The Samsung Q80R is an excellent 4k LED TV with impressive picture quality. It delivers deep blacks thanks to the high native contrast ratio, excellent black uniformity, and very good local dimming support. It's a very bright TV with a wide color gamut that delivers HDR content with rich colors and highlights that pop. It has decent viewing angles, despite being a VA panel TV, thanks to the 'Ultra Viewing Angle' technology. The TV has remarkable motion handling and produces crisp motion with minimal blur. It has a very low input lag and supports FreeSync for more consistent motion during gaming.
The Samsung Q80R is an excellent TV for mixed usage. It performs just as well in a dark room, for movies and HDR content, and in a bright room for sports or TV shows. It has a fast response time, a low input lag, and supports some advanced gaming features that will please gamers, no matter if you're gaming on a console or a PC.
The Q80R is an excellent TV for watching movies. It produces deep, uniform blacks that enhance the picture quality in a dark room. It can remove 24p judder from any source, and has an optional motion interpolation feature for soap opera effect fans, which also comes in handy if you wish to remove stutter in movies.
The Q80 is a fantastic TV for watching TV shows. If you watch shows during the day, it can get really bright and it does a fantastic job at handling reflections, so it's suitable for any bright room. Although most VA panel TVs don't have good viewing angles, the 'Ultra Viewing Angle' layer gives it a decent viewing angle, so your whole family will be able to sit around the TV and enjoy your favorite show without losing too much image accuracy.
The Q80R is excellent for watching sports. It's a very bright TV with remarkable reflection handling, so you can place it in a bright room with many lights or windows and still enjoy a great picture. It has a very fast response time, so fast action looks crisp and the image remains accurate for wider viewing angles. This is great for watching the big game with a group of friends. Finally, the TV has decent great uniformity that won't spoil your sports-watching experience.
Outstanding TV for playing video games. The input lag is remarkably low and the TV responds almost immediately to your actions. The fast response time delivers crisp motion and the TV is packed with gaming goodies. It supports FreeSync for nearly tear-free gaming, low input lag with motion interpolation, and a convenient Auto Low Latency Mode.
The Q80R delivers an excellent HDR movie watching experience. The high contrast ratio, excellent black uniformity, and good local dimming support produce deep blacks in a dark room where HDR is meant to be seen. The wide color gamut and high HDR peak brightness deliver HDR content with rich and vivid colors and highlights that stand out.
The Samsung Q80R is a remarkable TV for playing HDR games. It has a very low input lag in HDR and responds immediately to your actions. HDR games are displayed remarkably well, full of vivid colors and bright highlights, thanks to the wide color gamut and excellent HDR peak brightness.
The Q80R is an excellent TV for use as a PC monitor. It has a very low input lag and it reacts instantly to your actions. The response time is very fast and thus only a small blur trail follows fast-moving content. It can display proper chroma 4:4:4 and has decent viewing angles that deliver a uniform image at the edges when you sit up close. As a VA panel, this TV appears to be immune to temporary image retention or permanent burn-in.
The Samsung Q80's design is excellent. Its body is very similar to the Q70R, except for the metallic borders and the stand, which are different. The stand provides good support for the TV and the back of the legs are hollow to provide a path for cable management. However, the TV wobbles significantly more than the Q70R when nudged. The Q80R is a very thin TV and it won't stick out much if you decide to wall-mount it. Unfortunately, its not compatible with a no-gap wall mount to put it flush to the wall. The build quality is excellent, and you should have no issues with it.
The stand supports the TV well but won't prevent wobbling if you nudge the TV. It takes up a lot of space, but it's not as wide as the TV.
Footprint of the 55" stand: 34.8" x 10.0".
The borders of the TV look nice and the bezel is very thin. The borders are made of metal and have a slightly lighter tint than the Q70R.
Excellent build quality, similar to the Q70R. The TV feels solid but it wobbles a bit on its stand, although this shouldn't be too much of an issue.
