Launched in the year 2022, the QN50QN90B is a 50" 4K TV from Samsung. It features a True 10-bit VA panel with Anti-glare/Matte finish.

It can achieve a maximum resolution of 3840 x 2160 @ 120 Hz with a pixel density of 89 ppi.

Picture Quality

After screen size and resolution, the next most important feature to look for in a display is its Color Reproduction (defined by its color gamut specification).

The Samsung QN50QN90B features 100% DCI P3 color gamut coverage. Incase you're wondering, this is equivalent to 136.36% sRGB coverage. The color accuracy on this TV will be Lifelike!

Understanding Color Gamut

Color gamut specification of a display indicates the range of colors that the TV can produce.

In layman terms, this specification tells 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), so the image produced will look "washed out" in colors.

It is specified in different units - sRGB(most popular), NTSC, DCI P3 etc.

For example, the color gamut of this TV is specified using DCI P3.

But you don't need to worry about that, here is a chart that you can use to choose a TV with good color accuracy.

Color Gamut Chart

Now, next in the list that will impact your experience is Static Contrast.

What is Static Contrast ?

Static contrast ratio of a TV corresponds to its Black levels. A Display with low static contrast ratio (less than 1000:1) will not produce deep blacks. Moreover, such TVs often suffer from backlight bleeds such as this:

Obviously this will affect your experience, especially in a dark room.

Also note, 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, always 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 8000:1., well enough to produce deep blacks. 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 is capable of producing a peak brightness of 250 nits, powered by Mini LED backlight.

Gaming Performance

Now if you are planning to use your TV other than using it as a TV — like as a PC monitor or for gaming purposes, you should take a TV that features the lowest input lag. For gaming, both 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 amount of time at which your key-presses/mouse movements changes the content of the screen. 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 comes with an input lag and response time of less than 20ms.

Ergonomics and Dimensions

Now, coming to ergonomics — If you plan to wall mount the TV, you can make use of the VESA mount provided with this TV, which by the way has an interface size of 200 x 200 mm. The unit doesn't come with Swivel, Tilt or Pivot support.

Vertically, the TV measures 50 inches and horizontally 43.84 inches.

It is just 1 inches thick.

In total it weighs 18.6 KGs (including stand). Without stand, it weighs 14.0 Kgs. So plan your space accordingly.
