Monitor sleep mode HOW?

    What triggers the sleep mode in a monitor which enables it to shut off
    and not show a "screen saver" mode which says no signal.?

    I have a problem in that my monitor will not shut down when the computer
    is turned off. There appears to be no signal coming from the computer -
    or so the monitor says on the nag screen - usually on other computer
    screens there seems to be a signal which the computer sends to the
    screen to signal it to standby mode. On an LG monitor the power light
    changes from green to amber and there is no nag screen.

    Have a Gigabyte 8IPE1000 Pro2 with a Radeon 9200SE 128m Video card. LG
    19" LG T910B monitor.

    I have used the card in another computer and that worked normally. The
    screen was substituted with another LG LCD display and that will not go
    to sleep either on this machine.

    So it points to the motherboard setting, software problem or BIOS.

    Is there a jumper or setting somewhere that can be used or is there a
    computability problem.

    any help appreciated.

    Right click on desktop, go to Properties then to Screen Saver tab. Now click
    on Power and under there is the option to Turn Off Monitor. If it is set to
    Never, it wont ever turn off while the computer is ON.

    However, none of that has anything to do with when your computer is shut
    down and the monitor still doesn't turn off. As you have said that you have
    substituted another monitor, then the problem is your video card. I recently
    built a computer with that motherboard and video card in it and don't have
    the problem you have. So, I suggest that either your video card drivers are
    not working properly or it is stuffed. Do yourself a favour and reinstall
    the drivers first. If that doesn't solve it, return it for another.

    Two things

    1. When there is no signal from the computer (As if the computer is turned off,
    or the computer turns off the signal, to save power ...)

    2. when the DPMS signal is sent from the video card.
    DPMS is a signal to tell the monitor to power save.
    there are two levels of powersaving in DPMS...

    So to get these to go,
    enable power saving in the monitor - especially
    'power off on no signal' or some such

    and enable power saving in your control panel/ display properties ...

    Most monitors are put into sleep mode by a command
    from the operating system, with the computer turned
    off this command does not get sent. This is because
    the default method, for many years, to power a monitor
    was having the feed through the computer power
    supply, thus when the computer was turned off the
    monitor was also turned off as it had no power.

    If your monitor is able to go into sleep mode whilst
    not connected to a computer it can be set on the
    monitor set up functions. If this capability is not
    setable on the monitor itself it can not be placed
    in sleep mode except via the software command
    from a running computer.

    Sleep mode is induced by stopping the output of the video card.
    When the computer is turned off, the monitor goes into sleep mode.

    That is NOT true of all monitors, many will just show a 'no signal'
    message, others will just sit there showing a blank screen as
    they have no input data to display. A few do have a built in action
    to enter a semi-powered sleep mode when there is no signal or
    when certain other criteria occur, but they are in the minority.

    The monitor LG when not connected to the computer will stay on with a no
    signal nag screen.

    When connected still stays on with the nag screen.

    I changed the Video card today with an old one and it now goes to sleep
    mode. So I'm inclined to think its something not working or compatible
    with the Radeon 9200SE card and LG monitors ( tried 3 different LG
    monitors 17" 19" and a LCD) all have the results. Yet an IBM and
    Mitsubshi LCD both go into sleep mode with the 9200 card.

    Tried a MAC monitor on the card and that could not trigger the screen
    into action at all. Yet this does work on other PC combinations.

    That's a bit different from a command from the OS?
