Launched in the year 2022, the 50UQ75006LF is a 50" 4K TV from LG. It features a True 8-bit VA panel. It can display a max resolution of 3840 x 2160 @ 60 Hz with a pixel density of 89 ppi.
Now, the very next spec of a display that defines picture quality is Color Gamut.
This TV doesn't come with a color gamut specification, so we have to take a guess. Now, since the TV features a big 50 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 accuracy on this TV should be Lifelike! It is capable of producing color accurate images.
Understanding Color Gamut
Color gamut specification of a display is the measurement of the range of colors that it can produce.
Put Simply, this specification tells the ability of a TV to produce accurate colors. A panel with low color gamut coverage will miss out on some colors (such as deep red), the result would be a "washed out" picture quality.
It is specified in different units - sRGB(most popular), NTSC 1953, DCI P3 etc. It is upto the manufacturer which one they choose.
But you don't need to worry about that, below is a chart that you can use to choose a TV with good color accuracy.
After color gamut, the static contrast specification of a TV holds almost equal role in picture quality.
Why its important?
There are two types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio. Dynamic doesn't matter much.
Static contrast specification defines the intensity of black levels. That is, a TV with SC ratio < 1000:1 may produce black images something like this:
Note that, such TVs are likely be prone to backlight bleeds that will impact your experience — as shown below.The image is an example of another display, it is not this one
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.
If given a choice, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
However, we were not able to find a static contrast ratio specification for this TV. So once again we have to take a guess based on the TV's other specifications. The static contrast ratio of this TV would be surely atleast 3000:1. As you know, this TV comes with a VA panel, these panels by nature have high contrast ratios.
HDR10 Pro and HLG (Hybrid Log Gamma) are also supported on this TV, so that's a plus.
As for brightness, it is capable of producing a peak brightness of 250 nits. The backlight used on the panel is Direct LED.
If you are planning to use your TV only for content consumption, you can ignore these specs. But if you are also planning to use the TV for gaming or use it as a PC monitor, you would want to take a TV that features the lowest input lag and response time.
Unfortunately, we cannot find the input lag specification for this unit. Now, as 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 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 less than 20ms.
Ergonomics and Dimensions
Coming to 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 on this TV.
Vertically, the TV measures 50 inches and horizontally 44.49 inches. In terms of thickness, it is 3.4 inches thick. Overall it weighs 11.4 Kgs including stand. Without stand, it weighs 11.3 Kgs. So plan your space accordingly.
Hardware and Audio
The TV comes with a 4-Core CPU. There is no data on the 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 on this TV.
To connect 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.
Wireless connectivity options on the LG 50UQ75006LF include 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.
As for power usage, on average, it uses about 70W. On standby, it takes 0.5 W.
It supports a power outlet of 220 V - 240 V/50 Hz - 60 Hz.
