HP P7-1414 tower AMD A8 Radeon HD 7560D ASUS V236H 23.6 monitor 1920 x 1080 resolution.

When I insert a KVM switch, it loses PNP and max (usable) resolution reduces to 1440 x 900. I do not have this problem with my HP DC7600 with Windows XP. My XP machine lets me set the resolution to what I want and it stays there whether the KVM is there or not.

What can I do to fix this so my new machine works with the KVM switch?

The video resolution issue is the number one issue reported regarding KVM switches with Windows 7 and Windows 8 systems.

Caused: The KVM switches does not pass correct EDID of the display/monitor to systems connected to the KVM switches.
Solution # 1. Adding an EDID emulator in between each connected systems and kvm switches

Solutions #2. Upgrade or replace your KVM switch with Video DDM KVM or "DDM class" KVM switches . The Video DDM= Full-time All DDC-EDIC function which provide dynamic EDID feeding to each connected systems of KVM switch.
