I'll go forward and order the parts next week, once I set it up, I'll post back if it works and how well it works.
Hello,
I'm in similar case of you, I've a Switch (Marmitek Connect 740) and Splitter (Ezcoo EZ-SP12H21) both are compatible with 4k@120hz (with downscale to 1080p@120hz) and HDR/VRR but I'm stuck with the grabber, I'm looking if Ezcap321 is compatible with HyperHDR (on rpi5 for me) with 1080p@120hz
have you can test this ?
