So you want to be a sysadmin? Official IRC Channel - #reddit-sysadmin on Official Discord - • •. (Solo non-profit 'IT Manager' here - it's all sysadmin to me.) I have a Mac Mini and a 50' Panasonic plasma screen.

When I directly connect the Mac and the screen all is well with the world - I can use HDMI on both ends or HDMI out of the Mac and an HDMI->DVI adapter to the DVI-IN on the screen. When I put ANYTHING else in the chain, like the HDMI->UTP->HDMI balun or a 2-1 HDMI switch, I get nothing.

Due to the size of the screen and the conference table in front of it, I can't run straight HDMI from the Mac to the screen. Research leads me to believe it's because Apple is rigorous about HDCP, and the things I'm trying to include show up as HDMI repeaters but Apple has chosen to disable the signal for all repeaters. (I'm doing all this to run Windows 7 via Base Camp on the sexy hardware, BTW.

Mac computer for gaming. Otherwise I wouldn't bother.) While my scenario involves a static computer and display, I'm sure someone out there has accommodated Mac guest computers or something. What does it take to make my Mac show up on the big screen? I don't quite follow the 'size of the screen and table in front of it' bit. You can't just use a longer cable? It doesn't sound like a switch is a required component of your setup, but I'm not sure why you're trying these various devices in the middle. I don't know much about HDMI, but have never had a problem connecting April 2010 or newer hardware (13' MBP, 13' Air, 15' MBP, 15' Retina MBP) to a TV via HDMI, but i've never had a reason to run anything else in the middle of the chain. Are you sure this is a Mac-only problem?

I'm wondering if it's a common thing to HDMI devices with HDCP, which means you'd have more things to search on rather than Mac-specific HDMI foibles. Size of the screen = we can't be too close to the 50' plasma. Table in front of it = it won't do to have a new cable run in the open. This setup wasn't part of the original space design.

I have CAT-6 running through conduit from the conference table to behind the screen, but there's no HDMI or DVI run. The baluns are inherent to what we have, and I'm not sure an HDMI connector would even fit through the conduit.
