I have now tried two KVM's for switching between my PC and Mac mini G4 at the office without success. The first, a Belkin Flip with USB, worked but would not allow my 17" MAG display in it's native 1280x1020 resolution. The second, a TRENDNET TK-207K, worked fine at first but once I try to switch back to the Mac, it shifts the display into a refresh rate that it won't support and - no picture. (/sob story) Can anyone point me to an inexpensive KVM that successfully switches between PC and Mac without these kinds of issues? Thanks!
