The 43UQ75006LF is a 43 inch 4K TV from LG. It was launched in 2022. It features a True 8-bit IPS panel.
It can display a max resolution of 3840 x 2160 @ 60 Hz with a pixel density of 103 ppi.
After screen size and resolution, the next most important specification to look for in a display is its Color Reproduction Accuracy, which is defined by its color gamut specification.
This TV doesn't provide a color gamut specification, so we have to take a guess. This unit comes with an IPS panel and these panels are known to produce great colors out of the box. By this, we can assume the sRGB coverage (equivalent) on this TV to be 70% or above. For content viewing and gaming purposes, you may not need any better than this anyway. So its good enough.
Understanding the Color Gamut Specification
Color gamut spec of a display indicates the range of colors that it can show.
A panel with poor color reproduction will produce washed out colors that will spoil the immersion.
It is specified in different units - sRGB,sRGB (standard RGB), NTSC, DCI P3 to name a few. It is upto the manufacturer which one they choose.
But don't worry, here is a chart that will help you choosing a TV with good color accuracy.
Now, after color gamut, the static contrast of a TV also impacts its picture quality.
The importance of static contrast ratio
The static contrast ratio of a TV corresponds to its Black levels. A Display with low static contrast ratio (less than 1000:1) will not produce deep blacks. Moreover, such TVs are likely to 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 considerably, especially in a dark room.
Think of static contrast as another dimension to details — just like resolution. 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, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
We couldn't find a static contrast ratio specification for this TV. So once again we have to take a guess based on the TV's other specs. In general, IPS panels come with a static contrast ratio between 700:1 - 1500:1. Now, for a 4K TV, we can imagine the ratio of LG 43UQ75006LF would be >= 1200:1.
HDR10 Pro and HLG (Hybrid Log Gamma) are also supported on this TV.
As for brightness, it is can produce a maximum brightness of 250 nits. The panel of this TV is powered by Direct LED backlight.
Now if you are planning to use your TV other than watching videos — say as a PC monitor or Gaming, you would want to take a TV with lowest input lag. For gaming however, both the input lag and response time affects the performance.
Sadly, LG did not specify the input lag on this unit. But since this is not a cheap TV from LG, input lag on this TV could be 20ms or below.
Understanding Input lag and response time
This lag is the amount of time at which your device inputs changes the content of the TV. For casual Non-FPS games, input lag doesn't matter much.
For best of both worlds, look for a TV that comes with an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Speaking of ergonomics — VESA mount is supported on this TV with an interface size of 200 x 200 mm. Swivel, Tilt or Pivot features are not supported on this unit.
The width of this TV is 38.31 inches while its height is 24 inches. It is 3.35 inches thick.
Overall it weighs approximately 8.1 Kgs (including stand). Without stand, it weighs 8.0 Kgs. So plan your space accordingly.
Hardware and Audio
The core of this TV is powered by a Quad Core CPU. However, LG didn't provide any information on the total RAM on this TV.
To power its UI, the TV runs webOS 22 Operating System.
For display connectivity, LG has provided two HDMI 2.0 ports on this TV.
To connect USB devices, it includes 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.
For wireless connections, you will have — a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct, Bluetooth 5.0 and DLNA.
Now, for audio, LG has provided 2 x 10W built-in speakers on the 43UQ75006LF.
Speaking of power usage, on average, it uses around 54 Watts. On standby, it uses 0.5 Watts.
It supports a power outlet of 220 V - 240 V/50 Hz - 60 Hz.
