The QE75Q65B is a 75 inch 4K TV from Samsung. It was launched in 2022. It features a 10-bit VA panel. It can achieve a maximum resolution of 3840 x 2160 @ 60 Hz with a pixel density of 59 ppi.
After screen size and resolution, the next most important specification of a display is its Color Reproduction Accuracy (defined by its color gamut specification).
The Samsung QE75Q65B comes with a DCI P3 color gamut coverage of 100%. Incase you're wondering, this is equivalent to 136.36% sRGB. The color accuracy on this TV will be Lifelike!
What Color Gamut means ?
Color gamut specification of a TV indicates the range of colors that the TV can display.
A TV with poor color reproduction will produce undersaturated colors that will spoil your immersive experience.
Different manufacturers use different units to define color gamut. Such as — sRGB (most popular), NTSC, DCI P3 Adobe RGB and rec.2020.
For example, the color gamut of this TV is specified in terms of DCI P3.
But you don't need to worry about that, below is a chart that will help you choosing a TV with good color accuracy.
After color gamut, the static contrast of a TV similarly impacts its picture quality.
Understanding the static contrast ratio
There are 2 types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio. Dynamic doesn't matter much.
Static contrast specification defines the intensity of black levels. That is, a TV with SC ratio < 1000:1 may produce black images something like this:
Note that, such TVs may suffer from backlight bleeds that will impact your experience — as shown below.The image is an example of another display, it is not this one
Note that, 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 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 is rated with a static contrast ratio of 8000:1., enough to achieve deep blacks and eye-catching visuals. For the record, it also comes with local dimming feature which is a plus.
HDR10, HLG (Hybrid Log Gamma), HDR10+, HDR10+ Adaptive and Quantum HDR are also supported on this TV, so that's a plus.
As for brightness, it is capable of producing a maximum luminance of 250 nits with the help of Edge LED backlight.
If you are planning to use your TV just for content consumption, you can safely ignore these specifications. But if you are also going to use the TV for playing games or use it as a PC monitor, you should get a TV with the lowest input lag and response time.
Sadly, Samsung did not specify the input lag on this unit. But 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 amount of time at which your 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 has an input lag and response time of less than 20ms.
