The Hisense U7K is a lower mid-range 4k TV released in 2023. It sits between the Hisense U6/U6K and the Hisense U8/U8K in the company's 2023 ULED lineup and replaces the Hisense U7H. Compared to its predecessor, the U7K offers more local dimming zones and two HDMI 2.1 bandwidth ports that can do up to 4k @ 144Hz. It still has a full suite of gaming features, like variable refresh rate support and Hisense's Game Mode Pro gaming interface. It's also compatible with Dolby Vision HDR and HDR10+, is certified as IMAX Enhanced, and supports DTS and Dolby advanced audio formats. It has Google TV's user-friendly interface, which is easy to use, and has a great selection of streaming apps. It comes in four sizes: 55, 65, 75, and 85 inches.
Our Verdict
The Hisense U7K is a great TV overall. It gets bright in both HDR and SDR and has fantastic reflection handling, so it's stellar in any bright room setting. Its contrast is amazing, with outstanding black uniformity, so it also looks amazing in dark rooms when watching HDR movies and games. Plus, it has very good image processing and supports advanced audio and video formats, making it a great choice for home entertainment.

Differences Between Sizes And Variants
We tested the 65-inch Hisense U7K, and the results are also valid for the 55, 75, and 85-inch models. It's called the Hisense U75K at Costco, but it's the same as the regular U7K, except that it comes with a three-year warranty. In Canada, it's known as the Hisense U78KM, and it performs the same. There are similar international models, like the U7KAU in Australia, but these models perform differently from the North American U7K, so our results aren't valid for those models.

The Hisense U7K and the Hisense U7N are similar, but the U7N is a bit better in several ways. The U7N is brighter overall, so it handles more glare in a bright room when watching SDR content, and highlights in HDR content stand out more. The U7N has better contrast thanks to its more effective local dimming feature, so blacks are deeper on it. The U7N also has much better PQ EOTF tracking, so it's more accurate with HDR content. On the other hand, the U7K has much better pre-calibration SDR accuracy, so it's better for those who care most about color accuracy without needing calibration.
The Hisense U7K is better than the TCL Q750G. The TCL has better contrast than the Hisense, so it looks better in dark rooms. However, the Hisense is more colorful overall, is much more color-accurate pre-calibration, and has much better reflection handling. The Hisense also has a more functional VRR feature, as the TCL's response time fluctuates heavily as its refresh rate goes up and down, so the Hisense is also the better overall gaming TV.
The Hisense U7K and the TCL QM751G are closely matched. The TCL offers a more impactful viewing experience overall due to its better contrast and brightness, although the Hisense looks about as good in very bright rooms due to its much better reflection handling. The Hisense TV is, however, vastly more accurate pre-calibration than the TCL is; if you care about color accuracy yet aren't interested in having your TV calibrated, then the Hisense is for you.
The Hisense U7K and Hisense U8K are similar: they have the same feature set, but the U8K is a higher-tier TV, so it has better overall performance. The U8K gets brighter than the U7K, and this also gives it a higher color volume: colors are brighter and pop more on the more expensive model. It also has a more powerful local dimming feature, giving it better contrast in dark rooms. The U7K does have a better response time than the U8K, which is good for gamers or sports fans.
The Hisense U7K is essentially a better version of the Hisense U6K. The U7K has better contrast and black uniformity, so blacks are deeper when viewed in a dark room. Its better SDR brightness makes it better suited for a bright room since it can overcome more glare, and its better HDR brightness makes highlights pop more in HDR content. The U7K also has a quicker response time for less blur behind quick-moving objects and is the better choice to pair with modern gaming consoles due to its HDMI 2.1 bandwidth for 4k @ 120Hz and its more functional VRR feature.
The Hisense U7K is a noticeable improvement from the Hisense U7H. The U7K has better contrast with a better local dimming feature, so it looks better in dark rooms. While the U7K is about as bright as the older model, it has much better reflection handling and looks better in bright rooms. Its pre-calibration color accuracy is also vastly better than the U7H. The U7K also has a much better response time and much improved low-quality content smoothing. It's just a better TV all-around.
The Hisense U7K is much better than the Vizio Quantum Pro QLED. The Hisense has much higher contrast, resulting in deeper blacks and less blooming around bright highlights in dark scenes. The Hisense also has better image processing and handles low-quality or low-resolution content better, resulting in less noticeable macro-blocking and pixelization. Finally, the Hisense has much better smart features, with a significantly wider selection of streaming apps and a smoother user experience overall.
