Launched in the year 2022, the 50E7HQ is a 50" 4K TV from Hisense. It comes with a 10-bit VA panel with Anti-glare/Matte finish.
It can display a max resolution of 3840 x 2160 @ 120 Hz with a pixel density of 89 ppi.
Picture Quality
After screen size and resolution, the next most important specification of a display is its Color Reproduction Accuracy (defined by its color gamut specification).
Speaking of which, this TV features a DCI P3 color space coverage of 95%. FYI, this is equivalent to 129.55% sRGB. The color accuracy on this TV should be Lifelike!
Understanding Color Gamut
Color gamut spec of a TV is the measurement of the range of colors that the display can show.
Meaning, this specification tells the ability of a display to produce accurate colors. A display 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(most popular), NTSC, DCI P3 Adobe RGB, rec.2020.
For example, the color gamut of this TV is specified using DCI P3.
But you don't need to worry about that, here is a chart that you can use to choose a TV with good color accuracy.
Other than color accuracy, the static contrast specification of a TV has equally important 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. Also, such TVs often suffer from backlight bleeds such as this:

Needless to say, this will impact your 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.
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., good enough to display deep blacks. For the record, it also comes with local dimming feature which is a plus.
Dolby Vision, HDR10, HLG (Hybrid Log Gamma) and HDR10+ are also supported on this TV.
Coming to brightness, the peak luminance the Hisense 50E7HQ can achieve is 400 nits with the help of Direct LED backlight.
Gaming Performance
If you are planning to use your TV solely for content consumption, you can ignore these specs. 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 that features the lowest input lag and response time.
The input lag on the Hisense 50E7HQ is 7.7 ms and its minimum response time is 5 ms. Gamers will love this TV.
What is Input Lag and Why it matters ?
This lag is the latency at which your key-presses or mouse movements 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 comes with an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Now, speaking of ergonomics — If you plan to wall mount the TV, you can make use of the VESA mount provided with this TV, which by the way has an interface size of 200 x 300 mm. The unit doesn't come with either Swivel, Tilt or Pivot support.
The TV measures 50 inches vertically and 43.98 inches horizontally. In terms of thickness, it is just 2.91 inches thick. Overall this TV weighs around 11.4 kilograms (including stand). Without stand, it weighs 9.8 Kgs. So plan your space accordingly.
