Hi Vladimír, Sorry for the very late reply. Is there any chance you can retest with a 4.4 kernel? That should contain the following commit, which might make a difference for you. commit 1da7d7131c35cde83f1bab8ec732b57b69bef814 Author: Jani Nikula <jani.nikula@intel.com> Date: Thu Sep 3 11:16:08 2015 +0300 drm/i915: ignore link rate in TPS3 selection I tested with a thinkpad t450s and HP external monitor and it worked fine. Can you test it with latest kernel? Hello, I just tried to reproduce the problem with following configuration: BDW-U NUC, emulating eDP with external Display (HP ZR24w) 1920 x 1200 as principal display Attaching a 4k display (3840x2160). Using same command lines: Both are working fine with this software configuration: OS: Ubuntu 16.04 Kernel: 4.7.0 rc2 ++ Date : jun-WW24-01-11:31:29 --> Component : drm url : http://cgit.freedesktop.org/mesa/drm tag : libdrm-2.4.68 commit : fc09c5a author : Kenneth Graunke <kenneth@whitecape.org> age : 6 weeks ago --> Component : mesa url : http://cgit.freedesktop.org/mesa/mesa tag : mesa-11.2.2 commit : 3a9f628 author : Emil Velikov <emil.velikov@collabora.com> age : 4 weeks ago --> Component : xf86-video-intel url : http://cgit.freedesktop.org/xorg/driver/xf86-video-intel tag : 2.99.917 commit : baec802 author : Chris Wilson <chris@chris-wilson.co.uk> age : 1 year 6 months ago --> Component : libva url : http://cgit.freedesktop.org/libva/ tag : libva-1.7.1.pre1 commit : 453876f author : Xiang Haihao <haihao.xiang@intel.com> age : 4 days ago --> Component : vaapi (intel-driver) url : http://cgit.freedesktop.org/vaapi/intel-driver tag : 1.7.1.pre1 commit : 2975480 author : Xiang Haihao <haihao.xiang@intel.com> age : 4 days ago --> Component : cairo url : http://cgit.freedesktop.org/cairo tag : 1.15.2 commit : db8a7f1 author : Bryce Harrington <bryce@osg.samsung.com> age : 6 months ago --> Component : xserver url : http://cgit.freedesktop.org/xorg/xserver tag : xorg-server-1.18.3 commit : 9454cd5 author : Adam Jackson <ajax@redhat.com> age : 9 weeks ago --> Component : intel-gpu-tools url : http://cgit.freedesktop.org/xorg/app/intel-gpu-tools tag : intel-gpu-tools-1.15 commit : 3ce58b6 author : Marius Vlad <marius.c.vlad@intel.com> Please let me know if this configuration works for you |
