I have 2x 24" HD monitors. Each has VGA, DVI and HDMI ports. I want to use both of them without mirroring. I do not want to use my MacBook's own screen (it will be closed) when I connect the others.
I have managed to connect the screens by using one DisplayPort->HDMI cable and one HDMI->HDMI cable. That works fine, except, because the HDMI port is on the other side of the laptop to all of the other points I need, it makes the desk a bit messy.
So I bought a second DisplayPort->HDMI cable. When I connect the second one, the system freezes up and the second monitor stays blank.
My research suggests that the MacBook Pro 2015's GPU is meant to support one DisplayPort monitor plus its own screen - but can I configure it to use two DisplayPort monitors and not use its own screen?
(There are lots of similar questions but I couldn't find one that specifically deals with 2x DisplayPort cables)
