Will do. I was a little too early. While preparing the patches I found that I still had the hack to force sink_is_hdmi = false in my test branch. Sorry for that. Removing this made the panel go black again, even with your latest proposal. So I looked deeper into your patch and it seems to influence the input formats only in dw_hdmi_bridge_atomic_get_input_bus_fmts()? While the problem I see is with output formats and we had worked on modifying dw_hdmi_bridge_atomic_get_output_bus_fmts(). BR and thanks, Nikolaus
