Consider the following scenario:
You have a computer that is running Windows Vista Service Pack 1 (SP1) or Windows Server 2008.
You let the system go idle for some time. Therefore, the monitor enters a low-power state, and the screen turns off.
To wake up the monitor, you press the computer's power button, or you use the remote control. The monitor resumes the full-power state, and the screen turns back on.
However, in this scenario, the monitor remains in the full-power state for only several seconds, and then it reverts to the low-power state.
Note This issue does not occur when you wake up the monitor by pressing a key on the keyboard or by clicking the mouse.
