I just purchased a Philips 19" hdtv. I have a Dell G260 desktop, and now want to replace monitor and use the tv as computer monitor. When I run sudo lshw, what am I looking for to identify whether I have a video card that is Digital Video Interface rated? Also, http://www.ehow.com/how_2321697_use-hdtv-computer-monitor.html calls for an HDMI to DVI converter, or cord. Where is best place to find this/these locally? Any help appreciated, Tom
