Hi Ville, > Well, just to check the details of your particular cable/dongle, > maybe you can post the dmesg with drm.debug=0xe with my branch? > Or at least the parts that refer to DP dual mode adaptors. Here: http://filebin.net/gd91wnltky/dmesg.4.5.0-rc4-g32fa589.txt I'm assuming the most important parts are: [drm:intel_hdmi_dp_dual_mode_detect] DP dual mode adaptor (type 1 HDMI) detected (max TMDS clock: 165000 kHz, TMDS OE# control: no) [drm:intel_hdmi_compute_config] picking bpc to 8 for HDMI output For the record, I'd call my adapter a «cable» and not a «dongle». I had thought it was completely passive; if there's any active circuitry inside it it must be really tiny - it'd have to fit inside the rather standard-sized HDMI/DP connectors in the ends.
