Asus going into monitor powersave mode, can't get out - help!

[BobMarley]

3 times recently, my monitor has been left on for about 8 hours while
I'm at work... when I come home, the monitor says it is in powersave
mode, and to start it back up from the PC...

well, the PC won't turn the monitor back on. I can RDP into the pc
(it's windows XP sp2), and can see everything, so the pc is definitely
"on"... but no matter what key I hit or mouse button I click, the
monitor won't come back on.

A hard reboot turns the monitor on, for the XP splash screen, but
before it gets to the logon screen, it goes back into powersave mode.

So I know everything works...

So to get back, I boot into safe mode, remove the Nvidia drivers, and
reinstall.. and it's fine.

It's a workaround but a pain in the ass.
Anyone have any ideas? My powerschemes are disabled, the monitor is
set to never shut off within XP.

It seems that the times this has happened, that the monitor cable has
been removed from the desktop (I do this to keep people from using the
pc). And when I come back and reattach the cable, it can't turn the
monitor back on.. ever again, without a reinstall.

any ideas?

I cannot solve your problem, but I can explain why it is happening.
Video cards were given "jack sensing" a few years ago. This means
the video card can sense that the R,G,B lines are terminated with
the termination resistors in the monitor. Similarly, if you
have a TV output connector on the video card, the video card can
sense whether a TV is connected. What is likely happening, is the
video card is automatically switching the output from the VGA
connector, to one of the other connectors on the video card.
That is why, when you RDP, everything looks normal, because
the frame buffer is now driving the TV connector, rather than the
VGA. (When you RDP, check and see if the Display properties
have changed to less than 1024x768, as that is the max for
output to a TV.)

On one computer I have here, I got a VGA connector from an
electronics store (just the bare connector and plastic connector
shell). I got three resistors and soldered them between R,G,B
and GND. With this "stub" connector, when I connect it to the
video card, the video card sees 75 ohms between each video
line and ground, and it will continue to think there is a
monitor connected. I used this on one computer with the
same stubborn habit yours has got, and when I unplug the
monitor, I plug the "stub" connector in, to keep the
computer thinking it has a monitor. Otherwise, when I
come back later, output is on the TV connector, and
it is a royal pain trying to navigate a Display
properties pane using a TV set

Now, the real question is, why doesn't the video card
driver switch back in all cases, to the VGA, when the
VGA is plugged back in. That is what I'd like to know.

I have the same trouble now that I am using a flat panel display and dvi
connector. I found that if I unplug the monitor, it will then see the video
signal. Simply turning the monitor's power off and back on isn't enough.
I've got a surge protection power strip under the monitor, so I can "unplug"
is easily. If this works for you, it would easier than rebooting in safe
mode.

Why don't you just password protect a 'screensaver' and leave the thing on and
go into powersaveing mode.....that way the monitor is still hooked up..and goes
into powermode..and if your so worried about someone using you comp.....take the
keyboard with you...sheeeeesh...the screesaver will be password protected.
