I currently use a 50' plenum HDMI cable to connect from laptop to overhead video projector to run PowerPoint with embedded videos. This works fine with no booster. I now need to add 25' feet to this arrangement as we are moving further away from the projector. Do I need a booster of some type or just hook it up with a coupler and go? Thanks.
You could try a coupler and additional cable but I think an HDMI booster might be required. One with its own power supply might work better than the ones powered off the 5v on the HDMI cable itself. http/www.hdtvsupply.com/hdmiextenders.html
So at the ceiling where the projector hangs, the Cat 6 would go into the receiver thence short HDMI to projector. On the other end, cat 6 to sender to HDMI to laptop? And, is the typical 100' of Cat 6 made up with ends that are compatible with the sender and receiver? Or, are there different configurations? So many questions...... Many thanks, Frank
