HDMI Q&A - The One Connector World > MacBook and iMac have weak HDMI ouput with Router

Our office uses a Gefen 8x8 HDMI crosspoint router to distribute signals throughout our office to our TV's. We have a Blu Ray DVD player, HD Cable box, and laptops into the router and all works good. But the MacBook Pro, and iMac HDMI outputs aren't strong enough to get to our TV's.

We're using Comprehensive dual cat5/6 hdmi baluns. I tried Aurora baluns with adjustable pots to boost the signal, an hdmi DA with equalization but still can't get the Mac's to get through the system. If I plug my Mac directly into the router with HDMI, it works. My Toshiba laptop has no problem. I'm using cat6 wiring. The distance from our conference room to the router is about 30' of cat6. Back to our TV from the router is about 20'. I can't get it to work with a TV hung directly off the router either.

Does anyone know of a solution that would push that signal through without spending a fortune? Something that might regenerate or boost the HDMI signal enough to get through the baluns?

I'm tired of spending money on options that don't work. I need a proven solution.

Thanks.

Kevin,
If I were you I'd try Apple support. BTW - As far as I know, Apple does not use HDMI on any of their computers.

?? They use Display Port (DVI) on practically everything now.

To address the OP, I would probably try an HDMI booster. Unfortunately, nothing with HDMI over distance is at all proven and reliable. It's always a crap-shoot.

I'm using a mini display port adapter to DVI, then convert to HDMI. I also have one that goes direct to HDMI. I have tried putting the DVI signal into a Kramer converter that converts to HDMI. With all of these options I still cannot push the signal through like the Toshiba will. I also tried running a 25' HDMI cable across the floor and through the wall to the router. The signal shows up, then blanks out for a second, shows some static partially on the screen, comes in, goes out, etc. I ran this through a 1x2 distribution amplifier which didn't help.

My quest continues.
