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,

calls for an HDMI to DVI converter, or cord.  Where is best place to
find this/these locally?
Any help appreciated,
Tom
