My Macbook Pro (unibody, mid 2009, 13") supports the 1920x1200 resolution of my screen, using the VGA display port adapter, but when I connect that through a simple USB + VGA KVM, the resolution becomes limited to 1920x1080, ruining the whole experience.
I'm guessing it happens because the Mac can't figure out what kind of screen is attached to the cable.
Is there a way to work around this?
I've tried SwitchResX but it didn't help. I would add the resolution, but it still wouldn't show up on the list.
