LG OLED E8 vs OLED E7

LG OLED E8 is a “Picture on Glass” model of LG’s 2018 4K HDR OLED TV while LG OLED E7 is the predecessor, one of the “Picture on Glass” models of LG OLED TV that released in 2017. Although LG E7 is older model, but some merchants still sell it. In the market, both of them equally come in 2 screen sizes only, which are 55 Inch (OLED55E8PUA vs OLED55E7P) and 65 inch (OLED55E8PUA vs OLED65E7P). With the same screen sizes, OLED E8 is sold hundreds dollar more expensive than OLED E7, but this is more due the price of E7 has dropped a lot sinceLG E8 is launched, while the price of E8 is still nearly full price. But of course, their prices certainly are not fixed and could still change and usually will tend to drop with the passage of the time, particularly the price of OLED E8 as a newer model. So, what new features are brought by OLED E8 and which is a better choice between them?

The differences between LG OLED E8 AND OLED E7

Design

LG OLED E8 vs OLED E7 Design

Although both LG OLED E8 and OLED E7 equally come with a design called “Picture on Glass”, but there are some changes brought by OLED E8 over OLED E7 the predecessor. One of the major changes is at the bottom side of the frame where OLED E8 now lacks bold integrated sound bar like on OLED E7 the predecessor. Additionally, if on LG E7, there are glass protrusions on all sides of its frame, while on LG E8, we will found a more extended glass protrusion at the bottom side of the screen only but it is more extended.  Instead of glass protrusions at the three sides of OLED E8’s frame, there is a smart black finish on the outer side. Meanwhile, for supporting their panel, both of them equally have simple and metallic stand, but they have a bit difference in shape. On OLED E7, the stand attaches directly on its radiator grid style sound bar, while on OLED E8, the stand is attached directly on the glass protrusion. This gives the impression as if the screen is floating in the air. Overall, LG E8 has glamorous design, but without radiator grid style sound-bar at the bottom of the screen, in my personal opinion, its design is not as glamorous as LG E7 the predecessor.

Processor

Alpha 9 Intelligence Processor

As we see on comparison table above, LG OLED E8 and OLED E7 are powered by different processor. For this case, LG OLED E7 is powered by M16P processor while LG E8 is powered by Alpha 9 Intelligence Processor. According to LG’s claim, Alpha 9 has 35% better performance than M16P for both CPU and GPU.  One of the advantages of Alpha 9, in removing images noise, it uses four-step images reduction by applying de-contouring filter. This makes quantization errors in the source content in processing images can be minimized. Meanwhile, the M16P processor only uses two steps in processing images that makes more prone to quantization error that caused posterization artifact. The result, with Alpha 9 processor, LG OLED E8 should have smoother gradation than OLED E7 the predecessor, particularly when playing low bit rate content.  Additionally, the use of Alpha 9 processor also makes LG E8 has a b it better performance than LG E7 in enhancing depth and sharpness. Not even just that, the use of Alpha 9 processor is also impacted on its smart TV performance where its performance is a bit more responsive and faster than OLED E7 the predecessor.

The Level of Tru Color Accuracy Technology

As a newer model, LG OLED E8 has higher level Tru Color Accuracy technology where it comes with Pro Version while OLED E7 the predecessor comes with standard version.  The difference between them is about their 3D Cube LUTs sizes where the Pro version has 33 x 33 x 44 of 3D LUT sizes that means it has 35,937 reference colors data points of color correction, while the Standard version has 17 x 17 x 17 of 3D LUT that means it only has 4913 reference colors. Both LG OLED E7 and OLED E8 may equally support 10 bit color that means they can produce about 1.07 billion of shades colors. With more color references data points, LG E8 has less color interpolation that should makes it can produce more accurate color than LG E7 the predecessor, particularly after calibration. .

