Question about Aten CS692, 2-port KVM

I don't quite understand your question, because this is also an HDMI switch. Do you perhaps mean a splitter? There is a lot to consider with HDMI and this part is quite simply built and probably not for all frequencies and resolutions. For me, it very rarely messes with the keyboard and I have to switch back and forth (possibly because I have sent a command of some kind). I use the CS692 to connect the 27" HD screen including mouse and keyboard from two computers (business/private). I'm quite happy with it, except that the cables could be a bit longer.
