The Samsung S90D/S90DD (QD-OLED) is a high-end TV in Samsung's OLED lineup and only sits below the flagship Samsung S95D OLED. The TV features Samsung's new Neo Quantum 4k AI Gen 2 processor, designed to improve performance and deliver better overall picture quality than its predecessor. It has the same features as its predecessor, the Samsung S90C, but it adds a new one called Auto AI mode, which uses AI technology to automatically adjust the picture settings based on the genre of game it detects. The TV has 40W 2.1 channel speakers built-in, uses the 2024 Tizen OS, and is available in six sizes: 42-inch, 48-inch, 55-inch, 65-inch, 77-inch, and 83-inch. The 42-inch, 48-inch, and 83-inch models use WOLED panels.

It's important to note that Samsung's 2024 OLED lineup is confusing. They're releasing S90Ds with both WOLED and QD-OLED panels, and the type of panel you get varies by the TV's size and what region you're in. A QD-OLED panel's performance and overall picture quality is typically better than a traditional WOLED panel, so this decision will surely lead to some disappointed customers. Our review is based on the QD-OLED version of the TV. You can find more information on the S90D's different panel types here.

  7. Updated Mar 25, 2024: We've purchased the product and are waiting for it to arrive in our lab.

Differences Between Sizes And Variants

We bought and tested the 65-inch Samsung S90D/S90DD (QD-OLED), and these results are also valid for the 55-inch and 77-inch models that use QD-OLED panels. In North America, the 42-inch, 48-inch, and 83-inch models use a WOLED panel (EXZA), and the 55-inch, 65-inch, and 77-inch models use a QD-OLED panel (FXZA). Our results don't apply to any WOLED version of the TV.

Internationally, it's a bit more complicated. In Australia, for example, the model codes are different, and the 55-inch and 65-inch sizes that use QD-OLED panels end in 'WXXY,' whereas the 77-inch and 83-inch models that use WOLED panels end in 'EXXY.' These last four digits vary between different regions, but if the fourth last digit of the model code is an 'E,' the TV very likely uses a WOLED panel. 

The TV is also sold as the Samsung S90DD at warehouse stores like Costco and Sam's Club with a longer warranty. There's also a Canadian variant known as the Samsung S92D. The S90DD and the S92D offer the same features, picture quality, and processing capabilities but have more powerful speakers (60W vs. 40W on the S90D). In Canada, the last digit of the model code in all sizes and variants of the S90D ends with 'C,' but there's no difference in performance.

Compared To Other TVs

The Samsung S90D/S90DD (QD-OLED) is an exceptional TV and is one of the best OLEDs you can buy. It's a bit brighter than its predecessor, has less banding, and does a better job at smoothing out low-quality content, but it's also currently a lot more expensive. Unless you need the incremental upgrades it offers, you're better off buying the cheaper Samsung S90C OLED while it's still available.

For more options, check out our recommendations for the best OLED TVs, the best 4k TVs, and the best TVs for watching movies.

Samsung S90C OLED
55" 65" 77" 83"

The Samsung S90D/S90DD OLED is marginally better than the Samsung S90C OLED. The S90D is a bit brighter in HDR, so highlights in HDR content stand out a little bit more, and it has better color volume, so it can display very bright colors a bit better. The S90D also has slightly better processing, so there's less banding in colors, and it does a better job with smoothing out low-quality content.

LG C4 OLED
42" 48" 55" 65" 77" 83"

The Samsung S90D/S90DD OLED is mostly better than the LG C4 OLED. The Samsung gets brighter in HDR, so bright highlights stand out more on it, and it maintains its HDR brightness better while in 'Game Mode.' The Samsung TV also has a wider color gamut, better color volume, and better HDR gradient handling, so colors in HDR are more vibrant, lifelike, brighter, and have less banding. The Samsung has a wider viewing angle, and the image doesn't have a green tint that worsens as you move off-center, so it's the better choice for watching TV in a group setting. However, the LG supports Dolby Vision and DTS audio formats, so it's the better option for those looking to get the most out of their physical media.

LG G4 OLED
55" 65" 77" 83" 97"

The LG G4 OLED and the Samsung S90D/S90DD OLED are both amazing TVs, but there are some differences worth noting. The Samsung has a wider color gamut, so it can display more vibrant and lifelike colors, and it has better color volume, so it can display brighter colors. The S90D also has no noticeable banding in colors, while the LG does have some banding in certain colors. On the other hand, the LG has better low-quality content smoothing, so it's the better choice if you regularly watch DVDs or low-quality streams. The LG also supports both Dolby Vision and DTS audio formats, which is great if you're looking to get the most out of your 4k Blu-ray collection. On top of that, the LG has better SDR brightness, so it overcomes more glare in a bright room.

