Display cutting out
 

I'm on a Dell Latitude D630 running Win7/64. The adapter seems to install fine, and the picture/resolution looks good, but it cuts out frequently (2-3 times every 5 seconds or so.

I have updated my display drivers and the DisplayLink driver, but the problem persists.

The same monitor works fine on other sources, and I can even get an image to this monitor from the same laptop using the VGA out. However, being analog, the display isn't as crisp as the DVI via DisplayLink. Just can't get it to stabilize and quit flickering.
