The 75U7H is a 75 inch 4K TV from Hisense, launched in the year 2022. It features a 10-bit VA panel.
It can display a max resolution of 3840 x 2160 with a refresh rate of 120 Hz and pixel density of 59 ppi.
Picture Quality
After screen size and resolution, the next important feature to look for in a display is its Color Reproduction (defined by its color gamut specification).
This TV doesn't come with a color gamut specification, so we have to take a guess. Considering the TV features amassive 75 inch screen, it won't come with a cheap panel, so here we can assume its equivalent sRGB coverage to be 90-100% or above. Undoubtedly The color quality on this TV should be Lifelike! It will produce accurate colors by default.
Understanding the Color Gamut Specification
Color gamut spec of a TV indicates the range of colors that the TV can display.
What this means is, it determines the ability of a TV to produce accurate colors. A display with low color gamut coverage will miss out on some colors (such as deep red), so the image produced will look "washed out" in colors.
Different manufacturers use different measurement standards to define color gamut. Viz — sRGB (standard RGB), NTSC 1953, DCI P3 to name a few.
But you don't need to worry about that, here is a chart that you can use to choose a TV with good color accuracy.
Now, after color gamut, the static contrast of a TV also impacts its picture quality.
Understanding Static Contrast
The static contrast ratio of a TV corresponds to its Black levels. A Display with low static contrast ratio (<1000:1) will not produce deep blacks. Apart from this, such TVs may suffer from backlight bleeds such as below:
The image is an example of another display, it is not this oneNeedless to say, this will impact your viewing experience considerably, especially in a dark room.
Think of static contrast as another dimension to details — just like resolution. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, so lesser detail overall.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV comes with a static contrast ratio of 2500 : 1., enough to produce deep blacks and eye-catching visuals. For the record, it also comes with local dimming feature which is a plus.
Dolby Vision, Dolby Vision IQ, HDR10 and HLG (Hybrid Log Gamma) are also supported on this TV, so that's a plus.
Coming to brightness, the peak luminance the TV can produce is 799 nits. The panel of this TV is powered by Direct LED (Full-Array Local Dimming) backlight. This amount of brightness is good enough even for a well-lit room!
Gaming Performance
If you are not into gaming, you can ignore these specs. But if you are also planning to use the TV for playing games or use it as a PC monitor, make sure to take a TV with the lowest input lag and response time.
Unfortunately, there is no specification for input lag on this TV. Now, as this is not a cheap TV, we can expect an input lag of less than 20ms.
Understanding Input lag and response time
This lag is the latency at which device inputs changes the content of your TV. For casual Non-FPS games, input lag doesn't matter much.
For best of both worlds, get a TV that comes with an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Now, coming to ergonomics — a VESA mount with interface size of 400 x 300 mm is provided for wall-mounting. The unit doesn't come with Swivel, Tilt or Pivot support.
The TV measures 75 inches vertically and 65.91 inches horizontally.
Speaking of thickness, it is just 3.11 inches thick. Overall, it weighs approximately 22.5 kilograms.
