Yes, Barco is advertising the ICMP/Alchemy now with twin HDMI 2.0 ports (in addition to one pre-existing HDMI 1.4a port).

Where exactly are the twin HDMI 2.0 ports mentioned? ![[Confused]](confused.gif) Both the picture and the spec sheet show the same old "dual DP's + single HDMI 1.4a" thing. Same goes for their spec sheets for Alchemy-equipped Barco projectors.
Also, shouldn't it be possible to retain the locking DP ports since the DisplayPort standards supports the HDMI 2.0 signal anyway?
Edit: OK, found it. Indeed, gone are the DisplayPort ports:

Next-generation Barco Alchemy adds HDMI2.0
Now, Barco is taking the next step in this evolution, by adding support for HDMI2.0 on the Barco Alchemy projectors with ICMP. HDMI2.0 is the latest standard for bringing alternative content to cinema. It support HDR, HFR and has enhanced content protection (so-called HDCP2.2). Thanks to the next-generation ICMP, exhibitors can leverage the full benefits of alternative content by directly hooking up their 4K HDR - sometimes called 'UHD Premium' - sources to the projector. We added two HDMI2.0 interfaces to the ICMP, while keeping our legacy HDMI1.4 (and SDI) inputs; giving you the option to hook up 4 different sources. Thanks to the abilities of HDMI2.0, the 4K HFR and 4K3D capabilities that the projector and server already had; are now linked to a much wider portfolio of new alternative content sources.

Note, the HDMI 2.0 version of the ICMP is currently shipping. I've installed two already and am putting in a 3rd this week.
Be VERY careful of the HDMI ports on this unit. The connectors are flimsy and easily damaged. Use a "Port Saver" (typically about 8 inches long and flexible, Monoprice has them) in conjunction with whatever cable you are using. Be sure to use a product that will allow you to strap the HDMI plug onto the ICMP via the supplied screw (Extron make such devices but there are many others).
So, on your Christie, what is it you are concerned about? You can use the two DVI inputs to take your Oppo's inputs though just at 1080p/60, not UHD 4K. You can spend a lot of money on Christie's Quad-link solution but it isn't HDCP compliant and tops out at 30fps.
As for other IMBs (IMS2000/3000, Showvault/IMB, SX2000AR, SX3000), ALL top out at the SAME resolution of 1080p/60. I still have a request in to Dolby to implement the full HDMI 1.4 spec on the CAT745 and allow 8-bit 4K on it but given that it is discontinued, I'm not holding my breath but I get that question every year from a growing number of people.
The problem is, with the ICP, you aren't going to get 4K/60 on ANY DLP projector. The Barco ICMP can do it because it replaces the ICP and breaks the bandwidth barrier. That is why they can have HDMI2.0/HDCP2.2 ports. So, unless you are going to pitch your projector too, you are stuck at 1080p/60 on that projector until such time as Christie comes out with a solution. They do have an IMB S3 that is being paired with the new CP4325-RGB BUT that one will debut with an HDMI 1.4a port, not an HDMI 2.0. However, my birdies tell me that before the end of the year, it should have an HDMI2.0 option but it will be a hardware one on the new PIB. So, in order to bring HDMI 2.0 to a CP4230, they would need to come out with a retrofit S3 server (because nobody is going to design an S3 ICP for Christie but Christie so I suppose there may be S3 ICPs...we'll see but they would also need to come out with a new PIB to work with the S3 architecture.
The bottom line, it is VERY difficult to support 4K alternative content from anyone but Barco in the DLP world and I believe the newest of the new Sony's also has an HDMI 2.0 port.
