    I have my monitor display set to turn off after 15 minutes. Screen saver is
    set to engage after five minutes. Problem is, once the monitor turns off, it
    will not turn back on unless I reboot by pressing the power button on my
    computer. There is nothing else I can try because the monitors (dual) are
    both completely blank. The only way I can prevent this from occurring is by
    disengaging all screen savers and 'turn off display'. Then the screen saver
    never engages, and monitors never to blank, but I have to press the power
    buttons on the monitors to turn them off when I am not using the computer.

    I am running Windows Vista Ultimate 32bit, with all updates installed. I
    have 3GB memory. My video card is an ATI Radeon X1600 Series with 512MB
    memory. I just updated the drivers yesterday (11/11/07) to 8.421.0.0 dated
    9/28/07. My computer is a HP running at 3.6MHz. Other than the display
    issues, the computer runs just fine.

    What adjustments should I make so that I can use my screen saver and so that
    I can set my display to turn off after 15 minutes?

    Have you tried hitting the <Enter> key?
    Could be your HD is is miss set to turn off and you have to wait for it to
    spin back up before windows restarts, why don't you just hybernate?

    Anyone know how to resolve this? I have exact same problem as David but with
    slight difference. My primary monitor (left one) is connected to DVI
    connector and the secondary monitor (right one) is connected to VGA connector
    on the same video card (ATI Radeon 9200 - its an old card). If I turn off the
    monitors and turn them back on the primary monitor (DVI) is blank with "No
    Signal Input" message; the left one turns on fine. If I RDP into this machine
    from another one then the primary monitor comes to life. Another solution is
    to reboot the machine like David mentioned. I have latest ATI Catalyst
    software and drivers and have tried suggestions in other forums (like turning
    of Transient Multi Monitor task etc.) but nothing has helped so far. The same
    setup runs fine on WinXP. Any help is very much appreciated.

    it must be driver related issue
    however as you said you have installed the latest drivers
    turning off monitor by os is done by sending a message to the system &
    system turns on the display whenever it detects mouse or keyboard event
    try out a shareware at http://www.rtsoftwares.com
    don'nt think it will change situaton as the issue seems to be of a
    corrupted/incorrectly installed driver, but it might work

    Thanks for your reply Vikrant! While I am inclined to believe that it is an
    issue with the video drivers, uninstalling and reinstalling the drivers has
    not resulted in any improvement. I have tried TurnOffMonitor shareware
    utility from http://www.rtsoftwares.com and it seems to be working in a
    strange way ;-) When I turn off the monitors and turn them back on I see the
    same behavior as before even with the utility running in background. However,
    if I run the utility again it turns off the monitors (it always does when you
    run it) but moving the mouse or clicking the buttons brings both the monitors
    to life, YAY!!! While this is not ideal, it is certainly much better than
    nothing :) Thanks for suggesting the utility, much appreciated! Due to the
    problems I faced, I had disabled auto turn off of the monitor when the
    screensaver starts. I had also disabled the same in power management
    settings. May be I will use the utility to control these settings from now
    on. Thanks for suggesting this.

    yeah it should ask which monitor(s) to turn off

    It does not ask which monitor to turn off; it turns off both the monitors.
    May be I am missing something? Also, it would be great if it can detect which
    monitor is currently off and provide an option to turn on that monitor. May
    be I am asking for too much :)
