Like stated in the header. I have bought recently a KVM switch degined to connect 4 USB devices to 4 computers and switch between them. One of my laptops have additional monitors attached and unfortunatelly this additional monitor is unavailable for the mouse. Is this a issue concerned to my HD 4600 or I should rather return the KVM ?
Please better explain yourself. If the KVM had the keyboard and mouse connected to it and it is currently supporting PC 1, then, regardless of the other monitors connected to PC 2, PC 2 will not be able to do anything via its other monitors -- unless a separate keyboard and mouse is connected to PC 2. The keyboard and mouse connected to the KVM are only available to a OPC when that PC is the PC being supported.
