Makvision monitor I just got (Is it multi-sync?)
grantspain:
these monitors are not designed to switch resolutions during power on mode,it will eventually kill the horizontal deflection transistor
no monitor ever built has ever been designed to cope with what many mame builders attempt to do-apart from lcd of course
people need to understand that these monitors are built for industry and not home users.In the industry we do not have any machines that switch resolutions constantly.
i would say a good amount of monitor faults on this forum are caused by frequency switching
amendonz:
How about just turning them off and on? Like swapping PCBs and stuff, does that do any harm if you do it too often?

you can power down and change as many boards/resolutions outputs as you like and cause no damage-the problem only occurs when resolution is changed during power on mode
i did a ton of work on tri sync chassis some years ago,testing them on various tubes and resolutions but they were all done in an industry arcade scenario

But the power cycling on a MAME machine would be so frequent, that wouldn't it be rough on components, also?
