ABOUT THIS TV

Samsung QE55LS03B 400x400 Image Samsung QE55LS03B

Launched in the year 2022, the QE55LS03B is a 55" 4K TV from Samsung. It comes with a 10-bit VA panel with Anti-glare/Matte finish. It can achieve a maximum resolution of 3840 x 2160 with a refresh rate of 120 Hz and pixel density of 80 ppi.

Picture Quality

After screen size and resolution, the very next specification of a display that impacts picture quality is its Color Gamut.

This TV comes with 100% DCI P3 color gamut coverage — equivalent to 136.36% sRGB. The color quality on this TV should be Lifelike!

What is Color gamut ?

Color gamut spec of a display is the measurement of the range of colors that the display can produce.

Meaning, it indicates the ability of a TV to produce accurate colors. A panel with low gamut coverage will miss out on some colors (such as deep red), thus producing a "washed out" picture.

It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 etc.

For example, the color gamut of this TV is specified in terms of 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 ratio of a TV holds almost equal role in picture quality.

The importance of static contrast ratio

The static contrast ratio of a TV corresponds to its Black levels. A TV with low static contrast ratio (<1000:1) will not produce deep blacks. Moreover, such displays may suffer from backlight bleeds such as this:

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

Other than black levels, a TV with high constrast ratio enables you to see more details. So, resolution and static contrast ratio go hand in hand in a sense.

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., well enough to achieve deep blacks and eye-catching visuals. The panel comes with local dimming backlight technology which is a plus.

HDR10, HDR10+, HDR10+ Adaptive, HDR10+ Gaming, HLG (Hybrid Log Gamma) and Quantum HDR are also supported on this TV, so that's a plus.

As for brightness, it can go as bright as 250 nits. The panel of this TV is powered by Edge LED backlight technology.

Gaming Performance

If you are not planning to game on this TV, 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, make sure to get a TV with the lowest input lag and response time.

Sadly, we cannot find the input lag specification for this unit. But as this is not a cheap TV, we can expect an input lag of less than 20ms.

What is Input lag ?

This lag is the amount of time at which your device inputs changes the content of your display. For casual Non-FPS games, input lag doesn't matter much.

Although for better experience, get a TV that features an input lag and response time of < 20ms.

Dimensions and Ergonomics

The width of this TV is 48.7 inches while its height is 29.3 inches. Coming to thickness, it is 1 inches thick. In total this TV weighs approximately 17.28 kilograms including its stand. Without stand, it weighs 16.92 kgs.

Coming to ergonomics — a VESA mount with interface size of 200 x 200 mm is provided for wall-mounting. Tilt or Pivot are not supported on this TV, but it does support Swivel.

Hardware and Audio

The core of Samsung QE55LS03B is powered by a Quad Core CPU. However, we could'nt find any information about the RAM on the TV's official specsheet.

Speaking of OS, the Samsung QE55LS03B runs Tizen 6.5 Operating System.

For display connectivity, there are three HDMI 2.0 ports and one HDMI 2.1 port on this TV.
