The OLED55B26LA is a 55 inch 4K TV from LG. It was launched in 2022. It comes with a True 10-bit OLED panel. The max. resolution it can display is 3840 x 2160 @ 120 Hz with a pixel density of 80 ppi.
Picture Quality
After screen size and resolution, the next important feature to look for in a display is its Color Reproduction Accuracy (defined by its color gamut specification).
LG did not provide 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 panel would be far above 100%.
What Color Gamut means ?
Color gamut spec of a display is a measure of the range of colors that the display can display.
What this means is, this specification indicates the ability of a display to produce accurate colors. A display with low 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 units to specify color gamut. Viz — sRGB (standard RGB), NTSC 1953, DCI P3 to name a few.
But don't worry, below is a chart that you can use to choose a TV with good color accuracy.
Now, after color gamut, the static contrast ratio of a TV holds almost equal role in picture quality.
Understanding the static contrast ratio of a TV
The static contrast ratio of a TV corresponds to its Black levels. A TV with low static contrast ratio (less than 1000:1) will not produce deep blacks. Moreover, such displays may suffer from backlight bleeds such as this:

Clearly this will impact your viewing experience considerably, especially in a dark room.
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.
For a display with OLED panel, its static constrast would 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 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 take a TV that features the lowest input lag and response time.
The input lag on the LG OLED55B26LA 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 latency at which 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.
But ideally, 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 300 x 200 mm is provided for wall-mounting. There is no Swivel, Tilt or Pivot feature support on this TV.
The vertical and horizontal measurements of this TV are 48.35 inches and 29.29 inches respectively. Coming to thickness, it is 1.85 inches thick.
In total it weighs around 19.9 Kgs (including stand). Without stand, it weighs 18.9 KGs.
Hardware and Audio
The TV comes with a 4-Core CPU. However, LG didn't provide any information on the total RAM on this TV.
Speaking of OS, the LG OLED55B26LA runs webOS 22 Operating System.
For display connectivity, LG has provided two HDMI 2.0 ports, two HDMI 2.1 ports and one S/PDIF port on this TV.
To connect USB devices, you will have two USB 2.0 ports. Other connectivity ports include — 1x Satellite In (Sub — F-type female), 1x Antenna (RF) (female), 1x Satellite In (Main — F-type female), 1x CI+ 2.0 and 1x Ethernet RJ45.
For wireless connectivity on this TV, the manufacturer has provided a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct, Bluetooth 5.0 and DLNA.
The Audio unit of this TV is powered by 2 x 10W speakers.
In terms of power consumption, it consumes 84W on average and 0.5W on standby.
Both 110V and 220V outlets are supported on this unit.
