i just installed a cheap kvm. so far so good, no display issues yet. however 2nd pc probably won't get used much. only glitch was mouse didn't work straight away when i swapped over.
interesting side effect, as the kvm is on the desk and i have the wireless mouse plugged into it, the mouse now works a fair bit better.
mint is running nicely on the old pc. next on the list is to dual boot an old work laptop.
