After spending an hour and a half on the phone with tech support yesterday I convinced them that the Official Weekend Pundit Main Computer's monitor was indeed malfunctioning, they decided that it needed to be replaced (under warranty, of course). I received confirmation via e-mail today that a 'new' monitor is on its way. (By new, they mean a reconditioned monitor. If I had to guess the 'new' monitor probably had the same problem and they've since upgraded the firmware for the microcontroller that runs the monitor.)
Since I'm too cheap..uh...frugal to spend any more money on something I already own, I declined their offer to ship it overnight or second day for a not-so-small fee. I'm willing to wait a few extra days for it to arrive.
