Launched in the year 2022, the QЕ75LS03B is a 75" 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 59 ppi.
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 is rated with a DCI P3 color space coverage of 100%, which is equivalent to 136.36% sRGB coverage. The color accuracy on this TV should be Lifelike!
What Color Gamut means ?
Color gamut spec of a display is the measurement of the range of colors that the TV can produce.
In layman terms, this specification tells the ability of a TV to produce accurate colors. A panel with low color gamut coverage will miss out on some colors (such as deep red), so the image produced will look "washed out" in colors.
Different manufacturers use different measurement standards to define color gamut. Such as — sRGB (most popular), NTSC, DCI P3 etc.
As for this TV its color gamut is specified using DCI P3.
But don't worry, here is a chart that will help you choosing a TV with good color accuracy.
Now, after color gamut, the static contrast specification 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 Display with low static contrast ratio (<1000:1) will not produce deep blacks. Also, such displays may suffer from backlight bleeds such as this:The image is an example of another display, it is not this one
This will rob your viewing experience, especially in a dark room.
Like resolution, the static contrast ratio is also equally responsible for details. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, thus lesser detail overall.
This TV comes with a static contrast ratio of 8000:1., good enough to produce deep blacks and eye-catching visuals. The panel comes with local dimming feature 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.
Coming to brightness, the peak luminance the Samsung QЕ75LS03B can achieve is 250 nits. The backlight of this TV is powered by Edge LED technology.
If you are planning to use your TV solely for content consumption, you can safely ignore these specs. But if you are also going to use the TV for playing games or use it as a PC monitor, you should get a TV with the lowest input lag and response time.
Sadly, there is no specification for input lag on this TV. Now, since this is not a cheap TV, input lag on this TV could be 20ms or below.
What is Input lag ?
This lag is the amount of time at which key-presses or mouse movements changes the content of the TV. For casual Non-FPS games, input lag doesn't matter much.
But ideally, look for a TV that comes with an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Coming to ergonomics — VESA mount is supported on this TV with an interface size of 400 x 400 mm. Tilt or Pivot are not supported on this TV, but it does support Swivel.
The width of this TV is 66.2 inches while its height is 39.3 inches.
Coming to thickness, it is 1.1 inches thick.
Overall this TV weighs 35.88 kgs (including stand). Without stand, it weighs 35.29 kgs. So plan your space accordingly.

The Operating System on this TV is Tizen 6.5.
For display connectivity, Samsung has provided three HDMI 2.0 ports and one HDMI 2.1 port on this TV.
