ABOUT THIS TV

Samsung QN50LS03B 400x400 Image Samsung QN50LS03B

The QN50LS03B is a 50 inch 4K TV from Samsung, launched in the year 2022. It comes with a 10-bit VA panel with Anti-glare/Matte finish.

It can achieve a max resolution of 3840 x 2160 @ 60 Hz with a pixel density of 89 ppi.

Picture Quality

After screen size and resolution, the next important specification to look for in a display is its Color Reproduction, which is defined by its color gamut specification.

This TV comes with a DCI P3 color gamut coverage of 100%. FYI, this is equivalent to 136.36% sRGB coverage. The color quality on this TV will be Lifelike!

Understanding the Color Gamut Specification

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

A panel with poor color reproduction will produce undersaturated/washed out colors that will spoil the immersion.

It is specified in different units - sRGB(most popular), NTSC, DCI P3 to name a few. It is upto the manufacturer which one they choose.

In case of this TV, its color gamut is specified in 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

Other than color accuracy, the static contrast specification of a TV holds almost equal role in picture quality.

Understanding the static contrast ratio of a TV

A TV with low static contrast ratio will not produce deep blacks and may bleed backlight as shown in the below image:

Backlight bleed exampleThe image is an example of another display, it is not this one

The static contrast ratio of above TV is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. More the better.

Also, 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, always 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., enough to produce deep blacks and eye-catching visuals. The panel 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.

Coming to brightness, it is capable of producing a maximum brightness of 250 nits, powered by Edge LED backlight.

Gaming Performance

If you are planning to use your TV only for content consumption, 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, you would want to get a TV that features the lowest input lag and response time.

Unfortunately, Samsung did not specify the input lag on this unit. But since this is not a cheap TV, 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 device inputs changes the content of the screen. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.

But ideally, get a TV that features an input lag and response time of less than 20ms.

Dimensions and Ergonomics

Vertically, the TV measures 50 inches and horizontally 44.3 inches.

Coming to thickness, it is just 1 inches thick. It weighs around 11.79 kgs, another 0.41 kgs if you include stand.

Now, speaking of 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 this TV is powered by a Quad Core CPU. However, we could'nt find any specification about the available RAM on this TV.

Speaking of OS, the Samsung QN50LS03B runs Tizen 6.5 Operating System.

For display connectivity, Samsung has provided four HDMI 2.0 ports on this TV.

To connect USB devices, you will have two USB 2.0 ports. Other connectivity ports include — 1x Cable/Antenna In (F-type female), 1x RS232 (C) and 1x Ethernet RJ45.

For wireless connectivity, you will have — Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth and DLNA.

Speaking of power consumption, on average, it consumes about 70 Watts. On standby, it uses 0.5 Watts.

For powering this unit, you'll require an 100 V - 120 V/50 Hz - 60 Hz outlet.