The LG C4 OLED is better than the Hisense U7K in almost every way, although the Hisense is a bit brighter than the LG in SDR content, and while the LG is a bit brighter in most HDR content, the Hisense does maintain its HDR brightness much better than the LG does when in their respective Game Modes. The Hisense also supports both HDR10+ and Dolby Vision, while the C4 only supports Dolby Vision. Still, these are slight advantages, as otherwise, the LG is much better than the Hisense in everything else: much better contrast, vastly superior viewing angle, better image processing, and is much better for gamers due to its near-instant response time and four full HDMI 2.1 ports with up to 4k @ 144Hz support, while the Hisense is limited to two 4k @ 144Hz HDMI ports.
The Sony X90L/X90CL and Hisense U7K are similar TVs, with the Hisense having a slight edge overall. The Sony is the slightly brighter TV in HDR and is noticeably brighter in SDR. However, the Hisense compensates for it by having superior reflection handling, making it a bit better for bright room viewing. The Hisense also looks better in dark rooms due to its slightly better contrast and vastly superior black uniformity. Unfortunately, the Sony TV is less interesting for gamers due to its higher input lag, and two HDMI 2.1 ports are capped at 4k @ 120Hz. The Hisense also has only two HDMI 2.1 ports, but they're both capable of 4k @ 144Hz. Plus, the Sony's eARC port is one of its HDMI 2.1 ports, so you lose one of them when a soundbar is connected, while the Hisense's eARC port is one of its HDMI 2.0 ports.
The Samsung QN90C and the Hisense U7K are similar TVs, although the Samsung has a slight edge over the Hisense. The Samsung gets brighter in HDR and SDR and has a better local dimming solution than the Hisense, giving it better contrast with less blooming. The Samsung also follows the content creator's intent more closely in HDR than the Hisense does. The Samsung has a wider viewing angle than the Hisense, so it's the better TV when hosting large parties, as the image fades much less when viewed from the sides. The Hisense does have better image processing than the Samsung, especially when watching low-bitrate content from streaming apps, and it also supports DTS audio formats and Dolby Vision HDR, both of which the Samsung doesn't have.
The Hisense U7K is much better than the Samsung Q60D. The U7K has a wider color gamut and better color volume for more vibrant, lifelike, and brighter colors. The U7K also has much better contrast due to its excellent local dimming and much better HDR brightness, so HDR content is much more impactful on it. Finally, the U7K has HDMI 2.1 bandwidth for up 4k @ 120Hz with VRR, so it's the better option for gamers with modern consoles.
The Hisense U7K is vastly superior to the LG QNED80 2023. The LG does have a much wider viewing angle than the Hisense, but otherwise, it's outperformed in every facet. In particular, the LG has a terrible contrast ratio with a truly poor local dimming solution, so it can't compete with the Hisense in a dark room. In bright rooms, the Hisense is brighter in HDR and SDR and has much better reflection handling. Finally, the Hisense is also better for gamers due to its slightly faster response time and two 4k @ 144Hz ports, while the LG is limited to 4k @ 120Hz on two of its ports.
The Hisense U7K is much better than the Samsung DU8000. The Hisense has much deeper blacks due to its local dimming feature, so it's better suited for watching content in a dark room. The U7K also has better color volume and a wider color gamut, so colors are more vibrant and lifelike on it, and its better overall brightness delivers highlights that pop in HDR and gives it the ability to overcome glare while watching SDR content in a bright room. The Hisense also has HDMI 2.1 bandwidth and VRR support, and it supports up to 4k @ 144Hz, so it's the better option for gamers.
The TCL QM850G and Hisense U7K are closely matched TVs, each with their strengths, although the TCL is just a bit better overall. The TCL is a performance standout: it gets much brighter than the Hisense and has better color volume, so bright highlights and colors look very impressive. The TCL also has deeper contrast than the Hisense, which is helped by a very good local dimming solution. However, the Hisense is much more color-accurate than the TCL pre-calibration and has slightly better upscaling capabilities. The Hisense also has a more functional VRR feature, as the TCL's response time fluctuates heavily as its refresh rate goes up and down.
The LG C3 OLED is better than the Hisense U7K. The Hisense is a bit brighter than the LG in HDR Game Mode but not in HDR outside of Game Mode. The Hisense is also a bit brighter in SDR, but otherwise, the LG C3 is better in every other facet; its contrast is far superior, so it looks superior when watching movies in a dark room, and it is the most accurate TV of the two in HDR and SDR. It also has four full HDMI 2.1 ports with 4k @ 120Hz support, while the Hisense is limited to two HDMI 2.1 ports, although they're both capable of up to 4k @ 144Hz. The LG also has a much wider viewing angle, so it's better when your friends are watching the TV in a wide seating arrangement. Finally, the LG has better image processing and is better for gamers due to its near-instant response time.
