Okay. More information. Sometimes, and I have no idea what defines those times, the screen, when normally in a brightness area that would show both sets of columns, will ghost, as if it's having bad OTA reception. It's hard to make out exactly what's going on, and I haven't caught it at a time when I can take a picture, but it appears that the always-on columns are being repeated in the sometimes-on columns to the left, opnly dimmer. I want to say that when this happens that the sometimes-on columns are also showing the correct thing in addition to the ghost.
