Created attachment 26656 [details] [review] please try the patch against latest driver, thanks Created attachment 26664 [details] [review] please try the patch against latest driver, thanks Based on HDMI spec each HDMI source should provide HDMI identity, which is stored in CEA extension, otherwise we may think it is not HDMI device.
