The LG OLED E8 is an excellent 4k OLED TV with a remarkable picture quality. It can display perfect blacks and is has excellent for dark room viewing. The E8 is also a good choice for rooms with wide seating arrangements as the image remains accurate when viewed at an angle. It has a wide color gamut and can display HDR content with vivid colors and bright highlights. It has excellent motion handling and a low input lag, good for most gamers and PC users. Unfortunately, just like all OLED TVs, the E8 runs the risk of permanent burn-in when it displays static images for a prolonged period of time.
The design of this year's LG E8 is an advancement over last year's E7P model, which was also excellent. LG put a lot of effort to create a TV that will look good even when it's off. The results are very good as the TV has a strong premium feel, an elegant look, and excellent overall build quality. The edges of the TV are made of glass, and the embedded soundbar is hardly noticeable, as it is thinner than last year's and it is blended in the lower bezel of the screen. The glass border also acts complementary to the stand to provide extra support for the TV.
The stand of the LG OLED E8 resembles that of the B8. The TV, however, has a thick sheet of glass onto which the screen is placed. This sheet of glass also helps support the TV and also serves the illusion that the TV is floating.
Footprint of the 55" TV stand: 24.1" x 8.9"
The back of the TV is plain. The electronics compartment is at the lower half of the back. There is very basic cable management with the use of a small removable cable guide as seen here. The 3 HDMI inputs and one USB face to the side, so you will have easy access if the TV is wall mounted.
The borders are made of glass. This design is very similar to last years E7P model.
This TV is very thin when you look at it from the side. The panel is placed on a 1/4 inch thick glass that gives off a sturdy feel and a sleek look.
The TV runs at fairly cool temperatures. You should have no issues with it.
The build quality of the LG OLED55E8PUA is excellent. The premium feel is apparent everywhere in this TV's build. You will have no issues.
The LG OLED E8 has an excellent picture quality. It can switch off individual pixels, thus producing perfect blacks which enhance picture quality, especially in a dark room. It is also well suited for large rooms with wide seating arrangements since the image remains accurate even when viewed at an angle. The TV can reach good brightness levels to overcome the glare of average bright rooms, although the ABL function prevents it from being very bright while displaying large bright scenes and this might bother some. It has a wide color gamut and displays rich and saturated colors with excellent out-of-the-box accuracy. Finally, the very good gray uniformity will not be an issue to sports fans.
The LG E8, just like all OLEDs, has an infinite contrast ratio as it can switch off individual pixels. This produces perfect blacks and is great for watching movies in a dark room.
The LG OLED55E8PUA has no need for local dimming as it can switch off each pixel individually. The video is for reference only.
Very good SDR peak brightness for the LG OLED E8.
Slightly lower than the levels measured for the B8 and the C8.
The brightness level remains relatively constant regardless of the window size, except when almost the entire screen is lit, at which point the brightness level drops due to Automatic Brightness Limiter(ABL). This is not noticeable to most people during normal use.
The menu option that controls the luminance on this LG E8 is called OLED Light.
Good HDR peak brightness but still short of the 1000-4000 cd/m² HDR is mastered for. The real scene peak brightness is, however, among the highest we've measured on OLED TVs, almost identical to the C8, and certainly brighter than the Sony A9F.
As expected, brightness levels drop gradually as the illuminated window size increases. This is due to the TVs brightness protection mechanism Automatic Brightness Limiter(ABL).
The LG OLED E8 has very good gray uniformity and most people will not notice any clouding. It is a great choice for those who enjoy watching sports as it only has a minimal dirty screen effect. In the 5% gray uniformity picture the E8 displays some vertical bands that some people might spot when watching dark scenes in a dark room. This behavior is similar to other 2018 OLEDs like the B8, the C8, and the A8F. This is hardly noticeable, and only when in a dark room.
Just like most OLEDs, the viewing angles of the E8 are very good. The picture quality remains good even when watching from the side. It is a good choice for a room with a wide seating arrangement. When viewed at an angle, colors do shift, but less than LCD TVs with a VA or IPS panel.
The LG OLED55E8PUA has perfect black uniformity. Just like all OLEDs, switching off individual pixels produces perfect blacks and thus perfect black uniformity.
Unlike the B8 or the C8, the LG E8 has excellent out of the box color accuracy. The most accurate picture mode was the 'Expert (Dark Room)'. The white balance dE and the color dE are well below the threshold of 3 where most enthusiasts would notice any inaccuracies. At the same time, the color temperature is slightly warm with an insignificant red/yellow tint. Gamma is a little higher at 2.33 and does not follow the target very well, thus shades are slightly darker.
