Launched in the year 2022, the OLED77C2PUA is a 77" 4K TV from LG. It features a True 10-bit OLED evo panel. The maximum resolution it can achieve is 3840 x 2160 @ 120 Hz with a pixel density of 57 ppi.
Now, the next important feature of a display that defines picture quality is its Color Gamut.
This TV doesn't come with a color gamut specification, so we have to take a guess. Now, since the TV features an OLED panel, so we can conclude that the equivalent sRGB coverage of this panel would be far above 100%.
Understanding Color Gamut
Color gamut specification of a TV indicates the range of colors that it can show.
In layman terms, it indicates 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), so the image produced will look "washed out" in colors.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC 1953, DCI P3 Adobe RGB, rec.2020. It is upto the manufacturer which one they choose.
But you don't need to worry about that, here is a chart that you can use to choose a TV with good color accuracy.
After color gamut, the static contrast ratio of a TV has equally important role in picture quality.
Understanding the static contrast specification
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 SC ratio < 1000:1 may produce black images something like this:
Note that, such TVs are likely be prone to backlight bleeds that will impact your experience — as shown below.The image is an example of another display, it is not this one
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, so lesser detail overall.
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 for OLED TVs. So no need to worry about this at all.
HDR is also supported on this TV in form of HLG (Hybrid Log Gamma), Dolby Vision, Dolby Vision IQ and HDR10 Pro.
As for brightness, it is can achieve a peak luminance of 250 nits.
If you are not interested in gaming, you can safely ignore these specs. But if you are also going to use the TV for gaming 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 LG OLED77C2PUA is 5 ms and its minimum response time is 1 ms. Pick this one if you are a gamer.
What is Input Lag and Why it matters ?
This lag is the latency at which your device inputs changes the content of the TV. For casual Non-FPS games, input lag doesn't matter much.
But ideally, get a TV that features an input lag and response time of < 20ms.
Dimensions and Ergonomics
Vertically, the TV measures 77 inches and horizontally 67.36 inches. Speaking of thickness, it is 1.85 inches thick. Overall the TV weighs 24.1 kilograms (including stand). Without stand, it weighs 20.8 KGs.
Coming to ergonomics — VESA mount is supported on this TV with an interface size of 300 x 200 mm. There is no Swivel, Tilt or Pivot feature support on this TV.
Hardware and Audio
The chipset of this TV is powered by 4-Core CPU. However, we could'nt find any information about the total available RAM on the TV's specsheet.
Speaking of OS, the LG OLED77C2PUA runs webOS 22 Operating System.
For display connectivity, there are four HDMI 2.1 ports and one S/PDIF port on this TV.
To connect USB devices, it includes 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 — Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth 5.0 and DLNA.
The Audio unit of this TV is powered by 2 x 10W speakers. It also comes with a built-in sub-woofer. So you don't have to invest on an external sound system.
Now, coming to power usage, on average, this TV uses around 157.39 Watts. On standby, it takes 0.5 Watts.
For powering this unit, you'll require either a 110V or 220V outlet @ 50Hz-60Hz.
