Hard to give a quantified "amount" but simply put, any hardware KVM I have used does degrade the image. To me it was too much - the image was fuzzy - but to a casual user it might not be a big deal. One solution I have found is to use a software KVM. http://synergy2.sourceforge.net http://quicksynergy.sourceforge.net I am using QuickSynergy to switch between my Mac and PC at work. Flawless except for a few things that I can work around. Check it out. Will.
