Setting correct monitor resolution in Vista SP1
Posted on 2008-10-20
I recently purchased a new PC and monitor. The PC is a self build that uses an nVidia on-board graphics chipset. The monitor is an Acer v223w 22 inch wide screen with an optimum resolution of 1680x1050.
With the monitor connected to the PC I can set the correct screen resolution in Vista and all is grand. However I use a Dynamode 4 port KVM as I've several PCs. When I connect the PC via the KVM the resolution in Vista changes and I'm no longer able to select 1680x1050 as one of the resolutions and have to settle either for something less or something greater than the optimum resolution, which looks pretty rubbish on the monitor.
Initially, after I'd connected via the KVM, Vista had changed the monitor driver to 'Generic non-PnP monitor' so I downloaded and installed an Acer driver for the v223w monitor and selected this driver from the list of offered drivers. However it still doesn't allow me to set the resolution to 1680x1050.
I tried reconnecting the monitor directly to the PC and once again I could select the correct resolution. Connect it back to the KVM and 1680x1050 is no longer an option.
Can anyone tell me how I can force vista (or the nVidia drivers) to give me a resolution of 1680x1050 when I'm using the KVM?
