The LG NANO80 is a lower-midrange 4k TV with okay overall performance. It's a larger variant of the LG NANO81 and offers similar performance and features, except there isn't any local dimming. It has an IPS panel with fairly wide viewing angles, but that comes at the cost of its low contrast ratio, and blacks appear gray when viewed in the dark. Despite missing many gaming features, it has a decent response time and incredibly low input lag, so it's a good choice for casual gaming. Unfortunately, HDR content doesn't pop how it should because it doesn't get bright in that mode, but it displays a wide color gamut for HDR content. Lastly, LG's WebOS is easy-to-use and the LG Content Store has a great selection of apps available to download.
The LG NANO 80 is an okay TV for most uses. It's decent for watching TV shows or sports and performs best in wide seating arrangements due to its wide viewing angles. It's good for gaming thanks to its incredibly low input lag and decent response time. However, it's not a good choice for watching movies in dark rooms because it has a low contrast ratio and there's no local dimming feature.
The LG NANO 80 is disappointing for watching movies. It has an IPS panel with a low contrast ratio and no local dimming feature, so blacks appear closer to gray when viewed in the dark. Fortunately, it upscales 1080p content well and removes 24p judder from Blu-rays.
The LG NANO 80 is decent for watching TV shows. It has fairly wide viewing angles and the image remains accurate even if you walk around while watching. It also upscales lower-resolution content without any issues. Sadly, it doesn't get very bright and has only decent reflection handling, so it's best to avoid using it in well-lit rooms.
The LG NANO 80 is decent for watching sports. It has a decent response time that results in minimal motion blur, but you may notice image duplication due to the backlight's flicker. It has wide viewing angles if you want to watch the game in a wide seating arrangement. Unfortunately, it's best to avoid using it in a bright room as it has a disappointing peak brightness and only decent reflection handling.
The LG NANO 80 is good for video games. It has incredibly low input lag and a decent response time, but you may notice image duplication because of the backlight's 120Hz flicker. Unfortunately, it lacks many features like variable refresh rate support or a Black Frame Insertion feature.
The LG NANO 80 is disappointing for watching HDR movies. It displays a wide color gamut for HDR content and has decent gradient handling, but it doesn't get bright enough to make highlights pop. Also, it has a low contrast ratio and there's no local dimming, so it doesn't perform well in dark rooms.
The LG NANO 80 is okay for HDR gaming, mainly due to its good gaming performance. It has incredibly low input lag and a decent response time for a responsive gaming experience. It displays a wide color gamut for HDR content, but it has low peak brightness, no local dimming feature, and a low contrast ratio.
The LG NANO 80 is good to use as a PC monitor. It has fairly wide viewing angles, so the image remains accurate if you sit close. It has incredibly low input lag and displays chroma 4:4:4, which is important for reading text. Unfortunately, even though it has decent reflection handling, it doesn't get bright enough to combat glare in well-lit rooms.
The LG NANO80 is an entry-level TV in LG's NanoCell lineup and is a variant of the LG NANO81. It's sold at certain retailers for Black Friday, such as Best Buy. It's a new model in 2020 and competes with other large, budget-friendly options such as the Samsung TU6980, LG UN8500, and the TCL 4 Series 2020.
The LG NANO80 has a decent, yet simple, design. It doesn't have a premium look like other models in the NanoCell Series, such as the LG NANO81, and looks more like the LG UN7000. It has somewhat thick bezels and the stand consists of two feet instead of the center-mounted stand found on higher-end models.
The stand is made of metal feet and it's almost as wide as the TV itself, so you need a large table to place it on. Sadly, the feet can't be placed inwards to accommodate smaller tables. The stand supports the TV well, but there's still some wobble.
Footprint of the 75" inch TV: 62.9" x 13.1".
The back of the TV is made of smooth metal and doesn't have any patterns etched into it. Sadly, there's no cable management.
The TV itself is fairly thin, but it may stick out a bit when wall-mounted due to the bulge at the bottom.
The LG NANO80 has a decent build quality. It's mainly metal and feels fairly sturdy. However, the back where the inputs are flexes a bit, and the TV wobbles slightly, but it's not bad.
The LG NANO80 has a mediocre contrast ratio, which is expected from an IPS panel. Blacks appear closer to gray when viewed in the dark, and there's no local dimming feature to further improve the black level.
Even though LG advertises that this TV has a local dimming feature, it doesn't have one. The video above is provided for reference only.
This TV has disappointing SDR peak brightness. It maintains its brightness consistent across different content, but it doesn't get bright enough to combat glare in well-lit rooms. If you want something brighter, check out the LG UN6970.