The Samsung Q80 has a great native contrast ratio. It is, however, lower than most TVs with VA panels. This is because of the TV's 'Ultra Viewing Angle' layer that improves the viewing angles at the expense of contrast ratio. This is very similar to the Samsung Q90R and the Q900R. The native contrast ratio of this TV measures slightly better than other TVs we've tested that support similar viewing angle boosting technology.
Unfortunately, just like the Q70R and the Q90R, the TV's local dimming can't be completely disabled in the normal settings menu. In order to measure the native contrast ratio, we had to disable PC Mode Dimming in the TV's service menu, and then activate PC Mode and Game Mode at the same time.
The Q80 has a very good local dimming feature. It's better than the Q70R and similar to the Q9FN. Unfortunately, it doesn't dim small objects well, but when bright highlights move across the screen, there's a good transition from one dimming zone to the next. When viewed from the side, you might notice some blooming.
When there are subtitles on the screen, there might be noticeable brightness changes in the scene. This is normal for Samsung TVs with local dimming features.
You can't disable the local dimming feature through the regular menus on the TV. Local Dimming was set to 'High' for these tests.
Update 08/02/2019: We have retested the Q80 with the latest firmware, and the SDR peak brightness has increased a bit. We've updated our measurements and scores.
The TV has excellent peak brightness and it's suitable for a bright room as it will easily fight glare. The Samsung Q80 isn't as bright as the Q90R, but it's a little brighter than the Q8FN in real scenes and in the larger window sizes. The Q8FN is brighter in smaller highlights.
We measured the peak brightness after calibration, using the 'Movie' Picture Mode and 'Warm 2' Color Tone, with Local Dimming set to 'High' and Gamma set to '2.2'. We use these settings because they give the most accurate image, and this is the maximum brightness that you can get with these settings.
If you don't care about image accuracy, you can obtain higher brightness levels. We were able to reach about 1250 nits on our 10% window, which lasted for at least 10 seconds before the ABL dimmed the image.
Update 08/02/2019: We have retested the Q80R with the latest firmware, and the HDR peak brightness has increased a bit. We've updated our measurements and scores.
We measured the peak brightness before calibration, using the 'Movie' Picture Mode and 'Warm 2' Color Tone, with Local Dimming set to 'High.' We use these settings because they give the most accurate image and this is the maximum brightness that you can get with these settings.
If you don't care about image accuracy, you can obtain higher brightness levels. We were able to momentarily reach a brightness of about 1650 nits on the 10% window before the ABL dimmed the image.
Decent gray uniformity. The Q80 gets a bit darker around the edges of the screen, and even more in the corners. There's minor dirty screen effect, which might be distracting with fast-moving objects, but it shouldn't be noticeable to most people.
There are no uniformity issues in dark scenes.
The TV has decent viewing angles. The image remains accurate at wide angles as you move off-center. This is a behavior that is mostly found on IPS panels, and not usually on VA panels like this TV. Just like the Q90R, it has the new 'Ultra Viewing Angle' layer that improves viewing angles at the expense of native contrast ratio. The 'Ultra Viewing Angle' technology appears to work similarly to the 'X-Wide Angle' technology found on the Sony Z9F.
We took our color measurements after calibration, using the 'Movie' Picture Mode and Local Dimming set to 'Low.' Unfortunately, the TV's local dimming can't be completely disabled using the normal settings menu. In order to take our lightness measurements, we disabled PC Mode Dimming in the TV's service menu, and then activated PC Mode and Game Mode at the same time.
We observed some weird diagonal stripes that are visible when you look at the screen from up close and from the left. This isn't noticeable from farther away. We assume that this is due to the optical layer, but it isn't noticeable on our other TVs (the Q90R, the Q900R, or the Z9F) that use this technology. This is the first 55 inch TV that we've tested that uses this optical layer, so we're not sure if the layer in this size of TV has anything to do with the stripes we noticed.
The Samsung Q80 has excellent black uniformity, which is an improvement over the Q8FN. There's a bit of blooming around the center cross and some backlight bleed in the native black uniformity picture, but most people won't notice this with normal content. The uniformity improves with local dimming enabled, as there's less visible backlight bleed but there's still some clouding around the center cross.
