I have been working with a 3 monitor setup for over a year now, utilizing the VGA & DVI connections on my HP docking station in conjunction with a USB-to-DVI adapter. Two of my LCDs are 23" set at 1920x1080 and the third LCD is a 24" set at 1080x1920 (portrait). This has become my favorite monitor for viewing PDF & Word files as well as for browsing the internet on. This is the monitor I have connected through the USB2DVI adapter. The other 2 are landscape monitors and are primarily used for viewing spreadsheets, email (one on each monitor), and database programs. I cannot work any other way now! I have never experienced any issue whatsoever in using the USB2DVI adapter, although I did spring for the "Pro" version which supported resolutions beyond 1024x768. I am running an HP EliteBook 6930P with 4GB RAM. The 2x 23" LCDs are identical Acers, model S231HL, and the 24" LCD is an HP LA2405wg.
