Resolution : 4k

The LG E7 OLED is a great 4k smart TV which features excellent picture quality and a well-rounded set of features that make it a versatile package. It has a dedicated soundbar for better audio capabilities, and its low motion blur and wide viewing angle help make it fit in both a dark home theater as well as a wide living room. Unfortunately, though, it suffers from temporary image retention, and it isn't quite as bright as its LED counterparts.

Design

Score components: Subjectively assigned
LG E7P Design Picture
Curved : No

The design of the LG E7 is excellent. It looks sleek from any angle, and will certainly stand out in a room. The edges of the TV are glass, and the soundbar acts as a stand to support the TV very well. It can be a little bit difficult to move due to how thin the screen is, but for most people, this is a single event.

Stand
LG E7P Stand Picture

There is a metal plate on the base of the TV which supports the TV well. The soundbar can also act as part of the stand and helps to provide extra stability. The width of the soundbar is 48.3".

Footprint of the 55" TV stand: 6.8" x 18.8"

Back
LG E7P Back Picture
Wall Mount : VESA 400x200

The rear of the TV looks great, with a textured glass finish. There is a single removable tab for cable management, which isn't as good as what is provided with some other brands such as the Sony A1E.

Borders
LG E7P Borders Picture
Borders : 0.55" (1.4 cm)

The borders look extremely thin due to the glass which sits in front of the panel. There is a fairly small gap before the picture starts.

Thickness
LG E7P Thickness Picture
Max Thickness : 2.28" (5.8 cm)

The top of the TV is extremely thin when viewed from the side, and looks just like a sheet of glass. The electronic components, power supply, and inputs are in the bottom third of the TV which is thickest.

The TV stays fairly cool because as an OLED its pixels only get as bright as they need to be. The TV does get a little warm to the touch in a few places along the back though, where the TV's internals are located.

9.0 Build Quality
LG E7P Build quality picture

The build quality of the E7P is excellent, and the whole TV feels very premium. The textured back is a nice touch, as is the 'Picture on glass'. Even the remote feels higher quality (but bigger) than other LG models.

Picture Quality

The LG E7P OLED TV has an excellent picture quality. With its perfect blacks and contrast ratio, the E7P makes for an excellent TV in your pitch black home cinema. Dark scenes reproduction is great, and this is especially noticeable in scenes with starfields. When set in a bright room, the E7P can maintain a good picture quality since it has a good SDR peak brightness and excellent handling of reflection and glare from a very bright light or window. The very good gray uniformity and viewing angle make for a great sports TV since the dirty screen effect is not noticeable, and the picture quality is maintained, even for those sitting off-center. When it comes to HDR, the E7P is amazing and HDR movies look great on it, and this is mainly due to the good HDR peak brightness (and perfect blacks) and the wide color gamut, which really helps make the content 'pop out'  in comparison with the SDR version of the same movies.

N/A

The LG E7P has an outstanding contrast ratio since, like other OLED TVs, when the TV is displaying a totally black color, the TV does not emit any light at all. This makes the E7P a perfect TV for a dark room. Blacks are deep and dark scenes look fantastic.

10 Local Dimming
What it is: The lights behind the LCD layer adapt to the picture displayed, improving the contrast ratio.
When it matters: Dark scenes viewed in a dark room.
Score components: Subjectively assigned
Local Dimming
What it is: Whether it has a feature that controls the LEDs behind the LCD layer, to match the picture and darkens the dark portion of it.
When it matters: On LED TVs only. Dark scenes viewed in a dark room.
:
No
Backlight
What it is: Configuration of the lights of the backlight.
When it matters: Effectiveness of the local dimming.
Good value: Full-array/direct lighting is better for local dimming. As for the uniformity of the screen, it depends on the implementation. Some edge-lit TVs have more uniform blacks than some full-array TVs.
:
N/A

The LG E7P does not need any local dimming because OLED is an emissive technology, so when the TV displays a pure black it totally shuts down the emissive part in that region, so no blooming or clouding is created.

Plot over time

Good SDR peak brightness. The TV's Automatic Brightness Limiter (ABL) doesn't kick in during our 50% and smaller white window tests, so the TV's brightness will only decrease during very bright scenes, or during PC monitor use with white web pages. However, when the brightness does decrease it does so drastically and it's very visible. Overall the TV is bright enough for a bright room, but may be a little dim in a very bright room.

