Samsung QE50LS03B 400x400 Image Samsung QE50LS03B

The QE50LS03B is a 50 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 @ 60 Hz with a pixel density of 89 ppi.

Picture Quality

Now, the next important spec of a display that defines picture quality is its Color Gamut.

The Samsung QE50LS03B is rated with a 100% DCI P3 color gamut coverage, which is equivalent to 136.36% sRGB. The color quality on this TV should be Lifelike!

What Color Gamut means ?

Color gamut specification of a display is a measure of the range of colors that the display can display.

A display with poor color accuracy will produce undersaturated/washed out colors that will spoil your immersive experience.

Different manufacturers use different measurement standards to specify color gamut. Viz — sRGB (standard RGB), NTSC 1953, DCI P3 Adobe RGB and rec.2020.

For example, the color gamut of this TV is specified using DCI P3.

But you don't need to worry about that, here is a chart that will help you choosing a TV with good color accuracy.

Color Gamut Chart

After color gamut, the static contrast of a TV also impacts its picture quality.

What is Static Contrast ?

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. Apart from this, such displays may suffer from backlight bleeds such as below:

Clearly this will rob your experience, especially in a dark room.

Also, a TV with high constrast ratio enables you to see more details. So, resolution and static contrast ratio go hand in hand.

If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.

This TV comes with a static contrast ratio of 8000:1., good enough to produce deep blacks. For the record, it also comes with local dimming 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 can produce a peak brightness of 250 nits with the help of Edge LED backlight.

Gaming Performance

If you are planning to use your TV other than using it as a TV — say as a PC monitor or for gaming purposes, you would want to take a TV that features the lowest input lag. For gaming however, both input lag and response time affects the performance.

Sadly, there is no specification for input lag on this TV. Now, as this is not a cheap TV, input lag on this TV could be 20ms or below.

What is Input lag ?

This lag is the latency 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, look for a TV that comes with an input lag and response time of < 20ms.

Dimensions and Ergonomics

The TV measures 50 inches vertically and 44.3 inches horizontally. Coming to thickness, it is just 1 inches thick. It weighs around 11.79 kilograms, another 0.41 kgs including stand.
