    [drm] HPD interrupt storm

    hello

    I have problems with a new monitor and HDMI connection to the laptop, when I connect the external monitor AOC 22BH1 21.5" no signal, can be a problem with HD intel graphics

    Hardware
    > Lenovo Laptop V110 15,4"

    External monitor > AOC 22BH1 21.5"

    OS > Xubuntu 16.04

    kernel version > 4.15.0-65-generic

    kernel.log >
    drm] HPD interrupt storm detected on connector HDMI-A-1: switching from hotplug detection to polling

    glxinfo | grep "OpenGL version" >
    OpenGL version string: 3.0 Mesa 18.0.5

    lspci |grep VGA >
    VGA compatible controller: Intel Corporation HD Graphics 520 (rev 0a)

    I have installed the latest intel drivers via > intel-graphics-update-tool_2.0.2_amd64.deb, intel you have abandoned them long ago

    Any solution?

    Thank you!
