I have a Samsung 213t LCD. I used to just leave the computer on all the time with no screen saver. Recently I have been trying some power saving features and have the monitor set to turn off after 30 minutes and the computer set to hibernate after a few hours. When I return to the computer and it is still on but the monitor is off it is very hard to wake it up. I have to wave the mouse around, click both buttons, and hit the windows key several times.

I am using a wireless mouse and keyboard so maybe that's the problem. The other weird thing is when windows shuts off the monitor it just kills the video so the monitor check all the inputs the shuts itself off.

I can turn it on with the power button on the monitor but then it checks the inputs for a while before coming on so it takes about 30 seconds which seems longer than it really is

Any ideas ?