The level of Ultra Luminance Technology

ultra luminance review

Like on their Tru Color Accuracy technology, they also have a difference in the level of their Ultra Luminance Technology. For this case, LG OLED E8 also comes with Pro Version while OLED E7 comes with standard version. The result, with higher level of Ultra Luminance technology, LG E8 should have brighter peak brightness than OLED E7. And this impact will be more noticeable when they are playing HDR contents in a bright room.

Black Frame Insertion

Both LG OLED E7 and E8 may equally have outstanding pixel response time that make them can minimized motion blur excellently. But this is only impacted on the blur that caused by pixel response time while motion blur that caused by persistence may still visible, particularly when they are playing 60 fps contents like sports or video games. For solving this issue, LG OLED E8 now already has an optional BFI (Black Frame Insertion) mode that will make backlight flicker at 60 Hz. By activating this feature, this will makes motion looks clearer, but on the other hand, this will cause backlight flicker on the screen.  On the other hand, LG OLED has not this feature.

HFR (High Frame Rate) Support

LG E8 also has an ability to process native 120 HZ contents or called “HFR” that allows it is able to play 120 Hz contents. On the other hand, LG OLED E7 the predecessor doesn’t has this ability. Additionally, they also have a difference in the version of HEVC decoder. With Main10 Profile at level 5.2 of HEVC decoder version, OLED E8 is able to decode HEVC content up to 4K resolution at 120 Hz. On the other hand, LG E7 has Main10 Profile at level 5.1 version that means its ability in decoding 4K HEVC files only at 60 HZ. But unfortunately, the ability of LG E8 in processing HFR is not supported by adequate HDMI connection. Since it HDMI ports only support HDMI 2.0 and don’t support HDMI 2.1 full bandwidth, its HDMI ports doesn’t have sufficient bandwidth to pass-through HFR content. This means, OLED E8 can only play HFR content via USB device and doesn’t accept HFR via HDMI.

Smart TV

Both LG OLED E7 and OLED E8 may be equally featuring WebOS as their version but for this case, they come with different version. For this case, LG E8 comes with 4.0 version while LG E7 comes with 3.5 version. In term of appearance and menus, there are not many changes brought by the newer version over the older version.  But even so, by the support of Alpha 9 processor, this makes performance of LG E8 is a bit faster and more responsive LG E7. The major highlight brought by 4.0 version, it now has been integrated with LG Ai ThinQ, a smart home assistant by LG. In addition to it allow you to control and monitor your other ThinQ compatible devices via your LG TV, it also makes its voice navigation is much better.

The Similarities

LG OLED E8 as a newer model may bring some major changes over OLED E7 the predecessor, but in some aspects, they still have similarity in technologies and features. Equally coming with OLED panel, both of them are also able to produce perfect black level and infinite native contrast ratio. Additionally, equally coming with 4 sub-pixel technology (RGBW), their panels are also equally able to produce wide color gamut and good color volume. HDR formats which supported by them also the same where they already support most of HDR format including HDR10, Dolby Vision, HLG, and Advanced HDR. The only HDR format they don’t support is HDR10+ that developed by Samsung and its alliances and has the same method to Dolby Vision in sending metadata. Additionally, they also equally have Tru 4K Ups-Scaler engine that can do a great job when up-scaling non 4k contents to 4K resolution.

As their controller, both of LG OLED E7 and OLED E8 also equally equipped with the excellent LG’s magic remote. There are not many changes between them and they also have similar features. But since the 2018 model comes with ThinQ AI, the remote of LG E8 has better voice navigation than the remote of LG E7. But even so, this is more due by ThinQ AI than their own performance. And for connecting with other devices, both LG OLED E8 and OELD E8 are also equipped with the same inputs/outputs like 4HDMI ports, 3 USB ports, etc.

