The 43UQ76909LE is a 43 inch 4K TV from LG. It was launched in 2022. It comes with a True 8-bit IPS panel.
The maximum resolution it can display is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 103 ppi.
After screen size and resolution, the next important spec of a display is its Color Reproduction, which is defined by its color gamut specification.
This TV doesn't provide a color gamut specification, but don't worry, we have other means to guess that. This unit comes with an IPS panel. Now, IPS panels are known to produce great colors out of the box. By this, we can assume that the sRGB coverage (equivalent) on this TV to be 70% or above. For content consumption and gaming, you may not need any better color accuracy than this anyway. So its good enough.
What is Color gamut ?
Color gamut spec of a TV is a measure of the range of colors that the display can produce.
A display with poor color reproduction will produce washed out colors that will spoil the immersion.
Different manufacturers use different measurement standards to define color gamut. Viz — sRGB (most popular), NTSC, DCI P3 Adobe RGB and rec.2020.
But you don't need to worry about that, here is a chart that you can use to choose a TV with good color accuracy.
After color gamut, you should look at the static contrast specification as it influences the picture quality substantially.
Understanding Static Contrast
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 might look dusty as shown below.
As you can see, this will affect your experience considerably.
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.
We couldn't find a static contrast ratio specification for this TV. So once again we have to make an assumption 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 guess the ratio would be atleast 1200:1 or above.
HDR10 Pro and HLG (Hybrid Log Gamma) are also supported on this TV, so that's a plus.
Coming to brightness, the peak luminance it can achieve is 250 nits, powered by Direct LED backlight.
If you aren't planning to game on this TV, you can ignore these specs. But if you are also going to use the TV for gaming or use it as a PC monitor, you would want to get a TV with the lowest input lag and response time.
Unfortunately, LG did not specify the input lag on this unit. But as this is not a cheap TV, input lag on this TV could be 20ms or below.
Understanding Input lag and response time
This lag is the latency at which your inputs changes the content of the screen. For casual Non-FPS games, input lag doesn't matter much.
Although for better experience, look for a TV that has an input lag and response time of < 20ms.
Ergonomics and Dimensions
Now, coming to ergonomics — a VESA mount with interface size of 200 x 200 mm is provided for wall-mounting. Swivel, Tilt or Pivot features are not supported on this unit.
The TV measures 43 inches vertically and 38.31 inches horizontally. Coming to thickness, it is just 3.35 inches thick.
It weighs around 8.0 Kgs and an additional 0.1 kgs including stand.
Hardware and Audio
The TV comes with a 4-Core CPU. However, we could'nt find any specification on the total RAM on the TV's official specsheet.
The UI on this TV is powered by webOS 22 Operating System.
For display connectivity, there are two HDMI 2.0 ports on this TV.
For connecting USB devices, you will have one USB 2.0 port. Other connectivity ports include — 1x Satellite In (Main — F-type female), 1x Antenna (RF) (female), 1x CI+ 2.0 and 1x Ethernet RJ45.
Regarding wireless connections, you will have — Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth 5.0 and DLNA.
The Audio unit of this TV is powered by 2 x 10W built-in speakers.
Speaking of power consumption, on average, this TV uses 54 Watts and on standby, it uses 0.5 Watts.
It supports a power outlet of 220 V - 240 V/50 Hz - 60 Hz.