The Hisense U7K is significantly better than the LG QNED80 2022. The Hisense looks much better in a dark room thanks to its higher native contrast ratio and highly effective local dimming feature. The Hisense gets significantly brighter, especially when displaying HDR content, and HDR looks much better overall.
The Hisense U7K is better than the Sony X85K. The Hisense has a good local dimming solution, while the Sony doesn't, giving the Hisense much better contrast overall. Plus, the Hisense is brighter than the Sony in HDR, so content on the Hisense pops noticeably more than on the Sony, especially in dark rooms, but it's also better in bright rooms due to its better reflection handling. The Hisense also has better image processing and is better for gamers with its 4k @ 144Hz support on two ports, while the Sony is limited to 4k @ 120Hz, also on two ports.
The Hisense U7K is better than the Samsung CU7000/CU7000D. The Hisense has much deeper blacks thanks to its better black uniformity and local dimming feature, so it’s better for use in a dark room. The Hisense gets much brighter in HDR, supports a wider color gamut, and has better color volume, so colors are more vibrant and lifelike, and highlights pop a lot more than on the Samsung. The Hisense also gets much brighter in SDR, so it overcomes glare better in a bright room. Finally, the Hisense is much better for gaming as it has HDMI 2.1 bandwidth, supports VRR, and has up to 4k @ 144Hz support.
The Hisense U7K is vastly superior to the Sony X80K/X80CK. The Sony has only one advantage over the Hisense: a wider viewing angle, making it the better choice for wide seating arrangements as its image stays consistent when viewed from the sides. The Hisense is better in all other aspects: it looks much better in dark rooms due to its superior contrast, looks better in bright rooms due to its higher peak brightness in SDR and HDR, has vastly better reflection handling, and has much better image processing. The Hisense is also better for gamers due to its 4k @ 144Hz capabilities, faster response time, and full VRR support. Finally, the Hisense is much more colorful.

Ultimately, the Hisense TV has the edge over the Samsung model in every objective facet.
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
From the front, the TV has a premium design that looks great. It has thin bezels on three sides, with a thicker, but still thin, bottom bezel. The feet are slim and don't take up much space. From the back, the TV has visible screws around its border, which look a bit cheap overall.
The TV comes with a pair of adjustable metallic feet that support it well, although there's still some wobble front to back.
Footprint of the 65-inch stand in the wide position: 46.1" x 12.3". In the narrow position, the 65-inch stand has a footprint of 27.6" x 12.3". In either position, the feet lift the TV about 3.3" above the table, so most soundbars fit in front without blocking the screen. Some longer soundbars don't fit between the feet when they're set in the narrow position.
The back has a flat metallic top part and a thicker plastic housing on the bottom half. There's a built-in subwoofer on the bottom section. Most of the inputs are side-facing and aren't set into the TV, so they're easy to access unless you have the TV mounted flush against the wall. There are clips built into the feet to help with cable management.
The TV has decent build quality. There's a bit of flex in the plastic portion of the back, but this isn't uncommon and won't cause any issues. The feet are sturdy and support the TV well, but there's some wobble front to back. More worrisome, it creaks when it wobbles, which is slightly concerning. Our unit also has 10 dead pixels, or possible dirt stuck under the panel, around the top of the screen—they aren't visible from a normal viewing distance, but it speaks to less than stellar quality control.
The Hisense U75K Series has a fantastic contrast ratio with local dimming enabled, leading to deep blacks in a dark room, even when bright highlights are shown on the screen. With local dimming disabled, the TV's contrast ratio is good, but blacks are raised and appear washed out when bright highlights are present. If you want a similar TV with even better contrast, check out the Sharp AQUOS XLED FV1.
The Hisense U7K has decent blooming performance. There's some visible blooming around bright highlights or in dark areas when they're next to brighter ones.
Overall, the TV's processing keeps up well with fast-moving objects. Still, the leading edge of bright, moving objects is noticeably dimmer, and fast-moving objects leave a visible trail.
Switching to Game Mode doesn't result in any noticeable difference in dark scene performance.
The Hisense U7K has very good peak brightness in HDR. Bright highlights stand out well, delivering an impactful HDR experience. If you'd prefer a brighter TV, check out the TCL QM7/QM751G QLED instead.
