Technologies and Features of LG OLED B7 and OLED E7

Ignoring their differences, LG OLED E7 and OLED B7 are powered by similar technology and most features which offered are also almost the same. Coming with OLED panel that offer infinitive native contrast ratio and perfect black level, they are powered by the number of LG’s most advanced technologies which maximizes their picture quality. On their color reproduction, both of them use 4 sub-pixels technology where there is white sub-pixel as the additional of the standard sub-pixel (RGB).  There is also True Color Accuracy that maximizes the accuracy of color produced. Additionally, for improving their peak luminance, there is Ultra Luminance, makes the picture displayed looks bright and consistent amazing when set in a bright room. Meanwhile, coming with HDR technology, LG OLED B7 and OLED E7 are powered by Active HDR engine and already support most of HDR formats which available like HDR 10 by UHD Alliance, HLG by NHK and BBC, Dolby Vision by Dolby Laboratories, and Advanced HDR by Technicolor. Not even just that, to indulge you in enjoying HDR experience in your home, both of them also has a feature named “HDR effect” that is able to improve the brightness and color range of the picture as close as possible to 4K HDR, allow you to enjoy any content in nearly 4K HDR quality. They also already support Dolby Atmos, allow you to enjoy HDR entertainment with Dolby Atmos Sound experience. Additionally, to ensure their HDR performance is great, both of them are certifies by Ultra HD Premium Certification that means they are able to show HDR images fully like the intended, especially for HDR 10 images. The other advantage that offered, the picture displayed on their screen looks excellent not only when viewed from center and front. But since it has extremely wide viewing angle coverage, the picture displayed on their screen also looks excellent when viewed from any angle.

HDR Effect

Additionally, since it uses OLED Panel that has excellent pixel response time, this makes both of them can handling motion blur excellently when playing fast moving images. When playing 24p movies, performance of both is also excellent by delivering smooth and clear picture quality with judder-free.  For connecting with other devices, they are also equipped with 4 HDMI ports, 3 USB ports, and other inputs outputs, allow you to connect most of your other electronic devices at once. Additionally, although not low as SJ8500 or SJ9500 series, their input lags in “Game Mode” is also quite low to play any games so feel responsive without laggy. And to complement your comfort in enjoying 4K HDR entertainment in your home with attractive, responsive, and simple smart TV experience, both of them feature WebOS 3.5 as their smart TV platform.

The differences between LG OLED B7 and OLED E7

Design

The major difference between LG OLED E7 and OLED B7 is about their design. OLED TV comes with “picture on glass” design that makes it is different to most of TVs which available in the market. This is also one of the factors that makes it is priced far more expensive than OLED B7. The main panel is mounted on a thin of glass without any metal or other materials which support it, makes the TV looks very thin on about two thirds of the top if viewed from the side. Additionally, when viewed from the front, the border also looks very thin with outer edge is glass and inner edge is black. Meanwhile, about third of bottom, when viewed from the side, the TV looks thicker where in this part, all of the hardware and connectivity of OLED E7 are installed. Along the bottom of the panel, there is built-in sound-bar with a radiator-style grill and along with a footprint at the center of bottom, they support the TV sturdy and stably. Meanwhile, although not coming with “Picture on Glass” design, LG OLED B7 also has excellent design and looks impressive in your room.

Built-in Sound Bar

The other main difference between them is about built-in sound bar. LG OLED E7 is equipped with built in 4.2 channel sound bar with 40 watts of total sound output and installed at the bottom of the main panel. With a radiator-style grill design, it makes the TV looks more impressive in your room. Additionally, since OLED E7 already support Dolby Atmos, its built-in sound bar also allows you to enjoy Dolby Atmos experience without adding external sound bar. On other hand, LG OLED B7 comes with standard audio system that is 2.0 channel speaker systems with 20 watts of total sound output. Since there is a firmware update for OLED B7 that already support Dolby Atmos, due it doesn’t have built-in woofer, to enjoy Dolby Atmos experience with OLED B7, you need an additional external sound bar.

Remote Control

LG OLED E7 vs OLED B7 Remote

 

Although both of them equally come with LG’s Magic Remote as their controller, but the type of their remote is different. Essentially, both of these remote have almost the same button configuration, smart features, and functionalities, but their design is different. The body of the remote of OLED E7 is much longer but thinner and made by higher quality material. Meanwhile, the remote of OLED B7 is shorter but thicker and the material is plastic.

