I'm about to buy a new JVC Projector, and need 3 full bandwidth HDMI 2.0 ports. From the specs, it looks like the MC-700 has exactly what I need. However, I have an XMC-1, and don't want to give up Dirac Live, even for a couple of months while I wait for the the new HDMI board to become available. What I'm wondering is if I can use the XMC-1 just for HDMI switching. I'd use the full bandwidth HDMI output to go to my JVC projector, and the other HDMI output to go to the XMC-1. That way I could let the XMC-1 do all the audio processing, while still getting full 4k with HDR and copy protection. Then, when the new HDMI 2.0 board releases, I can sell the MC-700 and recoup some of my cost, while a board member gets a great deal on a lightly used processor.
So, would that work, or am I way too far out in left field?

Look at a HDFury.

I have. Here's the problem: |

But your only going to one output device from one input device . ie 4k player to projector and split audio to your XMC-1. Are you going to hook your 4k player to your tv . Maybe look at the model they call the Integral. I am not an exprert but this looked like it would solve the problem short term. www.hdfury.com/shop/splitters/integral-4k60-444-600mhz/ |

Maybe I'm misreading, but since I'm going to have 1 input going to 2 outputs (video + audio), I read that to mean that it will max out at 4k@30hz 4:4:4, or 4k@60hz 4:2:0. The Integral is what I was most interested in, so if I'm mistaken, it would be the ideal solution for me. |

Okay, I just spent some time on the HDFury forum, and I guess to make this work, I'd need the Integral to split the signal, and the Linker to downconvert the signal for the XMC-1. Boy, that complicates the signal path, and also starts to get expensive.

Maybe foregoe the HDR metadata for the JVC Bluescale and feed it SDR BT2020 WCG [which isn't as good as a lcd panel for HDR's highlights] . Consequently you can always send a primary 18gbps signal through alternatively [with HDCP2.2 stripping] if you want to run a custom gamma curve depending on your JVC's generation [ And feed it the HDR anyway] Of course the integral is limited to 2 hdmi2.0 in only and you have 3 sources - too many handshakes is not as reliable  |

Just FYI...... Before you spend the $$$ on an HDFury..... you do know that Monoprice makes a HDCP 2.2 to HDCP 1.4 converter box for $39, right?  (And, yes, I believe it is limited to 4.2.0 - but, then, 4k Blu-Ray discs are only 4.2.0 anyway... ) Okay, I just spent some time on the HDFury forum, and I guess to make this work, I'd need the Integral to split the signal, and the Linker to downconvert the signal for the XMC-1.

cwt and Keith - thank you for your thoughts. Maybe I need to step back and look at what I would lose if I do nothing, or settle for the less expensive HDCP 2.2->1.4 converter while waiting for the new XMC-1 HDMI board. - UHD Blu Ray - XMC-1 overlay. The player has two HDMI outs, one can do directly to the projector, and the other to the XMC-1. I can easily live with this in the short term.
- HTPC - 10 or 12 bit color. If I'm not mistaken, the XMC-1 can do 4k@60hz, as long as it's 4:2:0. Can someone confirm this? Also, is there anything else I risk losing?
- PS4 Pro -
 I don't know what I lose here. Do any of the games require HDCP 2.2 for 4k playback? Does anyone know how the PS4 behaves when it sees HDMI 1.4
Thanks for the input! |

That device is $219, and only has 1 input. I'd need 3, and at that point, I don't have enough inputs on my projector to support all the devices. |

What I actually need is a 4 in, 2 out. That way I can send full 4k+HDR to the projector, while I send the audio to the XMC-1. With one out, my HDMI chain gets knocked down to HDCP 1.4. |

The only thing you are going to find like that is an actual matrix. This would probably push above the price point you are trying to hit. Especially in the 18GB world. |

That is indeed what I'm finding. At this point I'm going to wait it out as long as I can. Hopefully the HDMI board will be available this summer, or I'll have to figure out something else. That would suck. |

how many 4k sources do you have. The XMC-1 can handle 4k to some extent as long as hdcp 2.2 is not present.

This is relevant for the ps4 bluescale emotivalounge.proboards.com/thread/49852/4k-60fps-ps4-pro?page=1&scrollTo=883684Apparently you can switch hdcp on/off to get 2160p with rgb rather than component y pb pr  And switch to hdcp1.4 ; community.eu.playstation.com/t5/PS4-Support/PS4-Pro-HDCP-2-2-issues/m-p/24675639Seem to recall Andrew Robinson testing the XMC1 with 4k/60 but ime not 100% on this .The reason I like the integral is it can give you wide colour gamut in BT2020 ; rather than blurays rec709 ; and that's more important imho than HDR in a JVC that hasn't got the nits of a led or even oled .. Why everyone was so eager to see oppos hdr metadata stripping for their JVC;s ; one less box ; its a work in progress last time I looked |

Sorry to be a little off-topic but may I know what JVC projector you have?? I'm enjoying a lot my old JVC DLA-HD1, and I totally love its 'D-ILA' cinema look and its then, almost perfect black levels (LOL..I know that it cannot compete at all with current OLED TVs) But how's the state of these projectors: is it still DILA/SXRD tech the more cinema-look big image projector tech you can get and what about resolution (I read that they're not yet true 4k?) and what about lumens and black levels, I guess these should be quite awesome nowadays. Thanks!

Thanks! Ive got a DILA x7000 jolaca ; it replaced an Epson 9000 [5030 US model] and its contrast is in another league [which helps with the high dynamic range of UHD ] . Your hd1 is still a cut above for on/off contrast ; you just need a model with hdmi 2.0a and hdcp2.2 for UHD.Its high lumen output[new type of lamp] is handy for UHD sources though panels have advantages here . The newest generation that bluescale is looking at has better compatibility with setup [and better game lag figures ] but either generation has full 12bit throughput ; which is handy for Panasonic uhd players that upscale 10bit uhd discs to 12bit :)They just got a firmware upgrade for 10bit for older panels/projectors . Yes they are still e-shift but this has been refined over the early versions and e-shift 4 is the rough equivalent to 3k resolution . More important is the Wide Colour Gamut ; a lot of UHD discs are mastered from 2k intermediates then upscaled which mitigates things but still can look spectacular .. |

And switch to hdcp1.4 ;
