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.

Our Verdict

8.6 Mixed Usage

The LG E8 is an excellent TV for many different uses. It has a remarkable picture quality with perfect blacks. The image remains accurate when viewed at an angle and thus it is suitable for a large room where people will be watching from the side. It has good motion handling and good gray uniformity to please sports fans, and low input lag, good for most gamers.

Pros
  • Perfect blacks
  • Image remains accurate when viewed at an angle
  • Instantaneous response time leaves very little motion blur
Cons
  • Risk of permanent burn-in with prolonged exposure to static content
  • Brightness changes with screen content (ABL)
9.3 Movies

The LG E8 is excellent for watching movies. Especially in a dark room, the perfect blacks and the wide color gamut produce excellent picture quality with bright and vivid colors. Motion handling is excellent too, so fast moving content is clear with only a small blur trail. The E8 can clear 24p judder from the most common inputs so you should not have any issues with this.

8.2 TV Shows

The LG E8 is excellent for watching TV shows. It has remarkable reflection handling, so you can place it in a room with many small light sources without issues. It has good viewing angles so you can enjoy your favorite show without the need to sit directly in front of the TV. It has a very good smart platform with an abundance of available apps, and you will most certainly find the app that carries your favorite TV shows.

8.6 Sports

Excellent TV for watching sports. It has excellent reflection handling, so you can place it in a room with many small windows without issue. It has a very fast response time, so there is only a small blur trail in fast-content like sports. It is unlikely that you will notice any dirty screen effect due to the good gray uniformity. Finally, it is a good choice if you plan to watch the big game with a group of friends, as it has good viewing angles and the image remains accurate for those watching from the side.

8.4 Video Games

The E8 is an excellent TV for playing video games. It has very low input lag and it is very responsive to your actions. At the same time, fast content looks good with only a small blur due to the almost instantaneous response time of the TV. If you play games during the night, you will enjoy the impressive dark room performance of the TV with perfect blacks. Unfortunately, it does not support any VRR implementation to avoid tearing in very graphics intensive games.

8.7 HDR Movies

This is an excellent TV for watching HDR movies. The OLED55E8 has perfect blacks that boost the picture quality in dark rooms where HDR movies are meant to be watched. It has a wide color gamut that produces rich colors and its good HDR brightness levels make highlights pop. It has very good motion handling with very little blur in fast action movies, and 24p judder will not be an issue.

8.1 HDR Gaming

The LG E8 has an excellent performance in HDR Gaming. It is very responsive due to the very low input lag when displaying 4k @ 60Hz + HDR. The picture quality is remarkable, with perfect blacks, vivid colors and highlights that pop. When playing a fast action game you will appreciate the fast response time that only leaves a small blur trail, and if you wish to make the image even crisper you can use the optional BFI feature.

8.2 PC Monitor

This E8 has a remarkable performance when used as a PC monitor. It supports chroma 4:4:4 so the text is clear in all backgrounds. The image remains accurate when viewed at an angle so there are no uniformity issues at the sides of the screen. It has excellent motion handling and an instantaneous response time so you will not see much blur trail on your mouse. Unfortunately, the brightness lowers when large areas of the screen are illuminated, and this can be bothersome in PC usage. Finally, displaying a static content, like software menus, for a prolonged period may have a risk of burn-in.

Curved No

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.

Design
Stand

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"

Design
Back
Wall Mount VESA 300x200

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.

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.

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.

Excellent wide color gamut. The TV covers almost all of the DCI P3 space, whereas the coverage of the wider Rec 2020 is more limited. Very similar results to the B8 and the C8.

In the 'Cinema' picture mode the EOTF follows our PQ curve well until the higher luminosity levels when it starts to slowly roll off.

The EOTF in the Game picture mode and in PC picture mode are nearly identical to that of Cinema, which is good.

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.

Update 11/01/2019: Updated text to include our stance on burn-in.

Although we don't expect most people who watch varied content to have any issues, OLED TVs, such as the LG OLED E8 do have 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.

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.

Motion Interpolation (60 fps)

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 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.
