Launched in the year 2021, the 65A85G is a 65" 4K TV from Hisense. It comes with a True 10-bit OLED panel with Anti-glare/Matte finish.
The maximum resolution it can achieve is 3840 x 2160 with a refresh rate of 120 Hz and a pixel density of 68 ppi.
Picture Quality
After screen size and resolution, the next important feature of a display is its Color Reproduction Accuracy, which is defined by its color gamut specification.
Speaking of which, this TV is rated with a 97% DCI P3 color gamut coverage, which is equivalent to 132.27% sRGB coverage. The color accuracy on this TV will be Lifelike!
What Color Gamut means ?
Color gamut specification of a TV is the measurement of the range of colors that it can show.
What this means is, it determines the ability of a display to produce accurate colors. A display with low gamut coverage will miss out on some colors (such as deep red), thus producing a "washed out" picture.
It is specified in different units - sRGB(most popular), NTSC 1953, DCI P3 to name a few. It is upto the manufacturer which one they choose.
In case of this TV, its color gamut is specified in DCI P3.
But don't worry, here is a chart that you can use to choose a TV with good color accuracy.
Other than color accuracy, you should look at the static contrast specification as it impacts the picture quality the same way.
Understanding the static contrast ratio of a TV
There are 2 types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio. Dynamic doesn't matter much.
Static contrast specification defines the intensity of black levels. That is, a TV with SC ratio less than 1000:1 may produce black images something like this:

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

Also, 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 show both dark gray and black as black, so lesser detail overall.
For a display with OLED panel, its static constrast will be Infinity : 1. So no need to worry about this at all.
HDR is also supported on this TV in form of HLG (Hybrid Log Gamma), HDR10+, HDR10 and Dolby Vision.
Coming to brightness, it is can produce a peak luminance of 800 nits.This amount of brightness is good enough even for a room with sun's rays in!
Gaming Performance
If you are not into gaming, you can ignore these specifications. But if you are also going to use the TV for playing games or use it as a PC monitor, make sure to get a TV with the lowest input lag and response time.
The input lag on this TV is 20 ms and its minimum response time is 1 ms. It is good enough for casual and non-FPS games but is not suitable for competitive or FPS gameslike CSGO.
Understanding Input lag and response time
This lag is the amount of time at which your device inputs changes the content of the TV. For casual Non-FPS games, input lag doesn't matter much.
Although for better experience, get a TV that features an input lag and response time of < 20ms.
Ergonomics and Dimensions
Coming to ergonomics — VESA mount is supported on this TV with an interface size of 300 x 200 mm. Tilt or Pivot are not supported on this TV, but it does support Swivel.
The TV measures 65 inches vertically and 57.75 inches horizontally. It weighs around 17.5 kilograms. So plan your space accordingly.
Hardware and Audio
The TV is powered by 4-Core (2x ARM Cortex-A73 + 2x ARM Cortex-A52) CPU and its graphics engine is handled by a (ARM Mali-G51) GPU.. However, Hisense didn't provide any specification on the total RAM on the TV's specsheet.
To power its UI, the TV runs VIDAA U5.0 Operating System.
For display connectivity, there are four HDMI 2.0 (CEC) ports and one AV Composite In 3.5 mm jack port on this TV.
For connecting USB devices, it includes 1x USB 2.0 and 1x USB 3.0. Other connectivity ports include — 1x Satellite In (F-type female), 1x Antenna (RF) (female), 1x CI+ 1.4 and 1x Ethernet RJ45 (100 Mbps).
Wireless connectivity options on this TV include a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct and Bluetooth 5.0.
Coming to audio, Hisense has provided 4 x 10W speakers on the 65A85G.
Now, coming to power usage, the TV consumes 114.24 watts on average and 0.5 watts on standby.
Both 110V and 220V outlets are supported on this unit.
