The 75QNED85UQA is a 75 inch 4K TV from LG. It was launched in 2022. It features a True 10-bit IPS panel. It can achieve a maximum resolution of 3840 x 2160 @ 120 Hz with a pixel density of 59 ppi.
After screen size and resolution, the very next specification of a display that will impact your viewing experience is Color Gamut.
LG did not provide a color gamut rating for this TV. So we have to take a guess.
Now, since the 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 will be Lifelike! Meaning it will produce accurate colors by default.
Understanding Color Gamut
Color gamut spec of a display is a measure of the range of colors that the TV can show.
A panel with poor color reproduction will produce undersaturated colors that will spoil your immersive experience.
It is specified in different units - sRGB(most popular), NTSC 1953, DCI P3 etc.
But you don't need to worry about that, here is a chart that will help you choosing a TV with good color accuracy.
Other than color accuracy, you should look at the static contrast specification as it influences the picture quality the same way.
The importance of static contrast ratio
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 dusty as shown in the below image.
As you see, this will impact your experience considerably.
Also, a TV with high constrast ratio enables you to see more details. So, resolution and static contrast ratio go hand in hand.
If given a choice, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV comes with a static contrast ratio of 8000:1., good enough to produce deep blacks. The panel comes with local dimming backlight which is a plus.
HDR is also supported on this TV in form of Dolby Vision, HDR10 Pro, HLG (Hybrid Log Gamma) and Dolby Vision IQ.
Coming to brightness, the peak brightness the TV can produce is 250 nits. The backlight used on the panel is Mini LED.
If you are not interested in gaming, 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 should take a TV with the lowest input lag and response time.
Unfortunately, we cannot find the input lag specification for this unit. Now, since this is not a cheap TV, we can expect an input lag of less than 20ms.
What is Input Lag and Why it matters ?
This lag is the latency at which key-presses/mouse movements changes the content of your display. For casual Non-FPS games, input lag doesn't matter much.
Although for better experience, get a TV that features an input lag and response time of < 20ms.
Dimensions and Ergonomics
Vertically, the TV measures 75 inches and horizontally 65.87 inches. Coming to thickness, it is just 1.77 inches thick.
Overall the TV weighs 40.1 kgs (including stand). Without stand, it weighs 39.3 Kilograms.
Speaking of ergonomics — a VESA mount with interface size of 400 x 400 mm is provided for wall-mounting. There is no Swivel, Tilt or Pivot feature support on this TV.
Hardware and Audio
The chipset of this TV is powered by Quad Core CPU. However, we could'nt find any specification about the available RAM on the TV's official specsheet.
Speaking of OS, the LG 75QNED85UQA 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 RS232 (C), 1x Cable/Antenna In (F-type female) and 1x Ethernet RJ45.
For wireless connections on this TV, you will have — a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct, Bluetooth 5.0 and DLNA.
The Audio unit of this TV is powered by 2 x 10W built-in speakers. It also comes with a built-in sub-woofer. So you don't have to invest on an external sound system.
