3008WFP, Power save issues
Hi, I really hope someone can help on this.
Precision T7500:
Quadro FX4800 DVI to DVI -DVI cable to 3007WFP DVI
Quadro FX4800 DP to DP cable to 3008WFP DP
The monitors are setup as dual view and both set to 2560 x 1600. If i drag a window across both screens it all works fine, if the screen saver kicks in they both come back when i tap the keyboard. The issue is that when the 3008WFP goes into its power save mode it does not come back up. I have have to go back into the control panel and extend the desktop to the screen and click apply. It then works fine until it goes to power save mode and i have to go through it all again. The same happens if you turn off the monitors and then turn them back on you are left with just the 3007WFP working and you then have to extend the desktop to the 3008WFP to make it work again. I have tried various drivers for the Quadro card (currently 182.67 and bios 62.00.25.01.02) and spoke with dell technical support who suggest a driver upgrade and to swap the cables round to set the 3007WFP as the Primary.
As always any help appreciated.
Thanks

Hi Chris,
The source is still selcted on Display port when it powers down. Whats happening is that as soon as it goes to power save it stops sending a signal to the graphics card. When the card stops receiving a signal windows XP changes its graphic setup to reflect the loss of the screen (basically goes back to a single screen mode)
To bring the moniter back you have to go into setup, extend the display to the new screen, change the resolution and positiopn of the screen and then its all fine until the power save mode happens again.
I must stress this is not the windows power save mode but a native power save mode on the monitors themselves.
Thanks, any help is apreciated.
Tom

"it stops sending a signal to the graphics card"
That is backward. The video card is the master that initiates the DP hand shake to the slave monitor. The monitor simply waits for the command from the video card. So the failure is in the video card driver or the video card.

Its the Nvidia Quadra 4800 (supplied in the Precision T7600 Workstations)

Yep, i spent an hour with a dell technician a while back. we updated drivers from dell. then tried Nvidia ones. We also tried using different ports on the card and it does the same thing.

And this issue occurs with both the Dell and the retail video card drivers?

Is there another PC you could check the 3008WFP on?

I have the same issue on 4 different units. I purchased 9 workstations (t7600)and 9 monitors at the same time. 5 seem to be ok as i have had no reported errors but the 4 other units all have the same issue.
I have tried to replicate settings and drivers from a working unit and i still get the same issues. If i plug the faulty monitors into a working PC i get the problem so i can only assume its the monitor and not the graphics card.
Any suggestions?

There is the chance that the 3008WFP firmware revisions are different.

When the 3008WFP doesn't wake up, what happens if you press the Input Source Selct button and re-choose DisplayPort?