LG C3 OLED
42" 48" 55" 65" 77" 83"

The Samsung S90D/S90DD OLED is mostly better than the LG C3 OLED. The Samsung has a wider color gamut, so colors are more accurate and lifelike, and it can display colors brighter due to its better color volume. The Samsung also has better HDR brightness, so bright highlights stand out more in HDR content. However, the LG is brighter in SDR, so it overcomes more glare in a bright room. The LG also has better low-quality content smoothing, so it's the better option if you regularly watch DVDs or lower-quality streams, and if you collect Blu-rays, the LG is the better choice due to its Dolby Vision and DTS audio support. 

Samsung S95D OLED
55" 65" 77"

The Samsung S90D/S90DD OLED and the Samsung S95D OLED are very similar TVs, but there are some differences. The S90D has less banding in colors due to its better HDR gradient handling and better pre-calibration SDR accuracy. On the other hand, the S95D has better PQ EOTF tracking and slightly better color volume, so HDR content is closer to the content creator's intent, and the TV can display colors a bit brighter. The S95D also comes with Samsung's Slim One Connect Box, so it's more versatile if you need quicker access to its ports, and its matte screen finish does an amazing job at essentially eliminating reflections caused by glare, albeit at the expense of picture quality.

Samsung S95C OLED
55" 65" 77"

The Samsung S95C OLED and the Samsung S90D/S90DD OLED are very similar, but there are some minor differences. The S90D has better processing, so there's less banding in colors and fewer artifacts present in low-quality content, and it does a slightly better job at upscaling low-resolution content. The S90D is also a tad brighter in HDR, so highlights pop a little bit more on it. However, the S95C comes with Samsung's Slim One Connect Box, so if you need a versatile way to plug in your devices, it's the better option.

LG G3 OLED
55" 65" 77" 83"

The LG G3 OLED and the Samsung S90D/S90DD OLED are similar TVs, each with their own strengths. The LG gets brighter in SDR, so it overcomes more glare in a bright room. The LG also does a better job at smoothing out low-quality content, so if you regularly watch DVDs or lower-quality streams, it's the better option for that. If you're a fan of physical media, the LG is the better option due to its Dolby Vision and DTS audio support. On the other hand, the Samsung has better HDR brightness, so highlights in HDR content pop a little more on it, and its better color volume means it can display brighter colors. If you're a PC gamer, the Samsung supports up to 4k @ 144Hz, so it's the better TV to pair with PCs that have high-end graphics cards.

Sony A95L OLED
55" 65" 77"

The Sony A95L OLED and the Samsung S90D/S90DD OLED are very similar TVs. The Sony gets brighter in SDR, so it overcomes more glare in a bright room. The Sony also has better processing for low-quality and low-resolution content, so lower-quality streams or DVDs look better on it. However, the Samsung has less banding in colors. When it comes to gaming, the Samsung has lower input lag for a more responsive experience, and it supports up to 4k @ 144Hz for PC gamers with high-end graphics cards.

Samsung QN90D/QN90DD QLED
43" 50" 55" 65" 75" 85" 98"

The Samsung S90D/S90DD OLED (QD-OLED) is better than the Samsung QN90D/QN90DD QLED. The S90D displays deeper blacks in a dark room due to its nearly infinite contrast ratio, and there's no blooming. The S90D also has a much wider viewing angle, so no matter where you or your friends sit, you'll see a consistent image. The S90D really shines when it comes to colors, and its much wider color gamut displays incredibly vibrant and lifelike colors with no noticeable banding in color gradients. The S90D also has a faster response time, so there's no noticeable blur behind quick motion. The QN90D is the brighter TV overall, so it fights more glare in very bright rooms, but the S90D is also no slouch in that regard.

Samsung QN85D/QN85DD QLED
55" 65" 75" 85"

The Samsung S90D/S90DD OLED is better than the Samsung QN85D/QN85DD QLED, but they use different panel technologies. The S90D is an OLED, so it has perfect contrast, making it far superior to the QN85D when viewed in a dark room. The S90D is also a bit brighter than the QN85D in HDR, although the latter has a clear edge in brightness in SDR content. The S90D also has far better reflection handling and a significantly wider viewing angle, so ultimately, it's just in a different league than the QN85D.

Build Quality

The Samsung S90D has good build quality overall. There's some wobble on the stand when the TV is pushed forward or backward, but it quickly settles and won't cause any problems. There is a bit of flexing on the plastic central housing on the back, but this is normal and isn't concerning.

What's more concerning is the misaligned HDMI ports on our unit that makes two of the HDMI ports unusable. Our panel is also slightly bent and bows outwards in the center, although it's hard to notice when watching the TV head-on. These issues are likely isolated to our unit, but it's a knock against the TV if these issues with build quality are more widespread.

Blooming

Since OLEDs don't use local dimming and instead have individual pixels that can be lit up to their maximum brightness next to pixels that are turned off, there's no blooming when bright elements are surrounded by deep blacks.

The Samsung S90D/S90DD has excellent HDR brightness. It gets bright enough for highlights to really stand out and delivers an impactful HDR experience. Unfortunately, large bright scenes are significantly dimmer than smaller specular highlights due to the TV's aggressive Automatic Brightness Limiter (ABL).

