This is probably related to an old question but here it is. We are using a “temporary” cheap LCD 720p tv that has one HDMI input. When we got that TV (it replaced an old CRT that died) we got a new hi-def cable box and connected it with the supplied component cables. I noticed the picture wasn’t as good as I thought it should be so we switched to HDMI and this resulted in a big improvement. We just got a blue ray player (replacing an old DVD player that died, see a pattern here? DVD was connected via S video), would we get as much as we can out of the blue ray paired with our cheap TV if we connected it via component video, or would HDMI be better? Guess I should try both to see if I can see a difference. Component is the only thing available without adding a selector switch, (I don’t really want to add a selector switch). I am hoping the lower component quality from the cable box was the fault of the box and not the TV. A new TV is planed sometime soon so this is a temporary situation.
