ABOUT THIS TV

Panasonic TH-55LX900Z 400x400 Image Panasonic TH-55LX900Z

The TH-55LX900Z is a 55 inch 4K TV from Panasonic. It was launched in 2022. It comes with a 10-bit IPS panel. It can achieve a maximum resolution of 3840 x 2160 with a refresh rate of 120 Hz and pixel density of 80 ppi.

Picture Quality

After screen size and resolution, the next important feature of a display that will impact your viewing experience is Color Gamut.

This TV doesn't come with a color gamut specification, so we have to make an assumption based on its panel type. As this TV features a 55 inch screen, it won't come with a cheap panel, so here we can assume its equivalent sRGB coverage to be 90-100% or above. The color quality on this TV should be Lifelike! Meaning it will produce accurate colors.

Understanding the Color Gamut Specification

Color gamut specification of a TV indicates the range of colors that the TV can show.

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

It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 Adobe RGB, rec.2020. It is upto the manufacturer which one they choose.

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

Color Gamut Chart

After color gamut, next in the list of important specifications that will impact your experience is Static Contrast.

Understanding the static contrast ratio

The static contrast ratio of a TV corresponds to its Black levels. A Display with low static contrast ratio (<1000:1) will not produce deep blacks. Apart from this, such displays are likely to suffer from backlight bleeds such as this:

Needless to say, this will rob your viewing experience, especially in a dark room.

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 produce less shades of colors, thus 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 8000:1., good enough to achieve deep blacks and eye-catching visuals. The panel comes with local dimming backlight which is a plus.

HDR10, HDR10+, HLG (Hybrid Log Gamma), Dolby Vision, Dolby Vision IQ and HDR10+ Adaptive are also supported on this TV, so that's a plus.

Coming to brightness, it is can produce a maximum brightness of 250 nits, which is powered by Edge LED backlight.

Gaming Performance

Now if you are going to use the TV other than using it as a TV — 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 affects the performance.

Sadly, Panasonic did not specify the input lag on this unit. But since this is not a cheap TV from Panasonic, input lag on this TV could be 20ms or below.

What is Input lag ?

This lag is the amount of time at which your inputs changes the content of your display. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.

But ideally, look for a TV that features an input lag and response time of < 20ms.

Dimensions and Ergonomics

The TV measures 55 inches vertically and 48.46 inches horizontally. Overall the TV weighs approximately 18.5 kgs (including stand). Without stand, it weighs 16.0 Kilograms.

Now, coming to ergonomics — VESA mount is supported on this TV with an interface size of 300 x 300 mm. Swivel, Tilt or Pivot features are not supported on this unit.

Hardware and Audio

The UI on this TV is powered by my Home Screen 7.0 Operating System.
