Can't get 1440x900 resolution when using KVM switch

    I have two laptops connected to a keyboard, mouse & monitor via a usb kvm switch. Both of them are ok using 1440x900 screen resolution when connected directly to the monitor but one of them does not have that setting when using the kvm switch.


    Could understand why it might not be available at all or neither worked - is there a way round this?


    Thanks in advance for any assistance.

    It could be the Graphics cable between the problem laptop and the KVM that causes this. Some cables don't have all the pins connected and this can stop the computer recognising the Monitor and then using the wrong resolution. If possible swap the graphics cables or laptops over and see if the problem moves too.

    Thanks for the quick response.


    I tried switching the laptops/cables over but same outcome. The resolution settings were still not available while the other laptop continued to work fine. I also double checked connecting the laptop to the monitor directly and it automatically picked up the monitor (Samsung S19C450) and switched to 1440x900 resolution.


    Any other ideas?


    Thanks in advance!!

    Aside from swapping cables, have you tried moving the laptop to the other port? ie: If port A is working at the correct resolution and port B is not, then move the PC from port B to port A.
