The Samsung U7900F is an entry-level 4k TV released in 2025 as part of Samsung's Crystal UHD 4K lineup, sitting below the Samsung U8000F. It's a very basic TV, with a limited selection of inputs, a 60Hz refresh rate, and no local dimming. It's powered by Samsung's Crystal Processor 4K image processor, and runs a slightly toned-down version of Samsung's proprietary Tizen OS. We bought and tested the 65-inch version, but it's also available in 43, 50, 55, 58, 70, 75, and 85-inch models.
Our Verdict
The Samsung U7900F is a poor TV. It's best suited for watching shows in a light-controlled room. It's not bright enough to overcome glare, and it has sub-par black levels with no local dimming, so it doesn't look good in a dark room, either. It can't display a wide range of colors, but it has good accuracy in SDR out of the box. Gamers will appreciate its low input lag, ensuring a responsive gaming experience overall, but it has poor motion handling, and there's a lot of blur behind fast-moving objects. On the other hand, it has okay processing, so low-resolution and low-quality content looks okay.
Good accuracy in SDR out of the box.
Can't reduce the intensity of direct, mirror-like reflections.
Mediocre screen uniformity.
Not bright enough to overcome glare in a bright room.
Only two HDMI inputs, no optical audio port.
The Samsung U7900 is a poor choice for home theater usage. It doesn't look good in a dark room, as it has poor black levels and no local dimming, so the screen looks washed out in most scenes. It has okay processing, with good EOTF tracking in HDR, but it doesn't support Dolby Vision or advanced DTS audio formats. Finally, HDR adds almost nothing, as it can't display a wide range of colors, and it's not bright enough for small specular highlights to stand out at all.
Good accuracy in SDR out of the box.
Mediocre screen uniformity.
Very low brightness in HDR, most scenes are flat and dull.
No local dimming.
Only two HDMI inputs, no optical audio port.
The Samsung U7900 is a disappointing choice for a bright room. Although ambient light has very little impact on picture quality, it doesn't look good to start with, as it has poor black levels, sub-par colors, and low peak brightness. It can't overcome glare, so both direct and indirect reflections are distracting.
Ambient light has very little impact on black levels or color saturation.
Can't reduce the intensity of direct, mirror-like reflections.
Not bright enough to overcome glare in a bright room.
The Samsung U7900 is a sub-par TV for watching sports. It doesn't look good in a bright room, so it's not a good choice for daytime viewing. The image also degrades rapidly when viewed at an angle, making it unsuitable for a wide seating arrangement or for watch parties. Uniform areas like the playing field are patchy and don't look good, and it has a slow response time, so fast-paced action is very blurry.
Can't reduce the intensity of direct, mirror-like reflections.
Mediocre screen uniformity.
Fast motion is very blurry.
The Samsung U7900 TV is a poor choice for gaming. It has low input lag in all supported modes, ensuring a somewhat responsive gaming experience. It also supports VRR, but because it has a low maximum refresh rate, this feature isn't very effective, and there's still tearing. Switching to the low input lag Game Mode has no negative impact on picture quality, but it doesn't look good anyway, with poor black levels, low peak brightness, and sub-par colors.
Game Mode has no impact on picture quality.
Very low input lag.
Fast motion is very blurry.
Narrow VRR range.
Limited to a 60Hz refresh rate.
Only two HDMI inputs, no optical audio port.
The peak brightness of the Samsung U7900F is bad. It's not bright enough to overcome any direct reflections, so it's only suitable for use in a light-controlled room. It's not bright enough to deliver an impactful HDR experience, either, as bright specular highlights fall flat and don't stand out at all.
Very low brightness in HDR, most scenes are flat and dull.
Not bright enough to overcome glare in a bright room.
The Samsung U7900F has poor black levels. It has a decent native contrast ratio but no local dimming, so blacks are raised and look washed out. It has great black uniformity, though, with very little backlight bleed and limited clouding in dark scenes.
Great black uniformity.
No local dimming.
The Samsung U7900F has sub-par colors. It's fine for watching most SDR content, with good accuracy out of the box, but it displays a limited range of colors even in that mode. HDR adds very little to this TV as it can't display the wider HDR color spaces.
Good accuracy in SDR out of the box.
