Launched in the year 2022, the UE70BU8000 is a 70" 4K TV from Samsung. It comes with a 10-bit VA panel.
It can achieve a maximum resolution of 3840 x 2160 with a refresh rate of 60 Hz and pixel density of 63 ppi.
After screen size and resolution, the next most important specification of a display is its Color Reproduction Accuracy (defined by its color gamut specification).
This TV doesn't provide a color gamut specification, so we have to take a guess. 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. Undoubtedly The color accuracy on this TV will be Lifelike! Meaning it is capable of producing color accurate images AS IT IS intended.
Understanding the Color Gamut Specification
Color gamut specification of a display is a measure 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 color gamut coverage will miss out on some colors (such as deep red), thus producing a "washed out" picture.
Different manufacturers use different units to specify color gamut. Such as — sRGB, NTSC 1953, DCI P3 etc.
But you don't need to worry about that, here is a chart that will help you choosing a TV with good color accuracy.
Other than color accuracy, the static contrast specification of a TV has equally important role in picture quality.
What is Static Contrast ratio ?
A TV with low static contrast ratio will not produce deep enough blacks and possibly can bleed backlight as in the below image:The image is an example of another display, it is not this one
The static contrast ratio of above TV is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. More is better.
Like resolution, the static contrast ratio is also equally responsible for details. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, so 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 achieve deep blacks and eye-catching visuals. 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.
As for brightness, it is capable of producing a peak luminance of 250 nits, powered by Edge LED backlight.
If you aren't into gaming, you can safely ignore these specifications. But if you are also planning to use the TV for gaming or use it as a PC monitor, you should get a TV that features the lowest input lag and response time.
The input lag on the Samsung UE70BU8000 is 8 ms and its minimum response time is N/A. For a TV, its the best you can get for gaming.
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. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
But ideally, get a TV that comes with an input lag and response time of < 20ms.
Dimensions and Ergonomics
The vertical and horizontal measurements of this TV are 62 inches and 36.34 inches respectively. It is just 1 inches thick.
In total it weighs 28.0 kilograms including stand. Without stand, it weighs 27.4 kgs.
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.
Hardware and Audio
The core of Samsung UE70BU8000 is powered by a Quad Core CPU. However, Samsung didn't provide any info on the total RAM on the TV's 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.
To connect USB devices, you will have two USB 2.0 ports. Other connectivity ports include — 1x Satellite In (F-type female), 1x Antenna (RF) (female), 1x CI+ 1.4 and 1x Ethernet RJ45.
Wireless connectivity options on the Samsung UE70BU8000 include Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth and DLNA.
For audio, it is packaged with 2 x 10W speakers.
Speaking of power consumption, the TV consumes 140W on average and 0.5W on standby.
Both 110V and 220V outlets are supported on this unit.
