Launched in the year 2022, the 43UQ90009LA is a 43" 4K TV from LG. It features a True 8-bit IPS panel. The max. resolution it can display is 3840 x 2160 @ 60 Hz with a pixel density of 103 ppi.
After screen size and resolution, the next important feature to look for in a display is its Color Reproduction Accuracy, which is defined by its color gamut specification.
LG did not provide a color gamut specification for this TV. But don't worry, we have other means to guess that. This unit comes with an IPS panel and these panels are known to produce great colors. By this, we can assume that the sRGB coverage (equivalent) on this TV to be 70% or above. Although this TV may not produce super accurate colors, but for content consumption or gaming, it is good enough.
Understanding the Color Gamut Specification
Color gamut spec of a display indicates the range of colors that the TV can show.
Meaning, this specification indicates the ability of a TV to produce accurate colors. A panel with low gamut coverage will miss out on some colors (such as deep red), thus producing a "washed out" picture.
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 holds almost equal role in picture quality.
Why its important?
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. Moreover, such TVs may suffer from backlight bleeds such as this:The image is an example of another display, it is not this one
Obviously this will rob your experience, especially in a dark room.
Also, 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.
There is no mention of this specification in the TV's official datasheet. So we have to make an assumption again based on the TV's other specs. In general, IPS panels come with a static contrast ratio between 700:1 - 1500:1. As for a 4K TV, we can guess the ratio to be >= 1200:1.
HDR10 Pro and HLG (Hybrid Log Gamma) are also supported on this TV, so that's a plus.
Coming to brightness, it is capable of producing a maximum luminance of 250 nits with the help of Direct LED backlight.
If you are planning to use your TV solely for content consumption, you can ignore these specs. But if you are also planning 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.
Unfortunately, there is no specification for input lag on this TV. But since this is not a cheap TV, 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 device inputs changes the content of your TV. 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 has an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Speaking of 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 200 x 200 mm. However, there is no Swivel, Tilt or Pivot feature support in this TV.
The vertical and horizontal measurements of this TV are 38 inches and 24.49 inches respectively. It is 2.25 inches thick.
In total the TV weighs around 8.9 kgs including stand. Without stand, it weighs 8.8 kgs.
Hardware and Audio
The TV comes with a 4-Core CPU. However, LG didn't provide any specification about the total RAM on the TV's specsheet.
Speaking of OS, the LG 43UQ90009LA runs webOS 22 Operating System.
For display connectivity, LG has provided three HDMI 2.0 ports on this TV.
For connecting USB devices, it includes two USB 2.0 ports. Other connectivity ports include — 1x Satellite In (F-type female), 1x Antenna (RF) (female), 1x CI+ 2.0 and 1x Ethernet RJ45.
For connecting to this TV wirelessly, the manufacturer has provided Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth 5.0 and DLNA.
Speaking of speakers, it is packaged with 2 x 10W speakers.
Now, coming to power usage, the TV uses 53 Watts on average and 0.5 Watts on standby.
It supports a power outlet of 220 V - 240 V/50 Hz - 60 Hz.
