Turned on my mac pro this morning & it's showing the display as 1280x720. What the hell is this?
OK, first things first. My display is the Apple cinema 27" with mini display port. It is plugged into my GTX 970 with a Display port adapter to the mini dp. My mac pro is a 2010, 2.4 quad core. Now it has never done this with this setup......never. Seems like every time I turn this thing on, I get a new experience. Never a dull moment. What is happening now. Oh, the driver installed is 378.05.05.05f02, running 10.12.4 Sierra.