This TV's local dimming feature can't be completely disabled in the normal settings menu. For the native black uniformity test, we had to disable PC Mode Dimming then activate PC Mode and Game Mode at the same time, which turned local dimming off.
Fantastic reflection handling. This TV will perform well in any room with a lot of windows or lights and you won't be distracted all that much from reflections. The 'Ultra Viewing Angle' layer diffuses light differently than most TVs, and instead it scatters the reflection across the screen. This may cause some rainbow reflections across the screen, as seen in the 'Bright Room Off' picture. This is better reflection handling than the Q70R, although it's a bit worse than the Q8FN.
Good pre-calibration color accuracy. Most colors should appear as they're supposed to, although there might be some inaccuracies. The gamma curve is above the target of 2.2, so most scenes will be darker than they should. The color temperature is warmer than the expected value of 6500K, meaning most colors will have a red/yellow tint to them. This is most noticeable with the color blue, which is the most inaccurate color pre-calibration.
If you want a TV with better color accuracy out of the box, check out the Samsung Q80T QLED.
10/31/2019: Unfortunately, it would appear that the Q80R isn't compatible with the Auto-Calibration Function.
Excellent accuracy after calibration for the Q80. The white balance dE is almost perfect, and the color dE is so low that most will only spot the remaining inaccuracies with the aid of a colorimeter. The gamma tracks the curve well, and the color temperature is very close to the target of 6500K.
You can see our recommended settings here.
Older, 480p digital content looks good, with no obvious upscaling artifacts or over-sharpening.
720p, like cable TV, is upscaled well. There's no obvious over-softening and no upscaling artifacts.
Upscaling of 1080p content such as Blu-rays or game consoles looks good. The image is sharp and there are no obvious issues.
The 'Movie' EOTF (shown above) is a little brighter at higher stimulus levels until it starts to roll off near the TV's peak brightness. In 'Game' mode, the EOTF is very similar to the 'Movie' mode as we can see here.
Good color volume, but it's much better on the Q8FN. Thanks to its low contrast ratio, it's able to display deep, saturated colors. It can't display some brighter blues, which is normal for most LED TVs.
The gradient of the QN55Q80RAFXZA is good. Some fine banding is noticeable in all dark shades, especially in the dark greens and grays. It is, however, hard to notice in normal content. If banding is bothering you, set Digital Clean View to 'Auto' and it'll remove most of it. Unfortunately, it can also cause some loss of some fine details in certain scenes.
There's no temporary image retention on the Samsung Q80.
We don't expect VA panels to experience permanent image retention, as the VA panel in our long-term test appears immune.
Excellent response time on the Samsung Q80. Gamers will appreciate how clear motion looks on this TV and it's an improvement from the Q8FN. Unfortunately, there's some overshoot in the 0-20% and 0-80% transitions, which affects the motion in dark scenes.
For this test, we turned the Local Dimming feature off so we could get a more consistent reading. Local dimming doesn't affect the response time. Find out how to disable local dimming here.
The Q80 uses PWM dimming to dim the backlight. The flicker frequency is at 960Hz only when the TV is in 'Movie' mode and Auto Motion Plus is disabled. The flicker frequency changes to 120Hz as soon as you set Auto Motion Plus to 'Custom' or 'Auto,' even if you remain in 'Movie' mode. In 'Standard,' 'Dynamic,' 'PC,' 'Game,' or in 'Natural' modes, the flicker is always at 120Hz, similar to the Q70R and the Q90R.
The TV has an excellent black frame insertion feature. It can lower the flicker frequency as low as 60Hz to help make the image crisper. This decreases the picture brightness, and 60Hz flicker can be bothersome to some people.
Just enabling Auto Motion Plus automatically sets the flicker to 120Hz. Setting LED Clear Motion to 'On' further reduces the flicker frequency to 60Hz.
