The QN75LS03B is a 75 inch 4K TV from Samsung, launched in the year 2022. It comes with a 10-bit VA panel with Anti-glare/Matte finish. The max. resolution it can achieve is 3840 x 2160 with a refresh rate of 120 Hz and a pixel density of 59 ppi.
After screen size and resolution, the next important specification of a display that will impact your viewing experience is its Color Gamut.
Speaking of which, this TV comes with a DCI P3 color gamut coverage of 100%. FYI, this is equivalent to 136.36% sRGB. The color accuracy on this TV will be Lifelike!
Understanding Color Gamut
Color gamut spec of a TV indicates the range of colors that the TV can produce.
What this means is, this specification indicates 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.
It is specified in different units - sRGB(most popular), NTSC 1953, DCI P3 etc. It is upto the manufacturer which one they choose.
For example, the color gamut of this TV is specified using DCI P3.
But don't worry, here is a chart that will help you choosing a TV with good color accuracy.
Other than color accuracy, the static contrast specification of a TV holds almost equal role in picture quality.
Understanding the static contrast ratio
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 look dusty as shown in the below image.
As you can see, this will impact 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.
This TV comes with a static contrast ratio of 8000:1., enough to produce deep blacks. The panel comes with local dimming backlight which is a plus.
HDR10, HDR10+, HDR10+ Adaptive, HDR10+ Gaming, HLG (Hybrid Log Gamma) and Quantum HDR are also supported on this TV.
Coming to brightness, it is can achieve a maximum luminance of 250 nits. The panel of this TV is powered by Edge LED backlight technology.
If you aren't planning to game on this TV, you can safely ignore these specifications. But if you are also planning to use the TV for playing games or use it as a PC monitor, you should get a TV that features the lowest input lag and response time.
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 ?
This lag is the latency at which key-presses/mouse movements changes the content of your TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
Although for better experience, get a TV that comes with an input lag and response time of < 20ms.
Ergonomics and Dimensions
Coming to 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 400 x 400 mm. However, there is no Tilt or Pivot support on this unit except Swivel support.
Vertically, the TV measures 75 inches and horizontally 66.2 inches. In terms of thickness, it is just 1.1 inches thick. It weighs 35.29 kgs and 0.59 kgs extra if you include stand.
