Second Monitor (MiniDisplayPort - HDMI) Blacking Out Intermittently

I recently added a second monitor using a MiniDisplayPort to HDMI adapter on my (late 2014) Mac Mini running Ubuntu 18.10. The screen normally works fine, but will once in a while go black for a few second and then turn back on. This wasn't too much of a problem, but now it's doing it like every minute or two, which is really frustrating me now lol.



I read that refresh rates often cause this, and that xrandr can help me, but I am new to linux and don't exactly know where to start. If anyone could point me in the right direction I would really appreciate it.



Thanks,
Trevor
