The QN75QN800B is a 75 inch 8K TV from Samsung. It was launched in 2022. It comes with a True 10-bit IPS panel with Anti-glare/Matte finish. The max. resolution it can achieve is 7680 x 4320 with a refresh rate of 120 Hz and a pixel density of 118 ppi.
Now, the next important feature of a display that will impact your viewing experience is Color Gamut.
This TV comes with 100% DCI P3 color gamut coverage — equivalent to 136.36% sRGB coverage. The color accuracy on this TV will be Lifelike!
What is Color gamut ?
Color gamut specification of a display indicates the range of colors that the TV can display.
In layman terms, it indicates the ability of a display to produce accurate colors. A TV with low gamut coverage will miss out on some colors (such as deep red), the result would be a "washed out" picture quality.
Different manufacturers use different units to specify color gamut. Viz — sRGB, NTSC, DCI P3 etc.
In case of this TV, it is specified in DCI P3.
But don't worry, below is a chart that will help you choosing a TV with good color accuracy.
After color gamut, you should look at the static contrast specification as it impacts the picture quality the same way.
Understanding the static contrast specification
A TV with low static contrast ratio will not produce deep blacks and may bleed backlight as shown in the below image:The image is an example of another display, it is not this one
The static contrast ratio of above TV is rated 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, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV is rated with a static contrast ratio of 10000:1., enough to produce deep blacks and eye-catching visuals. The panel comes with local dimming feature which is a plus.
HDR is also supported on this TV in form of HDR10, HDR10+, HDR10+ Adaptive, HDR10+ Gaming, HLG (Hybrid Log Gamma) and Quantum HDR 32X.
Coming to brightness, it can go as bright as 250 nits, powered by Mini LED backlight technology.
Now if you are going to use the TV other than watching videos — like as a PC monitor or for gaming purposes, you would want to get a TV that features the lowest input lag. For gaming, both the input lag and response time affects the performance.
Unfortunately, we cannot find the input lag specification for this unit. But as this is not a cheap TV from Samsung, we can expect an input lag of less than 20ms.
What is Input lag ?
This lag is the amount of time at which 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 features an input lag and response time of < 20ms.
