Here's the situation, just purchased 2 Dell U2412 monitors. I want to be able to use them for both a PC with dual DVI connectors and the mini. My understanding is that the u2412 has a dvi and displayport connector. Wanted to use the monitor input selector to act as a switch between the 2 computers. My original thought was to connect the pc via dvi and the mini through the displayports on the monitors. The TB/mini displayport to displayport is straight forward. It's getting the signal from the HDMI connector on the mini to the displayport on one of the monitors. Everything I see looks like its displayport -> HDMI and are not bidirectional. The only solution I can see is to get 2 dvi -> displayport cables for the pc connections and convert the TB & hdmi from the mini to DVI. This just sounds counterintuitive. What am I missing here? Thanks for the help for a mac newb.
