Cant resolution: KVM + Desyatochka, who faced?

Question

Windows

There are two machines connected by a KVM switch, a Samsung 2243nw monitor (native resolution 1680x1050).
On an older typewriter - Piggy, all in a bunch.
On the other - Ten, sure that the monitor needs 1920x1080. When setting the normal resolution in it, the screen stupidly flattens, the monitor still sees that 1920x1080 is coming to it, Desyatochka is sure that the size of the desktop is just that. Video - built-in Intel, the driver is fresh.

Are there other settings in this shaitan system that you can hit with your foot and make it feel good? The current control panels hide settings so carefully that I can't be sure I've tried everything.

KVM checked: the picture is similar on D-LINK PS/2 and ATEN USB.
