Launched in the year 2022, the OLED55B2PUA is a 55" 4K TV from LG. It comes with a True 10-bit OLED panel. It can achieve a max resolution of 3840 x 2160 @ 120 Hz with a pixel density of 80 ppi.
Picture Quality
After screen size and resolution, the next most important feature to look for in a display is its Color Reproduction Accuracy (defined by its color gamut specification).
LG has not provided a color gamut rating for this TV. But don't worry, we have other means to guess that. Since the TV features an OLED panel, so we can conclude that the equivalent sRGB coverage of this TV would be far above 100%.
What is Color gamut ?
Color gamut specification of a TV is the measurement of the range of colors that the TV can produce.
In layman terms, this specification determines the ability of a display to produce accurate colors. A panel with low color gamut coverage will miss out on some colors (such as deep red), thus producing a "washed out" picture.
It is specified in different units - sRGB(most popular), NTSC, DCI P3 etc. It is upto the manufacturer which one they choose.
But don't worry, below is a chart that you can use to choose a TV with good color accuracy.
Now, next in the list that will impact your experience is Static Contrast.
What is Static Contrast ?
A TV with low static contrast ratio will not produce deep blacks and possibly bleed backlight as shown in the images below:

The above TV's static contrast is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. More is better.
Also, 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 produce less shades of colors, so lesser detail overall.
For a display with OLED panel, its static constrast will be Infinity : 1. So no need to worry about this.
HLG (Hybrid Log Gamma), Dolby Vision, Dolby Vision IQ and HDR10 Pro are also supported on this TV, so that's a plus.
As for brightness, it is can produce a maximum brightness of 250 nits.
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 playing games or use it as a PC monitor, make sure to get a TV that features the lowest input lag and response time.
The input lag on the LG OLED55B2PUA is 5 ms and its minimum response time is 1 ms. For a TV, its the best you can get for gaming.
What is Input Lag and Why it matters ?
This lag is the amount of time 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 comes with an input lag and response time of less than 20ms.
Dimensions and Ergonomics
The TV measures 55 inches vertically and 48.35 inches horizontally. It is just 1.85 inches thick. Overall it weighs around 19.9 KGs including stand. Without stand, it weighs 18.9 KGs.
