And unfortunately your card is listed as hdmi 1.4, but (as is very often the case, as this is allowed per hdmi spec) it's one of those old pseudo-hdmi 1.4 implementations which support some hdmi 1.4 features almost noone ever cares about but does not support the higher link rates introduced with even hdmi 1.3, so the 2560x1600@60Hz and 3840x1260@30Hz modes are not possible.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
