I'm recently looking for a KVM-over-IP device for a single computer connection. I'm especially looking for a device that is capable of transmitting high quality output from a VGA or DVI (the output will be mostly from 3D applications and videos), keyboard/mouse input and sound output. I presume that the overall performance of the KVM device relies heavily on the network bandwidth. I found several products that seem to transmit all those 4 components, but I cannot really imagine the speed/responsiveness of such connection.
So my question is: Are generally KVM-over-IP devices capable of such transmissions (3D games) in real time? (assuming the 10/100Mbps connection or higher).
I heard that some VNC clients (such as RealVNC) are usually used to control the KVM device - so are even these client applications designed to handle such requests in real time?
