Pros
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 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 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 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 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.
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 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
Apart from movies, the B7A is great for 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.
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.
Cons
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 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 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
Pro Excellent for dark rooms
This TV performs exceptionally well in dark environments. Its ability to produce absolute and perfect blacks means the reproduction of dark highlights and scenes in movies will look great — this is further improved when there's no light around the TV as it allows the blacks to stand out more. This makes it great for watching all sorts of movies in a cinema-like setting, particularly movies with many black highlights/scenes where this is immediately noticeable even to undiscerning viewers (e.g. Interstellar).
Pro Great performance for sports & gaming
The B7A's versatility is top-notch. The motion blur at ~1.0ms makes it an excellent choice for sports & gaming, and the low input lag of ~23ms contributes to this especially for gaming where input lag matters.
Pro Excellent gaming TV
The LG OLED 7 series TVs are ideal for gaming because of their low input lag and near-perfect motion blur handling which is combined with the excellent picture quality of the TV.
This TV has almost negligible motion blur because of its panel's pixel response time of 1.0 ms, which ensures that it takes only 1/1000th of a second for the TV's pixels to change their color.As a result, rapidly-moving objects look smooth and won’t leave traces on the screen.
The input lag of this TV is only 21.6 ms, which means it takes the TV just 1/50th of a second to process a button input while gaming.