When you're in 'Game' mode, the flicker frequency is always 120Hz. If you enable LED Clear Motion in Game Motion Plus, it'll change the flicker frequency to 60Hz and will make the image even crisper.
The Samsung Q80 can interpolate lower frame rate content up to 120fps. To enable motion interpolation, you must enable Auto Motion Plus and adjust the available sliders.
See here for more information regarding the settings that control the Q80R's motion interpolation feature.
Note that, like many Samsung TVs, simply setting Auto Motion Plus to 'Custom' changes the backlight flicker to 120Hz.
Due to the Q80R's very fast response time, each frame of any low frame rate content, like movies, is held on screen for longer periods of time. This causes the image to appear to stutter. If it bothers you, motion interpolation or optional black frame insertion feature can help.
The Samsung Q80R can remove judder from any source.
See our recommended settings on how to remove judder here.
Update 12/17/2019: A flaw was discovered in the way we were testing for G-SYNC compatibility with TVs. We've corrected the flaw, and have retested the 2019 Samsung and LG TVs, and found that the Q80 doesn't work properly with NVIDIA's current Adaptive Sync drivers.
The TV has a native refresh rate of 120Hz, and like all premium Samsung TVs since 2018 it supports the FreeSync variable refresh rate technology. FreeSync VRR can offer you a nearly tear-free gaming experience, provided you have a compatible AMD card or an Xbox One. 1440p and 1080p have the same excellent VRR range. At 4k, however, the range is narrower at 4k, as the TV only supports up to 4k @ 60Hz.
We tested the TV on 'Game' mode, without interpolation or any other gaming processing setting, and we set FreeSync to 'Ultimate' to obtain the widest possible range.
If FreeSync is enabled on a connected device, auto game mode doesn't work at all; it will always stay in game mode.
Update 08/02/2019: We've retested the TV with the latest firmware, and the input lag has decreased slightly across the board. The TV is no longer skipping frames when sent a 1080p or 1440p @ 120Hz signal. We've updated our numbers and scores.
This TV has an excellent low input lag. The input lag is very similar to the input lag of both the Q90R and the Q70R, and an improvement from the Q8FN. This is great news for gamers. To get the lowest input lag, you need to set the TV to 'Game Mode.' However, when in 'PC Mode,' you get the same low input lag without the need to set the TV to 'Game' mode. To display proper chroma 4:4:4 you must set the TV to 'PC mode.'
Note:When motion interpolation is enabled in 'Game Mode' through the Game Motion Plus menu, the input lag is 37.7ms when you interpolate to 60fps and 43.3ms for 120fps.
To find out more about what settings to use to obtain those numbers, and about the Auto Low Latency Mode, see our recommended settings for Gaming.
Just like the Q90R, the Q70R, and 2018 Samsung TVs, the Q80 doesn't support DTS passthrough or eARC. It likely does support lossy Atmos passthrough from Dolby Digital Plus sources, like the native Netflix app, because there's an Atmos option in its settings.
If you need eARC support, check out the Samsung Q90T.
The Q80R has a decent frequency response. The low-frequency extension (LFE) can get fairly low to have some punch in its bass, but may not be low enough to produce any rumble or thump. Above the LFE, the TV has a well-balanced sound profile, resulting in clear dialogue for your TV shows or movies. This TV can get loud enough for any in-home setting, but not loud enough for noisy environments.
We tested the Q80R with the Adaptive Sound feature enabled, but left Adaptive Volume disabled, as it drastically limited the max volume. This feature could be useful if you find that commercials play at a higher volume than the content you're watching.
Decent distortion performance. The overall amount of harmonic distortion produced is within low limits. Also, there isn't a big jump in THD under heavier loads, which is good.
Although we had no serious issues during our testing, we did encounter the same bug found on the 2019 QLEDs. When you switch the input icon from PC to any other input, the Fit-to-Screen setting doesn't always work. To fix this, you just have to navigate into picture size settings, but you don't need to change anything.
