The 75U800GR is a 75 inch 8K TV from Hisense, launched in the year 2021. It comes with a 10-bit IPS panel with Anti-glare/Matte finish.
It can achieve a max resolution of 7680 x 4320 with a refresh rate of 120 Hz and pixel density of 118 ppi.
After screen size and resolution, the next important spec of a display is its Color Reproduction (defined by its color gamut specification).
Hisense did not provide a color gamut rating for this TV. But don't worry, we have other means to guess that. Now, since the TV features a big 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. The color accuracy on this TV should be Lifelike! It will produce accurate colors out of the box.
What is Color gamut ?
Color gamut specification of a TV indicates the range of colors that it can show.
Meaning, this specification indicates the ability of a TV to produce accurate colors. A TV 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 units to define color gamut. Viz — sRGB, NTSC, 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.
After color gamut, next in the list of important specifications is Static Contrast.
Understanding Static Contrast
A TV with low static contrast ratio will not produce deep enough blacks and may bleed backlight as below:The image is an example of another display, it is not this one
The static contrast ratio of above TV is 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More is better.
Also note, static contrast ratio and resolution go hand in hand when it comes to details. 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 10000:1., well enough to achieve deep blacks. The panel comes with local dimming which is a plus.
HDR is also supported on this TV in form of Dolby Vision, HDR10, HLG (Hybrid Log Gamma), HDR10+ and Dolby Vision IQ.
Coming to brightness, it can go as bright as 1000 nits. The backlight of this TV is powered by Direct LED (Full-Array Local Dimming Pro) technology. This amount of brightness is good enough even for a well-lit room!
If you are not into gaming, you can ignore these specs. But if you are also going to use the TV for playing games or use it as a PC monitor, make sure to get a TV that features the lowest input lag and response time.
Unfortunately, Hisense did not specify the input lag on this unit. But as this is not a cheap TV from Hisense, we can expect an input lag of less than 20ms.
Understanding Input lag and response time
This lag is the amount of time at which key-presses/mouse movements changes the content of your TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
For best of both worlds, look for a TV that has an input lag and response time of < 20ms.
Dimensions and Ergonomics
The TV measures 75 inches vertically and 65.98 inches horizontally.
It is 2.99 inches thick.
Overall this TV weighs approximately 38.2 KGs including its stand. Without stand, it weighs 37.0 Kilograms. So plan your space accordingly.
Now, coming to ergonomics — If you plan to wall mount the TV, you can make use of the VESA mount provided with this TV, which by the way has an interface size of 600 x 400 mm. Swivel, Tilt or Pivot features are not supported on this unit.
