The 55NANO756QA is a 55 inch 4K TV from LG, launched in the year 2022. It comes with a 10-bit VA panel.
It can achieve a max resolution of 3840 x 2160 with a refresh rate of 60 Hz and pixel density of 80 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.
LG has not provided a color gamut rating for this TV. So we have to take a guess. As this TV features a big 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. Undoubtedly The color quality on this TV will be Lifelike! It will produce color accurate images AS IT IS intended.
What Color Gamut means ?
Color gamut specification of a TV is the measurement of the range of colors that it can show.
A display with poor color reproduction will produce undersaturated/washed out colors that will spoil the immersion.
Different manufacturers use different measurement standards to define color gamut. Viz — sRGB (standard RGB), NTSC, DCI P3 Adobe RGB and rec.2020.
But don't worry, below is a chart that will help you choosing a TV with good color accuracy.
Now, next in the list that will impact your experience is Static Contrast.
Understanding the static contrast ratio of a TV
A TV with high enough static contrast ratio will produce deep blacks while a TV with low contrast ratio (<1000:1) will produce images that will look dusty as shown in below image.
As you can imagine, this will rob your experience considerably.
Also, a TV with high constrast ratio enables you to see more details. So, resolution and static contrast ratio go hand in hand.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
There is no mention of this spec in the TV's official datasheet. So once again we have to make an assumption based on the TV's other specs. VA panels usually have superior contrast ratios. As you know, this TV features the same, so you can expect the static contrast ratio to be atleast 3000:1 or above.
HDR10 Pro and HLG (Hybrid Log Gamma) are also supported on this TV.
As for brightness, it can go as bright as 250 nits. The backlight used on the panel is Direct LED.
Gaming Performance
If you aren't into gaming, you can safely ignore these specifications. But if you are also going to use the TV for playing games or use it as a PC monitor, you should get a TV that features the lowest input lag and response time.
Sadly, there is no specification for input lag on this TV. Now, as this is not a cheap TV from LG, we can expect an input lag of less than 20ms.
What is Input Lag and Why it matters ?
This lag is the latency at which 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.
Although for better experience, get a TV that has an input lag and response time of less than 20ms.
Dimensions and Ergonomics
The vertical and horizontal measurements of this TV are 48.62 inches and 30.47 inches respectively.
Speaking of thickness, it is just 2.29 inches thick.
Overall this TV weighs 14.8 Kgs including stand. Without stand, it weighs 14.6 KGs.
Now, coming to 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 300 x 300 mm. The unit doesn't come with Swivel, Tilt or Pivot support.
