The LG NANO99 8k 2020 is a flagship LED TV with good overall performance, but it doesn't add much over a 4k TV since there's limited 8k content available. It's the highest model in LG's NanoCell Series, and like most of the 4k TVs in that lineup, it has an IPS panel. This means it has wide viewing angles and a low contrast ratio, so blacks appear gray when viewed in the dark. It has a full-array local dimming feature, but it performs poorly, so it's not suggested for watching movies in dark rooms. However, it gets decently bright and has excellent reflection handling if you want to use it in a well-lit room. It doesn't have any issues upscaling lower-resolution content, such as from DVDs or Blu-rays, and it displays native 8k content perfectly. Lastly, it's well-built and is compatible with LG's Gallery Flush wall-mount, similar to the LG GX OLED, but you have to buy it separately.
The LG 65NANO99UNA is a good overall TV. It performs best when watching TV shows or sports because it has wide viewing angles, decent peak brightness, and excellent reflection handling. It's very good for gaming because it has a low input lag and an excellent response time. Sadly, it doesn't perform well in dark rooms due to its low contrast ratio, disappointing black uniformity, and poorly-performing local dimming feature.
The LG 65NANO99UNA is only okay for watching movies. It has a low contrast ratio, so blacks look gray when viewed in the dark. The local dimming feature is poor and it has disappointing black uniformity. Luckily, it displays 1080p and 4k content without any issues and removes 24p judder from any source.
The LG 65NANO99UNA is great for watching TV shows. It has excellent reflection handling and decent peak brightness, so visibility shouldn't be an issue in well-lit rooms. It also has fairly wide viewing angles, so the image remains accurate when viewing off-center. Sadly, it has some uniformity issues, but this could vary between units.
The LG 65NANO99UNA is great for watching sports. It's a good choice for watching the game in a wide seating arrangement as it has wide viewing angles. It also gets bright enough to fight some glare and has excellent reflection handling. Fast-moving content looks smooth, but there's dirty screen effect in the center that can be distracting.
The LG 65NANO99UNA is very good for gaming. It has an excellent response time, a Black Frame Insertion feature to reduce motion blur, and low input lag. However, it doesn't have any variable refresh rate (VRR) support to reduce screen tearing. It's also not good for dark-room gaming because of its low contrast ratio and disappointing black uniformity.
The LG 65NANO99UNA is just okay for watching HDR movies. It displays a wide color gamut but fails to make highlights stand out in HDR. It has a full-array local dimming feature, which sadly, performs poorly. Lastly, it has disappointing black uniformity and a low contrast ratio, so blacks look gray when viewed in the dark.
The LG 65NANO99UNA is decent for HDR gaming, mainly due to its very good gaming performance. It has an excellent response time and low input lag but lacks VRR support. Unfortunately, HDR content doesn't look good because it fails to make highlights pop, has a low contrast ratio, and the local dimming feature is poor.
The LG 65NANO99UNA is a great choice to use as a PC monitor. It has an excellent response time and low input lag, delivering a responsive desktop experience. It has wide viewing angles so that the image remains accurate at the sides if you sit up close. It also has decent peak brightness and excellent reflection handling if you want to use it in a well-lit room.
The LG NANO99 8k 2020 is LG's flagship LED TV in 2020 and it sits at the top of their NanoCell Series. It's the replacement for the LG SM9970 8k and sits above the LG NANO97. There aren't many 8k TVs available and its main competitors are the Samsung Q800T QLED and the Sony Z8H.
The LG 65NANO99UNA has an outstanding style and looks like a mix between the LG NANO90 and LG GX OLED. Its thin bezels and straight feet look like other models in their NanoCell lineup, while the back looks like the GX. This is because the NANO99 is compatible with LG's Gallery Flush wall-mount, but it doesn't come with it and you have to buy it separately. Overall, it's a premium-looking TV that should please most people.
The stand is nearly as wide as the TV itself and you need a fairly deep table for the large feet. There's a bit of wobble, but overall, the stand supports the TV well.
Footprint of the 65" TV: 51.6" x 11.2".
The LG 65NANO99UNA is thin and doesn't stick out if you wall-mount it.
The LG 65NANO99UNA has outstanding build quality. It's better than most TVs in the NanoCell Series, such as the LG NANO90, and it's similar to the LG GX OLED. It's well-built all around and the frame feels very solid. There isn't much flex and doesn't feel like it would break if you drop it.
The LG 65NANO99UNA has a poor contrast ratio. This is expected from an IPS panel, but it's lower than most of LG's LED TVs. The local dimming feature improves it a bit, but blacks still appear gray when viewed in the dark. Note that contrast may vary between units.
If you want an 8k TV with a better contrast ratio, check out the Samsung Q900TS 8k QLED.
The LG 65NANO99UNA has decent SDR peak brightness. Small highlights are dim and it seems to get brighter as there are larger brighter objects. For the most part, it gets bright enough to combat glare in most well-lit rooms. If you want an 8k TV that gets significantly brighter, then look into the Samsung QN800A 8k QLED.
We tested the SDR peak brightness after calibration in the 'Expert (Dark Room)' Picture Mode with Brightness at its max, Local Dimming set to 'Medium', and Color Temperature set to 'Warm 2'.
If you want a brighter image and don't care about accuracy, then set the Picture Mode to 'Vivid' with everything else at their default settings. We reached 912 cd/m² in the 25% window using this setting.
