I tried last night but had two problems:
1. I don't have an unencrypted HDMI source. HDFury is supposed to send me a working HDMI input card any day.
2. The Blackmagic Intensity Pro 4K only works in the motherboard I'm using if the PCIe slots are set to Gen3. However, when set to Gen3, my video card doesn't work (GTX 960) and I have to take it out completely to get back into the bios using onboard video. I thought my processor, i7-3770K, supported Gen3, but perhaps I need a bios update.
I won't be able to get back to this until after the weekend. I leave early tomorrow for the
Central Iowa Home Theater Crawl.
I did take a picture of a bunch of HDMI inputs/outputs. From left to right:
HDFury PCI-MATRIX 44UHD (4 HDMI inputs that can be routed to 4 HDMI outputs - supports 4K in/out) - Not a capture card
Blackmagic Designs Decklink Mini Recorder (supports input up to 1080p30 or 1080i60)
MSI GTX 960 (supports HDMI 2.0, 4K)
Blackmagic Designs Intensity Pro 4K (support 4K input)
