Thanks, I'll have to try the "kocking" trick.
The problem is, I have two monitors set up right now, because the system came without the monitor cable. The original 1084 used the 6-pin barrel connector, which the 1084S doesn't seem to have.
Further, the 1084 is only mono, and I don't have a stereo-to-mono joining cable.
So, I have two monitors: the 1084 provides color video, and the 1084S provides black-and-white video with stereo sound.
Kinda wonky, I know...
