I'm putting together a system for a kiosk which will have two displays, a hardened Happ, and an ELO touchscreen. I had both of these plugged in and working at one point, but had pulled the ELO back to use on a development system. Now when I fire up the DH61DL, I can not get dual display working at all. With the two screens mentioned, it just does not recognize the second screen plugged in to the DVI (via a DVI/VGA adapter, which is what I had been using previously, too). It doesn't matter which screen is in the VGA, the other one won't be recognized as even being plugged in. I tried switching to a standard HP monitor which supports DVI directly, and when I plug that in, it turns off the VGA and switches completely to the DVI (as in the Happ now tells me there is no signal). The Intel Graphics config utility only shows me "single monitor" as an option in any of the various configs I've tried. I've tried switching the BIOS from auto detecting everything to forcing the VGA to be primary and the DVI to be secondary, but there was no change in behavior. I've never had trouble getting dual displays to work on anything else, and have no idea what else to try. Any suggestions would be appreciated. This is running Win7, 2x4GB DDR3 1333, I3-2120, 128GB SSD, no optical, and, other than my attempts on the video config, it's standard BIOS settings.
Thanks,
Greg
