The LG UP8000 is an okay budget 4k TV. It replaces 2020's LG UN7300 and UN8500, and like its predecessors, it also uses an ADS panel, which performs much like an IPS panel. This means it has wide viewing angles so that you don't lose image accuracy when viewing from the side but a low contrast ratio that makes blacks appear gray in the dark. Unfortunately, it doesn't get very bright, so it might struggle to combat intense glare, and it's certainly not bright enough to deliver a satisfying HDR experience, not to mention that it doesn't support a wide color gamut. It has a good response time; however, its 120Hz backlight flicker causes some image duplication. Lastly, while it has incredibly low input lag, its refresh rate is limited to 60Hz, and it doesn't support VRR to reduce screen tearing.
The LG UP8000 is an okay TV overall. It's best suited for watching TV shows or use as a PC monitor because it has an IPS-like panel with wide viewing angles. It's decent for watching sports due to its good response time, but there's some motion duplication caused by its 120Hz backlight flicker. It has a low input lag so that gaming feels responsive; however, the refresh rate is only 60Hz, and it lacks VRR support to reduce screen tearing. Unfortunately, it's not the best for watching movies because it has a low contrast ratio and no local dimming. It can't display a wide color gamut and doesn't get bright enough for a true cinematic HDR experience.
The LG UP8000 is mediocre for watching movies. It isn't well-suited for dark rooms because it has a low contrast ratio and no local dimming, so blacks look gray. It also stutters a bit due to its relatively fast response time. It upscales low-resolution content well, though, and it can remove judder from all sources.
The LG UP8000 is good for watching TV shows. It has wide viewing angles, so the image remains accurate when viewing from the side, which is great if you like walking around while watching TV. It handles reflections well, but it doesn't get very bright, so it's best suited to a moderately lit room. It upscales lower resolution content well without any artifacts, and its webOS smart interface is user-friendly, with tons of apps available.
The LG UP8000 is decent for watching sports. It has wide viewing angles, which is great for watching a game with a group of people. While its reflection handling is good, it doesn't get very bright, which means glare might be a problem. It has a good response time, but its 120Hz backlight flicker can cause some image duplication.
The LG UP8000 is okay for gaming. While it has incredibly low input lag and good response times, it's limited to a 60Hz refresh rate, and there's no VRR support. It's not the best for gaming in the dark because it has a low contrast ratio that makes blacks appear gray and lacks local dimming. It's also not ideal for well-lit rooms because it doesn't get very bright.
The LG UP8000 is sub-par for watching movies in HDR. It has a low contrast ratio and no local dimming, so blacks look gray when viewed in the dark. On top of that, it can't display a wide color gamut and doesn't get bright enough to make highlights pop the way they should. On the upside, it upscales low-resolution content well without any artifacts, and it can remove judder from all sources.
The LG UP8000 is okay for gaming in HDR. It has incredibly low input lag and good response times, but the refresh rate is limited to 60Hz, and there's no VRR support to reduce screen tearing. As for HDR, it can't display a wide color gamut and doesn't get very bright, so highlights don't pop the way they should. It has a low contrast ratio and lacks local dimming, resulting in blacks that look gray in the dark.
The LG UP8000 is great for use as a PC monitor. It has low input lag and fast response times to deliver a smooth and responsive desktop experience. It supports most common resolutions and can display proper chroma 4:4:4, which helps with text clarity. It has wide viewing angles, so the image remains accurate at the sides when sitting up close. It handles reflections well, but it doesn't get very bright, which means glare might be an issue in well-lit rooms.
The feet are set almost as wide as the TV, and there's no option to install them closer for smaller tables. They support the TV well, but it still wobbles a bit.
Footprint of the 65" stand: 45.8" x 10.8".
Build quality is decent. It's mostly plastic, except for the feet, which are metal. It wobbles a bit, and there's a lot of flex on the back, especially where the VESA mounting holes are. That said, it still feels fairly sturdy overall.
The LG UP8000 has a sub-par contrast ratio, typical of an IPS panel. This means that blacks look gray, especially when viewing in a dark environment. Note that the contrast ratio can vary between individual units. The 50 inch, 60 inch, and 70 inch models have a VA panel, which we expect to have much higher contrast.
The LG UP8000 has mediocre SDR brightness. It's very consistent across different content, but it isn't bright enough to combat glare in well-lit rooms.
