The LG UN8500 is an okay entry-level TV. It's sold in large sizes, from 65 to 86 inches, and mainly designed for wide seating arrangements where you sit far from the TV. Most of the sizes, including the 65 inch model we tested, have IPS panels that provide fairly wide viewing angles. It also has a low contrast ratio, so blacks appear closer to gray when viewed in the dark. It has a 120Hz panel, quick response time, and low input lag for gaming, but it doesn't support any variable refresh rate (VRR) technologies. Sadly, it doesn't display native 4k content perfectly as you may notice the pixels even when sitting at a distance. Even though it has decent reflection handling, it performs best in dim or moderately-lit rooms because it doesn't get bright enough to combat glare.
The LG UN8500 is an okay overall TV. Its IPS panel provides fairly wide viewing angles, which is great for watching TV shows or sports with a large group of friends and family. It's decent for gaming due to its 120Hz refresh rate, low input lag, and quick response time. Unfortunately, it's not good for watching movies as it has a low contrast ratio, and it doesn't display a wide color gamut for HDR content. Lastly, it's good to use as a PC monitor because it displays proper chroma 4:4:4.
The LG UN8500 is disappointing for movies. Its IPS panel has a low contrast ratio, so blacks appear closer to gray. There's no local dimming and black uniformity is poor. Fortunately, it upscales lower-resolution content well and it removes 24p judder from any source.
The LG UN8500 is decent for watching TV shows. Even though it has decent reflection handling, it's best to place it in dim or moderately-lit rooms because it doesn't get very bright. Viewing angles are fairly wide if you tend to walk around while watching TV. It upscales lower-resolution content, such as from cable boxes, without any issues.
The LG UN8500 is decent for sports. It has a great response time, but you may notice image duplication due to the backlight's 120Hz flicker. It performs well in moderately-lit rooms as it has decent reflection handling, but it doesn't get bright enough to combat a ton of glare. It has fairly wide viewing angles if you want to watch the game with a big group of friends.
The LG UN8500 is decent for video games. It has a 120Hz panel but doesn't support any variable refresh rate (VRR) technologies. Input lag is low and it has a quick response time, but you may notice image duplication with fast-moving content because of the backlight's flicker. It upscales 1080p content well, but there are some minor issues when displaying native 4k content.
The LG UN8500 is inadequate for watching HDR movies. It has a low contrast ratio, so blacks look gray when viewed in the dark. Black uniformity is poor, and there's no local dimming feature either. It doesn't display a wide color gamut for HDR content and doesn't get bright enough to make highlights pop. It also has some issues displaying native 4k content. Luckily, it removes 24p judder from any source.
The LG UN8500 is alright for HDR gaming. It has low input lag and quick response time, but you may notice image duplication due to the backlight's 120Hz flicker. Sadly, HDR content doesn't look good because it doesn't display a wide color gamut, can't get bright enough to make highlights pop, and has a low contrast ratio.
The LG UN8500 is good to use as a computer monitor. It has fairly wide viewing angles, so the image remains accurate if you sit up close. It has decent reflection handling if you want to place it in a moderately-lit room, but it doesn't get very bright. It displays chroma 4:4:4 with a 4k resolution at 60Hz, but it has a higher input lag at that resolution, so you may notice some delay when typing.
The LG UN8500 has a decent design and looks a lot like the LG UN7300. It's a simple-looking TV with thick bezels that aren't flush to the screen, so they stick out a bit. It's fairly well-built and made entirely out of plastic, but there's wobble and parts that flex easily.
The stand is almost as wide as the TV itself, so you may need a large table to place it on. It supports the TV well but doesn't eliminate all wobble. The feet seem to bend when the TV wobbles, but we don't expect this to be too much of an issue for most people.
Footprint of the 65" inch TV: 52.4" x 10.6"
The back is simple with a textured finish on the plastic. Sadly, there's no cable management.
The borders are on the thick side and they stick out from the screen a bit.
The LG UN8500 isn't very thick and shouldn't stick out much when wall-mounted.
Decent build quality. The plastic doesn't feel very premium, and the center of the back panel flexes quite easily. The TV wobbles a bit, and the feet bend slightly when it wobbles, but we don't expect this to be an issue for most people.
As expected from an IPS panel, the LG UN8500 has a low contrast ratio. Blacks appear closer to gray when viewed in the dark. Contrast may vary between units.
Note: The 82 inch model has a VA panel, so we expect it to have a much better contrast.
This TV doesn't have a local dimming feature. The video above is provided for reference only.
The LG UN8570 has disappointing peak brightness in SDR, similar to the LG UM8070. It doesn't get bright enough to combat glare in well-lit environments, so it's best to place it in a dim room. It keeps its brightness very consistent across our different test patterns, which is great, but it gets less bright in real scenes.
We tested the SDR peak brightness after calibration in the 'Expert (Dark Room)' Picture Mode with brightness at its max. If you want the brightest image possible, we were able to get 359 cd/m² in the 10% window with the Picture Mode set to 'Vivid'.
