The UE55BU8000 is a 55 inch 4K TV from Samsung, launched in the year 2022. It features a 10-bit VA, IPS-ADS panel.
It can achieve a max resolution of 3840 x 2160 with a refresh rate of 60 Hz and pixel density of 80 ppi.
After screen size and resolution, the next important specification of a display that impacts picture quality is Color Gamut.
Samsung has not provided a color gamut specification for this TV. So we have to take a guess. As this TV features a 55 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 accuracy on this TV should be Lifelike! It will produce accurate colors AS IT IS intended.
What is Color gamut ?
Color gamut spec of a TV is a measure of the range of colors that it can display.
A display with poor color reproduction will produce undersaturated/washed out colors that will not be pretty to look at.
Different manufacturers use different units to specify color gamut. Such as — sRGB, NTSC, DCI P3 to name a few.
But don't worry, here is a chart that you can use to choose a TV with good color accuracy.
After color gamut, the static contrast of a TV also impacts its picture quality.
Why its important?
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 < 1000:1 may produce black images something like this:
Apart from this, such TVs are likely to suffer from backlight bleeds that will rob your experience — as shown below.The image is an example of another display, it is not this one
Other than black levels, a TV with high constrast ratio enables you to see more details. So, resolution and static contrast ratio go hand in hand.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV comes with a static contrast ratio of 8000:1., well enough to produce deep blacks and eye-catching visuals. For the record, it also comes with local dimming technology which is a plus.
HDR is also supported on this TV in form of HLG (Hybrid Log Gamma), HDR10+, HDR and HDR10.
As for brightness, it can go as bright as 250 nits. The backlight used on the panel is Edge LED.
If you are planning to use your TV solely for content consumption, you can safely ignore these specifications. But if you are also planning to use the TV for playing games or use it as a PC monitor, you would want to get a TV that features the lowest input lag and response time.
The input lag on the Samsung UE55BU8000 is 8 ms and its minimum response time is N/A. For a TV, its the best you can get for gaming.
What is Input lag ?
This lag is the latency at which key-presses or mouse movements changes the content of the TV. For casual Non-FPS games, input lag doesn't matter much.
For best of both worlds, look for a TV that features an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Now, speaking of ergonomics — VESA mount is supported on this TV with an interface size of 200 x 200 mm. However, there is no Swivel, Tilt or Pivot feature support in this TV.
