The 50R7G5 is a 50 inch 4K TV from Hisense, launched in the year 2021. It comes with a 10-bit VA panel with Anti-glare/Matte finish.
It can achieve a maximum resolution of 3840 x 2160 @ 60 Hz with a pixel density of 89 ppi.
Picture Quality
After screen size and resolution, the next most important specification to look for in a display is its Color Reproduction (defined by its color gamut specification).
This TV doesn't come with a color gamut specification, so we have to take a guess.
Considering the TV features a big 50 inch screen, it won't come with a cheap panel, so here we can assume its equivalent sRGB coverage to be 90-100% or above. Undoubtedly The color quality on this TV will be Lifelike! It will produce accurate colors by default.
Understanding Color Gamut
Color gamut spec of a TV is a measure of the range of colors that the TV can display.
Meaning, this specification 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), the result would be a "washed out" picture quality.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 etc.
But you don't need to worry about that, below is a chart that will help you choosing a TV with good color accuracy.
Now, after color gamut, the static contrast of a TV also impacts its picture quality.
What is Static Contrast ?
There are 2 types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio as dynamic doesn't matter much.
Static contrast specification tells the intensity of black levels. That is, a TV with SC ratio less than 1000:1 will produce black images something like this:

Apart from this, such TVs are likely be prone to backlight bleeds that will affect your experience — as shown below.

Also, a TV with high constrast ratio enables you to see more details. So, resolution and static contrast ratio go hand in hand.
There's no mention of this specification in this TV's official specsheet. So once again we have to make an assumption based on the TV's other specs. VA panels usually have superior contrast ratios. As you know, this TV features the same, so the static contrast ratio would be easily atleast 3000:1 or above.
HDR10, HLG (Hybrid Log Gamma) and Dolby Vision are also supported on this TV, so that's a plus.
Coming to brightness, the peak brightness it can produce is 250 nits, which is powered by Direct LED backlight.
Gaming Performance
Now if you are planning to use a TV other than using it as a TV — like as a PC monitor or Gaming, you would want to take a TV with lowest input lag. For gaming however, both input lag and response time impacts the performance.
Sadly, there is no specification for input lag on this TV. But as 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/mouse movements changes the content of the TV. For casual Non-FPS games, input lag doesn't matter much.
Although for better experience, look for a TV that comes with an input lag and response time of < 20ms.
Ergonomics and Dimensions
Now, coming to ergonomics — VESA mount is supported on this TV with an interface size of 300 x 200 mm. There is no Swivel, Tilt or Pivot feature support on this TV.
The TV measures 50 inches vertically and 43.98 inches horizontally.
It is just 2.91 inches thick. Overall this TV weighs 10.0 KGs including stand. Without stand, it weighs 9.8 KGs. So plan your space accordingly.
