The TX-55LZ1000 is a 55 inch 4K TV from Panasonic, launched in the year 2022. It features a True 10-bit OLED panel.
It can display a max resolution of 3840 x 2160 @ 120 Hz with a pixel density of 80 ppi.
After screen size and resolution, the very next feature of a display that defines picture quality is its Color Gamut.
Panasonic did not provide a color gamut specification for this TV. So we have to take a guess. considering it features an OLED panel, so we can conclude that the equivalent sRGB coverage of this panel would be far above 100%.
Understanding Color Gamut
Color gamut spec of a TV is the measurement of the range of colors that the display can display.
A display with poor color reproduction will produce undersaturated colors that will spoil your immersive experience.
It is specified in different units - sRGB(most popular), NTSC, DCI P3 to name a few. It is upto the manufacturer which one they choose.
But don't worry, here is a chart that you can use to choose a TV with good color accuracy.
Other than color accuracy, you should look at the static contrast specification as it influences the picture quality substantially.
The importance of static contrast ratio
A TV with low static contrast ratio will not produce deep enough blacks and may bleed backlight as in the images below:The image is an example of another display, it is not this one
The static contrast ratio of above TV is 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More is better.
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.
For a display with OLED panel, its static constrast will be Infinity : 1. So no need to worry about this at all.
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.
Coming to brightness, the peak luminance the Panasonic TX-55LZ1000 can produce is 250 nits.
Now if you are planning to use your TV other than watching videos — say as a PC monitor or Gaming, you would want 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 the Panasonic TX-55LZ1000 is 5 ms and its minimum response time is 1 ms. For a TV, its the best you can get for gaming.
What is Input Lag and Why it matters ?
This lag is the amount of time at which device inputs changes the content of your display. For casual Non-FPS games, input lag doesn't matter much.
For best of both worlds, look for a TV that features an input lag and response time of < 20ms.
Dimensions and Ergonomics
The width of this TV is 48.31 inches while its height is 30.35 inches. Speaking of thickness, it is 2.72 inches thick. It weighs 14.5 kgs, another 5.0 kgs if you include stand. So plan your space accordingly.
Now, speaking of ergonomics — a VESA mount with interface size of 300 x 300 mm is provided for wall-mounting. However, there is no Tilt or Pivot support on this unit except Swivel support.
Hardware and Audio
