Subject: Re: [PATCH v13 0/6] Add Synopsys DesignWare HDMI RX Controller
Date: Wed, 5 Mar 2025 01:59:07 +0100 [thread overview]
Message-ID: <1039aca7-89b9-44ef-9775-e7852e956362@timsurber.de> (raw)

Hi Dmitry,
I did some more testing. 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.
Best regards,
TIm
