Launched in the year 2022, the 65NANO816QA is a 65" 4K TV from LG. It features a 10-bit IPS panel. The maximum resolution it can display is 3840 x 2160 @ 60 Hz with a pixel density of 68 ppi.
Picture Quality
After screen size and resolution, the next important specification of a display is its Color Reproduction (defined by its color gamut specification).
This TV doesn't come with a color gamut specification, so we have to make an assumption based on its panel type. Considering the TV features a big 65 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! It will produce accurate colors by default.
Understanding Color Gamut
Color gamut specification of a TV indicates the range of colors that the display can produce.
Put Simply, it indicates the ability of a TV to produce accurate colors. A panel with low gamut coverage will miss out on some colors (such as deep red), thus producing a "washed out" picture.
It is specified in different units - sRGB(most popular), NTSC, DCI P3 to name a few. 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.
Now, after color gamut, the static contrast of a TV also impacts its picture quality.
What is Static Contrast ?
There are 2 types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio. Dynamic doesn't matter much.
This specification defines the intensity of black levels. That is, a TV with static contrast ratio less than 1000:1 will produce black images something like this:

Apart from this, such TVs are likely be prone to backlight bleeds that will rob your experience — as shown below.

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, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV features a static contrast ratio of 8000:1., enough to display deep blacks. The panel comes with local dimming backlight which is a plus.
HDR is also supported on this TV in form of HDR10 Pro and HLG (Hybrid Log Gamma).
Coming to brightness, the peak brightness the TV can achieve is 250 nits. The backlight used on the panel is Edge LED (Local Dimming).
Gaming Performance
If you are going to use your TV other than watching videos — say as a PC monitor or for gaming purposes, you should take a TV with lowest input lag. For gaming however, both the input lag and response time impacts the performance.
Sadly, we cannot find the input lag specification for this unit. Now, 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 the TV. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
For best of both worlds, get a TV that comes with an input lag and response time of < 20ms.
Ergonomics and Dimensions
Coming to 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.
Vertically, the TV measures 65 inches and horizontally 57.17 inches.
It is 1.74 inches thick. Overall it weighs 26.6 kilograms (including stand). Without stand, it weighs 24.5 Kilograms. So plan your space accordingly.
Hardware and Audio
The TV comes with a Quad Core CPU. However, LG didn't provide any information about the RAM on the TV's specsheet.
To power its UI, the TV runs webOS 22 Operating System.
For display connectivity, there are four HDMI 2.0 ports on this TV.
To connect 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.
Wireless connectivity options on the LG 65NANO816QA include Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth 5.0 and DLNA.
Now, coming to power usage, on average, it uses around 95W. On standby, it uses 0.5 W.
Both 110V and 220V lines are supported on this unit.
