Trouble with Mac Mini Late 2012 to 4k Asus PB287Q Monitor
I have spent hours reading about this, trying to get it to work, and can't. I was hoping someone could help. Here's the problem:
I connected the Asus 4k Display via Mini DisplayPort to DisplayPort. The default resolution is too low (2560), so I installed SwitchResX, as so many have recommended. I configured it for El Capitan, and then set up a custom resolution: 3840 x 2160 @30Hz.
Running this resolution, I get screen disturbance on the Asus, as well as my other HDMI (lower resolution) display. Even disconnecting the HDMI display, the disturbance takes place on the 4k. By disturbance, I mean that the mouse is a very large square (rather than a pointer), and dragging windows results in fragments of those windows being repeated on the screen (not clearing off of the screen). There's also a bunch of black and white patterns appearing towards the bottom of the screen. Other than that, everything looks perfect! 😉 But in all seriousness, it does: refresh rate is good and the resolution is otherwise superb.
I've also tried a lower refresh rate (down to 10 Hz), and had the same problem. I also tried 1080p HiRES, same problem.
Here's the craziest part: I connected my 2011 MacBook Air, and the **** thing powers up the display at 3840 x 2160 at 30Hz PERFECTLY!
Any answers?
Here are the specs:

2.6 GHz Intel Core i7

Intel HD Graphics 4000 1536 MB
THANKS SO MUCH!
