    Couple of questions:
    1) Please confirm that, when fully populated:
    Screen 1 is the USB-C
    Screen 2 is the HDMI
    Screen 3 is the Mini Display port

    2) On start from sleep my USB-C video feed pops right up, and in display settings it shows a "2nd Monitor" and there are two shown in Device Manager>Monitors, but the 2nd, HDMI feed does not display anything. I click the detect button and it says that it didn't detect anything else.
    I unplug the HDMI cable, the second monitor disappears from both display settings and Device Manager.
    I plug it back in and it usually pops back to life.

    Note: This appears to have resolved with additional memory allocation for the video driver. That or the computer knows I'm writing about this topic and has straightened itself out. Really either are equally likely.

    3) I get nothing out of the Mini Display Port. Solo, dual, or three monitor setups, Startup, hot plug, nothing. Using an Amazon Mini to HDMI adapter cable and that is all I have right now having been blissfully able to avoid display ports in any fashion thus far. All my monitors are the same, but I did try it on the kitchen TV with no success.

    Thoughts on 1 & 3 please.

    Only one screen would show until you are logged in.

    Also, please make sure you updated to the latest graphics driver:

    1.) It depends on how you are arranging them, there are no fix settings for which is which.
    3.) You need either a mini DP to DP cable, or an active mini DP to HDMI adapter, to get a working output.
    such as:

    I think this is the only one that I would recommend. :eek:

    Ken-
    Well, to the best of my knowledge (presumption) the MDP to HDMI would (have to be) be active, but I'm happy to try yours. Except your link didn't.
    Driver is current.