Colors are dull and muted.
Very low color volume.
Note: We're in the process of improving our tests related to image processing, but this score should give you a general idea of how a TV performs overall with its image processing capabilities.
The Samsung U7900F has okay processing capabilities. It has okay upscaling, with no noticeable over-sharpening or upscaling artifacts, and it does a passable job of smoothing out low-quality content. It also has good PQ EOTF tracking, so shadow details and low-level midtones are displayed at the correct brightness level in HDR. On the other hand, although it processes gradients properly, it can't display them well due to its limited color gamut.
Good EOTF tracking in dimmer scenes.
The Samsung U7900 has mediocre responsiveness in Game Mode. It has low input lag, so games feel responsive overall, but its slow response time results in poor motion clarity, and it has limited VRR support.
Game Mode has no impact on picture quality.

Popular TV Comparisons
The Samsung U7900F is an extremely basic TV with poor picture quality and very few extra features. It's a bit overpriced for the performance it delivers, and you're far better off buying a different model from competing brands, like the TCL QM5K or the Hisense QD6QF.
For more options, check out our recommendations for the best TVs under $500, the best 65-inch TVs, and the best TVs for gaming.
The Samsung U8000F is a slightly better TV than the Samsung U7900F, but the differences are minor. They perform the same for the most part, but the U8000F gets quite a bit brighter, so while still not great, it can handle a bit more glare in a bright room. The U8000F also has an additional HDMI port, so it's slightly more versatile.
The Samsung U7900F and the LG UA77 are both poor TVs, but they trade blows in a few different ways, and the best one depends on your viewing environment. The LG gets quite a bit brighter and handles reflections better, making it the safer choice for a moderately lit room. The Samsung has much better contrast, though, so it's the better choice for a dim or dark room.
The TCL Q77K and the Samsung U7900F are both sub-par TVs, but the TCL is slightly better overall and significantly better for gaming. The TCL gets a bit brighter, so it can overcome more glare in a moderately-lit room. The biggest difference is for gaming, where the TCL shines thanks to its much higher refresh rate and better VRR support, ensuring a nearly tear-free gaming experience with any source.
The Samsung Q7F 2025 and the Samsung U7900F are both sub-par TVs, but the Q7F is slightly better. The Q7F gets quite a bit brighter, so it can handle a bit more glare in a moderately-lit room, and HDR stands out slightly better. The Q7F also has higher native contrast, so blacks are deeper in dark scenes, but it's still not great. Finally, the Q7F has an additional HDMI port, making it slightly more versatile. The U8000F, on the other hand, supports VRR, but this adds very little as it's only effective across a very narrow refresh rate range.
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 are done with 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.
Test Results
The Samsung U7900 has bad peak brightness in HDR. It's not bright enough to bring out specular highlight details at all, and brighter scenes are flat and dull. There's no global dimming in HDR on this TV.
These measurements are in the Filmmaker Mode with 'HDR Tone Mapping' set to 'Static'. Below are the results with 'HDR Tone Mapping' set to 'Active', which increases the brightness of some scenes slightly, while not changing the actual peak brightness of the display.
- Hallway Lights: 196 cd/m²
- Yellow Skyscraper: 193 cd/m²
- Landscape Pool: 154 cd/m²
There's a very minor difference in peak brightness when you switch to the lowest-latency Game Mode, but it's not a noticeable difference.
This TV has poor peak brightness in SDR, and it's not bright enough to overcome glare when used in a bright room. It lacks a local dimming feature that can dim the screen by zone, but there's a global dimming feature, commonly called CE dimming, that dims the entire screen in very dark scenes.
The Samsung U7900F has poor contrast. The native contrast of the panel is decent, but since it lacks local dimming, this doesn't really matter. Blacks are raised and look washed out in most scenes. It performs a bit better in extremely dark scenes, though, as its global dimming feature dims the entire backlight to reduce black levels when most of the screen is dark.
There's no local dimming feature, so there are no lighting zones. This means there's no haloing around bright elements against a dark background or subtitles, but the entire image looks gray and washed out.
This TV doesn't have a local dimming feature, so it can't adjust the backlight of individual zones to brighten up highlights without impacting the rest of the image. This means that there are no distracting flickers or brightness changes as bright highlights move between dimming zones.
