    DPI 1.2 detection problem

    GiovanniPaolo

      I have a Dell XPS 13 with 5500 HD Graphics. I'm using DP 1.2 hub to connect an external screen (using VGA). The n ative resolution of the external screen is 1600x1200. I'm encountering the following issues:

      1) The native resolution of the screen detected by Windows is 1920x1080 (this resolution is not supported by the screen actually)

      2) When the screen of my laptop and the external screen goes to sleep because of inactivity then the external screen does not come back on and is not detected by windows. Unplugging and re-pluggin the VGA from the adapter or the adapter from the DisplayPort does not work, forcing the detection with the "Detect" button in the windows screen resolution window does not work.

      Thanks,

      Giovanni
