Mini DisplayPort to Mini DisplayPort on Dell Monitor not working using Thunderbolt
I have a Mac Pro 2013 that I am trying to connect to two Dell U2414H monitors. I am using Apple Thunderbolt cables to connect from the Thunderbolt / Mini Display Ports on the back of my Mac Pro to the Mini DisplayPorts on the Dell monitors but the monitors do not see a signal. I made sure I'm on the right input on the monitors but nothing. I even tried using only one monitor and it also doesn't work. It knows there's a connection but does not see a signal. But when I do use a Mini-DisplayPort to DisplayPort cable (the one the monitors came with) it does work. Problem is those cables are too short for the location I need them and I already spent $60 on Thunderbolt cables and would hate to have to spend money on longer Mini Diplayport to Displayport cables. Does anybody know if a Thunderbolt cable should work and how? It was my understanding that a Thunderbolt cable also acts as a Mini DisplayPort cable? I contacted Dell and they said they don't know how the Mac computers work....Thank you.
