As I stated above ... I was using a 26" (really a 25.5") with a 20.1" secondary. But there was a problem... It would always shut off the second display whenever I restarted. At first I thought it was the ATI Hydravision drivers not liking the different resolutions. So, first, I tried uninstalling it to see if that helped. Next I tried using a 24" display from another computer for the secondary. This means both displays are running the same resolution (1920x1200). That still did not resolve the issue of the second display being disabled when Windows (Vista) starts. All I can figure is that my primary display's lack of an *.inf is keeping this setup from functioning properly. The primary display is a Vizio LMM26. Any ideas why this setup isn't working like other multi-display setups have in the past? At the same time, I've noticed a somewhat disturbing trend. Apparently Large LCDs were not selling well at all. So the companies, in a effort to cut production costs, have canceled the 16:10 aspect ratio displays in favor of 16:9 displays. Also the largest size seems to be 23.6", but I don't really want to downsize. And after looking around I found that there are a few "large" LCDs still available online (that aren't 30"). So this morning I decided to try a Hanns-G 28" (actually a 27.5" display) from NewEgg >> Newegg.com - Hanns·G HG-281DPB Black 27.5" 3ms Widescreen LCD HDMI Monitor 500 cd/m2 800:1 Built in Speakers - LCD Monitors It will run at the same resolution of 1920x1200 and has a set of Vista certified drivers. Here's hoping having real drivers, instead of running in "Plug an Pray" mode, will work.
