It's the same issue with the opensource which works correctly only @60 Hz... I fixed the problem by forcing a resolution with grub. But impossible to solve the issue with the xf86-video-ati driver. Also tried the git version. Remember, no issue with windows & linux with Catalyst fglrx driver so I do not trust a hardware issue. There must be a différence in refresh rate management if catalyst wedge to 144Hz immediately after installation while the opensource driver made a bizarre 139Hz with artifacts (see attachments). Can be an important point to clarify: I use DisplayPort 1.2.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