The brightness is a little less than the LG C7 OLED, which uses the same panel, but the difference is within expected panel variance from unit to unit. However, many other competing LED TVs are much brighter, such as the Sony X930E, X900E, Samsung MU8000 and Q9F.

Plot over time

Good HDR peak brightness. Though the TV's ABL limits its brightness quite severely when very bright content is shown, these kinds of bright scenes are very rare for HDR content because it's usually mastered for an average scene brightness of 100 cd/m². Our real scene test shows that highlights in a typical scene can reach a very good 689 cd/m², though still quite short of the 1000-4000 cd/m² HDR highlights are typically mastered for.

Overall the brightness is a little less than the LG C7 which uses the same OLED panel, but the difference is within panel variance from unit to unit so both can be considered equal. The E7P fares better against its LED TV kin in HDR than in SDR, but a few LED TVs are still brighter such as the Sony X930E, X900E and Samsung Q9F.

Great gray uniformity for the E7P and this is almost the same result as we have measured on the C7 OLED. On our 50% gray test picture, besides a warmer patch near the bottom, not much uniformity issues can be noticed. Dirty screen effect is not a problem at all here and we did not notice it at all while watching sports like hockey or football.

Looking at our 5% gray uniformity test picture, some vertical lines can be noticed (looks at the picture with the light closed to see the issues better) but in person, those lines are only visible while displaying a dark uniform color and not really problematic while watching normal video content.

Great viewing angle, as expected from an OLED TV. Blacks remain perfect at an angle and brightness decreases gradually, however, color shift becomes severe when viewed at moderate angles. Overall this TV is a great choice for a room where people often view the TV from the side.

As with other OLED TVs before, the black uniformity of the E7P is flawless as when the TV is displaying a completely black image, the light emitting pixel is completely turn off and thus, no light bleeding occur at all.

When it matters: To get the most accurate picture when watching TV shows, movies or video games. This is particularly for skin tones.
Good value: 6500K
Noticeable difference: 400K
:

Out of the box and with the picture mode that brought us the closest to our calibration target, the accuracy is average. This is mostly due because the E7P gamma is tracking closer to the 2.4 target and thus, the white balance accuracy is also affected. The C7 gamma target, with the same 'Out of the box' setting, was tracking closer to the 2.0. This may be only due to panel variance and is not really a problem in itself. The color accuracy is a bit high, but can mainly be explained by the drift of the white point toward the yellow, which all other colors also have from their respective targets.

9.6 Post Calibration
What it is: TV's color accuracy after a full calibration with a spectrophotometer.
When it matters: All video on a TV that has been professionally calibrated. This isn't that useful, because most TVs can achieve a pretty good calibration if you spend enough time on them.

Color Temperature
What it is: The color temperature is a measure of the color of light. A colder color temperature (7000K) will look bluer and a warmer color temperature (4000K) will look yellower/redder. 6500K is the standard color temperature use in the TV and film industry as program, film, and photography directors usually work on monitors calibrated on the 6500k color temperature and do their color correction base on what they see on those monitors.
When it matters: To get the most accurate picture when watching TV shows, movies or video games. This is particularly for skin tones.
Good value: 6500K
Noticeable difference: 400K

After calibration, most of the issue encountered at the pre-calibration step are fixed, and the final result is an extremely accurate TV with a white balance dE of only 0.13, which is unnoticeable. The white balance control was extremely precise, and corrections were easy applied. The gamma curve is very flat and tracking very closely our 2.2 target.

The color dE was brought down to 0.99, which again is almost unnoticeable by anyone. The white point target now tracks very precisely. The color management system was helpful, but it is still not as precise and easy to use as other available color management system of other brands.

LG E7P EOTF

Excellent wide color gamut. In DCI P3 all three red, green and blue primaries are close to their targets, and in Rec 2020 only green is far from its target, as is common for modern TVs. This gamut is very similar to the LG C7, B6 and other OLEDs from last year, but not quite as good as Samsung's 2017 QLED TVs like the Q7F.

The TV's EOTF in the HDR Cinema Home picture mode undershoots the PQ curve quite a bit, making most scenes more dim than intended. The EOTFs in Game and PC modes are similarly dim. The picture quality still looks very good in a dark room because of the TV's infinite contrast ratio, but in a bright room HDR content will look too dim. Setting 'Dynamic Contrast' to Medium or High can alleviate this somewhat, at the cost of less accurate picture quality.

