1970fp dvi Monitor won't fully sleep

Since I bought a new PC, the video card has a DVI connector so I thought why not use the cable that came with this monitor and connector it to via DVI.

Everything is good with the driver, no yellow explanation mark or any other errors. The monitor is correctly identified and there are no new updates for it. It is the "best driver" installed.

After visiting Dell's website, I seen this driver isn't listed in the Windows 7 64bit area, in fact, it's not listed in anything but Windows XP and older.

The problem is the Dell monitor will somewhat fall alseep but not fully. The monitor turns off but not completely, it goes into self test mode and moving the mouse or pressing a key awakes the monitor.

I never had this issue with XP and in fact, I don't have this issue when I connect my monitor to the VGA connector while running in Windows XP. I still use my XP machine often.

Is this a common or normal problem? Should I try running Windows XP Virtual PC to see if I have this problem there?

Thanks everyone.

I wasn't aware of the compatibilty feature also applied to the driver. Win 7 installed the driver on it's own. Adrian, I had previous played with the Advance settings and that didnt change things.

In any event, looks like the sleep issue is resolved.

It appears it may have been a hardware/software issue. This is what I did: I disconnected my DVI cable from monitor and connected the VGA to it that was also connected to my XP machine. When I started the XP PC, the monitor recalibrated itself (Auto Adjust) during the initial boot process up (BIOS screen). That was odd. I then checked my XP display settings when the boot process was completed and everything was normal.

I shut down XP, disconnected my VGA cable and plugged in my DVI cable and started Windows 7. I had the sleep mode set to 1 minute for testing purposes and it went to sleep without a hitch. The monitor didn't need to "Auto Adjust" at all. Go figure?
