Pro Good value for money
While the B7A can seem rather expensive, the picture quality and features it offers is top-of-the-line and can’t be beaten. The performance easily outclasses all other TVs in this price bracket.

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.
Con Poor viewing angles
Those who view the TV at an angle will see a degraded picture because of the TV's bad overall viewing angles. For example, the image's black levels will start to shift once the viewing angle gets larger than 13 degrees.
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.
Con Below average sound quality
The sound quality of the B7A's built-in speakers is below average. It can't get very loud with the max volume peaking at ~85db, and sound quality it offers does not match the picture quality.
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.