These measurements are after calibrating the HDR white point with the following settings:
- HDR Picture Mode: HDR Theater
- Brightness: 100
- Gamma: ST2084
- Local Dimming: High
- Color Temperature: Warm 1
- Dynamic Tone Mapping: Off
If you want better HDR brightness, check out the newer Hisense U7N [U7, U75N].
The TV's HDR brightness in Game Mode is very good. There's no noticeable difference in peak brightness from 'HDR Theater' mode.
These measurements are after calibrating the HDR white point with the following settings:
- HDR Picture Mode: HDR Game
- Brightness: 100
- Gamma: ST2084
- Local Dimming: High
- Color Temperature: Warm 1
- Dynamic Tone Mapping: Off
The TV has decent PQ EOTF tracking, but all scenes appear brighter than the content creator's intent. There's a smooth roll-off as content approaches the its peak brightness, more so with content mastered at 4000 nits, ensuring that fine details are preserved.
It has impressive peak brightness in SDR and easily overcomes glare in a bright room. The TV maintains its brightness well across different scenes, although smaller highlights aren't as bright as bigger ones.
These measurements are after calibration with the following settings:
- Picture Mode: Theater Night
- Brightness: 100
- Color Temperature: Warm 1
- Local Dimming: High
- Gamma: 2.2
- Active Contrast: Off
The Hisense U7K TV has an excellent HDR color gamut. It has fantastic coverage of the commonly used DCI-P3 color space, although there are small tone mapping errors with most colors. It also has good coverage of the wider Rec. 2020 color space, but again, with frequent tone mapping errors with most colors.
The TV has great color volume. It displays a wide range of colors at all luminance levels, and dark saturated colors are displayed well thanks to the TV's excellent contrast.
The Hisense U75K has excellent pre-calibration accuracy. Gamma is close to the 2.2 target for a moderately lit room, and the white balance is great, with minor accuracy errors in bright whites and mid-grays. Color accuracy is excellent, although saturated blues have noticeable tone mapping errors. The color temperature is fantastic; neither too warm nor too cold.
The TV has incredible accuracy after calibration. It's a bit tricky to calibrate, as you need to calibrate it at a lower stimulus than usual; otherwise, the calibration settings don't stick. Plus, changing settings at a lower stimulus affects higher settings significantly. For example, if you change the blue levels on an 80% white stimulus, it affects the blue levels at the 85% and 90% white stimulus. Still, it already has excellent accuracy before calibration, so you don't need to calibrate it too much, if at all, for an accurate image.
See our full calibration settings.
The TV has decent gray uniformity. There's some vignetting in the corners, and the right side of the screen has a green tint, while the left side veers towards pink. These uniformity issues are noticeable in large areas of bright, uniform color, like when watching sports or browsing the web. There's visible banding in near-black scenes, with a greenish tint towards the right side of the screen.
The TV has fantastic black uniformity. With local dimming disabled, there's a bit of backlight bleed, especially visible in the upper right corner of the screen, but it isn't too distracting. Enabling local dimming almost completely eliminates the backlight bleed.
The TV has an inadequate viewing angle. The image fades and looks washed out as you move even slightly off-center. This makes it a poor choice for a wide seating arrangement, as anyone sitting off-center sees a degraded image. If you have a wide seating arrangement, an option with a wide viewing angle, like the Vizio Quantum Pro QLED, is a better choice.
The TV's reflection handling is fantastic. Its finish reduces the impact of reflections enough that it can easily handle even very bright rooms.
The TV has decent HDR gradient handling. There's some banding in dark grays, reds, and greens, as well as in bright blues. Other color gradients have minimal banding.
This Hisense U7K has very good low-quality content smoothing. It's great at avoiding macro-blocking in dark scenes and preserves fine details well.
The Hisense U7K's upscaling capabilities are good. The resulting image looks sharp overall, with some, but not excessive, blurring. Fine details are preserved well, and text is easy to read.
Sharpness processing was calibrated for low-resolution or low-bitrate content, with no over-sharpening, with the following setting:
- Super Resolution: On
- Sharpness: 10
The TV uses a BGR (blue-green-red) subpixel layout. For multimedia usage, this doesn't cause any issues, but it causes text clarity issues when you use this TV as a PC monitor. There are easy workarounds for these issues, however.
The TV has an excellent response time at 4k @ 60Hz, but the Hisense's response time tuning is different when the TV's refresh rate is below and above 100Hz: it's more aggressive above 100Hz, leading to a faster overall response time but with more overshoot errors. This doesn't cause any issues when running at a fixed refresh rate, but with VRR enabled, the TV's response time behavior rapidly changes as the TV's refresh rate hovers around 100Hz, which is very noticeable. You can see the two response time behaviors here:
Like most TVs on the market, this TV uses pulse width modulation (PWM) to dim the backlight. It flickers at 4000Hz in all picture modes and at every brightness level, but it isn't noticeable.
