Can I hook up two monitors to a Y-splitter using only one video card output(DVI or VGA) for a dual mon. combo?

I don't think you can do that with just a splitter since the video card will only output the same data signal to both monitors. So in best case you will receive the same image on both monitors.



If you really want to have dual monitor configuration with 1 output video card then you can opt for devices like Matrox DualHead2Go. But these devices cost quite a bit so it may be cheaper just to get a new video card with 2 outputs.
