ABOUT THIS TV

Samsung QN43LS03B 400x400 Image Samsung QN43LS03B

The QN43LS03B is a 43 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 103 ppi.

Picture Quality

After screen size and resolution, the very next spec of a display that will impact your viewing experience is its Color Gamut.

The Samsung QN43LS03B features 100% DCI P3 color gamut coverage — equivalent to 136.36% sRGB coverage. The color quality on this TV should be Lifelike!

Understanding the Color Gamut Specification

Color gamut specification of a display indicates the range of colors that the TV can display.

Put Simply, it indicates the ability of a display to produce accurate colors. A panel with low 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,sRGB (standard RGB), NTSC, DCI P3 to name a few. It is upto the manufacturer which one they choose.

In case of this TV, it is specified using DCI P3.

But don't worry, below 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 has equally important role in picture quality.

Understanding the static contrast ratio of a TV

A TV with high enough static contrast ratio will produce natural deep blacks while a TV with low contrast ratio (<1000:1) will produce images that look muddy as shown below.

Example of a display with low contrast ratio

As you see, this will rob your experience considerably.

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.

If given a choice, I will 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., well enough to display deep blacks and eye-catching visuals. For the record, it also comes with local dimming technology which is a plus.

HDR10, HDR10+, HDR10+ Adaptive, HDR10+ Gaming, HLG (Hybrid Log Gamma) and Quantum HDR are also supported on this TV.

As for brightness, it can go as bright as 250 nits. The backlight used on the panel is Edge LED.

Gaming Performance

If you are going to use your TV other than using it as a TV — say as a PC monitor or Gaming, make sure to get a TV that features the lowest input lag. For gaming, both input lag and response time impacts the performance.

Sadly, we cannot find the input lag specification for this unit. But as this is not a cheap TV, input lag on this TV could be 20ms or below.

Understanding Input lag and response time

This lag is the amount of time at which your key-presses or mouse movements changes the content of your display. 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 has an input lag and response time of less than 20ms.

Ergonomics and Dimensions

Speaking of ergonomics — a VESA mount with interface size of 200 x 200 mm is provided for wall-mounting. The TV comes with Swivel feature, but there is no support for Tilt or Pivot.

Vertically, the TV measures 43 inches and horizontally 38.2 inches. Coming to thickness, it is 1 inches thick.

It weighs approximately 8.62 Kgs and an additional 0.27 kgs including stand.