Just like all Samsung TVs we've tested so far, the Q80R has ads in a few places. They appear in both in the app store and on Samsung's Smart Hub and can't be disabled.
Samsung's app store has a very large selection of apps to choose from. The apps on the Samsung Q80R run well, although they aren't always very smooth.
The Samsung Q80R has the same remote as the other Samsung TVs from the 2019 QLED lineup. Without the need for direct line of sight, you won't need to worry about pointing the remote directly at the TV. It has three quick access buttons for Netflix, Amazon Prime Video, and Hulu, and it's compatible with Samsung's voice assistant feature, Bixby. You can do various demands with the voice control, although we couldn't search for a show directly in Netflix with it, but we were able to search in YouTube. Also, it can act as a universal remote for other devices using Samsung's One Remote feature.
Just like the Q70R and the Q90R, the TV controls are located right under the Samsung logo. The keypad has five buttons that serve as a D-pad and allows you to do pretty much anything. You can open the input list, change channels and volume, access the settings, and even launch the Home menu.
If you need to launch the Home menu while you're in an app, press and hold the center button. To close the Home menu, do the same; press and hold the center button.
We tested the 55" (QN55Q80RA) version, AA01/QRQ80. For the most part, we expect our review to be valid for the 65" version (QN65Q80RA) and the 75" version (QN75Q80RA).
There's also an EU-only variant of the TV, the Q85R. The Q85R is advertised as having more local dimming zones and comes along with a One Connect box, but otherwise seems identical to the Q80R. We have not tested this unit so we can not be sure. Note that the UK version of the Q80R appears to have fewer dimming zones than the unit we tested, but we don't know how it performs.
If someone comes across a different type of panel or if their Samsung Q80R doesn't correspond to our review, let us know and we will update the review.
The 55" Q80R we tested was manufactured in Feb. 2019.
The Samsung Q80/Q80T QLED and the Samsung Q80/Q80R QLED are very similar TVs in many respects. The Q80R can get much brighter in HDR, its local dimming performs better, and it has a higher contrast ratio. On the other hand, the Q80T has better color accuracy, a faster response time, and a lower input lag, which is good news for gamers. Both TVs have a 120Hz refresh rate and support VRR to reduce screen tearing when gaming.
The Samsung Q80/Q80R QLED is better than the Samsung Q70/Q70R QLED. The Q80R can handle reflections slightly better and has a wider viewing angle thanks to the 'Ultra Viewing Angle' layer. Its local dimming is better than the Q70R and significantly helps improve dark room performance. The Q70R, on the other hand, has a higher native contrast ratio and can deliver deeper and more uniform blacks, even though its local dimming isn't as effective.
The Samsung Q90R and the Samsung Q80R have very similar performance. The Samsung Q90R has a slightly faster response time, which some enthusiasts might notice when watching sports. Also, the Q90R has more effective local dimming thanks to the greater number of local dimming zones than the Q80R. Although our Q90R test unit was a larger variant, we expect this to be true for the same size variants of the Q80R. All of the other differences are mainly in the design. The Q90R has a One Connect box, supports a no-gap wall mount, and its stand has a smaller footprint.
Overall, the Samsung Q80/Q80R QLED performs better than the Sony X950H. The Q80 has a higher contrast ratio that results in deeper blacks, its local dimming performs better, and it has better viewing angles. The Q80 also has much lower input lag and it supports variable refresh rate technology; however, the X950H has much better color accuracy out of the box.
The Samsung Q80/Q80R QLED is better than the Sony X950G. The Samsung Q80R has slightly better black uniformity, which is important in a dark room. The Q80R can also handle reflections better, and is loaded with gaming goodies like FreeSync Support and low input lag with motion interpolation. Both TVs have a technology that improves viewing angles, but for the Samsung Q80R, this technology is available in all models, whereas for the Sony X950G it's only available in the larger models.
The Samsung Q80/Q80R QLED TV is much better than the Q60/Q60R QLED. The Q80 has a full array local dimming feature and excellent black uniformity, which is great for dark room performance. The Q80 can also get a lot brighter, has significantly better viewing angles, and much better reflection handling.
