Used between a PC and a Mac mini, the HP 2310ei screen, brand white keyboard and mouse Essential b without Logitech brand line, no problem of communication between these 3 devices, against the speakers Altec-Lansing 2.1 only work with the PC, a try with other HP has been achieved, but not conclusive, maybe a parameter to change the side of the Mac mini I missed? I think pas.Ceci said, very good price / quality ratio for this DS-11802-1 DVI switch.
