Pros
Pro Excellent for watching sports
The B7A is an excellent choice for sports fans because of its virtually non-existent motion blur, and it has the ability to reproduce realistic and good looking sports fields.
It has near-perfect pixel response time of ~1.0ms, resulting in virtually no motion blur, so fast-moving objects like football don’t leave any trails on the screen.
The panel is also uniform enough that it has no issues with displaying large, same-color objects on screen, like football fields.
Pro Exceptional picture quality
The B7A's picture quality is top-of-the-line. It has an OLED panel that gives it infinite contrast ratio, excellent screen uniformity, high peak brightness, wide viewing angle, and great handling of reflections.
Thanks to that, it can reproduce blacks perfectly and the uniformity is top-notch - they’re truly dark and even, because the OLED panel has the ability to manipulate pixels individually.
Colors really shine and look true-to-life, thanks to the peak brightness levels peak of ~400 nits for SDR & ~700 nits for HDR.
The picture quality also doesn't suffer from much deterioration when viewed from any angle because the panel has a really wide viewing angle. It’s also capable of maintaining the same picture quality in bright environments, thanks to its high peak brightness levels and great handling of reflections.
Pro Extremely versatile
The B7A is great for movies, gaming, and sports. Its top-notch picture quality, combined with the features it offers, makes it perform really well across different kinds of use cases.
Movies look immersive thanks to the exceptional picture quality. It’s really responsive for gaming - players will have no issues keeping their actions in sync with what’s on the display, and fast-moving objects won’t leave any trails on the screen. That is thanks to the really low input lag of ~20ms and near-perfect pixel response time of ~1.0ms, resulting in virtually no motion blur.
It’s also great for watching sports because of the non-existent motion blur, and the panel is really uniform - it has also has no issues with displaying large, same-color objects on screen, like football fields.
Pro Remote is well-designed
The B7A comes with LG's Magic Remote, touted for its easy-to-use design.
It works similarly to a Nintendo Wii remote where the on-screen cursor follows the remote's movement, making it easy to navigate the UI and select menu items.
The remote also has a built-in microphone for the voice command feature, which also supports content searching with voice input.
Pro Interface is intuitive and user-friendly
The B7A runs on the webOS smart platform, known for its intuitive and fully customizable UI. It’s built around a Launch Bar that provides quick and easy access to the TV's apps, settings, and inputs. This can be customized and re-organized to the user's liking.
Pro Smart platform has great ecosystem of apps
The B7A runs on the webOS smart platform. It has a great ecosystem of apps, ranging from media streaming services (Netflix, Amazon, YouTube, etc.) to third-party apps. Support for these apps are also first-class with up-to-date features and good performance; for instance, the YouTube app supports 360-degree video playback.
Pro Wide viewing angle
The B7A looks good from almost any angle thanks to its OLED panel, making it a great choice if you usually watch the TV with large groups of people.
Its viewing angle is wide enough for a group of audience to experience more or less similar picture quality when watching from multiple angles off the center of the screen. The black levels and brightness only starts degrading at ≥75°, which means the picture quality will stay roughly the same no matter which angle the screen is viewed from.
Cons
Con Suffers from image retention issues
The main drawback of OLED panels are image retention issues with static images - pixels on the panel gets burned in when the picture doesn't change for extended periods of time. This usually happens with content that has a static image anywhere on the screen, like the logo of TV channels.
As the B7A has an OLED panel, it unfortunately suffers from this problem. There might be some retainment of artifacts for ~15 minutes when this happens, and it usually goes away after watching other content without static images.
There are some cases where normal content won't cut it, which usually happens when the static image has been there for more than some hours. Fortunately, the B7A has a “Pixel Refresher” feature that can recalibrate the screen, which should get rid of any remaining artifacts.
Con Interface has ads
The B7A's interface includes ads that can’t be removed - there’s no option to disable it. Ads on this TV can be really annoying when compared to other smart TVs because they're almost everywhere. There are video ads in LG's Content Store, apps menu, and even voice search results.