Update 11/10/2017: LG's new Active HDR feature (Dynamic Contrast: Low) improves the EOTF considerably, so we recommend enabling it. Unfortunately Active HDR doesn't work in Game or PC mode.

Decent color volume. The TV's infinite contrast ratio helps it extend its wide color gamut to extremely low brightnesses, but at high brightness the TV's RGBW pixel structure prevents it from making saturated colors nearly as bright as it can make pure white. This color volume is a little different than that of the LG C7, but the difference is within expected panel variance from unit to unit so both can be considered equal.

The E7P has a great result on our gradient test. It can display our gradient test image very good and without any visible 8-bit banding, which is great for HDR content. Like the C7, light shade is almost spotless with only some little color issues in the darker color and grayscale. Banding in movies is not really more a problem here than on the C7.

Update 2017-11-07: Note that when the TV is set to 'PC' mode, via the input menu, the banding is much more visible, and this for all picture modes.

The LG E7P did show some image retention on our image retention test but unlike the 2016 LG OLED TVs, it's far better and is very similar to the LG C7. The retention is not very strong right after the 10 minutes burn-in scene (as seen in the above picture) and after 4 minutes, it is almost not noticeable. After 6 minutes no retention is visible and this, when compared to the 2016 OLED TVs, is a big improvement.

Note that this test only tests the short term image retention and not the permanent burn-in that may occur with a longer exposition to static images. We are currently running a burn-in test that should give us clue on how each type of TVs respond to a longer exposure to static image and you can read more on this test here.

Note that there is a variation in temporary image retention between units.

1.0 Permanent Burn-In Risk
What it is: The risk of developing a persistent image retention, also known as burn-in, after being exposed to a static image for a prolonged time

Motion

The motion handling of the E7P is excellent. It has an almost perfect response time, which results in no visible trails following moving objects. It uses DC dimming, so the screen doesn't flicker by default, but unfortunately, BFI cannot be enabled to clear up motion. Movies from a DVD or Blu-ray player can be played smoothly, but movies from cable or satellite boxes show some judder, which is not very noticeable for most people. The TV is able to interpolate content up to its native 120Hz refresh rate and can produce a strong soap opera effect.

Like other OLED TVs, the LG E7P has a nearly perfect response time, resulting in almost no visible blur following moving objects, which is excellent when watching fast-paced content. The downside of this is that low fame rate content such as movies may appear to stutter, because there is no motion blur to smooth transitions between frames.

10 Flicker-Free
What it is: How noticeable flicker is on the screen, when all optional flicker has been disabled.
When it matters: All usages, but particularly when viewing fast motion (such as in sports and video games) or when using the TV as a PC monitor.

:
0 Hz

Like all OLED TVs, the E7P doesn't flicker to dim, and instead shows each image for a full frame. Some flicker is detectable in our measurements but shouldn't be visible during normal usage. The absence of visible flicker makes motion appear slightly smoother, but results in some persistence blur.

0 Black Frame Insertion (BFI)
What it is: How effective the TV's flickering capabilities are in making motion look clearer, when flicker is desired.
When it matters: When flicker is desired by the user. Flicker is especially useful to make motion look clearer when viewing 60 fps content (sports, video games) and when using motion interpolation.

The LG E7P has a 120 Hz panel and can interpolate lower frame rate content to 120 fps, which greatly improves motion. Unfortunately the interpolation isn't as good as on some other TVs: the motion stuttered at times during normal content, especially cartoons, and artifacts would appear in rare cases. This behavior is similar to the LG C7. To enable motion interpolation (soap opera effect) set 'TruMotion' to 'User'. To interpolate a 30fps source increase 'De-Judder', and to interpolate 60fps content increase 'De-Blur'.

Update 11/13/2017: The motion interpolation performance has been clarified in the text.

Like other OLED TVs, the E7P has stutter which is especially noticeable with low frame rate content such as movies. This is a result of the very fast response time, so each frame is shown as a static image for some time. Unfortunately there is no way to fix this without adding additional frames through motion interpolation (the soap opera effect).

The E7 OLED is able to play 24Hz movies from any source (Blu-rays, DVDs and HTPCs) without judder. For 24p sources turn on 'Real Cinema' and set 'TruMotion' to cinema with both sliders set to 0, and this won't add the soap opera effect. For a 60p/60i source such as HTPC or cable box, only turning on the 'Real Cinema option is necessary.

