Thanks for testing all and I am sorry about the problems... I assumed I could pick any resolution from the list returned by GraphicsModes(), and didn't realize the monitor could still have problems with that.
Perhaps picking the actual desktop resolution is the safe way to go then. (Except for possible video memory problems as mentioned elsewhere.)
But with this in mind, even setting up a list of resolutions for the user to choose from would be problematic? (As the list would include modes the monitor is not happy with.)
Or another option would be to hard-code a list of well-known resolutions and use only those resolutions from GraphicsModes() that also occur in the well-known list.