This TV has great black uniformity. Blacks are raised in dark scenes due to the TV's low contrast ratio, but they're fairly uniform, with no significant clouding or backlight bleed.
Unfortunately, this TV has poor color volume in SDR. It can't display the full range of colors that make up the BT.709 color space used by most SDR content, let alone much of the wider DCI-P3 or Rec.2020 color spaces used in HDR. There's also a noticeable drop in color volume at higher luminance levels, as colors simply aren't very bright.
| Volume ΔE³ | DCI-P3 Coverage |
BT.2020 Coverage |
|---|---|---|
| L10 | 82.21% | 56.46% |
| L20 | 81.45% | 55.27% |
| L30 | 79.22% | 53.56% |
| L40 | 75.91% | 52.73% |

This TV has poor color volume in HDR. It can't display a wide range of colors, and the colors it displays aren't very bright. It can't display dark saturated colors well, either, due to its low contrast ratio.
The Samsung U7900F has good SDR accuracy out of the box. The white balance is good, and the overall RGB balance is okay overall, but there's too much blue in brighter shades. Gamma tracking is okay on average, but shadow details are crushed, while bright highlights are too bright. Color accuracy is good, but blues and reds are oversaturated. Finally, the color temperature is very close to the target.
This TV has excellent accuracy after a full calibration. The white balance is fantastic, but shadow details are still crushed. Color accuracy is excellent, but reds and blues are still off. Calibrating it shifted the color temperature a bit, and it's not a bit too warm, but it's not noticeable.
See our full calibration settings.
Unfortunately, this TV has mediocre color accuracy in HDR out of the box. The white balance is okay, but the RGB balance is off, and blues are overrepresented in midtones and bright highlights. The color accuracy is poor, though, with noticeable mapping issues in every color, and the color temperature is noticeably cold.
The accuracy in HDR after calibration is good. Color accuracy didn't improve much, as it's largely limited by the range of colors the TV can display, but the white balance is much better. The color temperature is nearly perfect, and the RGB balance is great.
The Samsung U7900F has good PQ EOTF tracking with dim content and midtones, as it's limited by the peak brightness of the display. Near blacks are raised due to the TV's low contrast ratio, but shadow details are displayed close to the creator's intended brightness level. There's a slight roll off near the TV's peak brightness, which helps preserve some gradation in brighter scenes, but almost all bright content is darker than it should be.
Unfortunately, Samsung has removed HGIG from their 2025 and 2024 models. Their intention was to move it to the "Original" Game Genre setting, but it's not working properly. This means that most games won't be displayed at the correct brightness level.
This TV does a passable job of smoothing out low-quality content. Macro blocking and pixelization artifacts are still present when watching streaming content, but there's very little loss of fine detail. It's still a bit better than the step-up Samsung U8000F, which can't remove compression artifacts at all, despite using a similar processor.
This TV has alright upscaling. The image is noticeably soft, and small details like text can be hard to make out.
The Samsung U7900 has sub-par gradient handling in HDR. While there's very little banding in most shades, it's severely limited by its color gamut, so there's no noticeable gradation in saturated colors. This is especially noticeable in the 50% to 100% red bar, which shows no gradation at all as the TV reaches peak red saturation at the start of the bar.
The Samsung U7900F has low input lag in most supported modes, which helps it deliver a responsive gaming experience. Unlike higher end Samsung TVs, including the Samsung U8000F, this TV doesn't support motion interpolation in Game Mode.
Unfortunately, this TV doesn't support refresh rates above 60Hz with any resolution. Chroma 4:4:4 signals are displayed properly, which helps with clear text from a desktop PC.
This TV supports all three types of VRR, but it's not very effective. Due to its low maximum refresh rate, the refresh rate range isn't wide enough to work with Low Framerate Compensation (LFC), so you'll see tearing if your framerate drops below 48Hz.
Unfortunately, this TV has a slow response time at the maximum refresh rate of 60Hz, so motion is blurry in most scenes. Transitions in shadow details and bright scenes are quite a bit faster than midtones.
This TV doesn't support a 120Hz refresh rate.
Unfortunately, this TV has a slow response time at the maximum refresh rate of 60Hz, so motion is blurry in most scenes. Transitions in shadow details and bright scenes are quite a bit faster than midtones.