The TV has an optional backlight strobing feature, commonly known as black frame insertion (BFI). This feature is meant to reduce persistence blur and improve the appearance of motion. It works on the Hisense at both 60Hz and 120Hz, leading to a sharp image, but at the cost of some image duplication.
The TV has an optional motion interpolation feature to interpolate content up to 120 fps. It works decently well with slower content, like slow panning shots, but there's a lot of artifacting the moment the action ramps up.
The TV's good response time results in an adequate overall stutter performance. There's some noticeable stutter in slow-panning shots in 24p content, like movies.
The TV automatically removes judder from any source, ensuring a smooth movie-watching experience.
The Hisense U7K supports all three variable refresh rate (VRR) technologies, and its VRR range caps out at 144Hz. It can also do 1080p @ 240Hz, but not with VRR enabled. With VRR enabled, the TV sets itself to 72Hz with resolution halving when you attempt to run it at 1080p @ 240Hz.
When the TV is connected to a PC using an AMD graphics card, it disables HDR when the FreeSync toggle is enabled in the TV's Game Settings menu. For VRR and HDR to work simultaneously, FreeSync needs to be disabled on the TV, although this disables VRR for sources that only use FreeSync for VRR, such as older AMD graphic cards.
The input lag is incredibly low in Game Mode, resulting in a responsive gaming or desktop experience. The TV also outputs proper chroma 4:4:4 when in Game Mode, so you can have clear text and the fastest possible input lag when using this TV as a PC monitor.
The TV can't do 1080p @ 240Hz when VRR is enabled: it instead locks itself to 72Hz with resolution halving. With VRR disabled, the TV does proper 1080p @ 240Hz, with a measured input lag of 3.4ms.
Note: These numbers were measured with the 'High Refresh Rate' mode disabled except at 1080p @ 240Hz, as it locks itself to 'On' at that refresh rate. Enabling the setting at refresh rates lower than 240Hz noticeably increases input lag.
The TV supports up to 4k @ 144Hz on HDMI ports 3 and 4. The TV does proper 1080p @ 240Hz on HDMI ports 3 and 4, but only with VRR disabled.
The TV supports chroma 4:4:4 at 4k @ 144Hz with Game Mode enabled, so you can simultaneously have the sharpest text and lowest input lag.
The Hisense U7K takes full advantage of the PS5, with 4k @ 120Hz support on HDMI ports 3 and 4 and variable refresh rate (VRR) support.
The TV can also take full advantage of the Xbox Series X|S consoles, with 4k @ 120Hz support on HDMI ports 3 and 4, as well as variable refresh rate (VRR) support with both AMD FreeSync and HDMI Forum VRR. Like the Hisense U8/U8K, it can do Dolby Vision at 4k @ 120Hz.
The TV has HDMI 2.1 bandwidth on HDMI ports 3 and 4, with both supporting up to 4k @ 144Hz. Unfortunately, HDMI 3 is the eARC port, so you lose one HDMI 2.1 port when you plug in a soundbar. It has an ATSC 3.0 TV tuner, so it streams 4k content over-the-air. Its wireless tuner supports the Wi-Fi 6E standard, so it can use the 6GHz spectrum with compatible devices.
The TV supports eARC and can pass advanced DTS and Dolby formats from a connected source to your soundbar or sound system without reducing audio quality.
The frequency response of the built-in speakers is okay overall. There's very little bass, although it's alright for a TV. Dialogue is clear and easy to understand, but there's a pretty significant dip in the mid-to-high treble range. However, it isn't very noticeable in most content.
This TV has decent distortion performance. There's some audible total harmonic distortion, but mainly at high volume levels; it isn't noticeable at moderate volume.
The Hisense U7K uses version 12 of Google's popular Google TV OS. It's relatively easy to use and especially fast and smooth, with a large selection of apps.
Like most TVs on the market, this one has ads throughout the interface, and you can't disable them.
The TV has a great selection of streaming apps, with every popular streaming app being present. The interface is very smooth and pleasant to use.
Like most modern remotes, the included remote lacks a numpad, but there are quick-access buttons to popular streaming services. It also has a built-in mic, as does the TV itself, for hands-free voice control, giving you access to Google Assistant and Alexa. You can ask the TV to search for content, open apps, ask for the time or the weather, and switch inputs.
