The QN65LS03B 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.
The maximum resolution it can display is 3840 x 2160 @ 120 Hz with a pixel density of 68 ppi.
After screen size and resolution, the next important feature to look for in a display is its Color Reproduction, which is defined by its color gamut specification.
Speaking of which, this TV is rated with a 100% DCI P3 color gamut coverage — equivalent to 136.36% sRGB. The color accuracy on this TV should be Lifelike!
Understanding the Color Gamut Specification
Color gamut spec of a display is a measure of the range of colors that it can display.
A panel with poor color reproduction will produce undersaturated/washed out colors that will not be pretty to look at.
It is specified in different units - sRGB(most popular), NTSC 1953, DCI P3 etc.
For example, the color gamut of this TV is specified in 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.
After color gamut, the static contrast of a TV also impacts its picture quality.
Why its important?
The static contrast ratio of a TV corresponds to its Black levels. A Display with low static contrast ratio (less than 1000:1) will not produce deep blacks. Moreover, such displays may suffer from backlight bleeds such as below:The image is an example of another display, it is not this one
Needless to say, this will impact your experience, especially in a dark room.
Other than black levels, a TV with high constrast ratio lets you to see more details. So, resolution and static contrast ratio go hand in hand.
This TV features a static contrast ratio of 8000:1., good enough to achieve deep blacks and eye-catching visuals. The panel comes with local dimming feature 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 can go as bright as 250 nits. The backlight used on the panel is Edge LED.
If you aren't into gaming, 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, make sure to get a TV with the lowest input lag and response time.
Unfortunately, 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.
What is Input Lag and Why it matters ?
This lag is the latency at which key-presses/mouse movements changes the content of your display. For casual Non-FPS games, input lag doesn't matter much.
Although for better experience, look for a TV that comes with an input lag and response time of < 20ms.

It is just 1 inches thick.
