Launched in the year 2022, the QN85QN90B is a 85" 4K TV from Samsung. It features a True 10-bit VA panel with Anti-glare/Matte finish.
The max. resolution it can achieve is 3840 x 2160 with a refresh rate of 120 Hz and a pixel density of 52 ppi.
After screen size and resolution, the next most important spec of a display is its Color Reproduction, which is defined by its color gamut specification.
Speaking of which, this TV is rated with a 100% DCI P3 color gamut coverage. Incase you're wondering, this is equivalent to 136.36% sRGB coverage. The color accuracy on this TV should be Lifelike!
What is Color gamut ?
Color gamut spec of a display indicates the range of colors that the display can show.
A TV with poor color reproduction will produce undersaturated colors that will spoil the immersion.
Different manufacturers use different units to specify color gamut. Such as — sRGB (most popular), NTSC, DCI P3 to name a few.
For example, the color gamut of this TV is specified using DCI P3.
But you don't need to worry about that, below is a chart that will help you choosing a TV with good color accuracy.
After color gamut, next in the list of important specifications that will impact your experience is Static Contrast.
What is Static Contrast ratio ?
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 rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More is better.
Note that, 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 show both dark gray and black as black, 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 8000:1., enough to achieve deep blacks. For the record, it also comes with local dimming backlight 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.
As for brightness, the peak luminance the TV can produce is 250 nits, which is powered by Mini LED backlight.
If you are not into gaming, you can ignore these specifications. But if you are also planning to use the TV for playing games or use it as a PC monitor, you should get a TV with the lowest input lag and response time.
The input lag on the Samsung QN85QN90B is 6 ms and its minimum response time is N/A. For a TV, its the best you can get for gaming.
What is Input lag ?
This lag is the latency at which device inputs changes the content of your display. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
Although for better experience, get a TV that has an input lag and response time of less than 20ms.