The LG B9 OLED and the Samsung Q80/Q80R QLED have different panel types, each with their advantages and disadvantages. The B9 has an excellent dark room performance thanks to its perfect blacks. The Q80R can get significantly brighter and can fight the glare of a very bright room. The B9 has better gray uniformity and better viewing angles, but it also has a risk of permanent burn-in when exposed to static content, something that doesn't happen with the Q80R.
The Samsung Q80R is somewhat better than the Samsung Q8FN. The Samsung Q80R has wider viewing angles thanks to the 'Ultra Viewing Angle' layer, so the image remains accurate when viewed from the side. The Samsung Q8FN, on the other hand, has better reflection handling, which is great if you place it in a room with many light sources. The Samsung Q80R has slightly better local dimming performance, which is great when you watch movies, and a slightly lower input lag, great for playing video games.
The Samsung Q80R is marginally better than the Samsung Q9FN. The Samsung Q80R encompasses the 'Ultra Viewing Angle' technology that improves viewing angles at the expense of lower contrast ratio. The contrast ratio on the Q9FN is better, but the overall dark room performance between the two TVs is almost on par. The Q80R has marginally better gray uniformity, which is essential when watching sports, and a somewhat lower input lag, which is great for serious gamers. The Samsung Q9FN handles reflections marginally better thanks to the lack of viewing angle layer.
These are two different types of TVs, each with its advantages and disadvantages. The LG C9 is an OLED TV that delivers an outstanding dark room performance thanks to its perfect blacks. The C9 has wider viewing angles and delivers motion with almost no blur, thanks to the nearly instantaneous response time. The Samsung Q80R doesn't have the burn-in risk of the OLEDs and can get brighter, which is great for a bright room. Finally, the Samsung Q80R has low input lag with motion interpolation.
The Samsung Q80/Q80R QLED is a much better TV than the Samsung RU8000. The Q80R looks and feels much better-built, can get much brighter, has better viewing angles, full-array local dimming, and a wider color gamut. On the other hand, the RU8000 has a better contrast ratio.
These are two different types of TVs, each with their advantages and disadvantages. The LG C8 is an OLED TV with perfect blacks, outstanding dark room performance, and wider viewing angles. The C8 has a slightly better response time and better gray uniformity that help to deliver a better sports performance. The Samsung Q80R doesn't have a permanent burn-in risk and can get brighter in SDR, so it's more suitable for a brighter room. Finally, the Q80R is packed with gaming features, like FreeSync support, that are an attraction to serious gamers.
The Samsung Q90T QLED and the Samsung Q80/Q80R QLED are nearly identical in terms of feature set and overall performance, as the Q90T is a replacement of the Q80R. Other than the added eARC support, the Q90T has a higher HDR peak brightness and a significantly faster response time, resulting in less motion blur. Input lag is also lower on the Q90T, but the Q80R has better black uniformity and out-of-the-box color accuracy.
The LG CX OLED is better than the Samsung Q80/Q80R QLED. The LG can individually turn off its pixels, so it's able to produce perfect blacks. It also has much wider viewing angles, a quicker response time, and better out-of-the-box color accuracy. The Samsung gets much brighter and it doesn't have permanent burn-in risk.
The Samsung Q80/Q80R QLED outperforms the Samsung Q70/Q70T QLED in almost every category. The Q80R looks and feels better-built, has local dimming, can get much brighter, especially with HDR content, has much better viewing angles, handles reflections much better, has much better motion handling, and has a wider color gamut. Its biggest disadvantage is that its contrast ratio isn't quite as high as the Q70T.
The Samsung Q80R is better than the Samsung Q7FN. The Q80R has a full array local dimming that significantly boosts dark room performance, and thanks to the 'Ultra Viewing Angle' technology the image remains accurate for wider angles. The Q80R can display judder-free movies from any source and also has lower input lag, which is great for playing video games. The Samsung Q7FN can handle reflections a little better, and this is great if your room has many lights. It also has a wider color gamut.
