Launched in the year 2022, the QE75Q70B is a 75" 4K TV from Samsung. It comes with a 10-bit VA panel with Anti-glare/Matte finish.
The maximum resolution it can display is 3840 x 2160 with a refresh rate of 120 Hz and a pixel density of 59 ppi.
After screen size and resolution, the very next spec of a display that will impact your viewing experience is its Color Gamut.
The Samsung QE75Q70B features 100% DCI P3 color gamut coverage. FYI, this is equivalent to 136.36% sRGB coverage. The color quality on this TV should be Lifelike!
Understanding the Color Gamut Specification
Color gamut spec of a display is the measurement of the range of colors that the display can display.
Put Simply, it tells the ability of a TV to produce accurate colors. A TV with low 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 units to specify color gamut. Viz — sRGB (most popular), NTSC, DCI P3 to name a few.
For example, the color gamut of this TV is specified in terms of DCI P3.
But don't worry, below is a chart that will help you choosing a TV with good color accuracy.
Now, next in the list of important specifications that will impact your experience is Static Contrast.
Understanding the static contrast ratio of a TV
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. Also, such TVs often suffer from backlight bleeds such as below:The image is an example of another display, it is not this one
Needless to say, this will affect your viewing experience, especially in a dark room.
Other than black levels, a TV with high constrast ratio allows you to see more details. So, resolution and static contrast ratio go hand in hand in a sense.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV features a static contrast ratio of 8000:1., good enough to display deep blacks. The panel comes with local dimming backlight technology which is a plus.
HDR is also supported on this TV in form of HDR10, HLG (Hybrid Log Gamma), HDR10+, HDR10+ Adaptive, HDR10+ Gaming and Quantum HDR.
As for brightness, it is can achieve a maximum brightness of 250 nits with the help of Edge LED backlight.
If you are planning to use your TV solely for content consumption, you can ignore these specifications. But if you are also going to use the TV for gaming or use it as a PC monitor, make sure to get a TV with the lowest input lag and response time.
Sadly, there is no specification for input lag on this TV. But as this is not a cheap TV, we can expect an input lag of less than 20ms.
Understanding Input lag and response time
This lag is the latency at which your device inputs changes the content of the screen. For casual Non-FPS games, input lag doesn't matter much.
But ideally, get a TV that comes with an input lag and response time of < 20ms.
Ergonomics and Dimensions
Now, speaking of ergonomics — a VESA mount with interface size of 400 x 400 mm is provided for wall-mounting. The unit doesn't come with either Swivel, Tilt or Pivot support.
The TV measures 75 inches vertically and 66 inches horizontally. Coming to thickness, it is just 1 inches thick.
Overall this TV weighs 34.7 KGs including its stand. Without stand, it weighs 33.4 kgs. So plan your space accordingly.
