ABOUT THIS TV

Panasonic TX-77LZ2000 400x400 Image Panasonic TX-77LZ2000

The TX-77LZ2000 is a 77 inch 4K TV from Panasonic, launched in the year 2022. It comes with a True 10-bit OLED panel. It can achieve a max resolution of 3840 x 2160 with a refresh rate of 120 Hz and pixel density of 1461 ppi.

Picture Quality

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

This TV doesn't come with a color gamut specification, so we have to take a guess.Since the TV features an OLED panel, there is no need to worry about color accuracy. Any OLED panel will always come with over 100% sRGB coverage.

Understanding Color Gamut

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

A TV with poor color reproduction will produce undersaturated colors that will spoil the immersion.

Different manufacturers use different measurement standards to define color gamut. Viz — sRGB (most popular), NTSC, DCI P3 Adobe RGB and rec.2020.

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

Color Gamut Chart

After color gamut, you should look at the static contrast specification as it impacts the picture quality the same way.

What is Static Contrast ?

Static contrast ratio of a TV corresponds to its Black levels. A TV with low static contrast ratio (less than 1000:1) will not produce deep blacks. Also, such displays may suffer from backlight bleeds such as below:

Obviously this will affect your experience considerably, especially in a dark room.

Also, 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, thus 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.

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

As for brightness, it is can achieve a peak luminance of 250 nits.

Gaming Performance

If you are going to use a TV other than using it as a TV — say as a PC monitor or Gaming, make sure to get a TV that features the lowest input lag. For gaming, both the 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 amount of time at which your device inputs changes the content of the TV. For casual Non-FPS games, input lag doesn't matter much.

For best of both worlds, look for a TV that has an input lag and response time of less than 20ms.

Ergonomics and Dimensions

Now, 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. The unit doesn't come with Swivel, Tilt or Pivot support.

The TV measures 77 inches vertically and 68.21 inches horizontally. Overall, it weighs approximately 22.5 Kgs. So plan your space accordingly.