This TV is a 60Hz TV, so it only supports 4k @ 60Hz on the P55. It has Auto Low Latency Mode (ALLM), so it'll automatically switch to Game Mode when it detects a game in progress, giving you the lowest possible input lag.
This TV only supports 4k @ 60Hz Xbox Series consoles. It has Auto Low Latency Mode (ALLM), so it'll automatically switch to Game Mode when it detects a game being played, which gives you the lowest possible input lag for games. It doesn't support Dolby Vision.
Thanks to the relative slow response time on this TV, there's just a bit of stutter in slow panning shots when watching movies.
There's no micro judder on this TV.
The Samsung U7900F automatically removes judder from most 24p sources. Unfortunately, it can't remove judder from external 25p sources, or from 24p sources that send a 60p signal, like an older cable box.
This TV has a very slow cinematic response time. This helps reduce stutter in slow panning shots, but the image is very blurry in fast action scenes.
This TV uses pulse-width modulation (PWM) to dim its backlight, which introduces flicker that can bother people who are sensitive to it. It flickers at 480Hz in Movie mode at all Brightness settings, with an additional 60Hz blip. It flickers at 120Hz in all other picture modes.
This TV supports backlight strobing, more commonly known as black frame insertion (BFI). The feature is designed to improve the appearance of motion by strobing its backlight, but the pulse timing is off, creating a duplicate image.
This TV has an optional motion interpolation feature. It's okay in slow panning shots, but there are a lot of artifacts in busier scenes.
The direct reflection handling on this TV is sub-par. It does very little to reduce the intensity of bright, mirror-like reflections.
Ambient light has no noticeable impact on black levels.
The total amount of reflected light is good overall. Bright lights are reflected back like a mirror, and the screen coating spreads them out a bit, making them even more distracting.
The perceived color saturation in a bright room is mediocre. While ambient light has little impact on perceived color volume, it's low to begin with.
The viewing angle on this TV is mediocre. It's not well-suited for a wide seating arrangement as the image degrades rapidly when viewed from the sides. Colors shift at a slight angle, giving the TV a noticeable green tint before the image fades as you move further off center.
The Samsung U7900F has okay gray uniformity. The sides of the screen are significantly darker than the center, but there's relatively little dirty screen effect in the middle.
This TV uses a BGR subpixel layout. It doesn't affect picture quality but can cause issues with text clarity in some applications when using it as a PC monitor. The SPD shows that it doesn't use quantum dot technology or a KSF phosphor, which explains the limited color volume.
This TV has a very limited selection of inputs, with only 2 HDMI inputs. It also lacks an optical audio port, so you have to use ARC/eARC to connect it to an external soundbar or receiver.
This TV supports most Dolby Digital audio formats. Oddly, unlike other 2025 Samsung models, Dolby Digital Plus 7.1 passthrough works properly. Unfortunately, it doesn't support DTS formats, which is disappointing, as many Blu-rays use DTS for their lossless audio tracks.
The Samsung U7900F doesn't look too bad for a low-end TV. It has thin bezels on three sides, with a thicker bottom bezel that doesn't look too bad.
The two feet are made of plastic and are set at the ends of the TV, with no alternative mounting position. The feet only lift the TV about 2.8" above the table, so larger soundbars will block a portion of the screen.
The footprint of the 65-inch stand is 39.5" x 8.7".
The inputs are housed in a central electronics box. One of the HDMI inputs faces straight out the back of the TV, so if you're planning on wall-mounting it you'll need a 90° adapter for the HDMI cables. Unfortunately, there's nothing to help with cable management.
The Samsung U7900F has mediocre build quality. The back of the TV is made of cheap plastic and there's a lot of flex in the back panel.
The Samsung U7900 Series comes with the 2025 version of Samsung's proprietary Tizen OS but has a reduced feature set compared to more expensive models, so you don't get features like TV to Mobile or Ambient Mode+. The interface is a bit slow at times, but it's still easy to find content to watch.
Like most TVs, there are ads on the home screen. You can't disable them completely, although you can turn off targeted ads.
This TV has a mediocre frequency response. There's very little deep bass, but it has a well-balanced sound profile at moderate listening levels, and dialogue is clear.
