Launched in the year 2022, the 75UQ91006LA is a 75" 4K TV from LG. It features a 10-bit IPS panel.
It can display a max resolution of 3840 x 2160 @ 60 Hz with a pixel density of 59 ppi.
Now, the next important specification of a display that impacts picture quality is Color Gamut.
LG did not provide a color gamut specification for this TV. So we have to take a guess. 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. Undoubtedly The color quality on this TV will be Lifelike! Meaning it is capable of producing accurate colors.
Understanding the Color Gamut Specification
Color gamut specification of a display is the measurement of the range of colors that the TV can produce.
Put Simply, it indicates the ability of a display to produce accurate colors. A TV with low color gamut coverage will miss out on some colors (such as deep red), so the image produced will look "washed out" in colors.
Different manufacturers use different measurement standards to specify color gamut. Viz — sRGB, NTSC 1953, DCI P3 to name a few.
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 impacts the picture quality the same way.
What is 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 look muddy as shown in below image.
As you can see, this will rob your experience considerably.
Think of static contrast as another dimension to details — just like resolution. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, so 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. Most IPS panels come with a static contrast ratio between 700:1 - 1500:1. Considering its a 4K TV, we can assume the ratio of LG 75UQ91006LA would be 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, it is capable of producing a maximum brightness of 250 nits. The backlight used on the panel is Direct LED.
If you are planning to use your TV solely for content consumption, you can safely ignore these specs. But if you are also going to use the TV for gaming or use it as a PC monitor, make sure to get a TV with the lowest input lag and response time.
Sadly, there is no specification for input lag on this TV. Now, since this is not a cheap TV from LG, we can expect an input lag of less than 20ms.
What is Input Lag and Why it matters ?
This lag is the amount of time at which your key-presses/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.
Although for better experience, look for a TV that features an input lag and response time of < 20ms.
Dimensions and Ergonomics
The width of this TV is 66 inches while its height is 41.14 inches.
It is just 2.36 inches thick. It weighs approximately 31.4 kilograms, another 3.2 kgs if you include stand.
Now, 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 in this TV.
Hardware and Audio
The TV is powered by 4-Core CPU. However, LG didn't provide any info about the total available RAM on the TV's official specsheet.
To power its UI, the TV runs webOS 22 Operating System.
For display connectivity, LG has provided two HDMI 2.0 ports and two HDMI 2.1 ports on this TV.
To connect USB devices, you will have two USB 2.0 ports. Other connectivity ports include — 1x CI+ 2.0, 1x Antenna (RF) (female), 1x Satellite In (F-type female) and 1x Ethernet RJ45.
For connecting to this TV wirelessly, 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 75UQ91006LA.
In terms of power consumption, it consumes 135 Watts on average and 0.5 Watts on standby.
It supports a power outlet of 220 V - 240 V/50 Hz - 60 Hz.
