Given that development on Modul8 hasn't been very active for quite some time, I know this is probably futile, but just in case, I'm going to post this anyways. In addition to two Radeon HD 5770 cards, I have a Blackmagic Intensity Pro installed in my Mac Pro. I use the Intensity for capturing HDMI in which generally works very well. In addition to the HDMI Input, the Intensity Pro also has an HDMI out however it does not function as a regular monitor output and instead only works with software that supports it like Final Cut Pro, etc. I don't know if it's technically feasible, but it would be awesome if Modul8 had the appropriate drivers to run this output as well. As it stands, my Mac Pro is out of PCI slots so this would essentially give me another output whereas I'm maxed out otherwise.
Probably not going to happen (or even get a response from the devs, I know) but thought I'd post it just for the heck of it...
