Launched in the year 2022, the 75UQ90009LA is a 75" 4K TV from LG. It features 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 59 ppi.
Picture Quality
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 come with a color gamut specification, but don't worry, we have other means to guess that.
As this TV features amassive 75 inch screen, it won't come with a cheap panel, so here we can assume its equivalent sRGB coverage to be 90-100% or above. The color quality on this TV should be Lifelike! Meaning it is capable of producing color accurate images out of the box.
What Color Gamut means ?
Color gamut spec of a TV is a measure of the range of colors that the TV can display.
A panel with poor color accuracy will produce undersaturated colors that will not be pretty to look at.
Different manufacturers use different units to specify color gamut. Viz — sRGB (standard RGB), NTSC, DCI P3 Adobe RGB and rec.2020.
But you don't need to worry about that, here is a chart that will help you choosing a TV with good color accuracy.
After color gamut, the static contrast of a TV also impacts its picture quality.
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 might look dusty as shown in below image.
As you can see, this will affect your experience considerably.
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, thus lesser detail overall.
There is no mention of this spec in the TV's official datasheet. 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 assume the ratio of LG 75UQ90009LA to be on the upper side, that is atleast 1200:1.
HDR is also supported on this TV in form of HDR10 Pro and HLG (Hybrid Log Gamma).
As for brightness, it is capable of producing a peak luminance of 250 nits. The panel of this TV is powered by Direct LED backlight technology.
Gaming Performance
If you are planning to use your TV only for content consumption, you can ignore these specifications. But if you are also planning to use the TV for gaming 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. 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 amount of time at which your key-presses or mouse movements changes the content of your display. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
For best of both worlds, look for a TV that has an input lag and response time of < 20ms.
Dimensions and Ergonomics
The width of this TV is 66 inches while its height is 40.43 inches. In terms of thickness, it is just 2.36 inches thick.
Overall the TV weighs around 31.8 Kgs (including stand). Without stand, it weighs 31.4 kgs.
Coming to ergonomics — VESA mount is supported on this TV with an interface size of 400 x 400 mm. However, there is no Swivel, Tilt or Pivot feature support on this TV.
Hardware and Audio
The chipset of this TV is powered by 4-Core CPU. However, we could'nt find any info on the RAM on the TV's specsheet.
To power its UI, the TV 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.
Regarding wireless connections, the manufacturer has provided a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct, Bluetooth 5.0 and DLNA.
Coming to audio, it is packaged with 2 x 10W speakers.
Now, coming to power usage, it uses 135 watts on average and 0.5 watts on standby.
It supports a power outlet of 220 V - 240 V/50 Hz - 60 Hz.
