Launched in the year 2022, the UN85BU8000 is a 85" 4K TV from Samsung. It comes with a 10-bit VA, IPS-ADS panel.
The max. resolution it can achieve is 3840 x 2160 @ 60 Hz with a pixel density of 52 ppi.
After screen size and resolution, the next most important spec to look for in a display is its Color Reproduction, which is defined by its color gamut specification.
Samsung did not provide a color gamut specification for this TV. So we have to take a guess.
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 is Color gamut ?
Color gamut specification of a display is the measurement of the range of colors that the TV can display.
Meaning, this specification tells the ability of a display to produce accurate colors. A display with low color gamut coverage will miss out on some colors (such as deep red), so the image produced will look "washed out" in colors.
Different manufacturers use different measurement standards to define color gamut. Viz — sRGB (standard RGB), NTSC 1953, DCI P3 Adobe RGB and rec.2020.
But don't worry, below is a chart that you can use to choose a TV with good color accuracy.
Other than color accuracy, the static contrast ratio of a TV has equally important role in picture quality.
Understanding the static contrast ratio of a TV
A TV with high enough static contrast ratio will produce deep blacks while a TV with low contrast ratio (<1000:1) will produce images that look dusty as shown in the below image.
As you can see, this will rob your experience considerably.
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 show both dark gray and black as black, thus lesser detail overall.
If given a choice, always 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., good enough to produce deep blacks. The panel comes with local dimming feature which is a plus.
HLG (Hybrid Log Gamma), HDR10+, HDR and HDR10 are also supported on this TV, so that's a plus.
Coming to brightness, the peak luminance it can achieve is 250 nits. The backlight used on the panel is Edge LED.
If you are planning to use the TV other than watching videos — like as a PC monitor or Gaming, you should get a TV with lowest input lag. For gaming however, both the input lag and response time impacts the performance.
The input lag on this TV is 8 ms and its minimum response time is N/A. You will love this TV if you are a gamer.
Understanding Input lag and response time
This lag is the amount of time at which your device inputs 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, get a TV that comes with an input lag and response time of less than 20ms.
Dimensions and Ergonomics
The vertical and horizontal measurements of this TV are 74.84 inches and 44.45 inches respectively. It is 1 inches thick.
It weighs around 41.5 kgs and 1.0 kgs extra including stand.
Coming to ergonomics — VESA mount is supported on this TV with an interface size of 600 x 400 mm. Swivel, Tilt or Pivot features are not supported on this unit.

The core of Samsung UN85BU8000 is powered by a 4-Core CPU. However, Samsung didn't provide any information about the total RAM on the TV's official specsheet.
To power its UI, the TV runs Tizen 6.5 Operating System.
For display connectivity, Samsung has provided three HDMI 2.0 ports on this TV.
For connecting USB devices, it includes two USB 2.0 ports. Other connectivity ports include — 1x Cable/Antenna In (F-type female), 1x RS232 (C) and 1x Ethernet RJ45.
For connecting to this TV wirelessly, the manufacturer has provided Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth and DLNA.
The Audio unit of this TV is powered by 2 x 10W built-in speakers.
Now, coming to power consumption, this TV uses 158.16 watts on average and 0.5 watts on standby.
