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 Doesn’t look good from an angle
The picture quality of this TV is terrible when the angle between the viewer and the panel is greater than 10 degrees because at this point the viewer will experience noticeable black level degradation. Once the viewing angle reaches 21 degrees, all the other colors will start to degrade. This property makes the Samsung MU6300 not suitable for watching with a crowd.
Con Has ads in the main interface
The main interface of the Samsung MU6300 has some advertisements and suggested content.
Con Can’t handle judder
The Samsung MU6300 cannot fight judder in 24p sources. As a result, some users might experience so-called ‘2:3 judder’ while watching 24p content from old Blu-rays and DVDs.
