The 85U7G AU is a 85 inch 4K TV from Hisense, launched in the year 2021. It features a 10-bit VA panel with Anti-glare/Matte finish.
The max. resolution it can display is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 52 ppi.
Picture Quality
After screen size and resolution, the next most important feature of a display is its Color Reproduction Accuracy, which is 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.
Now, since the TV features a big 85 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. The color quality on this TV should be Lifelike! Meaning it will produce color accurate images out of the box.
What Color Gamut means ?
Color gamut specification of a display is the measurement of the range of colors that the display can produce.
In other words, it determines the ability of a display to produce accurate colors. A TV with low gamut coverage will miss out on some colors (such as deep red), so the image produced will look "washed out" in colors.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 Adobe RGB, rec.2020.
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, you should look at the static contrast specification as it influences the picture quality substantially.
Understanding the static contrast ratio
There are two types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio as dynamic doesn't matter much.
Static contrast tells the intensity of black levels. That is, a TV with SC ratio < 1000:1 may produce black images something like this:

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

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, 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.
This TV features a static contrast ratio of 8000:1., enough to display deep blacks. For the record, it also comes with local dimming technology which is a plus.
HDR is also supported on this TV in form of Dolby Vision, HDR10 and HLG (Hybrid Log Gamma).
As for brightness, it can go as bright as 250 nits. The backlight used on the panel is Direct LED (Full-Array Local Dimming).
Gaming Performance
If you are planning to use your TV only for content consumption, you can ignore these specs. But if you are also planning to use the TV for gaming or use it as a PC monitor, you would want to get a TV with the lowest input lag and response time.
Unfortunately, there is no specification for input lag on this TV. Now, since this is not a cheap TV from Hisense, we can expect an input lag of less than 20ms.
Understanding Input lag and response time
This lag is the latency at which your key-presses or mouse movements changes the content of the screen. For casual Non-FPS games, input lag doesn't matter much.
But ideally, look for a TV that comes with an input lag and response time of < 20ms.
Ergonomics and Dimensions
Now, speaking of ergonomics — a VESA mount with interface size of 800x400 mm is provided for wall-mounting. Swivel, Tilt or Pivot features are not supported on this unit.
The width of this TV is 74.8 inches while its height is 46.85 inches.
Speaking of thickness, it is just 3.31 inches thick.
It weighs approximately 50.5 KGs and 0.8 kgs extra if you include stand.
Hardware and Audio
The chipset of this TV is powered by Quad Core (2x ARM Cortex-A73 + 2x ARM Cortex-A52) CPU while its graphics engine is handled by a (ARM Mali-G51) GPU.. However, we could'nt find any information on the RAM on the TV's official specsheet.
To power its UI, the TV runs VIDAA U5.0 Operating System.
For display connectivity, Hisense has provided four HDMI 2.0 (CEC) ports and one AV Composite In (Video + L/R) port on this TV.
For connecting USB devices, it includes 1x USB 2.0 and 1x USB 3.0. Other connectivity ports include — 1x Cable/Antenna In (F-type female) and 1x Ethernet RJ45.
For connecting to this TV wirelessly, the manufacturer has provided Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct and Bluetooth 5.0.
Now, speaking of speakers, it is packaged with 4 x 15W speakers.
Now, coming to power consumption, on average, it uses about 210W. On standby, it uses 0.5 W.
It supports a power outlet of 100 V - 120 V/50 Hz - 60 Hz.