LG OLED E7 vs OLED B7 Performance

Picture Quality

Overall, both LG OLED E7 and OLED B7 have excellent picture quality. The one of the strongest factor that makes their picture looks excellent is their infinite contrast ratio and perfect black level. Since both of them use OLED technology that has self-lighting pixel, that means each of pixel can switch on/off/dim individually without affected by the condition of other pixel surrounded. When displaying totally black color, this allows the screen doesn’t emit light at all. The result, black looks perfectly on their screen. Indirectly, this also makes darker colors can be shown fairly accurate. And combined to its perfect black uniformity and strong performance of other factor of picture quality, this makes dark scenes of image displayed on their screen looks excellent. This certainly makes both of them as the perfect TVs when used to watch movies in a dark room. Additionally, their perfect black level doesn’t only make dark scene of SDR images looks excellently. Moreover, their black level is also quite dark to reveal details images in dark scene of HDR images, makes shadow details of HDR images looks excellently like the intended.

OLED vs LED TV Contrast

On the other hand, although not as bright as premium LED TV like Sony X930E or Samsung Q9F, both LG OLED B7 and OLED E7 also have great peak luminance. The result, since their peak luminance is quite bright to dampen the glare and combined to their excellent reflection handling, this certainly makes both of them are able to maintain their excellent picture quality, even in a room with sunny window or extremely bright light.  Additionally, when inputted by HDR signal, both of them even can produce far brighter peak brightness, brighter than 550 nits as the minimum standardization set by UHD alliance. The result, both of them are able to show highlight of HDR images fairly bright like what recommended by UHD alliance as the developer of HDR 10 format. But unfortunately, their peak brightness is still lower than 1000 nits that means they cannot show highlight of HDR images brighter than 1000 nits or as bright as the brightness range where HDR images are usually mastered. As we know, images are usually mastered in 1000 nits – 4000 nits of brightness range. This certainly makes its performance when showing highlight of HDR images is not as good as the premium LED TVs like Sony X930E or Samsung Q9F that has peak brightness brighter than 1000 nits. Nevertheless, for OLED TVs, peak brightness produced by LG OLED E7 and OLED B7 is great, and at least, this meet the minimum standardization set by UHD alliance to get Ultra HD Premium Certification.

10 bit vs 8 Bit Depth of color

Meanwhile, although not the best, both of LG OLED B7 and OLED E7 also has excellent wide color gamut and their color gamut is only a bit narrower than Samsung QLED TV lineup as the TV with widest color gamut. Almost all colors in DCI P3 color space are can be shown fairly accurate and in Rec.2020 color space, only green that cannot be shown as saturated as other colors. But even so, this is not their own problem since most of modern TVs also have the same issue when showing saturated green. The result, color of SDR or HDR images displayed on their screen looks fairly accurate, makes the picture looks natural. Additionally, the excepting of at their high brightness, both of LG OLED E7 and OLED B7 have good color volume. This means, except at nearly their peak brightness where their wide color gamut narrows significantly, they can fairly well show their wide color gamut at almost their entire brightness range, even at extremely dark colors. This is the opposite of most LED TVs, where their color gamut usually narrow at darker colors but at their nearly peak brightness, they can show wide color gamut fairly well. Still about color performance, both of them also are also able to show 10 depth bit of color fairly well. The result, when displaying HDR contents that usually mastered in 10 depth colors, color gradient of the picture displayed on their screen looks very smooth with almost no color banding. Like most TVs which available in the market, some little imperfections might still be visible in grayscale and dark colors, but overall, this should not be a serious problem when you are watching movies.

The other advantage that offered by LG OLED E7 and OLED B7 is about their ability to maintain their amazing picture quality when viewed from an angle. This means, no matter the angles you are watching from, the picture displayed on their screen will look as good as when viewed from the center and front. What offered by OLED B7 and OLED E7 even is better than IPS TV that indeed is designed to maximize the side viewing angle coverage. With great side viewing angle coverage, of course this makes both of them as a great TV for you if you often watch TV from a side angle.

