ABOUT THIS TV

LG OLED77ZZ9LA 400x400 Image LG OLED77ZZ9LA

Launched in the year 2022, the OLED77ZZ9LA is a 77" 8K TV from LG. It features a True 10-bit OLED panel.

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

Picture Quality

After screen size and resolution, the next important feature of a display is its Color Reproduction, which is defined by its color gamut specification.

This TV doesn't provide a color gamut specification, so we have to take a guess.

As it comes with an OLED panel, there is no need to worry about color accuracy. Because OLED panels ALWAYS come with over 100% sRGB coverage.

Understanding the Color Gamut Specification

Color gamut specification of a display 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 spoil your immersive experience.

It is specified in different units - sRGB,sRGB (standard RGB), NTSC 1953, DCI P3 to name a few. It is upto the manufacturer which one they choose.

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, you should look at the static contrast specification as it impacts the picture quality substantially.

Understanding the static contrast specification

A TV with high enough static contrast ratio will produce natural deep blacks while a TV with low contrast ratio (<1000:1) will produce images that might look dusty as shown below.

Example of a display with low contrast ratio

As you imagine, this will affect your experience considerably.

Also note, 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, always 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.

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 can go as bright as 250 nits.

Gaming Performance

If you are going to use your TV other than using it as a TV — like as a PC monitor or Gaming, you should take a TV with 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. Pick this one if you are a gamer.

Understanding Input lag and response time

This lag is the latency at which your key-presses or mouse movements changes the content of the screen. For casual Non-FPS games, input lag doesn't matter much.

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

Dimensions and Ergonomics

The vertical and horizontal measurements of this TV are 67.6 inches and 41.1 inches respectively. It is just 1.27 inches thick.

It weighs around 42.6 kgs, another 0.8 kgs if you include stand.

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. There is no Swivel, Tilt or Pivot feature support on this TV.
