Launched in the year 2022, the QN85Q70B is a 85" 4K TV from Samsung. It features a 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 52 ppi.
After screen size and resolution, the next important feature to look for in a display is its Color Reproduction Accuracy, which is defined by its color gamut specification.
Speaking of which, this TV is rated with a 100% DCI P3 color gamut coverage, which is equivalent to 136.36% sRGB. The color quality on this TV should be Lifelike!
Understanding Color Gamut
Color gamut specification of a TV indicates the range of colors that it can display.
In other words, it tells 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), the result would be a "washed out" picture quality.
Different manufacturers use different measurement standards to define color gamut. Viz — sRGB (most popular), NTSC 1953, DCI P3 to name a few.
For example, the color gamut of this TV is specified in terms of DCI P3.
But don't worry, here 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 has equally important role in picture quality.
Understanding Static Contrast
A TV with high enough static contrast ratio will produce deep blacks while a TV with low contrast ratio (<1000:1) will produce images that might look dusty as shown below.
As you can see, this will impact your experience considerably.
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.
This TV features a static contrast ratio of 8000:1., good enough to achieve deep blacks and eye-catching visuals. For the record, it also comes with local dimming technology which is a plus.
HDR is also supported on this TV in form of HDR10, HLG (Hybrid Log Gamma), HDR10+, HDR10+ Adaptive, HDR10+ Gaming and Quantum HDR.
Coming to brightness, it can go as bright as 250 nits. The backlight used on the panel is Edge LED.
If you are not interested in gaming, you can safely ignore these specifications. But if you are also going to use the TV for gaming or use it as a PC monitor, make sure to take a TV with the lowest input lag and response time.
Unfortunately, Samsung did not specify the input lag on this unit. But as this is not a cheap TV from Samsung, input lag on this TV could be 20ms or below.
Understanding Input lag and response time
This lag is the latency at which key-presses/mouse movements changes the content of the TV. For casual Non-FPS games, input lag doesn't matter much.
But ideally, look for a TV that features 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 600 x 400 mm. The unit doesn't come with Swivel, Tilt or Pivot support.
The width of this TV is 74.87 inches while its height is 45.52 inches. It is 1 inches thick. It weighs around 43.8 Kgs, another 7.1 kgs if you include stand. So plan your space accordingly.
