Status in HWE Next: New Status in linux package in Ubuntu: Incomplete Status in linux-oem-5.6 package in Ubuntu: New Status in linux source package in Focal: Incomplete Status in linux-oem-5.6 source package in Focal: Fix Committed Bug description: [Impact] Connect the 4K@60Hz monitor on WD19, the monitor can't light. [Fix] As per DP spec, at first check DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT. If DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT is 1, read the DP_DP13_DPCD_REV to get the faster capability. If DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT is 0, read DP_DPCD_REV. [Test] With the patches, connect 4K@60Hz monitor on WD19, the machine can output the video to the monitor and the monitor can light. [Regression] low, Just get one more DPCD from the extended register, compare them and get the faster one.
