I know there are a few questions here that ask about dual monitors but my problem is a little different. My desktop has only one DVI monitor input. I am using the DVI monitor input for my current monitor. I have another monitor which uses VGA.
I am hoping that I could have dual monitor for my computer, like I could extend my computer's screen space to two-monitor space.
The problem, however, is since my desktop only has one DVI monitor input; I can only use one monitor at any one time. Also, one of my monitors uses DVI and the other uses VGA. Most Y-Splitters come in the form of either both DVI or both VGA.
What should I do in my case if I still want to have dual monitor display?

Best and most reliable option is to buy a new graphics card if you have a spare slot. Graphics over USB is woeful. Watching content that refreshes quickly (ie, Video) is not worth it. The cheaper end of graphics cards however are generally quite acceptable. Choose one that supports DVI-I, then you can use a DVI/VGA adaptor for your VGA monitor, later being able to use it for DVI if needed.
A Y-Split will not extend, only duplicate the signal (unless you have a dual DVI port) however I doubt this.
