Yes, much more! Maximum 1080 resolution is still not fantastic compared to the abilities of, eg, Apple Cinema Displays (up to nearly 2000), but I'm guessing you're not doing fine photo processing at that distance. Gives you the opportunity of using the PC as a media server as well.....
Anyway, back to the question - check your graphics card has a DVI or HDMI out, and if not get one, USB or PCI - then depending on what it has, get either an HDMI cable, a DVI-to-HDMI cable, or a DVI-to-HDMI adapter, to which you can connect an HDMI cable. Does that make sense?