Excellent results after calibration. The color and white balance dE were diminished below 1, making any inaccuracies impossible to spot with the naked eye. This is one of the best results we've measured until now. Gamma was also corrected and now follows the target almost perfectly. Finally, the color temperature was brought almost spot on the 6500K target.
You can see our recommended settings here.
The E8 upscales older 480p content well. The resulting image quality is not overly sharp, but all of the details are preserved well.
Full-HD content such as 1080p cable, streaming, and Blu-rays look good when upscaled. The image is clear and detailed.
In the 'Cinema' picture mode the EOTF follows our PQ curve well until the higher luminosity levels when it starts to slowly roll off.
If you find HDR content too dim, you can set the Dynamic Contrast setting to 'High', and the Dynamic Tone mapping to 'On'. These settings will raise the EOTF and brighten most HDR scenes.
Decent color volume coverage. The TV is has a wide color gamut, but loses volume at high levels of luminance. This happens because of the presence of a white subpixel in its WRGB pixel panel. This white subpixel helps boost luminance but at the same time, its mere presence de-saturates the colors produced by the other subpixels. This is more apparent at higher luminosity levels where the white subpixel intensity is higher. This results in less bright colors on the E8, just like the B8 and the C8. However, most people will not notice it.
The gradient on this TV is excellent. Our test image is displayed smoothly with no visible banding except in the dark green and gray shades, where slight banding is visible. In certain scenes, there is some banding noticeable in large areas of similar color. You can reduce banding by enabling MPEG Noise Reduction, which activates the gradient smoothing feature of the E8. This reduces the visible banding but also results in a loss of fine detail.
The LG OLED55E8PUA shows no signs of image retention except for a minor issue at the very beginning of the recovery time and this is great.
There is, however, some panel variation to be expected. Even panels of the same model may be more or less prone to image retention. This year we've tested the LG B8, the C8 and now the E8. The LG B8 and the E8 show almost no signs of image retention whereas the C8 shows slightly more signs of image retention.
Be reminded that this test is only indicative of short-term image retention and not the permanent burn-in that may occur with prolonged exposure to static images. To further investigate the issue of permanent burn-in, we are currently running a test and you can read all about it, here.
The LG E8, just like all OLED TVs, has the possibility of experiencing burn-in. Each manufacturer implements different technologies in an effort to decrease the risk of burn-in. The LG E8, just like the B8 and the C8, has three features to decrease the risk of burn-in.
We recommend enabling Pixel Refresher and Screen Shift, and setting Logo Luminance Adjustment to 'Low'.
We are currently running a test about this and you can see the results here.
With WRGB OLEDs, all four subpixels are never on at the same time. We have taken two photos to demonstrate this.
The LG OLED E8 has excellent motion handling. It has an almost instantaneous response time that leaves a very small blur trail. The TV has no visible backlight flicker but has an optional BFI feature to introduce flicker and make the image look crisper. It has excellent motion interpolation features that can also help remove the stutter that low fps content can have, due to the TVs very fast response time. The TV is also capable of removing 24p judder from most common sources. Unfortunately, it does not support any implementation of Variable Refresh Rate to enhance gaming performance.
The response time of the LG E8 is almost instantaneous. This means that there is virtually no blur, and this is great for fast-moving content as the image is crisp.
The LG E8 does not have any visible backlight flicker and this makes motion look smoother. However, this creates some persistence blur. If you want to minimize blur, you can enable the Black Frame Insertion option available on this TV.
The E8 has an optional Black Frame Insertion mode that will insert a black frame and make the image crisper. To enable BFI you must go into the TruMotion menu, select the 'User' option, and then enable Motion Pro.
TruMotion is grayed out when displaying 120Hz content.
The LG E8 has excellent motion interpolation features. It does a very good job in slow moving shots, and when there is too much motion where the artifacts would multiply, it just stops.
The TV uses the same menu options like the B8 and the C8 to control interpolation. To interpolate low fps content to 60Hz, set TruMotion to 'User' and raise the De-Judder slider. To interpolate 60Hz content to 120Hz, raise the De-Blur slider.
Motion interpolation will create some artifacts, especially in fast-moving content. If you find the artifacts bothersome, we suggest that you lower the interpolation settings. This will make the interpolation algorithm more conservative, but it will also make motion look less smooth.