We measured peak brightness after calibration in the 'Expert (Dark Room)' Picture Mode with Backlight at its max and Color Temperature set to 'Warm2'. We got the brightest image possible using these settings, as seen in the 2% window.
The HDR peak brightness is poor. It doesn't get bright enough to make vivid colors stand out in HDR and small highlights are dim due to the TV's frame dimming.
We measured HDR peak brightness in the 'HDR Cinema' Picture Mode with Backlight and Contrast each at their max and Color Temperature set to 'Warm2'. Once again, we got the brightest image possible with these settings, as seen in the 10% window.
Our unit has okay gray uniformity, but this may vary between units. The edges of the screen are visibly darker and there's dirty screen effect in the center, which can be distracting during sports. Uniformity is much improved in near-dark scenes.
This TV has fairly wide viewing angles, which is expected from an IPS panel. It's suitable for wide seating arrangements as the image remains accurate when viewing from the side.
This TV's black uniformity is unremarkable, but it's better than other LG TVs we've tested, such as the LG NANO81. There's some clouding throughout and there's backlight bleed near the bottom right corner. Note that black uniformity may vary between units.
The LG NANO 80 has decent reflection handling. It performs well in moderately-lit rooms, but the reflections may be too distracting with direct sunlight on it.
The out-of-the-box accuracy is good, but this may vary between units. Most colors and white balance are only slightly inaccurate, and it shouldn't be too noticeable for most people. However, the color temperature is much colder than our 6500K target, and gamma seems to follow a 2.0 target instead of 2.2, so most scenes are brighter than they should be.
The color accuracy after calibration is outstanding. Any remaining inaccuracies with colors and white balance can't be spotted by the naked eye. Gamma follows the target almost perfectly, and the color temperature is much closer to the 6500K target, but it's still on the cold side.
You can see our recommended settings here.
This TV upscales 480p content, such as from DVDs, without any issues.
The LG NANO 80 upscales 720p content, such as from cable boxes, well and there aren't any artifacts.
1080p content, such as from Blu-ray players, looks almost as good as native 4k content.
This TV displays native 4k content perfectly and there aren't any obvious issues.
Like the LG UN7300, the LG NANO 80 uses an ADS (Advanced Dimension Switching) panel, which behaves like an IPS panel.
The LG NANO 80 has a good wide color gamut for HDR content. It has excellent coverage of the commonly-used DCI P3 color space, but its coverage of the wider Rec. 2020 color space is limiting.
The EOTF follows the target PQ curve fairly well until it rolls off at its peak brightness. The image is similar in 'Game' mode, as you can see in this EOTF.
If you find HDR too dim and want the brightest image possible, enable Dynamic Tone Mapping, set Dynamic Contrast to 'High' with Brightness and Contrast at their max. This results in a slightly brighter image, as you can see here.
This TV has an unremarkable color volume. It's limited by its low peak brightness and low contrast ratio, and it can't display dark, saturated colors well.
The LG NANO 80 has decent gradient handling. The most noticeable banding is with grays and greens, and there's some with reds and blues as well. Setting the Smooth Gradation feature to 'Medium' or 'High' doesn't affect the test pattern, but it really smooths out gradients in real content, at the cost of losing fine details.
There are no signs of temporary image retention, but this may vary between units.
Although some IPS panels can suffer from temporary image retention, this doesn't appear to be permanent as seen in our long-term test.
The LG NANO 80 has a decent response time. There's some overshoot in darker transitions, so you may notice motion artifacts in dark scenes. You also may notice image duplication due to the backlight's flicker.
This TV uses Pulse Width Modulation (PWM) to dim its backlight. It flickers at 120Hz at all brightness levels.
There's no Black Frame Insertion feature and the backlight always flickers at 120Hz.
The LG NANO 80 can interpolate lower-frame rate content up to 60fps. It performs somewhat well and smooths out motion in quiet scenes, but there are more artifacts in busy scenes. You also may notice image duplication due to the TV's 120Hz flicker.
See here for the settings that control the motion interpolation feature.
Due to the slower response time, there's not much stutter with lower-frame rate content.
This TV removes judder from native 24p sources, such as native apps or Blu-ray players. For it to work, simply enable Real Cinema.
The LG NANO 80 doesn't support any variable refresh rate technology.
This TV has incredibly low input lag, whether you're gaming in 4k or 1080p, as long as you're in 'Game' mode. It also has an 'Auto Low Latency Mode' that automatically switches the TV into 'Game' mode when a game from a compatible device is launched, ensuring the lowest input lag possible. For it to work, simply enable Instant Game Response.
