After some joint debug, based on Parade's recommendation, the short term solution is not to write on the TMDS_OE register (0x40, offset 0x20)." apparently support for this was supposed to land late last year, but that's not at all certain..</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
