This is a widely spread problem with Dell flat panel monitors.

The problem is that the EDID (Extended Display Identification Data) on your monitor is corrupt. The problem only effects the DVI connection, so a temporary fix is to use the VGA connector instead. Dell has released a fix called DVI_recover.exe but it only will run on computers with an Nvidia card. Running this patch on a system with an ATI card leads to an DDC Channel access error. If anyone knows how to get this fix to run on a system with an ATI card - please let me know!

There is likely NO problem with your drivers, cable, power-supply, etc - so don't let anyone talk you into replacing/reinstalling. Until you fix the EDID corruption you will experience this problem with the DVI connection.

This is a Dell specific problem and Dell has not yet fully addressed it.

I was having the same problem as you.  I hadn't loaded the actual driver for the monitor yet, and I also went under properties, and switched the refresh rate to the "optimal setting" (60 hertz) rather than the 75 hertz.  Also, if you are using an LCD, be sure that you have the monitor settings to the recommended resolutation (1280x1024) on the 1905fp.

After installing the driver monitor (I got it off of Dell's site, rather than the CD that came with the monitor), and switching down to 60 hertz, the blinking immediately stopped.

Hope that helps,

You can get the DVI_Recover Utiltiy by asking a Dell Rep to give it to you, or you can just download it at http://www.jeffgeiger.com/stuff/dvi_recover.htm.
