[mythtv-users] pcHDTV and HDTV

[Brandon Beattie]

Rule 1 for display device/resolution/(interlaced/progressive) is your
computer should be displaying whatever your true HDTV's native
resolution is.  Most devices are 720P for HDTV's.  Also, 1080i HDTV's
are often 1920x540, not 1920x1080.  There are several cards, mostly ATI,
that allow you to hook component video cables onto them.  If your HDTV
has a 15 D-Sub (VGA) connector just use that and any video card.  I know
of few HDTV's that only have component video connections.
