I have the SA240Y monitor. It worked fine but one day started to be very poor resolution.

See the image for what I'm getting. I am connected via HDMI cable and using a Lenovo Thinkpad X1 and Windows 10. 
It's not as bad in the image as what I'm seeing live. Looks like a herringbone pattern.

    Please provide the complete model no of your computer.   If possible try to use an alternative monitor to check whether you are facing the same issue.

    Try windows x 
    go to device manager 
    expand display adapter
    right click on display driver - uninstall

    Uninstall the display adapter from device manager

    Check to see if the correct display adapter is still in Device Manager. That looks like it may have been reset to the Basic Display Adapter, which has fewer colors than the correct one.

    I think I found the problem. It can't handle the 2560x1440 resolution that my HP monitor uses. It's max is 1920x1080. I'll stick with the HP for now.

    Thanks both for your replies.
