Launched in the year 2022, the OLED77C29LD is a 77" 4K TV from LG. It comes with 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.
After screen size and resolution, the next important specification to look for in a display is its Color Reproduction Accuracy (defined by its color gamut specification).
This TV doesn't provide a color gamut specification, but don't worry, we have other means to guess that.
As the TV 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 specification of a display is the measurement of the range of colors that the display can show.
Meaning, this specification tells the ability of a TV to produce accurate colors. A TV 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 define color gamut. Viz — sRGB (most popular), NTSC 1953, DCI P3 to name a few.
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.
After color gamut, you should look at the static contrast specification as it influences the picture quality the same way.
Understanding Static Contrast
There are two types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio. Dynamic doesn't matter much.
This defines the intensity of black levels. That is, a TV with static contrast ratio < 1000:1 will produce black images something like this:
Apart from 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 produce less shades of colors, 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.. 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.
As for brightness, it can go as bright as 250 nits.
Now if you are planning to use the TV other than watching videos — say as a PC monitor or for gaming purposes, you would want to get a TV that features the lowest input lag. For gaming however, both input lag and response time affects the performance.
The input lag on this TV is 5 ms and its minimum response time is 1 ms. For a TV, its the best you can get for gaming.
Understanding Input lag and response time
This lag is the amount of time at which key-presses or mouse movements changes the content of your TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
Although for better experience, get a TV that has an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Now, coming to ergonomics — a VESA mount with interface size of 300 x 200 mm is provided for wall-mounting. However, there is no Swivel, Tilt or Pivot feature support in this TV.
The width of this TV is 67.36 inches while its height is 40.75 inches.
It is 1.85 inches thick. In total this TV weighs around 24.1 Kgs including stand. Without stand, it weighs 20.8 Kgs. So plan your space accordingly.
Hardware and Audio
The TV is powered by 4-Core CPU. There is no information on the available RAM on this TV.
Speaking of OS, the LG OLED77C29LD runs webOS 22 Operating System.
For display connectivity, LG has provided 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 Satellite In (Main — F-type female), 1x Antenna (RF) (female), 1x IR Out, 1x CI+ 2.0 and 1x Ethernet RJ45.
For connecting to this TV wirelessly, the manufacturer has provided a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct, Bluetooth 5.0 and DLNA.
Speaking of speakers, it is packaged with 2 x 10W speakers. It also comes with a built-in sub-woofer. So you may not have to invest on any external sound system.
As for power consumption, it consumes 119W on average and 0.5W on standby.
For powering this unit, you will need either a 110V or 220V outlet @ 50Hz-60Hz.
