The QN55LS03B is a 55 inch 4K TV from Samsung, launched in the year 2022. It features a 10-bit VA panel with Anti-glare/Matte finish. It can achieve a maximum resolution of 3840 x 2160 @ 120 Hz with a pixel density of 80 ppi.
After screen size and resolution, the next most important feature of a display is its Color Reproduction, which is defined by its color gamut specification.
The Samsung QN55LS03B is rated with a DCI P3 coverage of 100% — equivalent to 136.36% sRGB coverage. The color accuracy on this TV should be Lifelike!
What Color Gamut means ?
Color gamut specification of a display is the measurement of the range of colors that it can show.
A panel with poor color accuracy will produce washed out colors that will spoil the immersion.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 to name a few. It is upto the manufacturer which one they choose.
For example, the color gamut of this TV 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.
Now, after color gamut, the static contrast of a TV also impacts its picture quality.
Understanding the static contrast ratio of a TV
There are 2 types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio as dynamic doesn't matter much.
This defines the intensity of black levels. That is, a TV with SC ratio less than 1000:1 may produce black images something like this:
Note that, such TVs are also prone backlight bleeds that will impact your experience — as shown below.The image is an example of another display, it is not this one
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.
If given a choice, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV features a static contrast ratio of 8000:1., well enough to display deep blacks. The panel comes with local dimming feature which is a plus.
HDR is also supported on this TV in form of HDR10, HDR10+, HDR10+ Adaptive, HDR10+ Gaming, HLG (Hybrid Log Gamma) and Quantum HDR.
As for brightness, it is capable of producing a peak luminance of 250 nits, which is powered by Edge LED backlight.
If you are not into gaming, you can ignore these specs. But if you are also planning to use the TV for playing games or use it as a PC monitor, you would want to take a TV that features the lowest input lag and response time.
Sadly, there is no specification for input lag on this TV. Now, as 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 device inputs 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 has an input lag and response time of < 20ms.
Ergonomics and Dimensions
Now, 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 200 x 200 mm. There is no Tilt or Pivot support in this unit except Swivel support.
Vertically, the TV measures 55 inches and horizontally 48.7 inches.
In terms of thickness, it is 1 inches thick. In total this TV weighs approximately 17.28 KGs (including stand). Without stand, it weighs 16.92 Kgs.
