I have 4 PCs connected to my Dell UHD 27" monitor, Intel NUC i7 with Windows 10 Lenovo X1 Carbon work laptop with Windows 7Mac-Mini with CatalinaDell XPS 8300 with Windows 10I I bought a different brand of 4K KVM switch. The display quality was terrible and it didn't work at all with Mac switching time around 2 seconds - not lightning fast but not a problem either. Very happy with quality, functionality, size and looks (and lack of tone).
