ABOUT THIS TV

Samsung QE55Q70B 400x400 Image Samsung QE55Q70B

The QE55Q70B is a 55 inch 4K TV from Samsung. It was launched in 2022. It features a 10-bit VA panel with Anti-glare/Matte finish. It can achieve a max resolution of 3840 x 2160 @ 120 Hz with a pixel density of 80 ppi.

Picture Quality

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

Speaking of which, this TV is rated with a DCI P3 color profile coverage of 100% — equivalent to 136.36% sRGB. The color quality on this TV will be Lifelike!

Understanding Color Gamut

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

What this means is, it determines the ability of a display to produce accurate colors. A panel with low color gamut coverage will miss out on some colors (such as deep red), so the image produced will look "washed out" in colors.

Different manufacturers use different measurement standards to define color gamut. Viz — sRGB (most popular), NTSC 1953, DCI P3 Adobe RGB and rec.2020.

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

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

Color Gamut Chart

Now, next in the list is Static Contrast.

Understanding the static contrast specification

The static contrast ratio of a TV corresponds to its Black levels. A TV with low static contrast ratio (<1000:1) will not produce deep blacks. Moreover, such displays may suffer from backlight bleeds such as this:

Clearly this will impact your viewing experience, 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, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.

This TV is rated with a static contrast ratio of 8000:1., well enough to achieve deep blacks. For the record, it also comes with local dimming technology which is a plus.

HDR10, HLG (Hybrid Log Gamma), HDR10+, HDR10+ Adaptive, HDR10+ Gaming and Quantum HDR are also supported on this TV.

Coming to brightness, the peak brightness the TV can achieve is 250 nits, powered by Edge LED backlight.

Gaming Performance

If you are planning to use your TV solely for content consumption, you can safely ignore these specs. But if you are also going to use the TV for gaming or use it as a PC monitor, you would want to get a TV that features the lowest input lag and response time.

Unfortunately, we cannot find the input lag specification for this unit. Now, since this is not a cheap TV from Samsung, input lag on this TV could be 20ms or below.

What is Input Lag and Why it matters ?

This lag is the latency at which your inputs 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, get a TV that features an input lag and response time of < 20ms.

Dimensions and Ergonomics

The width of this TV is 48.54 inches while its height is 30.48 inches.

It is just 1 inches thick.

It weighs approximately 16.1 kilograms and an additional 0.8 kgs if you include stand. So plan your space accordingly.

Speaking of 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. There is no Swivel, Tilt or Pivot feature support in this TV.
