Ive kind of damaged a Microvitec multiscan monitor on my A1200 by accidentally selected the A2024 resolution form Workbench. The screen went black and blue for a few seconds, and the monitor made noises like popping popcorn before I reset the A1200. The monitor still works, but now has a yellowish tint, which can be resolved by a bang to the side of the monitor (not very technical I know! :-o ). The problem becomes less as the monitor warms up.
