I'm afraid there was a bit of misunderstanding. I was referring to the "Lager: Bad image quality when shown on HDMI display" issue, not the "DISPLAY-UNIT: Does not support 640x480 resolution" and "DISPLAY-UNIT: Does not support 16- bit for color numbers" issues. I should have been more precise, I'm very sorry about that. Could you please share your detailed test procedure, kernel configuration and test binaries for the "Lager: Bad image quality when shown on HDMI display" issue ? -- Regards, Laurent Pinchart
