

Pros
  • Great peak brightness.
  • Decent reflection handling.
Cons
  • Sub-par viewing angles.
7.6 Sports

The Sony X900H is good for watching sports. It has a great response time so fast-moving content looks crisp, and there's almost no dirty screen effect in the center. It's a good choice for well-lit rooms as it has great peak brightness and decent reflection handling. Sadly, its narrow viewing angle means it isn't ideal for watching the big game with a large group.

Pros
  • Fast response time.
  • Great peak brightness.
  • Decent reflection handling.
Cons
  • Sub-par viewing angles.
8.1 Video Games

The Sony X900H is great for gaming. It has very low input lag and a 120Hz refresh rate to provide a responsive gaming experience, and its fast response time makes fast-moving scenes look crisp. It's well-suited for dark room gaming, as it has a high contrast ratio and full-array local dimming to produce deep blacks.

Pros
  • Excellent contrast ratio.
  • Low input lag.
  • Fast response time.
Cons
  • VRR support not yet active.
8.1 HDR Movies

The Sony X900H is great for watching movies in HDR. It has a high native contrast ratio that allows it to produce deep blacks, and a good full-array local dimming feature to further improve black levels. It has a good HDR color gamut to produce rich colors and gets bright enough to bring out some highlights, especially when viewed in a dark environment. However, low frame rate content can stutter a bit due to the TV's fast response time.

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

The Sony X900H is good for gaming in HDR. Its input lag is very low and remains low even when playing in 4k with 10-bit HDR. It has a good HDR color gamut and gets decently bright, enough to make some highlights pop. Sadly, its advertised VRR support isn't active yet and will only be made available in a future firmware update.

Pros
  • Excellent contrast ratio.
  • Low input lag.
  • Fast response time.
Cons
  • VRR support not yet active.

The Sony X900H is good to use as a PC monitor. It can display the most common resolutions and proper chroma 4:4:4 for optimal text clarity. It has low input lag and fast response time to provide a smooth and responsive desktop experience. It handles reflections decently well and gets bright enough to combat glare. Unfortunately, it has narrow viewing angles, so the edges of the screen may look washed out if you sit too close.

Pros
  • Low input lag.
  • Fast response time.
  • Decent reflection handling.
Cons
  • Sub-par 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.

Curved No

The Sony X900H looks a lot like the Sony X950H and has an outstanding design. The metal feet hold the TV well, but unlike the X950H, you can't change their position to accommodate smaller tables. It has thin bezels on three sides and a slightly thicker bottom bezel. There are some visible screws in the back where the back panel meets the borders, but the TV still looks very nice overall.

Design
Stand

The metal feet are slid into the TV, making the setup process a bit easier as you don't need to screw anything on. It has a wide footprint, and there's enough space to put stuff in front, like a soundbar. The feet support the TV well.

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

The back of this 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.

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.

The Sony X900H has an excellent native contrast ratio. 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. Note that contrast may vary between units. If you want a TV with an even better contrast ratio, check out the Hisense H9G.

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.

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 a lot depending on the content and small areas are more dim, 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.

The HDR peak brightness is decent. There's a lot of variance in the brightness with different content. It gets bright enough to deliver a pretty good HDR experience, especially if you're viewing in a dark to moderately-lit room; it just doesn't look as punchy in a bright room setting. Like the SDR peak brightness, the TV dims the 2% and 10% windows.

We measured the HDR peak 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 don't mind losing image accuracy, you can get a brighter image by setting the Color Temperature to 'Expert 2', Contrast to max, and Local Dimming and X-tended Dynamic Range to 'High'. With these settings, we reached 803 cd/m² in the 25% window.

Like most VA panels, this TV has narrow viewing angles, and unfortunately, it doesn't have Sony's 'X-Wide Angle' layer to improve it. The image degrades fairly quickly when moving off-center, so it's not the best option for large rooms or wide seating arrangements.

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.

The color accuracy is excellent out-of-the-box, but this may vary between units. There are minor inaccuracies with blue and red, and the white balance is only slightly off. The color temperature is very close to our 6500K target. Gamma is also close to the 2.2 target, but most scenes are too dark and bright scenes are over-brightened.

This TV has a good color gamut for HDR content. It has excellent coverage of the DCI P3 color space used in most HDR content, but coverage of the wider Rec. 2020 is just okay. The EOTF follows the target almost perfectly until the roll-off, and the 'Game' mode EOTF is nearly identical, which you can see here.

If you find HDR content still 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 results in a much brighter image, as you can see in this EOTF.

If you want a similar TV with a better color gamut, check out the Vizio P Series Quantum 2020.

This TV has an optional Black Frame Insertion (BFI) 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.

The Sony X900H can interpolate lower frame rate content up to 120fps to make motion look smoother, also known as the 'Soap Opera Effect'. Motion looks good when enabled and we didn't notice any issues.

If you want to use motion interpolation on native 60fps content, set Motionflow to 'Custom', with the Smoothness slider set to 'Max' and the Clearness slider set to 'Min'. For native 30fps content, set Cinemotion to 'Auto'.

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

This TV has excellent 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, we'll have to wait until Sony releases the firmware update that enables VRR to test the input lag with VRR enabled, and the 'Auto Low Latency Mode' should also be enabled in the same update.
