The QE75QN85B is a 75 inch 4K TV from Samsung, launched in the year 2022. It features a True 10-bit VA panel with Anti-glare/Matte finish. The maximum resolution it can achieve is 3840 x 2160 @ 120 Hz with a pixel density of 59 ppi.
Now, the very next feature of a display that impacts picture quality is Color Gamut.
This TV features 100% DCI P3 color gamut coverage — equivalent to 136.36% sRGB. The color accuracy on this TV should be Lifelike!
What Color Gamut means ?
Color gamut specification of a TV indicates the range of colors that it can show.
Meaning, this specification determines the ability of a TV to produce accurate colors. A panel with low gamut coverage will miss out on some colors (such as deep red), thus producing a "washed out" picture.
It is specified in different units - sRGB(most popular), NTSC, DCI P3 to name a few. It is upto the manufacturer which one they choose.
As for this TV it 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 specification of a TV holds almost equal role in picture quality.
Understanding Static Contrast
The static contrast ratio of a TV corresponds to its Black levels. A Display with low static contrast ratio (<1000:1) will not produce deep blacks. Also, such displays are likely to suffer from backlight bleeds such as below:The image is an example of another display, it is not this one
Needless to say, this will affect your viewing experience considerably, especially in a dark room.
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, thus 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., good enough to display deep blacks and eye-catching visuals. The panel comes with local dimming backlight technology which is a plus.
HDR10, HDR10+, HDR10+ Adaptive, HDR10+ Gaming, HLG (Hybrid Log Gamma) and Quantum HDR 1500 are also supported on this TV, so that's a plus.
As for brightness, it can go as bright as 250 nits. The panel of this TV is powered by Mini LED backlight technology.
If you are planning to use your TV just for content consumption, you can ignore these specs. But if you are also planning to use the TV for playing games or use it as a PC monitor, you would want to get a TV with the lowest input lag and response time.
The input lag on the Samsung QE75QN85B is 6 ms and its minimum response time is N/A. For a TV, its the best you can get for gaming.
Understanding Input lag and response time
This lag is the amount of time at which your device inputs 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.
Ergonomics and Dimensions
Speaking of ergonomics — VESA mount is supported on this TV with an interface size of 400 x 400 mm. The unit doesn't come with either Swivel, Tilt or Pivot support.
Vertically, the TV measures 75 inches and horizontally 65.75 inches. Speaking of thickness, it is 1 inches thick. It weighs around 34.0 kilograms and 5.9 kgs extra if you include stand.
