Dell 2001FP monitors not coming out of power-save mode
I'm having an annoying problem with LCD monitors refusing to come out of power saving mode.
Let me start with the system details: It's a Dell Precision 390 with WinXP SP2; Quadro FX 550 with ForceWare 162.62 drivers; monitors are Dell 2001FP flat panels.
I have the system power options set to never power down the monitors.
Now, here's a way to solidly show the problem I have:
- Configure the card for single head operation, and connect to the monitor's DVI input. All works fine.
- Turn off the monitor power with the main switch
- Wait somewhere between 10 and 30 seconds
- Power the monitor back on
The monitor comes back in power-saving mode, and no amount of mousing or keyboarding will activate it.
There are two ways to get back from this state.
(1) Unplug the cable from the FX 550 card port 1; plug it into the (inactive) port 2; plug it back into port 1.
or
(2) Power off the monitor; remove the DVI cable; power on the monitor; replug the DVI cable.
I don't see the problems at all if I use a VGA cable to connect to the monitor.
In dual head mode the same effects can be seen, but here recovery option (1) is not available because there's no inactive port on the card.
Has anyone got any suggestions here? Do I have a faulty card?
Thanks in advance
Alan

This is a new system; it's the first time I've tried it with these monitors. The 2001FP monitors don't have an "autodetect" option that I can see - it's necessary to select between DVI, DSUB and composite inputs from the front panel.
Explicitly switching to DVI does not wake the monitors.
I have two identical 2001FPs and problem shows on both, on both heads of the FX550 card.
I don't seem able to get the fault to show on an LG monitor that I borrowed. SpooRancher

Sadly, there is no video-on-in-power-save setting on these monitors. The only option is for audio to stay on, and that's available only if a speaker bar is attached
Someone also suggested trying a factory reset; no improvement :-((
I hope today to be able to test this against some different monitors to see if it's a Dell monitor issue, a Dell 2001FP issue, or a fault in the two monitors I have...

The roblem is the dvi cable. I replaced the motherboard and video card on mine and still didnt work. using only the blue cord, into the standalone VGI outlet at top of back of computer and its fine.

I know this is an old thread, but I just came up with a workaround to solve the same problem I'm having with my triple-display with (2) Dell 2001FP monitors, (1) Dell 2408WFP monitor, and an ATI HD 6450 video card.
One of the Dell 2001FP monitors will not wake after Windows Vista tells the displays to turn off. The power light goes from amber to green, but the screen is dark. Turning power off/on to the monitor does not revive it. Rebooting the computer works. Also changing the display resolution or color depth will revive it, but it's a pain to change the resolution to something else, then change it back again.
So, I found a DOS utility to automate the process.
Step 1. Head over to this website and download and extract NirCmd
http://www.nirsoft.net/utils/nircmd.html
Step 2. Put the files into a common path, like C:\Windows. I have a directory for my DOS utilities called C:\Util and have added it to my PATH environment.
Step 3. Create a .BAT batch file in the same location as NirCmd with the following contents. I called my batch file refreshmonitor.bat
@echo off
nircmd setdisplay monitor:1 1600 900 32 60
nircmd setdisplay monitor:1 1600 1200 32 60
exit
You will probably need to replace the "monitor:1" with the monitor index that is affected. The index starts at 0. So the monitor #1 would be "monitor:0". In my case, it was monitor #2 that was giving me the problem.
The other parameters are horizontal resolution, vertical resolution, color-depth, and frequency. They are all required. I found it faster to change the resolution and change it back again, than switch the color depth.
What you're doing is changing the monitors resolution to something else, then change it back again. Changing the monitor's resolution revives the monitor.
Step 4. Add a shortcut to your desktop to your refreshmonitor.bat batch file.
So that's it! It works really well and the only trouble I have to go through is when the monitor is off because the power manager has turned off my displays after 20 mins, is to double-click the shortcut on my desktop. After a few seconds of flickering as the display resolution is changed then changed back again, my monitor is revived.
Hope this helps.
Note: If someone knows how to run a task in Task Scheduler for when the displays are turned on (not computer awake, that's different), that would automate the whole process. There is an Event log System/Power-Troubleshooter event ID=1 which you could use to trigger running the batch file, but that is for when the computer wakes up. I'm looking for an event when the display wakes up.
