Launched in the year 2022, the 43UQ7590PUB 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 most important specification of a display is its Color Reproduction (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 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. It may not produce super accurate colors, but for content consumption or gaming, it is more than enough.
What is Color gamut ?
Color gamut specification of a TV indicates the range of colors that the TV can show.
A panel with poor color reproduction will produce undersaturated colors that will spoil your immersive experience.
Different manufacturers use different units to define color gamut. Viz — sRGB, NTSC 1953, 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, next in the list is Static Contrast.
Understanding Static Contrast
A TV with high enough static contrast ratio will produce natural deep blacks while a TV with low contrast ratio (<1000:1) will produce images that will look dusty as shown in the below image.
As you imagine, this will affect your experience considerably.
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 produce less shades of colors, 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.
There's no mention of this spec in the TV's official specsheet. Again we have to make an assumption based on the TV's other specs. FYI — IPS panels come with a static contrast ratio between 700:1 - 1500:1. For a 4K TV, we can guess the ratio would be no less than 1200:1.
HDR is also supported on this TV in form of HDR10 Pro and HLG (Hybrid Log Gamma).
Coming to brightness, it is can achieve a peak brightness of 250 nits. The backlight of this TV is powered by Direct LED technology.
Now if you are going to use a TV other than using it as a TV — say as a PC monitor or Gaming, you would want to get a TV that features the lowest input lag. For gaming, both input lag and response time affects the performance.
Unfortunately, LG did not specify the input lag on this unit. But since this is not a cheap TV from LG, we can expect an input lag of less than 20ms.
What is Input lag ?
This lag is the latency at which key-presses/mouse movements changes the content of your TV. For casual Non-FPS games, input lag doesn't matter much.
For best of both worlds, get a TV that comes with an input lag and response time of < 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. There is no Swivel, Tilt or Pivot feature support in this TV.
Vertically, the TV measures 43 inches and horizontally 38.11 inches. Speaking of thickness, it is 2.2 inches thick. Overall the TV weighs approximately 8.9 KGs including its stand. Without stand, it weighs 8.8 KGs.
Hardware and Audio
The chipset of LG 43UQ7590PUB is powered by a Quad Core CPU. However, we could'nt find any info on the total RAM on the TV's specsheet.
The Operating System on this TV is webOS 22.
For display connectivity, there are two HDMI 2.0 ports on this TV.
To connect USB devices, you will have one USB 2.0 port. Other connectivity ports include — 1x Cable/Antenna In (F-type female), 1x RS232 (C) 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.
Coming to audio, it is packaged with 2 x 10W built-in speakers.
In terms of power usage, the TV consumes 87.68 Watts on average and 0.5 Watts on standby.
Both 110V and 220V outlets are supported on this unit.