When it matters: When gaming with a device which supports variable refresh rates, such as the Xbox One X or a PC.
:
N/A

Excellent low input lag, which should please all but the most competitive gamers. Both Game mode and PC mode have low input lag; all picture modes in PC mode have the same low input lag. 4:4:4 color is only shown properly in PC mode (aka when the input's icon is set to 'PC'). Overall the input lag is similar to the LG C7 and most Samsung TVs, and far better than most Sony TVs, but a little worse than the LG SJ8500 and TCL P607.

What it is: How well and accurately the audio is reproduced.
When it matters: When a good and accurate sound reproduction is needed.
Score components:

The LG E7P sounds better than average thanks to its built-in soundbar. Not only is the signature decent, the properly directed speakers help create a stereo effect. It isn't good enough replace a set of dedicated speakers, but it would suffice for most people.

Update 10/23/2017: We've re-tested the E7's audio capabilities and discovered that it offered better performance with its room correction feature disabled.

The E7P's remote has almost the same button configuration as the C7 and SJ8500's smart remote, but with a much longer and thinner body. The remote is very large and has appreciable weight, but it offers a few great smart features in return. The highlight of the remote is the pointer: when the remote is pointed at the TV a cursor on the TV follows its movement, allowing menu items to be selected directly and avoiding clicking through the rest of the menu. The select button on the remote also doubles as a scroll wheel, also speeding up menu interaction. The remote has a microphone for voice search, which mostly just searches for content from sources like YouTube and Netflix, but it can also be used to quickly launch apps and inputs.

Differences between Sizes and Variants

We tested the 55" (OLED55E7P). For the most part, we expect our review to be valid for the 65" (OLED65E7P).

If someone comes across a different type of panel or if their LG OLED 55E7P doesn't correspond to our review, let us know and we will update the review.

LG E7P Group Shot Picture
Top left: Sony X930E (XBR55X930E). Bottom left: LG C7 (OLED55C7P). Middle: LG E7P (OLED55E7P). Top right: Sony A1E (XBR55A1E). Bottom right: Samsung Q8C (QN55Q8C).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The LG E7P is an excellent 4K TV, but its premium pricing makes it hard to recommend over LED TVs from competing brands as well as cheaper LG OLEDs.

LG B7A
55" 65"

The LG E7P has a very similar performance to the LG B7A. The two TVs score almost the same in most of our tests. The main difference is the presence of a dedicated soundbar found on the E7P to improve sound performance and the temporary image retention where the E7P is doing better, but this can be attributed to panel variance.

LG C8
55" 65" 77"

The LG C8 is slightly better than the LG E7P. The LG C8 has a black frame insertion (BFI) feature that can help clear up blur in fast-moving content. Also, the LG C8 can get brighter, and this matters if you watch a lot of TV shows in a bright room. On the other hand, the LG E7P has a dedicated soundbar and somewhat better input lag when playing HDR games and can remove 24p judder from any source.

LG B8
55" 65"

The LG E7P has a very similar performance to the LG C7. They have very similar scores in all our test, and the main difference is the presence of a dedicated soundbar on the E7P.  Also, the performance of our temporary image retention test was slightly better on the E7P, but this can be attributed to panel variance.

LG C7
55" 65"

The LG B8 is marginally better than the LG E7P. The LG B8 supports a black frame insertion (BFI) feature that can make fast content crisper. On the other hand, the LG E7P has a dedicated soundbar and a better input lag when playing HDR games.

Sony X930E
55" 65"

Part of the high-end of Sony's range of LED TVs, the X930E is one of the best 4k TVs currently available. Compared to the E7, it gets notably brighter. Overall though, its performance falls a bit short due to its much narrower viewing angle and higher motion blur. If you don't mind the large price difference, the E7 is the better TV of the two.

Sony A1E
55" 65" 77"

The A1E is Sony's only OLED TV and it directly competes with the LG E7P. They both have similar prices, have expanded audio capabilities and a striking design. Their performance is almost identical, so pick whichever of the two you prefer the design and smart features, as they are the biggest difference.

Samsung Q8C
55" 65" 75"

The Samsung Q8C sits in the middle of the Korean giant's QLED line of LCD TVs. Its standout feature is the very large color volume giving it impressively vibrant colors when used with HDR content. Overall though, its performance leaves a lot to be desired compared to the LG E7. Even when considering the considerable difference in price, the cheaper Q8C isn't a great alternative to the E7P.
