The Samsung 77S90H OLED is a midrange OLED TV released in Samsung's 2026 TV lineup, sitting below the flagship Samsung S95H OLED and above the Samsung S85H OLED. The TV has a matte screen coating that helps cut glare when you're watching TV during the day. It's powered by Samsung's NQ4 AI Gen3 Processor and runs the 2026 version of their proprietary Tizen OS, which has a massive selection of streaming apps and games, but like any Samsung TV, it doesn't support Dolby Vision. It has four HDMI 2.1 ports capable of 4k @ 165Hz and supports VRR. This review is for the 77-inch model specifically, which uses an RGB Tandem panel, that's advertised to offer brighter, more vibrant colors than the other sizes, but it's also available in 42, 48, 55, 65, and 83-inch sizes. We bought and tested the 65-inch model in a separate review.
Our Verdict
The Samsung 77S90H is an excellent TV that fits in just about anywhere. It looks amazing in a bright room thanks to its matte coating and high peak brightness. Of course, like all OLEDs, it delivers a stellar dark room experience, with perfect blacks and no trace of haloing around bright areas. It's also fantastic for gaming or watching sports, as it delivers incredibly crisp motion with no blur behind fast-moving objects. It also has a wide viewing angle that makes it suitable for just about any room, even if you have a very wide seating area or don't like to be glued to one spot directly in front of the screen.

Differences Between Sizes And Variants
We bought and tested the 77-inch Samsung S90H, and these results are valid for this size and the 48-inch model. The 42-inch model likely isn't as bright as the larger sizes, and the 55-, 65-, and 83-inch models use a different type of panel that's less colorful. We also bought and tested the 65-inch model and reviewed it separately.
Unlike previous versions of this TV, there are no sizes that use a QD-OLED panel in North America. However, Samsung is still using QD-OLED panels in certain regions, depending on the size of the TV. Our results aren't valid for the QD-OLED version of this TV.
The TV is also sold with a slightly different model code at warehouse stores like Costco and Sam's Club, and comes with an extended warranty.

Popular TV Comparisons
The Samsung 77S90H is an excellent TV. The inclusion of an RGB Tandem panel of this size significantly improves its overall performance, and thanks to its higher peak brightness and more vibrant colors, it delivers a better overall experience than the other sizes. This size specifically competes primarily against the LG C6H OLED, which uses the same panel, but the addition of a matte anti-reflective coating makes it a better choice for bright room viewing. It still falls slightly short of higher-end models with higher peak brightness, though, like the LG G6 OLED and the more premium Samsung S95H OLED.
For more options, check out our picks for the best 75-77 inch TVs, the best OLED TVs, and the best gaming TVs.
The LG C6H OLED and the Samsung 77S90H OLED are extremely similar TVs, as they share the same panel, but there are a few notable differences between them. The LG has better processing, so it looks better if you're watching a lot of streaming content or other low-quality sources. The LG is also brighter with most real content, mainly due to differences in the way the two TVs process images. On the other hand, the Samsung has better reflection handling, and is the better choice if you have a lot of windows or lights facing the screen.
The Samsung 77S90H OLED is better than the other sizes of the Samsung S90H OLED. The 77-inch version specifically uses a different type of OLED panel, which delivers much brighter, more vibrant colors. Although it still relies on a white subpixel, bright colors aren't nearly as washed out in light scenes, so most content, especially in HDR, is more colorful. Other than that, though, these are essentially the same TV.
The LG G6 OLED is better than the Samsung 77S90H OLED. Although color vibrancy is very similar between them, the LG is much brighter overall, so bright details in movies and shows stand out better. Very bright content, like sports and outdoor scenes in movies, is also significantly brighter on the LG, resulting in a more vibrant experience overall. The LG also has better image processing, which is especially noticeable if you watch a lot of streaming content or other low-quality sources.
The Samsung S95H OLED delivers better picture quality than the Samsung 77S90H OLED, but there are a few downsides to it. The S95H gets a lot brighter than the 77S90H, so small details in movies stand out a lot better, and bright content like sports is much more vibrant. The 77S90H, on the other hand, maintains contrast better in a bright room. The best one ultimately depends on what you value most: brightness or contrast. If you're watching TV in a moderately-lit room, the extra brightness of the S95H isn't as necessary, so the 77S90H becomes the better choice.
We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests use specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.

The Samsung 77S90H has a nearly infinite contrast ratio, giving it perfect contrast. Due to OLED's self-lit pixels, it displays bright highlights next to perfect inky blacks, making it very impressive in a dark room.
for pictures & test results
Since OLEDs don't use lighting zones and instead have individual pixels that can be lit up to their maximum brightness next to pixels that are turned off, there's no haloing when bright elements are surrounded by deep blacks.
for videos & test results
This TV is an OLED without a backlight, so its self-lit pixels give it the same performance as a TV with perfect local dimming and no zone transitions. We still film the zone transition video so you can see how it compares to an option with local dimming.

The Samsung 77S90H has fantastic PQ EOTF tracking. While most content deviates slightly from the intended brightness level, it's very minor and most people won't notice it. Content mastered at 600 and 1,000 nits cuts off sharply at the TV's peak brightness, so there's no loss of fine details or brightness. There's a slightly more gradual rolloff with content mastered at 4000 nits, which helps to retain details in very bright highlights.

This TV has good gradient handling. There's some very subtle banding in some gradients, but it's hard to notice in real content. It struggles to display gradients in very dark grays, though, likely due to its gamma tracking crushing shadow details a bit.
The Samsung 77S90H has extremely low input lag, as long as its in Game Mode. It offers a low latency motion interpolation mode, which allows you to improve motion smoothness on older consoles that are locked to a low frame rate without adding too much latency.
The TV supports all common resolutions up to 4k @ 165Hz, and it supports chroma 4:4:4, which helps with text clarity from a PC.
The TV supports FreeSync, HDMI Forum VRR, and G-SYNC, ensuring a nearly tear-free gaming experience from any VRR-enabled source. It works well across the TV's entire refresh rate range and supports sources with Low Framerate Compensation (LFC), which ensures your games remain nearly tear-free even when your frame rate drops very low.

The TV's CAD at 120Hz is outstanding. It displays fast-moving objects without noticeable blur, so fast motion is clear. There's more overshoot when transitioning from a darker shade to a brighter one than there is at 165Hz, but it's still very minor, and you won't notice any inverse ghosting because of it.
for pictures & test results
The TV is fully compatible with everything the PS5 and PS5 Pro have to offer, like 1440p @ 120Hz and 4k @ 120Hz, as well as VRR to reduce tearing. It also supports Auto Low Latency Mode, so you don't have to worry about switching to Game Mode to get the lowest input lag.

The TV has a nearly instantaneous response time, resulting in incredibly clear motion with almost no blur behind fast-moving objects when watching content. There's some overshoot in near-black transitions, but it's hard to notice. Due to the sample-and-hold nature of OLED technology, there's still some persistence blur at 60Hz, but it's not very noticeable when watching movies or shows.

Unlike the other sizes of the Samsung S90H, the Samsung 77S90H uses a Primary RGB Tandem panel, with much better color separation and stronger peaks than previous generations of WOLED panels. Note that despite the name, this is still a WOLED panel, its just the structure of the light emitting layers that's different from other WOLED panels. It still relies on a white subpixel for extra brightness.
It has a restructured subpixel layout, and the new RGWB is a bit better for text clarity from a PC. It's not perfect, though, as ClearType on Windows isn't well optimized to non-RGB subpixel layouts.
