The 65H8G1 is a 65 inch 4K TV from Hisense. It was launched in 2021. It features a True 10-bit VA panel.
The maximum resolution it can achieve is 3840 x 2160 @ 60 Hz with a pixel density of 68 ppi.
Picture Quality
After screen size and resolution, the next most important spec 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 make an assumption based on its panel type. As this TV features a 65 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 will be Lifelike! Meaning it is capable of producing color accurate images AS IT IS intended.
What Color Gamut means ?
Color gamut specification of a TV is the measurement of the range of colors that the display can display.
A display with poor color accuracy will produce undersaturated/washed out colors that will spoil the immersion.
Different manufacturers use different measurement standards to specify color gamut. Such as — sRGB (most popular), NTSC 1953, DCI P3 Adobe RGB and rec.2020.
But don't worry, here is a chart that will help you choosing a TV with good color accuracy.
After color gamut, you should look at the static contrast specification as it influences the picture quality substantially.
What is Static Contrast ratio ?
The 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 displays are likely to suffer from backlight bleeds such as below:

Clearly this will impact your viewing experience, especially in a dark room.
Other than black levels, a TV with high constrast ratio allows you to see more details. So, resolution and static contrast ratio go hand in hand.
This TV is rated with a static contrast ratio of 8000:1., good enough to display deep blacks. The panel comes with local dimming backlight which is a plus.
HDR is also supported on this TV in form of HDR10, HDR10+, HLG (Hybrid Log Gamma) and Dolby Vision.
Coming to brightness, it can go as bright as 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 room with sun's rays in!
Gaming Performance
If you are planning to use the TV other than using it as a TV — say as a PC monitor or for gaming purposes, you should take a TV that features the lowest input lag. For gaming however, both the input lag and response time affects the performance.
Sadly, we cannot find the input lag specification for this unit. But as this is not a cheap TV, input lag on this TV could be 20ms or below.
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.
Although for better experience, look for a TV that has an input lag and response time of less than 20ms.
Dimensions and Ergonomics
The TV measures 65 inches vertically and 57 inches horizontally. It is just 3.1 inches thick.
In total it weighs approximately 20.0 KGs including stand. Without stand, it weighs 19.5 kgs.
Speaking of ergonomics — VESA mount is supported on this TV with an interface size of 300 x 200 mm. However, there is no Swivel, Tilt or Pivot feature support on this TV.
Hardware and Audio
Speaking of OS, the Hisense 65H8G1 runs Android 10 Operating System.
For display connectivity, there are four HDMI 2.0 (ARC; CEC) ports and one AV Composite In (Video + L/R) port on this TV.
For connecting USB devices, you will have two USB 2.0 ports. Other connectivity ports include — 1x Cable/Antenna In (F-type female) and 1x Ethernet RJ45.
Wireless connectivity options on this TV include a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct and Bluetooth.
The Audio unit of this TV is powered by 2 x 10W built-in speakers.
Speaking of power usage, on average, it consumes around 156 watts. On standby, it uses 0.5 watts.
For powering this unit, you will require either a 110V or 220V outlet @ 50Hz-60Hz.
