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 Not good for group watching
Unfortunately, the curved panel of the Samsung Q8C looks good only from a single spot, which is located at the center of a circle made by the curve. If you need a TV that is suitable for group watching, this might not be the right option for you.
Con Narrow viewing angle
The maximum viewing angle of this TV is 14 degrees, making it useless for group watching, as those who view the TV from the sides will see degraded colors and shadows.
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 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 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.
