ABOUT THIS TV

Samsung QE43QN90B 400x400 Image Samsung QE43QN90B

The QE43QN90B is a 43 inch 4K TV from Samsung, launched in the year 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 103 ppi.

Picture Quality

Now, the very next spec of a display that impacts picture quality is Color Gamut.

The Samsung QE43QN90B is rated with a DCI P3 coverage of 100%. This is equivalent to 136.36% sRGB. The color quality on this TV will be Lifelike!

Understanding Color Gamut

Color gamut spec of a TV is a measure of the range of colors that the TV can show.

What this means is, it tells the ability of a TV to produce accurate colors. A TV 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 units to define color gamut. Viz — sRGB, NTSC, DCI P3 to name a few.

In case of this TV, its color gamut is specified in DCI P3.

But don't worry, here is a chart that will help you choosing a TV with good color accuracy.

Color Gamut Chart

Other than color accuracy, the static contrast of a TV also impacts its picture quality.

Understanding Static Contrast

The 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 displays are likely to suffer from backlight bleeds such as this:

Obviously this will impact your viewing experience considerably, especially in a dark room.

Think of static contrast as another dimension to details — just like resolution. 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., well enough to produce 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 1500.

Coming to brightness, it can go as bright as 250 nits. The backlight used on the panel is Mini LED.

Gaming Performance

If you are going to use the TV other than using it as a TV — like as a PC monitor or Gaming, make sure to get a TV with lowest input lag. For gaming however, both 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. Gamers gonna love this TV.

What is Input Lag and Why it matters ?

This lag is the latency at which 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.

Although for better experience, look for a TV that comes with an input lag and response time of < 20ms.

Ergonomics and Dimensions

Speaking of ergonomics — a VESA mount with interface size of 200 x 200 mm is provided for wall-mounting. There is no Swivel, Tilt or Pivot feature support in this TV.

The width of this TV is 37.83 inches while its height is 24.54 inches. It is 1 inches thick. Overall the TV weighs approximately 13.8 kgs including its stand. Without stand, it weighs 9.2 Kgs.