The almost instantaneous response time of the E8 makes the image look crisp with very little blur. This, however, increases the stutter that can be experienced in lower FPS content like 24p. This is why the TV scores bad in the stutter test.
If you find stutter bothersome you can remove it by using the motion interpolation features that work very well on this TV.
The LG OLED E8 has a native 120Hz panel but does not support any variable refresh rate technology like FreeSync or G-SYNC.
The LG E8 has excellent low input lag which is consistent across the various input formats, except for the 1080p @ 120Hz where the input lag is even lower. The TV supports the most common resolutions, but unfortunately, it does not support 1440p. It has support for chroma 4:4:4 and 1080p @ 120 Hz, and this is good for when you use it as a PC monitor.
The input lag of the LG E8 OLED is excellent and very similar to the C8 or the B8. It is worth noting that the E8 has a lower input lag than the C8 and the B8 when displaying 1080p @ 120Hz. We do not know why and we will retest the C8 and the B8 with the new firmware to see if this remains the case.
4:4:4 Chroma is only properly displayed when the input mode (Input icon) is set to 'PC'. However, if you need low input lag while using the TV as a PC monitor, you are better off switching to game mode.
The 4:2:0 input lag bug that was noticed on the B8 has been fixed, so now 4k in HDR has the same input lag as in SDR.
The TV supports most common resolutions without any issue. Unfortunately, 1440p is not supported on this LG E8.
4k @ 60Hz @ 4:4:4 or @ 4:2:2 is only supported when HDMI ULTRA HD Deep Color is enabled.
4:4:4 Chroma is only properly displayed when the input mode (Input icon) is set to PC.
In PC Mode, Sharpness at '20' means that there is no added sharpness.
The bug that was making colors washed out in HDR when in PC mode, as seen on the B8, has now been fixed on the E8. Unfortunately, PC mode + HDR still has more banding than out of PC mode, so if you notice bad banding it may be best to change out of PC mode and into Game mode.
The LG E8, just like the other 2018 models, does not have a component input. It supports composite input using the included adapter. It has 3 USB 2.0 ports and no USB 3.0 ports, unlike last years' C7.
The TV does not have an analog audio output, so if you want to connect wireless headphones, you will need a digital to analog converter like this one.
Update 02/27/2019: While the TV doesn't support Atmos passthrough via a Dolby TrueHD carrier signal (common in Blu-ray disks), it is advertised as supporting Atmos passthrough via Dolby Digital Plus, which is the Atmos format used by some sources like Netflix; our testing confirmed this passthrough on the LG C8. We expect this to be true for the LG E8.
The LG E8 has a good sound quality. This TV gets quite loud, has a good amount of body and punch to its bass, and produces clear and intelligible dialog. However, it lacks sub-bass, so it won't be able to produce the thump and rumble common to bass-heavy music and sound effects. It also loses some of its bass and clarity when pushed to its maximum volume. For a better sound, we would still recommend dedicated speakers or a soundbar.
The frequency response is good. LFE (low-frequency extension) is at 71Hz, which is quite decent, especially for a TV. This means the bass will have a good amount of punch and body to it. However, since it lacks sub-bass, it won't produce any thump or rumble, which is common to bass-heavy music, film and video game sound effects. The response above the TV's LFE is quite even and flat, which results in clear and intelligible dialog. This TV also gets quite loud, but loses some of its punch in the bass range and clarity in the treble range when pushed to the maximum.
The distortion performance is decent. The overall amount of THD produced at 80dB SPL is above-average. This TV also performs decently at maximum volume, but could sound a little harsh and impure when pushed to the limit.
The E8 implements LG's latest technologies like LG ThinQ AI that allows you to control certain functions of your TV through speech. The new voice control features work exceptionally well and can interface with a variety of smart consumer electronics, including Google Home and Amazon Alexa. The interface can be a little confusing at first, but works well and is fast thanks to the faster α9 processor found on the E8. The TV runs on the latest version of LG's smart platform, webOS. It has a good number of pre-installed apps, and you can download more from LG's content store. The store has a large collection of apps but it is not as rich as the Play Store found on Sony TVs. The TVs remote is compact and works very well, and supports voice commands.
The webOS interface of the LG E8 is excellent. It has three sections: settings, inputs, and apps. The interface is easy to use, and navigating through the menus is fast thanks to the α9 processor. Some first-time users, however, might find it confusing.
