Launched in the year 2022, the OLED77B26LA is a 77" 4K TV from LG. It features a True 10-bit OLED panel.
It can achieve a maximum resolution of 3840 x 2160 with a refresh rate of 120 Hz and pixel density of 57 ppi.
Picture Quality
After screen size and resolution, the very next feature of a display that impacts picture quality is Color Gamut.
LG did not provide a color gamut rating for this TV. So we have to take a guess.Since it comes with an OLED panel, there is no need to worry about color accuracy. Rest assured, Any OLED panel will always come with over 100% sRGB coverage.
Understanding the Color Gamut Specification
Color gamut spec of a TV is a measure of the range of colors that the display can show.
A display with poor color reproduction will produce undersaturated colors that will not be pretty to look at.
Different manufacturers use different units to define color gamut. Viz — 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 ratio of a TV holds almost equal role in picture quality.
Understanding Static Contrast
There are 2 types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio as dynamic doesn't matter much.
This specification tells the intensity of black levels. That is, a TV with static contrast ratio less than 1000:1 will produce black images something like this:
Moreover, such TVs are also prone backlight bleeds that will rob your experience — as shown below.
The image is an example of another display, it is not this oneOther than black levels, a TV with high constrast ratio allows you to see more details. So, resolution and static contrast ratio go hand in hand in a sense.
If given a choice, I will 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 Infinity:1. That's a plus point of owning an OLED TV. So no need to worry about this at all.
HLG (Hybrid Log Gamma), Dolby Vision, Dolby Vision IQ and HDR10 Pro are also supported on this TV.
Coming to brightness, it can go as bright as 250 nits.
Gaming Performance
If you are planning to use your TV only for content consumption, you can ignore these specifications. But if you are also going to use the TV for playing games or use it as a PC monitor, you would want to take a TV with the lowest input lag and response time.
The input lag on this TV is 5 ms and its minimum response time is 1 ms. You will love this TV if you are a gamer.
Understanding Input lag and response time
This lag is the latency at which inputs changes the content of the TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
Although for better experience, look for a TV that has an input lag and response time of less than 20ms.
Dimensions and Ergonomics
The TV measures 77 inches vertically and 67.83 inches horizontally. It is 2.18 inches thick. In total it weighs approximately 30.0 kgs including its stand. Without stand, it weighs 26.7 Kgs.
Speaking of ergonomics — VESA mount is supported on this TV with an interface size of 400 x 200 mm. Swivel, Tilt or Pivot features are not supported on this unit.
Hardware and Audio
The TV is powered by 4-Core CPU. However, LG didn't provide any specification about the RAM on the TV's official specsheet.
Speaking of OS, the LG OLED77B26LA 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.

For connecting to this TV wirelessly, the manufacturer has provided Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth 5.0 and DLNA.
For audio, it is packaged with 2 x 10W built-in speakers.
Now, coming to power consumption, the TV consumes 131 watts on average and 0.5 watts on standby.
