Do HDMI "repeaters" really work?

Question

I'm no pro, and I've got to hook up a DVI video source to an HDTV that's about 40-feet away. I need to purchase the cables and I see on Amazon that I could buy two 25-foot HDMI cables plus an HDMI repeater -- but I've never used these repeaters (and I've never tried to connect to an HDTV so far away!).

Does 1080p really work across that far of a distance?

Answer 1

forget the repeater buy the cable. distance of 40' is not an issure here with hdmi

Answer 2

You can just purchase one cable.  Check the link below.
