Also, are two of the monitors identical? Tonga only has two independent non-DP clock sources so it can only driver two independent sets of non-DP timing. Since you are using 3 non-DP displays, at least two of the displays need to be using the same mode. You may have to manually set the mode on the 3rd display using xrandr to make it match the mode selected on one of the other displays.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
