Launched in the year 2022, the 70UQ90009LA is a 70" 4K TV from LG. It comes with a True 8-bit VA panel.
It can display a maximum resolution of 3840 x 2160 @ 60 Hz with a pixel density of 63 ppi.
After screen size and resolution, the very next spec of a display that will impact your viewing experience is Color Gamut.
This TV doesn't provide a color gamut specification, but don't worry, we have other means to guess that. Now, since the TV features a big 70 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 accuracy on this TV will be Lifelike! It will produce accurate colors.
What Color Gamut means ?
Color gamut spec of a display is the measurement of the range of colors that the display can display.
A panel with poor color accuracy will produce undersaturated colors that will not be pretty to look at.
It is specified in different units - sRGB(most popular), NTSC, DCI P3 etc. It is upto the manufacturer which one they choose.
But don't worry, below is a chart that you can use to choose a TV with good color accuracy.
Other than color accuracy, the static contrast ratio of a TV holds almost equal role in picture quality.
What is Static Contrast ratio ?
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.
This defines the intensity of black levels. That is, a TV with static contrast ratio less than 1000:1 may produce black images something like this:
Apart from this, such TVs are also prone backlight bleeds that will impact your experience — as shown below.The image is an example of another display, it is not this one
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, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
However, we couldn't find a static contrast ratio specification for this TV. So we have to make an assumptionagain based on the TV's other specifications. If you are reading our blogs, you may already know that Most always come with high contrast ratios. This TV comes with the same, so you can expect the static contrast ratio to be atleast 3000:1 or above.
HDR10 Pro and HLG (Hybrid Log Gamma) are also supported on this TV.
As for brightness, the peak luminance the TV can produce is 250 nits, powered by Direct LED backlight technology.
Now if you are going to use your TV other than using it as a TV — like as a PC monitor or Gaming, you would want to get a TV with lowest input lag. For gaming, both the input lag and response time impacts the performance.
Sadly, there is no specification for input lag on this TV. But as this is not a cheap TV, input lag on this TV could be 20ms or below.
What is Input lag ?
This lag is the amount of time at which device inputs 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 has an input lag and response time of less than 20ms.
Dimensions and Ergonomics
Vertically, the TV measures 70 inches and horizontally 62.11 inches. It weighs approximately 22.5 Kgs. So plan your space accordingly.
Now, speaking of ergonomics — VESA mount is supported on this TV with an interface size of 400 x 400 mm. Swivel, Tilt or Pivot features are not supported on this unit.
Hardware and Audio

For connecting USB devices, you will have 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 connectivity on this TV, the manufacturer has provided Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth 5.0 and DLNA.
Speaking of speakers, LG has provided 2 x 10W built-in speakers on the TV.
In terms of power consumption, the TV consumes 135 watts on average and 0.5 watts on standby.
For powering this unit, you'll need an 220 V - 240 V/50 Hz - 60 Hz outlet.
