Hey all, just wanted to chronicle my story so that this will help people down the line. Just purchased a refurbished 2018 i7/8/512 (w/ more ram on the way). Upon plugging it in to my monitors, the computer kept crashing and rebooting which was absolutely infuriating. I am using two Thinkvision P24h-10 (1440p) displays which I just recently purchased and worked just fine on my 2012 Mac mini (HDMI>HDMI) and (Mini Display Port > Full size Display Port). I plugged in the new mini using a (HDMI>HDMI) cable and a (USB-C > USB-C) but the machine constantly crashed with the only peripherals connected (apple usb keyboard, usb mouse). The USB-C cable connected monitor did not even turn on, so I tried three different USB-C cables (Anker, Apple one from my MacBook 12" Retina, generic). I then realized the Thinkvision monitors did not like my cables as my MacBook could not trigger a monitor with any of the aforementioned cables either. After reading through Lenovo forums and Apple help forums I realized that the displays might be the culprit so I ran to Best Buy at 8:50pm and bought two Apple branded Thunderbolt cables. Everything is now peachy, 12 hours later. I will comment if anything changes.
TLDR; Certain Monitor cables and Certain Monitors combos with new 2018 Mac mini will cause boot loops, random restarts, lock ups. I used two Apple Thunderbolt cables and it resolved my problems.