The full-array local dimming feature is poor. It crushes small light sources and they don't pop the way they're supposed to. The local dimming feature seems to make the entire screen dimmer, and you lose details in scenes where there are both light and dark elements in the shadows. There's a bit of blooming with non-HDR content, but there's none with HDR content because small light sources are so dim. However, when there's a bigger light source, the backlight flickers, causing the screen to become brighter, and it can be very distracting. It does the same thing when there are two or more lines of subtitles, and you might think the TV is broken because of it. It seems to handle the test pattern and real content differently as zone transitions are visible in the test pattern, but not noticeable with real content. Overall, it looks better than the local dimming on the LG NANO90, but it scores the same because of the flickering issue.
We tested it with LED Local Dimming set to 'Medium'.
The LG 65NANO99UNA has decent HDR peak brightness. Like with SDR content, small highlights are very dim and don't pop the way the creator intended. The screen gets brighter as large, bright areas cover it. However, it handles our test slides differently, and real content is very dim, to the point where it's difficult to recommend this TV for watching HDR content.
We measured the HDR peak brightness in the 'HDR Cinema' Picture Mode with Contrast and Brightness each at their max and Local Dimming set to 'Medium'.
If you want the brightest image possible and don't mind losing image accuracy, we reached 964 cd/m² in the 25% window in the 'HDR Vivid' Picture Mode with LED Local Dimming on 'High'.
The gray uniformity is just okay. The edges are noticeably darker and there's dirty screen effect in the center, which can get distracting during sports. The uniformity is better in dark scenes, but the entire screen seems to be slightly blue. Note that uniformity may vary between units.
Our unit of the LG 65NANO99UNA has disappointing black uniformity. Without local dimming, the entire screen looks blue and there's a bit of clouding throughout. The image is more black with local dimming, but there's more blooming around the center cross.
The viewing angles are decent, which is expected from an IPS panel. The colors remain accurate when viewing from a wide angle, but you may notice a loss in brightness.
The LG 65NANO99UNA has excellent reflection handling, similar to the LG SM9970 8k. Visibility shouldn't be an issue even in well-lit rooms.
The out-of-the-box accuracy is great. Most colors and white balance are only slightly inaccurate, and most people shouldn't notice any issues. However, the color temperature is cold, giving the image a blueish tint. Also, gamma doesn't follow the target very well, and most scenes are darker than they should be. Note that color accuracy may vary between units.
The LG 65NANO99UNA has outstanding color accuracy after calibration. Any remaining inaccuracies can't be spotted with the naked eye. Gamma is better from before pre-calibration, except some really dark scenes are slightly over-brightened. The color temperature improved, but it's still on the cold side.

480p content, such as from cable boxes, looks good and there aren't any obvious artifacts.
The LG NanoCell 8k upscales 720p content, such as from cable TV, without any issues.
The LG 65NANO99UNA does a fantastic job at displaying native 4k content. We didn't score it a perfect 10 like most 4k TVs because it's not a pixel-perfect resolution.
Unlike the Samsung Q800T QLED, this TV displays native 8k content perfectly and there aren't any dithering issues.
The LG 65NANO99UNA has a unique subpixel structure with notches in the blue and red pixels. The LG SM9970 8k had the same thing.
The LG 65NANO99UNA has a good color gamut for HDR content. It has excellent coverage of the commonly-used DCI P3 color space, but limited coverage of the wider Rec. 2020 color space.
The EOTF doesn't follow the target PQ curve very well as most scenes are dimmer than they should be. The EOTF in 'Game' mode is very similar, except some scenes may be a bit brighter.
If you find HDR too dim, set the Picture Mode to 'HDR Standard' with Brightness, Contrast, Dynamic Contrast, and LED Local Dimming at their max settings, with Dynamic Tone Mapping enabled. This results in a much brighter image, as you can see in this EOTF. However, there's a strange increase in brightness at around the 40% stimulus mark, and this coincides with when the screen appears to flicker in HDR, as explained in the Local Dimming section.
The LG 65NANO99UNA has a decent color gamut. It displays brighter colors well but struggles with dark, saturated colors because of its low contrast ratio.
The gradient handling is good. There's minor banding throughout and it's most noticeable with green and gray. The Smooth Gradation setting doesn't do much to improve the gradients in the test pattern. It removes a lot of the banding in real content, but it may cause a loss of fine details in some scenes.
There's so sign of image retention after displaying a static image, but this may vary between units.
While some IPS panels like this have some temporary image retention, this doesn't seem to be permanent as the IPS panel in our long-term test appears to be immune.
The LG 65NANO99UNA has an excellent response time. For the most part, motion looks smooth and there should be minimal blur trail. However, there's overshoot in every transition and you may notice some artifacts.
The LG 65NANO99UNA uses Pulse Width Modulation (PWM) to dim its backlight. It flickers at 960Hz at all brightness levels on all picture modes, except for 'Game' mode, where it flickers 120Hz. The 960Hz flicker is so high that most people shouldn't notice it.
The LG 65NANO99UNA has a Black Frame Insertion feature to reduce motion blur. It flickers at 60Hz if you set TruMotion to 'User' with 'Motion Pro' enabled. It flickers at 120Hz when in 'Game' mode or with TruMotion enabled.
This TV has a motion interpolation feature to interpolate lower-frame-rate content up to 120fps, known as the 'Soap Opera Effect'. It doesn't work well with the test pattern as it looks fuzzy, but it works very well with real content. There are minimal artifacts, even in busy scenes.
See here for the settings that control the motion interpolation feature.
Due to the quick response time, there's a fair amount of stutter with lower-frame-rate content. Enabling the motion interpolation feature can help reduce this problem.
The LG 65NANO99UNA removes 24p judder from any source, such as native apps or Blu-ray players. To do so, simply enable Real Cinema.
Unlike the LG NANO90, the LG 65NANO99UNA doesn't currently support any variable refresh rate technology. However, this may come in a future firmware update and we'll retest it when we can.
