Dell 2408wfp rev. A02 Power Save Mode Problem

Jeremiah99,

What video card? What monitor ports have you tried? Is all Windows power management turned off?

I am using Nvidia GTX 275. I am using DVI-D 1 and all power management is turned off in windows.

Test the other DVI-D port on the monitor.

Same thing. I might add that it does this mainly at the start of windows. It goes into power save mode before i get into windows all the way then it comes back on then immediately goes back into power save mode a few times before stops. It has also happened while i was browsing the internet.

You did look at the label to verify it is an A02? If yes, I need the following sent to me in a Private Conversation -
Name:
Email Address:
Shipping address:
Phone number:
Monitor Order number or PC Service Tag number if purchased with a PC:
Monitor 20 digit PPID number found on the back on a label or on the slider card on the left rear:
Reason: 2408WFP A02 DVI Power Save failures

Is nvidia driver up to the date?

Yes

Do you have another spare video card? It is possible that the nvidia card could be problem?

Its not the video card. I have had a Samsung Monitor hooked up to this thing for a while and never had a problem. I just got the Dell 2408 and it started happening within a few hours.

Best I can think of is have Dell-Chris send you a exchange of another A02 and you put them both on dual and test.

After a bit of searching around the net, I've come to conclude that some monitors (not just the 2408WFP) is more susceptible to this. It's all based on the specific combination of LCD + video card + drivers. "CVT Reduced Blank" appears to be the setting that is most promising within video drivers (Forceware or Catalyst), but it's not the panacea that some had hoped for. Maybe Dell can work with Nvidia and AMD (aka ATI) to get this tested more thoroughly as it appears this problem also affects other LCD monitors, not just the 2408WFP.

Thus this isn't exactly just video card specific. There are 3 variables that are highly variable, which is what makes this issue hard to pin down to a specific solution.

I have exactly the same problem, except it has not happened right before getting into Windows. In the three times that it has happened, it was during browsing the web. Each time it happens it "blinks" and comes back within a second -- it has blinked only once each occurrence.

I'd be fine with this happening once every 6 months or a year, but once every week or month is just too much. What's going on with this monitor?

And before anyone thinks its my video card (EVGA GTX 260), I would tell you that its not simply because it hasn't happened with any other monitor. I've seen some others say that it's the DVI cable that's faulty. Also, I don't think hooking it up to DVI-2 is an option -- All ports should function properly.

I have an A02 revision that I received on May 29, 2009.

Also, not to thread-hijack, but does anyone know why everytime I post it "times out" and says there's an error with the forum, but when I look back at the thread, my post is successfully logged?

Specifically, it says:

A work order has been submitted.

Just to let you know, the blink basically happens once every time I have the computer on, typically during the first 10 minutes of browsing the net.
