Thanks for you fast reply. I think this is the problem because the monitor gives a sound when going to screen saver mode and it does the same when switching to a higher mode in X11. He repeatedly beeps on, I think because the sync says "power down" and there is a video signal so it tries to display. Thank you also for your offer, so if you have some time to look for the sync description this would help. The Philips manual lists the sync modes, but they may be false ...
