The OLED77G2PUA is a 77 inch 4K TV from LG. It was launched in 2022. It comes with a True 10-bit OLED evo panel. The maximum resolution it can display is 3840 x 2160 @ 120 Hz with a pixel density of 57 ppi.
Picture Quality
After screen size and resolution, the next most important specification to look for in a display is its Color Reproduction Accuracy (defined by its color gamut specification).
This TV doesn't come with a color gamut specification, but don't worry, we have other means to guess that. Since it features an OLED panel, so we can conclude that the equivalent sRGB coverage of this TV would be far above 100%.
Understanding Color Gamut
Color gamut spec of a TV is the measurement of the range of colors that it can display.
Meaning, this specification determines the ability of a TV to produce accurate colors. A panel with low gamut coverage will miss out on some colors (such as deep red), the result would be a "washed out" picture quality.
Different manufacturers use different measurement standards to specify color gamut. Such as — sRGB (most popular), NTSC 1953, DCI P3 Adobe RGB and rec.2020.
But you don't need to worry about that, below is a chart that you can use to choose a TV with good color accuracy.
Now, after color gamut, you should look at the static contrast specification as it impacts the picture quality substantially.
Understanding the static contrast ratio of a TV
Static contrast ratio of a TV corresponds to its Black levels. A TV with low static contrast ratio (<1000:1) will not produce deep blacks. Apart from this, such TVs may suffer from backlight bleeds such as this:
The image is an example of another display, it is not this oneNeedless to say, this will impact your viewing experience, especially in a dark room.
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.
Given this TV comes with an OLED panel, its static constrast would be Infinity : 1. 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, so that's a plus.
Coming to brightness, the peak luminance the LG OLED77G2PUA can produce is 250 nits.
Gaming Performance
If you aren't planning to game on this TV, 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, make sure to get a TV that features the lowest input lag and response time.
The input lag on the LG OLED77G2PUA is 5 ms and its minimum response time is 1 ms. Gamers gonna love this TV.
Understanding Input lag and response time
This lag is the latency at which your key-presses/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.
Although for better experience, look for 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 67.4 inches and 40.9 inches respectively.
Coming to thickness, it is 1 inches thick. In total the TV weighs 41.1 kilograms (including stand). Without stand, it weighs 35.11 KGs. So plan your space accordingly.
Coming to ergonomics — VESA mount is supported on this TV with an interface size of 300 x 300 mm. There is no Swivel, Tilt or Pivot feature support in this TV.
Hardware and Audio
The TV comes with a Quad Core CPU. However, LG didn't provide any info on the total RAM on this TV.
The Operating System on this TV is webOS 22.
For display connectivity, there are four HDMI 2.1 ports and one S/PDIF port on this TV.
To connect USB devices, you will have three USB 2.0 ports. Other connectivity ports include — 1x Cable/Antenna In (F-type female), 1x RS232 (C), 1x IR Out and 1x Ethernet RJ45.
For connecting to this TV wirelessly, you will have — a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct, Bluetooth 5.0 and DLNA.
For audio, LG has provided 4 x 10W built-in speakers on the TV. It also comes with a built-in sub-woofer. So you may not have to invest on any external sound system.
