The 32H4G is a 32 inch HD TV from Hisense. It was launched in 2021. It comes with a True 6-bit IPS panel with Anti-glare/Matte finish.
The maximum resolution it can achieve is 1366 x 768 @ 60 Hz with a pixel density of 49 ppi.
Picture Quality
After screen size and resolution, the next most important feature to look for in a display is its Color Reproduction Accuracy (defined by its color gamut specification).
This TV doesn't come with a color gamut specification, so we have to take a guess. This unit comes with an IPS panel. These panels are known to produce great colors by default. So we can assume the sRGB coverage (equivalent) on this TV to be 70% or above. For content consumption and gaming, you may not need any better than this anyway. So its good enough.
What is Color gamut ?
Color gamut spec of a TV is the measurement of the range of colors that the TV can display.
What this means is, it determines the ability of a TV to produce accurate colors. A TV with low color 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(most popular), NTSC, DCI P3 etc.
But you don't need to worry about that, below is a chart that you can use to choose a TV with good color accuracy.
Now, next in the list of important specifications is Static Contrast.
Understanding the static contrast ratio of a TV
A TV with low static contrast ratio will not produce deep enough blacks and possibly can bleed backlight as in the images below:

The above TV's static contrast is 800:1. So make sure you get a TV with a static contrast of >= 1000:1. More the better.
Think of static contrast as another dimension to details — just like resolution. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, thus lesser detail overall.
There's no mention of this spec in the TV's official specsheet. Once again we have to take a guess. FYI — IPS panels come with a static contrast ratio between 700:1 - 1500:1. For a TV launched in 2021, we can guess the ratio of Hisense 32H4G would be >= 1200:1.
As for brightness, it is can achieve a peak luminance of 250 nits. The backlight of this TV is powered by Direct LED technology.
Gaming Performance
If you aren't into gaming, you can safely 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 take a TV that features the lowest input lag and response time.
Sadly, we cannot find the input lag specification for this unit. Now, IPS panels in general come with high input lags and response times. So, expect the input lag to be above 20ms. Though, there's no concern for playability of casual or Non-FPS games on it.
What is Input lag ?
This lag is the amount of time at which key-presses or mouse movements changes the content of the TV. For casual Non-FPS games, input lag doesn't matter much.
For best of both worlds, look for a TV that features 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 200 x 200 mm. The unit doesn't come with either Swivel, Tilt or Pivot support.
The TV measures 32 inches vertically and 28.3 inches horizontally.
It is just 3.4 inches thick.
It weighs around 3.7 kilograms and an additional 0.11 kgs if you include stand. So plan your space accordingly.
Hardware and Audio
To power its UI, the TV runs Roku TV Operating System.
For display connectivity, Hisense has provided one AV Composite In (Video + L/R) port and three HDMI (ARC; CEC) ports on this TV.
For connecting USB devices, you will have one USB 2.0 port. Other connectivity ports include one Cable/Antenna In (F-type female) port.
For connecting to this TV wirelessly, you will have — Wi-Fi (5Ghz + 2.5Ghz) and Wifi-Direct.
The Audio unit of this TV is powered by 2 x 6W built-in speakers.
Speaking of power usage, on average, this TV uses 80 Watts and on standby, it takes 0.5 Watts.
For powering this unit, you will need an 100 V - 120 V/50 Hz - 60 Hz outlet.
