    Good afternoon
    I have installed deepin 23 and 25 on my laptop, but after updating all the drivers, installing the NVidia driver etc, it no longer works with the second monitor via HDMI.
    It is recognized and everything, but it does not work, sometimes it appears on the second screen "out of scale" but it is set to 1080p

    Using an AMD/NVidia notebook

    Hello,

    Try these steps:

    Check NVIDIA driver: Run nvidia-smi to confirm the driver is installed.

    Use NVIDIA settings: Run sudo nvidia-settings to configure the display correctly.

    Disable Wayland: Edit /etc/gdm3/custom.conf and set WaylandEnable=false.

    Manually configure with xrandr: Use xrandr --output HDMI-1 --mode 1920x1080 --rate 60.

    Check DPI and scaling: Set DPI to 96 with xrandr --dpi 96.
