The QE75QN900B is a 75 inch 8K TV from Samsung. It was launched in 2022. It features a True 10-bit VA panel with Anti-glare/Matte finish. It can achieve a maximum resolution of 7680 x 4320 @ 120 Hz with a pixel density of 118 ppi.
After screen size and resolution, the next important feature to look for in a display is its Color Reproduction Accuracy (defined by its color gamut specification).
The Samsung QE75QN900B comes with a DCI P3 coverage of 100% — equivalent to 136.36% sRGB. The color accuracy on this TV should be Lifelike!
What Color Gamut means ?
Color gamut spec of a display indicates the range of colors that the display can display.
A TV with poor color accuracy will produce undersaturated/washed out colors that will spoil your immersive experience.
Different manufacturers use different measurement standards to define color gamut. Such as — sRGB, NTSC 1953, DCI P3 to name a few.
As for this TV its color gamut is specified in DCI P3.
But don't worry, below is a chart that you can use to choose a TV with good color accuracy.
After color gamut, the static contrast ratio of a TV holds almost equal role in picture quality.
The importance of static contrast ratio
A TV with low static contrast ratio will not produce deep blacks and may bleed backlight as in the below image:The image is an example of another display, it is not this one
The above TV's static contrast is 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More is better.
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, I will 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., good enough to display deep blacks and eye-catching visuals. The panel comes with local dimming technology which is a plus.
HDR10, HDR10+, HDR10+ Adaptive, HDR10+ Gaming, HLG (Hybrid Log Gamma) and Quantum HDR 4000 are also supported on this TV, so that's a plus.
As for brightness, it is can achieve a maximum luminance of 250 nits. The backlight of this TV is powered by Mini LED technology.
If you are planning to use your TV other than watching videos — like as a PC monitor or for gaming purposes, you should take a TV that features the lowest input lag. For gaming however, both the input lag and response time affects the performance.
The input lag on this TV is 6 ms and its minimum response time is N/A. Gamers gonna love this TV.
What is Input Lag and Why it matters ?
This lag is the latency at which key-presses or 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.
But ideally, get a TV that has an input lag and response time of < 20ms.
