I want to install 2 LCD screens in our church sanctuary(52" dia.) I don't want to lose quality, and my run has to be I think about 75 feet to a computer and DVD player. Best Buy only has 35 foot lengths. Do you know where the best place to look for them? They need to be connected together (25' apart) and then 1 run to the back of the church. Any suggestions on installation? We haven't purchased anything yet but will be soon. Thanks.
You will need to get an HDMI coupler. HDMI is not meant to go that distance by itself. 30 feet is a good rule of thumb before adding couplers. You might be able to find a wire longer but it won't work with out a booster.
