Launched in the year 2022, the TX-55LZ1500 is a 55" 4K TV from Panasonic. It features a True 10-bit OLED panel.
The maximum resolution it can achieve is 3840 x 2160 with a refresh rate of 120 Hz and a pixel density of 80 ppi.
After screen size and resolution, the next important feature of a display is its Color Reproduction Accuracy, which is defined by its color gamut specification.
Panasonic did not provide a color gamut rating for this TV. But don't worry, we have other means to guess that. considering the TV comes with an OLED panel, so we can conclude that the equivalent sRGB coverage of this panel would be far above 100%.
What Color Gamut means ?
Color gamut specification of a TV is the measurement of the range of colors that the display can produce.
What this means is, it indicates the ability of a TV to produce accurate colors. A display with low color gamut coverage will miss out on some colors (such as deep red), thus producing a "washed out" picture.
Different manufacturers use different units to define color gamut. Such as — sRGB, NTSC 1953, DCI P3 to name a few.
But don't worry, here is a chart that will help you choosing a TV with good color accuracy.
After color gamut, next in the list of important specifications that will impact your experience is Static Contrast.
What is Static Contrast ?
There are 2 types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio. Dynamic doesn't matter much.
This defines the intensity of black levels. That is, a TV with static contrast ratio < 1000:1 will produce black images something like this:
Moreover, such TVs are likely be prone to backlight bleeds that will rob your experience — as shown below.The image is an example of another display, it is not this one
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, 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 Infinity:1. That's a plus for OLED TVs. 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 brightness the Panasonic TX-55LZ1500 can produce is 250 nits.
Now if you are planning to use your TV other than using it as a TV — say as a PC monitor or for gaming purposes, you would want to take a TV with lowest input lag. For gaming, both input lag and response time affects the performance.
The input lag on the Panasonic TX-55LZ1500 is 5 ms and its minimum response time is 1 ms. You will love this TV if you are a gamer.
What is Input Lag and Why it matters ?
This lag is the latency at which your inputs changes the content of your TV. For casual Non-FPS games, input lag doesn't matter much.
But ideally, look for a TV that comes with an input lag and response time of < 20ms.
Ergonomics and Dimensions
Now, speaking of ergonomics — VESA mount is supported on this TV with an interface size of 300 x 300 mm. There is no Tilt or Pivot support in this unit except Swivel support.
Vertically, the TV measures 55 inches and horizontally 48.31 inches. It is just 2.72 inches thick. Overall this TV weighs approximately 20.5 Kgs including its stand. Without stand, it weighs 15.5 KGs. So plan your space accordingly.
