I bought 40" of HD loveliness last weekend and, so far, I'm very impressed even with the standard definition picture. I have the PC connected via the VGA port, at 1920x1080, for watching Blu-Ray and HD satellite broadcasts and, to me, that also looks good. So, am I likely to gain any benefit from spending an arm and a leg on a DVI-HDMI adapter cable to replace the VGA connection?