Overall, both of them have similar picture quality and great HDR performance. No matter the light condition of a room where they are used and the angle you are watching from, the picture displayed on their screen will look remain amazing. The only drawback of them is about their bad image retention (burn in). Nevertheless, their image retention is not permanent and can be got rid with a feature named “Pixel Refresher” under “OLED Panel Setting” on their “Picture Setting” menu.

Motion Handling and 24p Playback

LG OLED TV Motion Blur

The other perfect performance that offered by LG OLED B7 and OLED E7 is about its ability in handling motion blur. As we know, OLED panel has individual self-lighting pixel, this allows each of pixel of OLED panel is able to render change the color extremely fast, far faster than any LED TV. This has something to do when displaying fast paced contents where the slow pixel response time will cause a visible trail following fast moving object. And the faster response time of the pixel, a trail following fast moving object will look more faint. Since OLED panel has extremely low pixel response time, this certainly makes a trail following fast moving object when they are displaying fast paced contents is almost no visible. The result, the picture displayed on their screen looks very smooth and clear when they are used for watching fast movies or sports. Additionally, when used for playing 24p movies, both of LG OLED B7 and OLED E7 also offers great performance. No matter frame rate of the source, whether it is 24p videos like Blu Ray Movies, 24p videos via 60i signal like movies from TV Satellite, or even 24p videos via 60p signal from streaming device, all of them will be displayed clearly and smoothly with judder-free. To remove the judder without adding “soap opera effect”, you just need turn on the “Real Cinema” option, set “TruMotion” to “User” and set both of “De-judder” and “De-blur” to “0” on their picture setting menu. And since both of them have native 120 Hz refresh rate panel, this certainly makes them are able to interpolate both lower frame rate contents 30 fps and 60 fps.

Inputs/Outputs

As their connectivity, both of LG OLED E7 and OLED B7 are also equipped with similar inputs/outputs. There are 4 HDMI ports as their major connectivity which already supports HDMI 2.0 full bandwidth, HDCP 2.2, CEC, and more. Meanwhile, that support ARC (Audio Return Channel) is HDMI 2. In addition to HDMI ports, there are also 3 USB ports, 2 USB ports ver.2.0 (USB 2 and USB 3) and 1 USB port ver.3.0 (USB 3).  In addition to HDM and USB ports, both of them are also equipped with 1 Antenna In (RF), 1 Composite In (AV In), 1 Ethernet port, and 1 Digital Audio Out (Optical). There is no Component IN behind them. Meanwhile, their inputs lags in “PC Mode” and “Game Mode” are also excellent. Their input lags might not as low as SJ8500 or SJ9500, but they are quite low to play any games so feels responsively without laggy, even for fast paced games that require fast reflexes. Combination of excellent picture quality, good motion handling, and low input lags, thus certainly makes them are a great TV when used for playing games.

Smart TV

LG WebOS 3.5 Review

As their platform, both of them also feature the same smart TV platform that is WebOS 3.5. As we know, WEBOS is one of the best smart TV platforms that offer simple, attractive, and responsive smart TV experience. In this version, WebOS 3.5 is powered by a new chip that make its performance is faster and more responsive while navigation is still simple. On its home menu, there are strip bars across the bottom of the screen contain quick access to most popular apps, setting, and inputs selection. This makes navigation is faster, allow you to launch them without leaving the “Home Screen”. Meanwhile, apps provided are also very complete and varied. There are VoD Service like YouTube, Netflix, Amazon, and more, Live TV, Web Browser, Games, and many more. Meanwhile, although not many as Samsung apps Store or Google Play Store, WebOS also has apps store named “LG Apps Store” that provided tons of interesting and useful apps, games, and content where you can directly download from your TV.

As their controller, like we have discussed above on their difference section, although both of them are equipped with different type of remote, but basically they have similar smart features and functions.  That is interesting, there is dedicated buttons for Amazon and Netflix, allow you to launch them without entering the main menu. Their remote also have voice command functions, and although not as excellent as Samsung remote, their voice command is enough to help simplify the navigation. Additionally, their remote also has universal capability that means they can be used for controlling other device connected on your LG TV. And the excellent feature that offered is about “Point and Click” feature. With scroll wheel on the center of the remote, this allows you to navigate like using a mouse on Notebook. Not even just that, the pointer on the screen can follow the remote’s movement, allow you to select the menu or icon directly.