The Samsung Q80R is better than the Sony X900F. The Samsung Q80R has wider viewing angles thanks to the 'Ultra Viewing Angle' technology. The local dimming support is better on the Q80R, as is the overall dark room performance, thanks to the deep uniform blacks. The Samsung Q80R is a better choice for gamers, as it has a lower input lag and is packed with gaming features like FreeSync support. The Sony X900F has slightly crisper motion thanks to the faster response time.
For most people and uses, the Samsung Q80/Q80R QLED is a better TV than the Samsung Q900/Q900R 8k QLED. The Q80R has much better contrast, better gray uniformity, better reflection handling, and better black uniformity. The main advantage of the Q900R is that it has an 8k resolution panel, though at the time of writing, there isn't much 8k content available, and most of what you're watching will be upscaled to that resolution. Overall, while both TVs perform excellently for most uses, the Q80R likely represents better value for most people, unless having an 8k panel is crucially important to you.
The Samsung Q80/Q80R QLED is better overall than the TCL 8 Series 2019/Q825 QLED. While the TCL has a higher contrast ratio, the Samsung offers better performance overall, with wider viewing angles and better reflection handling, as well as VRR support, a faster response time, and a lower input lag.
The Samsung Q80/Q80R QLED TV is much better than the Samsung NU8000. The Q80 has a full array local dimming feature, which is great for dark room performance, whereas the NU8000 is edge-lit and its local dimming isn't good. The Q80 can also get significantly brighter, and has better viewing angles and better reflection handling.
The Samsung Q80/Q80R QLED is a slightly better TV than the Sony Z9F. The Q80 has better blacks, better black uniformity, slightly better motion handling, and an easier-to-use smart interface. On the other hand, the Sony is brighter, has better gray uniformity, and has a much better color gradient performance.
The Sony A8G OLED is a marginally better TV than the Samsung Q80/Q80R QLED. The OLED has a faster response time and has perfect blacks thanks to its OLED panel that turns each pixel on and off individually. On the other hand, the Samsung can get much brighter, has a wider color gamut, much lower input lag, and is more accurate out-of-the-box. The OLED also has the risk of permanent burn-in, though this is unlikely with regular use.
The two TVs have different panels, but the Samsung Q80R has the 'Ultra Viewing Angle' technology that allows it to display wider viewing angles than typical VA panel TVs at the expense of lower contrast ratio. For most uses, the Samsung Q80R is a much better TV than the LG SM9500. The Q80R has excellent dark room performance with deep blacks thanks to its effective local dimming support. Also, the image on the Q80R remains accurate for fairly large angles. The LG SM9500 still has wider viewing angles, so it's more suitable if viewing angles are the main concern. In most other cases, the Q80R is the better choice.
The Samsung Q80/Q80R QLED is a much better TV than the LG UM7300. The Q80R looks more premium, has much better contrast and higher peak brightness, resulting in more uniform blacks and better reflection handling. It also as much more accurate colors out-of-the-box, and a much wider color gamut, making it a better choice for HDR content. While the LG has slightly lower input lag, the Samsung has better motion handling.
The Samsung Q80/Q80R QLED is a much better TV than the LG SM9000. Thanks to its VA panel, the Q80 has much deeper blacks thank the SM9000, though this is at the expense of viewing angles, and the image on the LG will be much more accurate when viewed from an angle. Other than that, the Q80 also looks better out-of-the-box, can get much brighter, has better motion handling, and has a wider color gamut.
These are two different types of TVs, each with its advantages and disadvantages. The LG B8 is an OLED TV with perfect blacks and outstanding dark room performance, which is great for movies and HDR movies. The LG also has marginally wider viewing angles, which is great if you often watch TV from the side. As an OLED, the LG has an almost instantaneous response time that delivers very crisp motion. The Samsung Q80R is a QLED TV that can get brighter. It has a wider color gamut, better color volume, and is packed with gaming features like low input lag with motion interpolation and FreeSync support.
