Hmmm...everything I've been reading online says DVI shouldn't be too long, but HDMI should be able to handle runs of up to 15 meters or more.

No TV yet. But I'm trying to figure out a way to run cabling in-wall for the new place. If I'm going to run speaker cables, s-video, component, etc, I might as well get the HDMI cable run at the same time. That way when I do get a tv, I'll have all the connections that I need.
