    LG 24MK400H-B Hdmi-no signal/Vga-bad image

    Hey,

    Changed my monitor recently to LG 24MK400H-B and the image is really bad whenever anything moves(scroll, mouse, videos).
    I am currently pluged with the Vga since the Hdmi doesn't work at all.
    I have a gtx960 and already updated my nvidia drivers. Currently am using nvidia-driver-435.

    Thanks

    Where did you get that driver from?

    What is the max size of the monitor's resolution? Some cheaper VGA cables are do not do well on larger resolutions.

    I meant that when i plugged it with the HDMI cable it didn't work as the monitor said "No Signal". Haven't tested yet

    Open software and updates/sources-additional drivers and see if proprietary drivers are available or installed. It appears as if you are using the open source driver.
