The QN55Q70B is a 55 inch 4K TV from Samsung, launched in the year 2022. It features a 10-bit VA panel with Anti-glare/Matte finish.
It can display a maximum resolution of 3840 x 2160 with a refresh rate of 120 Hz and pixel density of 80 ppi.
After screen size and resolution, the next important spec of a display that impacts picture quality is its Color Gamut.
This TV comes with 100% DCI P3 color gamut coverage. 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 indicates the range of colors that the display can produce.
A panel with poor color reproduction will produce washed out colors that will spoil the immersion.
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.
For example, the color gamut of this TV is specified in terms of DCI P3.
But don't worry, below is a chart that will help you choosing a TV with good color accuracy.
Other than color accuracy, you should look at the static contrast specification as it influences the picture quality substantially.
Why its important?
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 will look muddy as shown in below image.
As you imagine, this will affect your experience considerably.
Other than black levels, a TV with high constrast ratio allows you to see more details. So, resolution and static contrast ratio go hand in hand in a sense.
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., good enough to achieve deep blacks and eye-catching visuals. For the record, it also comes with local dimming backlight which is a plus.
HDR10, HLG (Hybrid Log Gamma), HDR10+, HDR10+ Adaptive, HDR10+ Gaming and Quantum HDR are also supported on this TV, so that's a plus.
Coming to brightness, the peak luminance the Samsung QN55Q70B can produce is 250 nits. The backlight of this TV is powered by Edge LED technology.
If you are planning to use your TV other than using it as a TV — like as a PC monitor or Gaming, you should take a TV with lowest input lag. For gaming however, both input lag and response time affects the performance.
Sadly, we cannot find the input lag specification for this unit. Now, since this is not a cheap TV, we can expect an input lag of less than 20ms.
What is Input Lag and Why it matters ?
This lag is the latency at which key-presses or 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.
But ideally, look for a TV that comes with an input lag and response time of less than 20ms.
Dimensions and Ergonomics
The TV measures 55 inches vertically and 48.54 inches horizontally.
It is just 1 inches thick. In total this TV weighs 16.9 KGs including stand. Without stand, it weighs 16.1 kgs.
Now, speaking of ergonomics — a VESA mount with interface size of 200 x 200 mm is provided for wall-mounting. However, there is no Swivel, Tilt or Pivot feature support in this TV.