We measured the SDR brightness after calibration in the 'Expert (Dark space, night)' Picture Mode with Panel Brightness set to max.
If you want a brighter image and don't mind losing image accuracy, set the Picture Mode to 'Vivid', Panel Brightness and Contrast to max, and Dynamic Contrast Enhancer to 'High'. We achieved 346 cd/m² in the 10% with these settings.
The LG UP8000 doesn't have a local dimming feature. The videos are provided for reference only.
The LG UP8000 has poor HDR brightness, in the same ballpark as the LG UN8500 and LG UN7300. It's nowhere near enough to make highlights pop in HDR content, and there's now some frame dimming in the 2% windows, which means that small objects in dark scenes appear dimmer. The EOTF follows the PQ curve fairly well, but most scenes are a bit too dark. If you want a brighter image in HDR, setting Dynamic Contrast to 'Low' helps a bit and results in this EOTF plot. It makes some scenes appear brighter in actual content, but some scenes also appear slightly dimmer.
We measured the HDR brightness in the 'Cinema' Picture Mode with Panel Brightness and Contrast at max.
The HDR brightness is a bit higher in the 'Game Optimizer' Picture Mode than out of it, though not by much and with the same frame dimming in the 2% windows.
We measured the 'Game Optimizer' Picture Mode with Panel Brightness and Contrast at max.
Gray uniformity is decent, although this can vary between units. The sides and corners look darker on ours, and there's also a fair amount of dirty screen effect in the middle. It's significantly more uniform in dark scenes.
Black uniformity is mediocre, although this varies between individual units due to manufacturing tolerances. The screen looks blue, and there's some clouding throughout as well as some backlight bleed along the edges.
Good viewing angles. The image remains accurate when viewing from the side, making this TV a great choice for wide seating areas. While the measurements for color washout and brightness loss seem low, they only cross the threshold slightly and remain steady until wider viewing angles.
Reflection handling is good, but it struggles a bit with direct reflections, so it isn't ideal to place the TV opposite bright lights.
Accuracy is decent out of the box. Most colors are only slightly inaccurate, but white balance is visibly off. The color temperature is very much on the cool side, which results in a blueish tint. Gamma doesn't follow the 2.2 target very well; most scenes are too dark. Note that accuracy varies between units.
Accuracy is much better after calibration. White balance and gamma are nearly perfect, and the remaining color inaccuracies aren't visible to the naked eye. The color temperature is closer to our 6500K target, but it's still on the cold side.

The LG UP8000 upscales 720p content like from cable TV with no visible artifacts.
1080p content, like from Blu-rays, is upscaled well and looks nearly as good as native 4k.
The LG UP8000 can't display a wide color gamut for HDR. It has good coverage of the DCI P3 color space used in most HDR content, but its coverage of the wider Rec. 2020 is very limited.
The LG UP80 has a poor color volume due to its limited color gamut, poor contrast, and low HDR brightness.
The LG UP8000 has excellent gradient handling. There's only a little bit of banding in the grays and greens. Setting Smooth Gradation to 'Medium' or 'High' smoothes out most of it, but it may cause the loss of fine details in some scenes.
There's no image retention on this TV; however, this may vary between units.
Although some IPS panels can suffer from temporary image retention, this doesn't appear to be permanent as the IPS panel in our long-term test is immune.
The LG UP80 has good response times overall, but it's quite slow in some transitions, causing motion to appear blurry in dark scenes. There's also some inverse ghosting due to overshoot, and the backlight's 120Hz flicker causes some image duplication.
The LG UP8000 uses Pulse-Width Modulation (PWM) to dim the backlight. It flickers at 120Hz at all brightness levels. This can cause motion duplication and may be bothersome to some people.
There's no optional Black Frame Insertion feature. The backlight always flickers at 120Hz.
The LG UP8000 can interpolate low frame rate content up to 60Hz to make motion look more fluid, also known as the 'Soap Opera Effect'. To use it, go to the Clarity settings, then set TruMotion to 'User Selection' and De-judder to max. It works fine in slow scenes, but as soon as the action gets intense, there are a lot of artifacts, including some tearing and stuttering.
The LG UP8000's relatively fast response times can cause low frame rate content to stutter a bit. If it bothers you, enabling motion interpolation may help.
Like the LG UN8500, this TV can remove judder from all sources, rare for a 60Hz TV. To remove judder, enable Cinema Screen.
