Sadly I don't see anything obvious we could use as a hint to ignore the dual mode adapter's limit. I was hoping the VBT would declare the port as an internal HDMI port (which it does) *and* it would declare a TMDS clock limit >165MHz (which sadly it does not) :( Well, it does say the limit is 0 ie. "platform max" but that's not a very strong hint to indicate that someone actually tested the thing with a >165MHz clock. Could be just they were too lazy to put in any real number and so left it at 0. So I'm not keen on including that as a valid value in such a heuristic. Feels like that could backfire on us.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