Con May require some color calibration out of the box
Out of the box, the B7A’s white balance might look slightly off to some viewer, so a brief calibration might be required if you notice it. Fortunately, all the optimal color settings are available on the internet and isn’t hard to find.

Flagged Pros + Cons
Con Doesn’t sound good
The TV’s sound quality is not on par with its brilliant picture quality. Adding a decent soundbar will make a massive difference.
Pro Good for HDR media
The TV supports both flagship HDR formats: HDR10 and Dolby Vision, which means that you will have a lot of HDR-enhanced media to choose from. The TV does a fantastic job of displaying such content because of its infinite contrast ratio, high HDR peak brightness, and wide color gamut.
Con Suffers from image retention issues
The main drawback of OLED panels are image retention issues with static images — pixels on the panel gets burned in when the picture doesn't change for extended periods of time. Noteworthily, the static image doesn't have to be whole like a full wallpaper on the TV; it can happen with content that has a static image anywhere on the screen (e.g. the logo of some TV channels).
As the LG B7A has an OLED panel, it unfortunately suffers from this problem. There might be some retainment of artifacts for ~15 minutes when this happens, and it usually goes away after watching other content without static images. There are some cases where normal content won't cut it, which usually happens when the static image has been there for more than some hours.
This can be remedied with the LG B7A's “Pixel Refresher” feature — it recalibrates the screen, which should get rid of any remaining artifacts. Note that this procedure takes around an hour, and the TV has to be turned off the entire time for it to work properly.
Pro Great color reproduction
The B7A can reproduce a really broad range of colors that are crucial for HDR, which also means it has zero issues with SDR colors.
It’s capable of reproducing ~70% of the standard colors for 4K HDR, the Rec. 2020 colorspace. This is one of the highest in the 4K TVs market.
It can also display these colors at different brightness levels accurately that conveys much more HDR details than its direct competitors can.
Pro Perfect for HDR content
The B7A is the perfect choice for HDR content. On top of its exceptional picture quality with perfectly deep blacks, it has everything essential to an excellent HDR experience: an OLED panel, wide color gamut, and high peak HDR brightness levels.
Shadow details are perfect and highlights are really stunning, making for an immersive experience. The OLED panel can manipulate pixels individually, which means it has control over every tiny bit of the picture.
The panel can also reproduce the colors necessary for true HDR, and these colors will really pop thanks to its high peak brightness level of ~700 nits.
Pro Suitable as a computer monitor
Because of its full 4:4:4 color support, the TV can display clear and crisp image while connected to a computer.
Pro Well-designed remote
This TV comes with LG’s excellent Magic Remote which can make the on-screen cursor follow its movements, much like a Wii U’s remote. Additionally, the remote can be used to send voice commands to the TV.
Pro Excellent for HDR gaming
This 4K120 TV is an excellent companion to any current generation gaming console. With this TV, you can even enjoy the smooth, immersive effect of HDR gaming since the LG OLED 7 series does not suffer from increased input lag despite processing high bandwidth signals. In fact, this TV outperforms all of its main competitors, such as the Samsung Q7F, when it comes to HDR gaming.
Pro Excellent for gaming
The LG OLED 7 series TVs are simply great for gaming because they can provide responsive and lag-free gaming experience as the TVs feature low input lag and excellent pixel response time.
The pixel response time of this TV is only 0.2 ms, which ensures that you will never have to deal with the unwanted effect of motion blur, as it is virtually eliminated since the pixels need only around 1/5000th of a second to change their color.
Additionally, while in gaming mode, the TVs input lag drops to unnoticeable 21.1 milliseconds, so it is very likely that you will not even feel the delay between you pressing a button and a reaction appearing on the screen.
In both cases, the LG OLED 7 series TVs outperform their closest competitors, including the Samsung Q7F.
Con Requires color calibration
Out of the box, the TV’s color accuracy is not that great. Expect to spend some time calibrating the panel.
