The QN55QN85B is a 55 inch 4K TV from Samsung. It was launched in 2022. It comes with a True 10-bit IPS panel with Anti-glare/Matte finish.
It can display a max resolution of 3840 x 2160 with a refresh rate of 120 Hz and pixel density of 80 ppi.
After screen size and resolution, the next important specification of a display is its Color Reproduction (defined by its color gamut specification).
Speaking of which, this TV comes with a DCI P3 gamut coverage of 100%, which is equivalent to 136.36% sRGB. The color quality on this TV should be Lifelike!
Understanding Color Gamut
Color gamut spec of a display indicates the range of colors that the display can display.
Put Simply, it indicates the ability of a display to produce accurate colors. A display with low color gamut coverage will miss out on some colors (such as deep red), thus producing a "washed out" picture.
Different manufacturers use different units to specify color gamut. Such as — sRGB, NTSC 1953, DCI P3 Adobe RGB and rec.2020.
As for this TV its color gamut is specified using 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, you should look at the static contrast specification as it influences the picture quality substantially.
What is Static Contrast ?
A TV with low static contrast ratio will not produce deep blacks and may bleed backlight as in the images below: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.
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 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 features a static contrast ratio of 8000:1., enough to achieve deep blacks. For the record, it also comes with local dimming 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 24X.
As for brightness, the peak brightness it can achieve is 250 nits. The backlight used on the panel is Mini LED.
If you are going to use a TV other than using it as a TV — say as a PC monitor or for gaming purposes, make sure to get a TV that features the lowest input lag. For gaming, both the input lag and response time impacts the performance.
The input lag on this TV is 6 ms and its minimum response time is N/A. Pick this one if you are a gamer.
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, get a TV that has an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Coming to ergonomics — a VESA mount with interface size of 200 x 200 mm is provided for wall-mounting. Swivel, Tilt or Pivot features are not supported on this unit.
The width of this TV is 48.32 inches while its height is 30.23 inches.
It is just 1 inches thick.
It weighs approximately 17.2 Kgs and an additional 3.0 kgs if you include stand. So plan your space accordingly.