LG OLED E8 vs OLED E7 Performance

Picture Quality

Overall, both LG OLED E8 and OLED E7 have excellent picture quality. As we know, one of the aspects that have major impact to the picture quality is black level and contrast ratio. The deeper black level produced, the picture displayed produced by a TV will look better, particularly when it is displaying dark scene in a dark room. The result, dark scene of images displayed on their screen looks really excellent, no matter the light condition of a room where they are used. Additionally, perfect black level produced by them is also dark enough to reveal details of images in dark scene of HDR images excellent, makes shadow details of HDR images can be shown excellently like the content creator’s intended.  Meanwhile, the use of Alpha 9 makes LG E8 can minimize noise more than the predecessor. The result, noise in dark scene is less noticeable on the screen of LG E8 than E7 the predecessor.  But even so, overall, both LG OLED E7 and E8 are able to do a great job in showing dark scene, makes dark scene looks excellent in a dark room, particularly when they are playing HDR images.

oled-black-level

As we have discussed slightly above, coming with higher level of Ultra Luminance, LG OLED E8 can produce brighter peak brightness than OLED E7 the predecessor, no matter they are playing SDR or HDR content. When playing SDR content, except 100% bright window, peak brightness of OLED E7 is a bit less than 400 nits while OLED E8 is a bit brighter than 400 nits. This means, their peak brightness actually is equally bright enough to fight the glare when they are set in a bright room. Combined to its excellent performance at dealing with reflection, this makes the picture displayed on their screen looks remain excellent in most bright room. But a bit unfortunate, when showing a scene with all objects are bright like outdoor bright scene, their peak brightness dims significantly to below 200 nits due it is limited by ABL (Automatic Brightness Limiter). Fortunately, in a movies, a scene with all objects are bright is rare, so this should not be a major problem for both LG E7 and E8. Meanwhile, when playing HDR contents, both LG OLED E7 and OLED E8 even can produce far brighter peak brightness, even on small white window, LG E8 can reach peak brightness up to nearly 900 nits, while OLED E7 is nearly 700 nits. The result, on the screen of OLED E8, highlight of HDR images can be shown brighter than on the screen OLED E7. On the other hand, although not as bright as OLED E8 the successor, peak brightness of LG E7 is also excellent for OLED TV. The excellence offered by them, since they have self-lighting pixel, there is almost no “blooming” visible when they are showing a scene with small bright object in a dark background. But even so, since their peak brightness is still less than 1000 nits, this certainly makes them cannot show highlight of HDR images brighter than 1000 nits like the creator intended. As the note, some premium LED TVs like Samsung Q9FN or Sony X930E have far brighter peak brightness than them and are able to show highlight of HDR images at 1000 – 4000 nits of brightness range like the creator intended. But even so, although their performance is not as great as premium LED TVs in showing bright scene of HDR images, both LG E8 and E7 offer great job in showing HDR images in just different way like better shadow details or blooming-free.

Meanwhile, both LG OLED E7 and E8 also have excellent wide color gamut, only a bit worse than Samsung QLED TV as a TV with the best color gamut. Both of them even can cover more than 96% of DCI P3 color space that means it is great for HDR contents, particularly for those which mastered in DCI P3 like HDR 10 contents. Additionally, both of them also have good color coverage in Rec.2020, makes color of HDR images mastered in Rec.2020 like Dolby Vision content also can be well produced. In addition to excellent color gamut, overall, their color volume is also good.  But even so, since their peak brightness is limited by ABL, extremely bright colors cannot be shown at their proper brightness. This makes very bright colors cannot be shown as saturated as darker colors.  Fortunately, this will be noticeable when they are showing extremely bright highlight, so this should not be a problem for them.  But overall, except extremely bright colors, they can show its wide color gamut at their entire brightness range. They even can show deeper colors better than LED TVs including Samsung QLED TV. The result, colors of HDR images displayed on their screen looks very accurate. In addition wide color gamut and good color volume, both LG OLED E8 and E7 also have excellent color gradient.  Since both of them already support 10 bit depth of colors, they are able to produce more than 1.07 billion shades of colors. The result, color gradient of images displayed on their screen looks very smooth, particularly when they are playing HDR content. Although at certain color, there are still some little imperfections, but this should not be a problem for normal content.

