The DisplayPort host and device will negotiate how many channels are available, resolutions available, and so forth. They'll have a little electronic "tag" in the connector to tell the host and device it's plugged in, and that's about it for any electronics in the cable.
Connect macbook to monitor usb drivers#
My question: What happens if I buy a cable like this and connect it between my old MBP and my LG UltraFine 5K Monitor?ĭisplayPort cables like the example you gave are largely passive devices and so are bi-directional and don't need any drivers or such. I am therefore a bit confused: Mini-DisplayPort (a video protocol) uses a Thunderbolt connector and DisplayPort is embedded over USB 3-1/Type-C… Finally, the answer to this Apple StackExchange question says no but then says that "Thunderbolt is a protocol for combining PCI express data with DisplayPort video protocols" ( this web page explains the differences and similarities between Thunderbolt 3 and USB-C) and then says "DisplayPort embedded over USB 3.1/Type-C". This Apple KB (section System requirements and compatible Mac models, paragraphe before the last one) says no, but does not specify Mini-Display Port. This Apple StackExchange question does not really answer my question because it is about USB-A to USB-C. I wanted to know if through an adapter, I could connect the old MBP from its Mini-DisplayPort to the USB-C of the monitor and have a video signal. I have a newer MBP with 4 USB-C connectors that I use with an LG UltraFine 5K Monitor (aka. I have an "old" MacBook Pro (MBP) that has a Mini-DisplayPort connector.
