The new HDMI spec will support signals of 4k x 2k. Press release here (http://www.hdmi.org/press/press_release.aspx?prid=93)

Would be a good feature request for Scarlet and Epic.

I would hope that the industry moves away from the licensing / HDCP nightmare that is HDMI and move on towards an open standard such as the emerging Displayport.

Yes this would be much better. The digital "handshake" between the player and the display can cause some major problems...sometimes. But HDMI is pretty much the standard. Doesn't using a HDMI to DVI cable work with the RED. I've always used HDMI to HDMI and I think the DVI port doesn't need to see the info like HDMI does.

HDMI 1.0 to 1.3a and DVI are built on the same digital interconnect, or a TDMS digital bitstream. DVI can actually use dual TDMS bitstreams, hence the name "dual-link DVI", which allows it to go up to QWXGA resolutions, and higher, where a single link allows up to 1080p or 1920x1200 for computer monitors. I believe HDMI 2.0 will address higher bandwidths.

HDMI to DVI adapter will work just fine, as long as the source does not include HDCP handshake, which the RED cameras will of course not employ. I don't know enough about HDMI 2.0 to know what it can or can't do, but do know that I'd rather move towards an open Displayport platform, than the license hungry HDMI consortium. I admit I am biased against HDMI due to headaches it has caused me, professionally, in consumer video systems. Apple, for those that have not noticed, have dropped native DVI support and are moving towards Displayport with their new machines.

At this point the move should be to DisplayPort. Its bandwidth is much greater than HDMI.
