1) What happens if my display name is not one of these mentioned ? E.g. searching for display in IOReg I get:

IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/BR3A@3/IOPP/H000@0/NVDA,Display-A@0

2) (Offtopic, sorry) Is there anything similar for DisplayPort audio ?

Thanks for the easy method. However, every method I use to activated the DP audio on my GTX 970 is pretty laggy, giving this error in console:

25-09-15 13:59:41,837 Console[803]: Failed to connect (_consoleX) outlet from (NSApplication) to (ConsoleX): missing setter or instance variable

Then the sound is laggy or robotic for a while. Any Idea on how to fix this?

Thanks in advance

I can't find it anywhere.