Side Viewing Angle

OLED TV vs LED TV Viewing Ngle

As we know, side viewing angle becomes one of the excellences of OLED TV over LED TV.  If on the screen of LED TV, the picture usually will look worse when viewed from the side, on their screen, the picture displayed will look more consistent, no matter the angle you view from. Like on LED TV, started at certain angles, colors of images displayed on their screen may still shift, but at wider angle, the color shift is not as significant as that happens on LED panel. The excellence, black level and brightness can be maintained at wide angle, even at extremely wide angle. The result, no matter from the angle you watch TV, the picture displayed on their screen will look remain good. The great performance of both in maintain picture quality from the side angle even is far better than IPS TV that also designed for delivering good side viewing angle coverage.

Motion handling and 24p Playback

In addition wide viewing angle coverage, the other excellence offered by OLED TV including LG E8 and E7 over LED TV is its excellent response time. Both LG OLED E7 and OLED E8 have excellent pixel response time, far lower than the lowest reached by LED TV. This means it is great for handling motion blur. As the result, when they are playing fast moving images like sport, fast movies, or others, the picture produced looks very smooth and clear with almost no motion blur. Following fast moving object, there is only an extremely short ghosting trail where most people may not notice this much. The blur that may still be visible is more caused by persistence than pixel response time. Additionally, since both of them don’t have backlight, this allows them has backlight flicker-free.  Flicker free may makes the picture looks smooth, but on the other hand, this will makes some persistence blur. Until here, their performance in handling motion blur and flicker is similar. But the advantage offered by OLED E8 than OLED E7 the predecessor, it now has a 60Hz BFI (Black Frame Insertion) mode. You can enable this feature by set on “Motion Pro” on its picture setting. When this feature is enabled, the TV will make backlight flicker at 60 HZ. This is very useful to make motion looks clearer, particularly when playing 60 fps content like sports or video games, but on the other this will make you can see flicker on its screen. For you who are not too comfort with blur, you can enable this feature, but otherwise, for you who are not too comfort with blur, you can disable this feature.  Meanwhile, LG E7 doesn’t has this feature that certainly makes it doesn’t have an ability in minimizing blur that caused by 60 fps persistence.

LG OLED TV Motion Blur

When playing 24p movies, LG OLED E7 can do a better job than OLED E8, particularly when playing 24p movies via 60i signal like movies from satellite TV. When playing movies with this frame rate, LG E7 is able to show them with judder-free, while OLED E8 cannot completely eliminate the judder. The inability of OLED E8 in removing judder at 60i signal actually is not usual, so we expect there will an update firmware of OLED E8 in future that will fix this issue. On the other hand, most people don’t notice judder much, so this should not be a problem for them. Meanwhile, except via 60i signal, both of them equally can do a great job. This means, no matter the source is native 24p videos like Blu Ray or DVD’s movies, via 60p signal like movies from streaming devices, or via streaming apps like Netflix, Amazon Videos, and others, all of them can be shown smoothly and clearly with judder-free on their screen. For removing judder without adding “soap opera effect” you just need to set “Tru Motion” option to “User” and set both the “De-Blur” and “De-Judder” to “0”.

Inputs/Outputs

There no changes brought by OLED E8 over the predecessor OLED E7 in term of input/outputs. As their major connectivity, both of them are equally equipped with 4 HDMI ports where all of their ports are already support CEC, HDCP 2.2 and HDMI 2.0 Full bandwidth. They also equally have 1 port that support ARC (Audio Return Channel) that is on HDMI 2. Additionally, there are no HDMI ports of them which support HDMI 2.1. Lacks of HDMI 2.1 may not have an impact for OLED E7, but for OLED E8 that already supports HFR (High Frame Rate Content), this makes it cannot play HFR content via HDMI ports due the bandwidth of HDMI 2.0 is not sufficient for HFR content. This means, it can play HDR content via USB ports only. Additionally, they are also equally equipped with 3 USB ports. But for this case, they have a bit difference where all USB ports of OLED E8 are USB 2.0 while on OLED E7, one port is USB 3.0 and the others are USB 2.0. In addition to USB and HDMI ports,  they are also equipped with the same other input/outputs like 1 Composite In (AV In), 1 Antenna In (Terrestrial), 1 Ethernet port, and 1 Digital Audio Out (Optical). Both of them are not equipped with Component In. As their wireless connectivity, they are equally equipped with built-in WI-Fi and Bluetooth.

