The 43UQ91006LA is a 43 inch 4K TV from LG. 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 103 ppi.
Now, the next important spec of a display that will impact your viewing experience is its Color Gamut.
LG did not provide a color gamut rating for this TV. So we have to take a guess.
Now, since the TV comes with a 10bit IPS panel, we can safely assume its equivalent sRGB coverage to be 100% or above. The color quality on this TV will be Lifelike!
What Color Gamut means ?
Color gamut spec of a display is the measurement of the range of colors that the display can produce.
Put Simply, it determines the ability of a display to produce accurate colors. A TV with low color gamut coverage will miss out on some colors (such as deep red), the result would be a "washed out" picture quality.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC 1953, DCI P3 etc.
But you don't need to worry about that, here is a chart that will help you choosing a TV with good color accuracy.
Now, after color gamut, the static contrast specification of a TV has equally important role in picture quality.
Understanding the static contrast ratio of a TV
A TV with low static contrast ratio will not produce deep enough blacks and possibly can bleed backlight as shown below:The image is an example of another display, it is not this one
The static contrast ratio of above TV is rated 800:1. So make sure you get a TV with a static contrast of >= 1000:1. Ofcourse, More the better.
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, 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.
LG did not list a static contrast specification for this TV. So we have to make an assumption again based on the TV's other specifications. FYI — IPS panels come with a static contrast ratio between 700:1 - 1500:1. Now, for a 4K TV, we can imagine the ratio to be 1200:1 or above.
HDR10 Pro and HLG (Hybrid Log Gamma) are also supported on this TV.
As for brightness, it is can achieve a maximum brightness of 250 nits with the help of Direct LED backlight.
If you are not planning to game on this TV, you can safely ignore these specs. But if you are also planning to use the TV for gaming or use it as a PC monitor, you would want to 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.
Understanding Input lag and response time
This lag is the latency at which key-presses or mouse movements changes the content of the screen. 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 comes with an input lag and response time of < 20ms.
Dimensions and Ergonomics
Vertically, the TV measures 43 inches and horizontally 38 inches. It is just 2.25 inches thick. In total this TV weighs 10.0 kilograms including stand. Without stand, it weighs 8.9 KGs. So plan your space accordingly.
Speaking of ergonomics — a VESA mount with interface size of 200 x 200 mm is provided for wall-mounting. There is no Swivel, Tilt or Pivot feature support on this TV.
Hardware and Audio
The core of LG 43UQ91006LA is powered by a 4-Core CPU. However, we could'nt find any info on the available RAM on the TV's specsheet.
