2408WFP Power save mode problem

Hi, i have a system with the dell 2408wfp on DVI and ati 9600pro graphics card on windows xp pro.

 

1) once windows is idle and sends the monitor into power save mode, moving the mouse or pressing on the keyboard will not wake the monitor up. only a reboot will fix it. this does not happen when using the vga connector or on the dvi->vga converter.

 

2) not only that, i have to have the dell powered up before powering up my computer. if i power up the computer 1st and later power on the 2408wfp, there will be no signal to the monitor as well and get stuck in power save mode.

 

3) lastly, when i tried to isolate the problem further by setting the windows "turn off monitor" setting to never to ensure that the monitor will never power off. then i switched inputs to another input, then immediately switching back to the DVI being used results in the same power save mode issue.

 

i have tried updating my graphics drivers to the latest ones already. the power save issue is resolved for one instance after the reboot, but comes back after i switch inputs.

 

what could be the problem here? thanks

Re: 2408WFP Power save mode problem

thanks for the reply.

unfortunately i only own this pc with dvi port.

 

neither do i have another video card with dvi port as well.

 

does this sound like the other power save mode problems that others have experienced?

i have called dell technical support in my country. they are sending me a replacement monitor to test. i should be able to isolate the problem more from there.

 

i will post back when i get it.

CrymsonArray,

Sounds like the video card firmware is defaulting to VGA on wake up.

CrymsonArray,

Flashing the video card firmware (which would have to come the manufacturer, not Dell), or a newer video card.

ok.

 

how abt situation #3 in my original post? is that related to defaulting to vga?

 

and i have also tried powering off the monitor when it is not on power save mode and powering it back on again in windows. it doesnt work. still goes back to power save even though the previous mode before powering off was fully on (green led).

 

so the problem is inherent of older ati video cards (9k series, x600 series?)

CrymsonArray,

Not sure about #3. So far, it is effecting all of the older cards we have on hand.

i see. so i shall test it out further when i can get the replacement monitor. seems very weird that even if the video card is sending proper signals to the monitor the monitor does not get it for the situation #3.

Re: 2408WFP Power save mode problem

I have a brand new 2408wfp bought from DELL UK and delivered on 20 March 2008. It has the powersave problem detailled here and elsewhere on the internet - once it is in Powersave I have to reboot the PC via the power switch.

 

The reason for posting is that I have an ATI 9800 pro video card using the DVI input  and was using catalyst 8-1.

 

Last night I upgraded to the latest Catalyst 8-3 issued on March 5th 2008.

 This has solved my problem and I can now get back from Powersave by any keyboard or mouse activity. I suggest others with a similar problem who are using ATI video cards should do the same rather than getting a new monitor.

 

Tom.
