Monitor doesn't receive signal

[tstephens]

Hi,

I just tried to setup my displaylink adapter. Windows is showing the 3rd monitor, but the screen isn't detecting any signal. I've tried plugging the screen into one of the regular display ports, and it works. So I know the screen isn't the issue itself. I also tried using a different monitor with the adapter (one that also works on a normal port) and was unsuccessful.

I'm running Win7 x64 - Nvidia NVS 4200 - the screen is a Dell U2410.
I've tried multiple usb ports and now I have it plugged into a powered usb hub to make sure power wasn't an issue.

I walked through all the steps on the troubleshooting page and everything looks good. Like I said, windows recognizes the screen, the display just doesn't seem to be receiving any information.

Any help would be appreciated!
Thanks
-Tom
