ABOUT THIS TV

LG OLED77ZZPUA 400x400 Image LG OLED77ZZPUA

The OLED77ZZPUA is a 77 inch 8K TV from LG. It was launched in 2022. It features a True 10-bit OLED panel.

The maximum resolution it can achieve is 7680 x 4320 @ 120 Hz with a pixel density of 115 ppi.

Picture Quality

After screen size and resolution, the next important specification to look for in a display is its Color Reproduction Accuracy, which is defined by its color gamut specification.

LG has not provided a color gamut rating for this TV. So we have to take a guess.

Now, since the TV comes with an OLED panel, so we can conclude that the equivalent sRGB coverage of this TV would be far above 100%.

What Color Gamut means ?

Color gamut spec of a TV is a measure of the range of colors that the TV can produce.

A TV with poor color reproduction will produce undersaturated/washed out colors that will spoil your immersive experience.

It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 Adobe RGB, rec.2020.

But don't worry, below is a chart that will help you choosing a TV with good color accuracy.

Color Gamut Chart

Now, after color gamut, the static contrast specification of a TV holds almost equal role in picture quality.

The importance of static contrast ratio

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 tells the intensity of black levels. That is, a TV with SC ratio < 1000:1 will produce black images something like this:

Example of a disply with low contrast ratio

Apart from that, such TVs may suffer from backlight bleeds that will rob your experience — as shown below.

Note that, 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.

For a display with OLED panel, its static constrast would be Infinity : 1. So no need to worry about this at all.

HDR is also supported on this TV in form of Dolby Vision, HLG (Hybrid Log Gamma), Dolby Vision IQ and HDR10 Pro.

Coming to brightness, it is capable of producing a peak brightness of 250 nits.

Gaming Performance

If you are planning to use the TV other than watching videos — say as a PC monitor or Gaming, you should get a TV with lowest input lag. For gaming however, both the input lag and response time impacts the performance.

The input lag on the LG OLED77ZZPUA is 5 ms and its minimum response time is 1 ms. So its a go-to TV if you are interested in gaming.

What is Input lag ?

This lag is the amount of time at which key-presses or mouse movements changes the content of the TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.

But ideally, get a TV that has an input lag and response time of less than 20ms.

Dimensions and Ergonomics

The TV measures 77 inches vertically and 67.6 inches horizontally. It is just 1.27 inches thick.

In total it weighs 43.4 KGs (including stand). Without stand, it weighs 42.6 Kgs.

Speaking of ergonomics — If you plan to wall mount the TV, you can make use of the VESA mount provided with this TV, which by the way has an interface size of 400 x 400 mm. Swivel, Tilt or Pivot features are not supported on this unit.

Hardware and Audio

The TV comes with a Quad Core CPU and a 2-Core GPU.. There is no mention about the RAM on the TV's specsheet.

The UI on this TV is powered by 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, you will have three USB 2.0 ports. Other connectivity ports include — 1x Cable/Antenna In (F-type female), 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.

Now, for audio, LG has provided 4 x 10W speakers on the OLED77ZZPUA. It also comes with a built-in sub-woofer. So you may not have to invest on any external sound system.

In terms of power usage, on average, it uses 248 watts and on standby, it uses 0.5 watts.

For powering this unit, you'll need an 100 V - 120 V/50 Hz - 60 Hz outlet.
