I've instaled the following Dell driver and BIOS updates from the Dell support page for this model: I'm wondering is perhaps the mysterious SMBus is supposed to leave something turned on (or turn something on) in the graphics port that tells the monitor that it's not really disconnected, but is supposed to go to standby. When I connect this Dell monitor to another computer (a Lenovo laptop of around the same vintage as the GX-620), at the "turn off monitor" time, the monitor blanks and the diagnostic doesn't appear. Two other monitors, when connected to this computer, switch to standby as expected, and return to operation as expected.

According to the monitor manual, this is what's supposed to happen when the monitor is disconnected, and indeed that diagnostic pops up when I unplug the video cable.

Now, the problem with the monitor is that when Windows power management turns off the monitor, rather than putting it in a standby mode, the monitor thinks it's disconnected and displays a diagnostic that remains on screen until the computer is awakened. A look at the SMBus suggests that it's a simple bus for controlling on/off things like putting the network controller to sleep when the computer is in a standby mode. A search in a driver database identifies it as such and points to an Intel driver for it. ID: VEN_8086&DEV_27DA&SUBSYS_01AD1028 (and more)ĭoing a Google search on the location and device gives mixed results, one of which said that there are over 1000 possibilities. I don't have a Dell Windows installation diskĪfter installing the Dell audio and Intel Graphics drivers, I managed to get rid of three of the four devices reported as "Unknown Device" in the Windows Device Manager. Operating System - Windows XP SP3 but a generic Microsoft version. I'm cobbling together a system and I'm left with one "Unknown Device" and one annoyance. Problem solved - too simple to fix but not obvious to troubleshoot. It's a "legacy" cable, so perhaps not all 15 pins are wired, and one was needed by this monitor that the others didn't that allowed it to recognize that it was supposed to be turned off and that it wasn't disconnected. Other monitors that I connected using this cable would go into standby when the computer shut off the video, but this Dell 1907FPt didn't.

Since the cable was fished through a desk, I was using the same cable as with the dead monitor that I replaced. This is all very interesting, and I did clear up an "Unknown Device" problem, but the problem with the monitor turned out to be with the VGA cable connecting it to the computer.
