--- Comment #4 from Harry Wentland harry.wentland@amd.com --- Are the monitors set to DP input or to auto-select? If they are in auto-select will setting input to DP help?
I've seen auto-select mode have problems with DP many times, especially with scenarios like coming back from DPMS or S3 resume.
