ABOUT THIS TV

Samsung QN43QN90B 400x400 Image Samsung QN43QN90B

The QN43QN90B is a 43 inch 4K TV from Samsung. It was launched in 2022. It comes with a True 10-bit IPS panel with Anti-glare/Matte finish. The maximum resolution it can display is 3840 x 2160 @ 120 Hz with a pixel density of 103 ppi.

Picture Quality

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

The Samsung QN43QN90B comes with a DCI P3 coverage of 100% — equivalent to 136.36% sRGB coverage. The color accuracy on this TV will be Lifelike!

What Color Gamut means ?

Color gamut spec of a display is a measure of the range of colors that it can display.

In other words, this specification 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), thus producing a "washed out" picture.

It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 to name a few.

For example, the color gamut of this TV is specified in 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.

Next in the list of important specifications is Static Contrast.

Why its important?

There are two types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio as dynamic doesn't matter much.

Static contrast specification defines the intensity of black levels. That is, a TV with SC ratio less than 1000:1 may produce black images something like this:

Example of a disply with low contrast ratio

Apart from that, such TVs are likely to suffer from backlight bleeds that will rob your experience — as shown below.

Also, 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.

If given a choice, I will 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. For the record, it also comes with local dimming 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.

Coming to brightness, it can go as bright as 250 nits. The backlight of this TV is powered by Mini LED technology.

Gaming Performance

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, make sure to get a TV that features the lowest input lag and response time.

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 latency at which key-presses or mouse movements changes the content of the TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.

For best of both worlds, look for a TV that comes with an input lag and response time of less than 20ms.

Dimensions and Ergonomics

The vertical and horizontal measurements of this TV are 37.83 inches and 24.54 inches respectively.

It is just 1 inches thick. It weighs approximately 9.2 kgs, another 4.6 kgs including stand.

Now, coming to ergonomics — VESA mount is supported on this TV with an interface size of 200 x 200 mm. The unit doesn't come with Swivel, Tilt or Pivot support.
