ABOUT THIS TV

Samsung QN65Q70B 400x400 Image Samsung QN65Q70B

The QN65Q70B is a 65 inch 4K TV from Samsung. It was launched in 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 68 ppi.

Picture Quality

After screen size and resolution, the next important specification of a display is its Color Reproduction Accuracy (defined by its color gamut specification).

The Samsung QN65Q70B is rated with a DCI P3 coverage of 100%. FYI, this is equivalent to 136.36% sRGB coverage. The color accuracy on this TV should be Lifelike!

What Color Gamut means ?

Color gamut spec of a display is the measurement of the range of colors that the display can produce.

Put Simply, it tells the ability of a display to produce accurate colors. A display with low gamut coverage will miss out on some colors (such as deep red), the result would be a "washed out" picture quality.

It is specified in different units - sRGB,sRGB (standard RGB), NTSC 1953, DCI P3 to name a few. It is upto the manufacturer which one they choose.

In case of this TV, it is specified using DCI P3.

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

Color Gamut Chart

Now, after color gamut, the static contrast ratio of a TV holds almost equal role in picture quality.

What is Static Contrast ratio ?

A TV with low static contrast ratio will not produce deep blacks and can bleed backlight as in the images below:

Backlight bleed exampleThe image is an example of another display, it is not this one

The static contrast ratio of above TV is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. More the better.

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, thus 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 is rated with a static contrast ratio of 8000:1., enough to produce deep blacks. The panel comes with local dimming feature which is a plus.

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

As for brightness, it is capable of producing a peak brightness of 250 nits. The backlight of this TV is powered by Edge LED technology.

Gaming Performance

Now if you are going to use your TV other than using it as a TV — like as a PC monitor or for gaming purposes, you should get a TV with lowest input lag. For gaming, both input lag and response time affects the performance.

Sadly, there is no specification for input lag on this TV. But since this is not a cheap TV from Samsung, input lag on this TV could be 20ms or below.

Understanding Input lag and response time

This lag is the amount of time at which 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.

But ideally, get a TV that has an input lag and response time of less than 20ms.

Ergonomics and Dimensions

Now, coming to ergonomics — VESA mount is supported on this TV with an interface size of 400 x 300 mm. The unit doesn't come with Swivel, Tilt or Pivot support.

The TV measures 65 inches vertically and 57.15 inches horizontally. It is just 1 inches thick. Overall this TV weighs approximately 22.3 KGs including its stand. Without stand, it weighs 21.4 Kilograms. So plan your space accordingly.

The UI on this TV is powered by Tizen 6.5 Operating System.
