The 70UQ81006LB is a 70 inch 4K TV from LG. It was launched in 2022. It features a True 8-bit VA panel.
It can achieve a maximum resolution of 3840 x 2160 @ 60 Hz with a pixel density of 63 ppi.
After screen size and resolution, the next most important spec to look for in a display is its Color Reproduction, which is defined by its color gamut specification.
LG has not provided a color gamut specification for this TV. But don't worry, we have other means to guess that.
As this TV features amassive 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. The color quality on this TV should be Lifelike! Meaning it will produce color accurate images.
What is Color gamut ?
Color gamut specification of a display indicates the range of colors that the TV can display.
What this means is, this specification determines the ability of a display to produce accurate colors. A panel with low color gamut coverage will miss out on some colors (such as deep red), thus producing a "washed out" picture.
Different manufacturers use different units to specify color gamut. Such as — sRGB (standard RGB), NTSC, DCI P3 to name a few.
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 specification of a TV has equally important role in picture quality.
Understanding the static contrast ratio of a TV
There are 2 types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio as dynamic doesn't matter much.
This specification defines the intensity of black levels. That is, a TV with SC ratio < 1000:1 will produce black images something like this:
Note that, such TVs are likely to suffer from 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, so lesser detail overall.
If given a choice, always prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
LG did not specify static contrast specification for this TV. Again we have to make an assumption based on the TV's other specifications. If you are reading our blogs, you may already know that Most usually have high contrast ratios. This TV comes with the same, so the static contrast ratio would be easily atleast 3000:1 or above.
HDR10 Pro and HLG (Hybrid Log Gamma) are also supported on this TV, so that's a plus.
As for brightness, it can go as bright as 250 nits with the help of Direct LED backlight.
Now if you are planning to use the TV other than using it as a TV — say as a PC monitor or for gaming purposes, make sure to get a TV that features the lowest input lag. For gaming however, both input lag and response time impacts the performance.
Sadly, LG did not specify the input lag on this unit. Now, since this is not a cheap TV from LG, input lag on this TV could be 20ms or below.
What is Input Lag and Why it matters ?
This lag is the latency at which inputs changes the content of your display. For casual Non-FPS games, input lag doesn't matter much.
Although for better experience, look for a TV that features an input lag and response time of less than 20ms.
Dimensions and Ergonomics
The vertical and horizontal measurements of this TV are 61.5 inches and 38.82 inches respectively.
In terms of thickness, it is 2.36 inches thick. Overall it weighs around 31.7 kilograms (including stand). Without stand, it weighs 28.5 Kilograms.
Speaking of ergonomics — VESA mount is supported on this TV with an interface size of 400 x 400 mm. The unit doesn't come with Swivel, Tilt or Pivot support.
Hardware and Audio
The chipset of LG 70UQ81006LB is powered by 4-Core CPU. However, LG didn't provide any info on the total available RAM on the TV's specsheet.
The UI on this TV is powered by webOS 22 Operating System.
For display connectivity, LG has provided three HDMI 2.0 ports on this TV.
To connect 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.
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, LG has provided 2 x 10W built-in speakers on the TV.
Speaking of power usage, on average, this TV uses about 124 watts. On standby, it uses 0.5 watts.
For powering this unit, you'll need an 220 V - 240 V/50 Hz - 60 Hz outlet.
