I've had my 55B7A for a couple of weeks after switching from years with an ST30 series Panasonic plasma. Overall, the OLED TV is stunning and viewing content on the bezel free display is much like being at the theater. Using a combination of the AVS and Rtngs picture settings, the colors are natural, blacks are deep and judder nearly non-existent for the most part. I stream all content using a Roku 3 along with control via the Harmony 650.
However, in VERY rare occasions there's a slight imperfection. If watching a movie where the room is dark and a flashlight or torch is used by a character, a split second blue artifact/line pops up to either side of the bright light, though as I say its rare. I called support who had me do a power reset to remove static, but nothing changed. It's not a deal breaker by any means; the device is FAR superior to the plasma so I'm happy to live with it. I'm curious if anyone else has noticed this and if so, whether there's a remedy. Thanks.
