    I used to be able to have both display outputs working. Now DP does not appear to output. On boot up, it briefly shows a compressed band of gibberish, then 'input not detected'

    Connected direct to HP envy 27" 4k display with mini DP to DP cable
    And also when connected with HDMI, the max resolution it will output is 2560 x 1440 instead of 3840 x 2160.

    Intel display drivers are up to date. Attached.
    I have cross checked my display with another PC.
    I have not cross checked my DP cable. Seems unlikely.

    Help.

    What did you use to generate the report you included in your post? I didn't know that the Atom processor used Intel HD Graphics 400 - I`ve only seen just Intel HD Graphics specified.

    Can the report tool provide more about power management than just "Power Management Support?" Specifically, can it report if S0ix is not implemented?
