My Star Wars has this exact same behavior. I've even tried swapping monitors,
but it still remains. My line is white, however.

Mine does not do this.

More Star Wars...

I have a monitor with the LV2000 installed, and just as the Death Star
explosion finishes and everything is returning to normal, the vectors are all
"connected" for a brief moment to the center of the screen, then everything
returns to normal. I suspect this has something to do with the HV being taxed
during the explosion, and the swing back causes this brief syptom? Could
someone explain to me technically why the monitor "blooms" during the Death
Star explosion?
