Launched in the year 2021, the 50H8G1 is a 50" 4K TV from Hisense. It features a True 10-bit VA panel. The maximum resolution it can display is 3840 x 2160 @ 60 Hz with a pixel density of 89 ppi.
Picture Quality
Now, the very next spec of a display that impacts picture quality is its Color Gamut.
This TV doesn't come with a color gamut specification, so we have to make an assumption based on its panel type. Considering the TV features a 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 accuracy on this TV should be Lifelike! It will produce accurate colors.
What Color Gamut means ?
Color gamut specification of a display is a measure of the range of colors that the display can show.
A display with poor color accuracy will produce washed out colors that will not be pretty to look at.
Different manufacturers use different units to define color gamut. Such as — sRGB (most popular), NTSC, DCI P3 Adobe RGB and rec.2020.
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.
Now, after color gamut, the static contrast of a TV similarly impacts its picture quality.
The importance of static contrast ratio
There are two types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio. Dynamic doesn't matter much.
This specification tells the intensity of black levels. That is, a TV with static contrast ratio < 1000:1 may produce black images something like this:

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

Also, 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 produce deep blacks and eye-catching visuals. For the record, it also comes with local dimming backlight technology which is a plus.
HDR10, HDR10+, HLG (Hybrid Log Gamma) and Dolby Vision are also supported on this TV.
Coming to brightness, the peak brightness it can achieve is 700 nits. The backlight of this TV is powered by Direct LED (Full-Array Local Dimming) technology. This amount of brightness is good enough even for a well-lit room!
Gaming Performance
If you are planning to use your TV solely 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 take a TV that features the lowest input lag and response time.
Unfortunately, Hisense did not specify the input lag on this unit. 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 amount of time at which your inputs changes the content of your display. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
Although for better experience, look for a TV that comes with an input lag and response time of < 20ms.
Ergonomics and Dimensions
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 300 x 200 mm. The unit doesn't come with either Swivel, Tilt or Pivot support.
Vertically, the TV measures 50 inches and horizontally 43.8 inches. It is 3.1 inches thick. It weighs approximately 12.79 kilograms and an additional 0.21 kgs including stand.
