I previously had Radiance in front of HD621 with no problems.

In my current simpler setup, the Radiance isn't in use. If I try to switch the Mac Mini through the HD621, it is as if it has to keep reestablishing the handshake every 1-2s. No problem with direct HDMI into the TV.

I should try putting the Radiance back in the chain, but space is tight.
