• Monitor Low resolution - Frequency too high

    I am running with 2 external monitors, one by HDMI the other by VGA. The monitor that is causing trouble is the VGA one. But are the same model, and both work with HDMI.
    However when I plug in the VGA cable, the monitor loads at 1024x768.
    Using xrandr and cvt I set a new mode for 1920x1080.

    cvt 1920 1080 60
    # 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
    Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
    xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
    xrandr --addmode DP2 1920x1080_60.00
    xrandr --output DP2 --mode 1920x1080_60.00

    However this causes me to to get the error.

    Frequency out of range: 68.5 KHz / 59.8 Hz. Please change the display mode to 1920 x 1080.


    This occurs with Gnome, XFCE and i3.
    I have tried swapping the monitors around, but whatever is VGA has this issue.
    Edit: Command information

  • I have a startup.sh script which consists of

    xrandr --output eDP1 --auto --primary --below HDMI1 --output DP2 --auto --right-of HDMI1

    Which works correctly, and positions everything where it should be. However the DP2 monitor resolution will not allow 1080p over VGA.