The TV's Automatic Static Brightness Limiter (ASBL) is surprisingly aggressive with the sustained 10% window, so small bright highlights are dimmed considerably when they're on screen for more than a few minutes. This behavior is not noticeable with real content.

The Samsung S90D has fantastic PQ EOTF tracking, so content is mostly displayed at the correct brightness level. Darker shadows and midtones are a bit brighter than intended by the content creator, but the TV follows the curve closely until it reaches the TV's maximum brightness. With content mastered in 600 or 1000 nits, there is a very slight roll-off to preserve some detail in highlights. With content mastered at 4000 nits, there is a more gradual roll-off to preserve detail in very bright highlights.

The Samsung S90D/S90DD has good SDR peak brightness, and it's bright enough to overcome glare in a bright room. Unfortunately, the panel's brightness is dimmed considerably by its Automatic Brightness Limiter (ABL), so large bright scenes are significantly dimmed. It's the most distracting when watching sports like hockey with bright playing surfaces.

These measurements are after calibration with the following settings:

  • Picture Mode: Movie

The TV has an exceptionally wide color gamut. It displays the full range of colors in the DCI-P3 color space that's often used in HDR content, and colors are very accurate overall. Its coverage of the wider Rec. 2020 color space that's increasing in popularity isn't as good, but it's still excellent, with only some highly saturated colors being off from what they should be.

New to Samsung TVs in 2024 is the 'Color Booster' feature. This setting oversaturates colors but does a surprisingly good job at maintaining accuracy within the DCI-P3 and Rec. 2020 color spaces. Colors are still more accurate with the setting turned off, but it works well if you want more saturated colors without losing too much accuracy.

Upscaling: Sharpness Processing

The Samsung S90D/S90DD does a very good job at upscaling low-resolution content like DVDs or lower resolution streams. Details are clear enough, but small hard-coded text is hard to make out.

Sharpness processing was calibrated with no over-sharpening for low-resolution content, with the following settings:

  • Sharpness: 5

Picture Quality
Pixels
Subpixel Layout
Triangular RGB
Type OLED
Sub-Type
QD-OLED

The Samsung S90D (QD-OLED) uses a unique subpixel structure. Instead of having all three subpixels in a row, each pixel forms a triangle, with the larger green subpixel at the top. This leads to color fringing, which is noticeable when displaying any content with horizontal lines, and it's especially bad when you use the TV as a PC monitor. For example, on a bright window on a Windows PC, you might notice a green fringe at the top since that's where the green subpixel is.

Similarly, you can notice a purple fringe at the bottom of bright windows, as that's where the red and blue subpixels are. Furthermore, with this subpixel arrangement, text has just okay clarity on a PC, as Windows ClearType settings aren't designed for this subpixel structure and can't correct for it.

In North America, the 42-inch, 48-inch, and 83-inch sizes use a WOLED panel, which has a different subpixel structure than the other sizes of this TV. Internationally, the type of panel used varies by size and region. You can find more information on this here.

The Samsung S90D has a nearly-instantaneous response time, which results in incredibly clear motion with almost no blur behind fast-moving objects. Due to the sample-and-hold nature of OLED technology, there's still some noticeable persistence blur when gaming at 60Hz, but it's hardly noticeable at higher refresh rates.

The Samsung S90D/S90DD supports all three types of variable refresh rate (VRR) technology to reduce screen tearing. It works well across a wide refresh rate range and supports sources with Low-Frame-Compensation (LFC), which ensures your games remain nearly tear-free even when your framerate drops very low.

Unfortunately, there is an issue when using NVIDIA graphics cards that effects frame rates above 120 fps. The TV essentially duplicates parts at the bottom of the screen.

The Samsung S90D supports most common resolutions up to 4k @ 144Hz. Chroma 4:4:4 signals are displayed properly with all supported resolutions when the TV's input label is set to 'PC', which is important for text clarity. Unfortunately, even though it can display chroma 4:4:4 properly, text from a PC isn't clear due to the unusual subpixel structure (see the Pixels section of the review for more on this issue).

Unfortunately, the TV has inconsistent issues with displaying 1440p. 1440p @ 60Hz works without issue, but when trying to display 1440p @ 120Hz and 1440p @ 144Hz with scaling disabled on both NVIDIA and AMD GPUs, the TV only displays a cropped window, so the TV isn't doing any upscaling. Strangely enough, this behavior is intermittent, and sometimes 1440p @ 120Hz and 1440p @ 144Hz work fine. There are also no issues with 1440p @ 120Hz when connected to a PS5 or Xbox Series X, which makes the issue even harder to identify.

This allows you to take full advantage of multiple high-bandwidth devices, like if you own both current-gen consoles and a high-end gaming PC. Unfortunately, Samsung still doesn't support Dolby Vision and supports HDR10+ instead, which is similar but not as widely supported. The TV also has variable analog audio out, so you can change the volume of any plugged-in analog devices, like headphones, using the TV's remote.

Unlike the Samsung S90C OLED, the S90D doesn't support ATSC 3.0 for 4k over-the-air, as Samsung has dropped that feature on their 2024 4k models.
