The UN70BU8000 is a 70 inch 4K TV from Samsung, launched in the year 2022. It comes with a 10-bit VA panel. The maximum resolution it can achieve is 3840 x 2160 @ 60 Hz with a pixel density of 63 ppi.
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, but don't worry, we have other means to guess that.
Now, since the TV features amassive 70 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! It is capable of producing accurate colors by default.
Understanding the Color Gamut Specification
Color gamut specification of a display is the measurement of the range of colors that it can show.
A TV with poor color reproduction will produce washed out colors that will spoil your immersive experience.
Different manufacturers use different measurement standards to specify color gamut. Such as — sRGB (most popular), NTSC 1953, DCI P3 etc.
But don't worry, here is a chart that will help you choosing a TV with good color accuracy.
Other than color accuracy, the static contrast ratio of a TV holds almost equal role in picture quality.
Why its important?
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 below.
As you imagine, this will impact 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, so lesser detail overall.
This TV comes with a static contrast ratio of 8000:1., good enough to produce deep blacks and eye-catching visuals. The panel comes with local dimming backlight which is a plus.
HLG (Hybrid Log Gamma), HDR10+, HDR and HDR10 are also supported on this TV.
As for brightness, it is capable of producing a maximum luminance of 250 nits, which is powered by Edge LED backlight.
Now if you are planning to use a TV other than using it as a TV — like as a PC monitor or for gaming purposes, you should get a TV that features the lowest input lag. For gaming, both the input lag and response time affects the performance.
The input lag on this TV is 8 ms and its minimum response time is N/A. Pick this one if you are a gamer.
Understanding Input lag and response time
This lag is the latency 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, look for a TV that features an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Now, speaking of ergonomics — a VESA mount with interface size of 400 x 300 mm is provided for wall-mounting. The unit doesn't come with Swivel, Tilt or Pivot support.
Vertically, the TV measures 70 inches and horizontally 62 inches. Speaking of thickness, it is just 1 inches thick.
Overall it weighs around 28.0 KGs including stand. Without stand, it weighs 27.4 Kilograms.
Hardware and Audio
The TV comes with a 4-Core CPU. However, Samsung didn't provide any specification about the total RAM on the TV's official specsheet.
The Operating System on this TV is Tizen 6.5.
For display connectivity, Samsung has provided three HDMI 2.0 ports on this TV.
To connect USB devices, you will have two USB 2.0 ports. Other connectivity ports include — 1x Cable/Antenna In (F-type female), 1x RS232 (C) and 1x Ethernet RJ45.
For wireless connections, you will have — Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth and DLNA.
Now, for audio, it is packaged with 2 x 10W speakers.
In terms of power consumption, the TV consumes 156.72 Watts on average and 0.5 Watts on standby.
It supports a power outlet of 100 V - 120 V/50 Hz - 60 Hz.
