The 43A7200G is a 43 inch 4K TV from Hisense. It was launched in 2021. It comes with a 10-bit IPS panel. It can display a maximum resolution of 3840 x 2160 @ 60 Hz with a pixel density of 103 ppi.
Picture Quality
After screen size and resolution, the next 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, but don't worry, we have other means to guess that.
Considering the TV comes with a 10bit IPS panel, we can safely assume its equivalent sRGB coverage to be 100% or above. The color accuracy on this TV should be Lifelike!
What Color Gamut means ?
Color gamut spec of a TV is a measure of the range of colors that it can produce.
A panel with poor color accuracy will produce washed out colors that will not be pretty to look at.
It is specified in different units - sRGB(most popular), NTSC, DCI P3 Adobe RGB, rec.2020. It is upto the manufacturer which one they choose.
But you don't need to worry about that, 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 has equally important role in picture quality.
Understanding the static contrast specification
Static contrast ratio of a TV corresponds to its Black levels. A Display with low static contrast ratio (less than 1000:1) will not produce deep blacks. Also, such TVs may suffer from backlight bleeds such as this:

Needless to say, this will impact your experience considerably, especially in a dark room.
Note that, static contrast ratio and resolution go hand in hand when it comes to details. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, thus lesser detail overall.
If given a choice, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
There's no mention of this spec in the TV's official specsheet. So we have to make an assumption again. FYI — IPS panels come with a static contrast ratio between 700:1 - 1500:1. As for a 4K TV, we can imagine the ratio to be on the upper side, that is atleast 1200:1.
HDR is also supported on this TV in form of HDR10 and HLG (Hybrid Log Gamma).
As for brightness, the peak brightness it can achieve is 250 nits. The backlight used on the panel is Direct LED.
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, make sure to get a TV that features the 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. Now, as this is not a cheap TV from Hisense, we can expect an input lag of less than 20ms.
What is Input Lag and Why it matters ?
This lag is the amount of time at which key-presses/mouse movements changes the content of your TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
But ideally, look for a TV that comes with an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Speaking of ergonomics — VESA mount is supported on this TV with an interface size of 200 x 200 mm. Swivel, Tilt or Pivot features are not supported on this unit.
The width of this TV is 38.15 inches while its height is 24.25 inches. In terms of thickness, it is just 3.35 inches thick.
Overall this TV weighs approximately 7.1 Kgs including stand. Without stand, it weighs 7.0 Kgs. So plan your space accordingly.
