That the Apple TV did not work was a bit misleading. It was just, that the Apple TV defaulted to 4:4:4 Chroma which does not work at all for me. (The same happens using the vendor driver). When I changed the EDID to match the vendor driver the HDMI handshake happened with 4:2:0 chroma, where I could verify even 4k60fps using your driver, nice! So the remaining problems I see are: - 4:4:4 chroma not working in any resolution - 4:2:2 and RGB not working in 4k60fps (is this a hardware limitation?) A possible workaround could be to disable these non supported formats in the default EDID.