Poor HDR peak brightness. It doesn't get bright enough to make highlights pop in HDR, and even though its brightness is consistent across our test patterns, it's not as bright in real scenes.
We measured the HDR brightness in the 'HDR Cinema' Picture Mode with Dynamic Tone Mapping off. If you want the brightest image possible, use the 'HDR Vivid' Picture Mode. We were able to get 361 cd/m² in the 10% window.
The LG UN8500 has okay gray uniformity. There's some dirty screen effect in the center and significant vignetting in the corners, but these problems may vary between units. The uniformity is much better in near-dark scenes.
The viewing angles are decent. It uses an ADS panel that performs similarly to an IPS panel, but the viewing angles aren't as wide as most IPS panel TVs, such as the Sony X800H. The image remains fairly accurate when viewing from the side, and it's suitable for wide seating arrangements.
Note: The 82 inch model has a VA panel, so we don't expect it to have wide viewing angles.
The LG UN8500 has poor black uniformity. There's clouding throughout and some backlight bleed along the bottom edge, but this may vary between units.
The LG UN8570 has decent reflection handling. It handles a moderate amount of light well but it struggles in well-lit environments. Its reflection handling is a lot worse than the lower-end LG UN7300.
The out-of-the-box accuracy is mediocre, but this may vary between units. Most colors are only a bit inaccurate and the color temperature is close to the 6500K target. However, white balance is off and gamma follows a 1.9 target instead of the 2.2 target, even though the 'Gamma 2.2' setting was selected. This means most scenes are brighter than they should be.
After calibration, the accuracy is remarkable. There aren't any noticeable inaccuracies with colors and the white balance, and gamma follows the target almost perfectly. However, the color temperature is colder than before calibration, resulting in a blue-ish tint.
You can see our recommended settings here. However, we don't suggest copying these settings because we had to make aggressive changes in order to calibrate it properly. We don't know if we simply got a bad panel, and copying our settings may make your picture quality worse.
The LG UN8500 upscales 720p content, like from cable boxes, without any artifacts.
1080p content, like from Blu-ray players, is upscaled well and there aren't any artifacts.
The LG 65UN8500 displays native 4k content almost perfectly, but there are some upscaling issues. You can see the pixels from a distance that you normally don't see pixels on other 4k TVs. There's also a strange sub-pixel dithering/dimming effect when displaying solid colors. It dims every second row of green pixels, and in rows where the green pixels are dimmed, the blue pixels are brighter. Rows with brighter green pixels have dim blue pixels. You can see the pixel photo here.
It uses an ADS (Advanced Dimension Switching) panel like most other entry-level LG TVs, which is technically different from an IPS panel, but the two perform very similarly. On this panel, the green pixels have a different shape than the blue and red pixels, and they look different than the green pixels on the LG NANO81.
The green and blue pixels also have a strange dimming effect where every second row has bright green and dim blue pixels, and the other rows have dim green and bright blue pixels. You can see the pixel photo here.
The LG UN8570 has a decent color gamut for HDR content, but it fails to display a wide color gamut. The EOTF follows the PQ curve well, but most scenes are brighter than they should be. The EOTF in 'Game' mode is similar, but the image is slightly brighter.
If you find HDR content too dim, set Dynamic Contrast to 'High', which results in a brighter image, as you can see in this EOTF.
Disappointing color volume. Due to the lack of a wide color gamut and low contrast ratio, it doesn't display colors at a wide range of luminance levels.
Note: The 82 inch model has a VA panel, so we expect it to have a much better contrast, which may lead to a better color volume.
The gradient handling is decent and similar to the LG UN7300. There's visible banding in the darker shades, especially with darker gray, green, and red. The Smooth Gradiation feature doesn't affect the test pattern; however, it smooths out gradients in real content if you set it to 'High' or 'Medium', but you may lose some fine details. It smooths out some gradients even when set on 'Low'.
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 the IPS panel in our long-term test appear immune.
The LG UN8500 has a great response time. For the most part, motion looks smooth, but there's some overshoot in most transitions. There's also image duplication because of the backlight's 120Hz flicker.
The LG UN8570 uses Pulse Width Modulation (PWM) to dim its backlight. It flickers at 120Hz at all backlight settings.
There's no Black Frame Insertion feature.
This TV can interpolate lower-frame rate content up to 120fps, known as the 'Soap Opera Effect'. The motion interpolation feature is okay, but it doesn't stop interpolating even in busy scenes, which results in motion artifacts with fast-moving content. There's image duplication due to the backlight's 120Hz flicker.
To find out more about motion interpolation, and how to enable it, see here.
Due to the LG 65UN8500's quick response time, you may notice some image stutter with lower-frame rate content because each frame is held on longer.
The LG UN8500 can remove 24p judder from any source, such as native apps or Blu-ray players, which helps with the appearance of motion. For it to work, simply enable Real Cinema.
The LG UN8500 doesn't support any variable refresh rate technologies.