LG OLED E8 and OLED E7 also have similar input lags in “PC” and “Game” mode. No matter the resolution of the inputs, their input lags are less than 25 ms that means it is great for any games.  The result, no matter you are playing 4K or 1080p games, casual or fast paced games, they allow you will play them comfortable and responsively. Combined to their excellent picture quality, great motion handling and good viewing angle coverage, this makes them as a great TV for playing games, even with a group of your friend or family where they usually watch from multiple angles. But keep in mind, since their image retention is not so good and they have permanent burn-in risk, play the same game over long time is not recommended.

Smart TV

WebOS 4.0 Review

Like we have mentioned above, basically, they are featuring the same smart TV platform that is WebOS. The difference, LG OLED E8 as an older model comes with older version that is 3.5 version while OLED E7 comes with 4.0 version. In term of user interface design, there are not many changes brought by the newer version over last version. There is only an additional quick access buttons on the top right of the home menu of 4.0 version for search functionally that makes them is different, but it is not too major.  Additionally, the preinstalled apps and features provided by them are also not far different. They equally have a lot of preinstalled apps like YouTube, Netflix, Amazon, Live TVs, Games, Screen mirroring apps, and many more, They also have an app store called “LG’ Apps Store” that provided thousands of downloadable apps, games, and others.  But even so, since LG E8 has been supported by Alpha 9 processor, and in sense, this has an impact on the performance of its smart TV where its smart TV performance is faster and more responsive then the predecessor. Meanwhile, like we have mentioned above, the major highlight offered by 4.0 version is about ThinQ AI where it now has been integrated with ThinQ AI. In addition to this allows you to control and monitor other ThinQ compatible device connected on your TV via your voice command, ThinQ AI also makes its voice navigation can do a lot of thing than the predecessor.

As their controller, they are also equipped with the same smart controller called LG Magic Remote. There are not many differences between 2017 and 2018 version, whether it is about their shape, button layout, smart features, and ability offered.  We have discussed a lot the ability of LG’s magic remote on other posts. One of the most useful feature offered by this remote is “point and click” that help to make navigation is far easier and faster. A bit difference between them is about their voice navigation ability where the 2018 model can do a lot of more job than the 2017 model. But keep in mind, this is more due by ThinQ AI than its own ability.

Conclusion

There are some major changes brought by LG E8 as the newer model over LG E7 the older model. The first is about their design like we have discussed above. But in my personal opinion, coming with new design doesn’t makes it looks more gorgeous but otherwise, this precisely makes its appearance is not as gorgeous as the predecessor. The other major highlight brought by OLED E8 is about Alpha 9 processor as its image engine where this makes OLED E8 can produce better picture quality and performance than the predecessor, particularly when playing HDR content. And the last, now all of LG’s TV line-up including OLED E8 have been integrated with ThinQ AI. Overall, OLED E8 has a bit better picture quality, HDR performance and also offer more attractive smart TV experience, but otherwise, lacks of built-in sound bar makes its appearance is not as gorgeous as  the predecessor LG OLED E7 and also makes its sound performance is also not as impressive as the predecessor.

Which is a better choice between them? As we have mentioned above, in the market, with the same screen size, OLED E8 is sold hundreds dollar more expensive than OLED E7, while the advantages and disadvantages between them have been discussed a lot above. Now, the decision comes back to you according to your own preferences and budget.
