Hi everyone. I just picked up a Late 2012 Mac Mini and put 16GB of RAM and an SSD in it. I already had a 144Hz MSI G27C monitor that I use with my Alienware laptop, which runs great over HDMI 2.1 at 144Hz. Using that same cable, and a 4K/3D mini-DisplayPort to HDMI adapter, I was hoping to run 144Hz on my Mac Mini. I am still seeing only options for 60Hz. I have previously used 144Hz on a Windows-based laptop with Intel HD4000 graphics over HDMI. I was reading that the HDMI port on the Mac Mini won't be able to run 144Hz, so I went with the adapter. I've tried everything, including unlocking the pixel clock and using SwitchResX to make a custom resolution. While this made a 144Hz and 120Hz option available under System Preferences > Displays, the mouse movement is clearly sluggish as if it is still running in 60Hz. I've went to the website https://www.testufo.com/ to test the refresh rate, and it did report 144Hz, but it definitely does not feel like 144Hz. I was hoping to have that seamless mouse movement with no "stuttering", just that beautiful 144Hz effect. I do not intend to do any gaming, I just wanted to take advantage of the "smoothness" as it's going to be my development machine. Has anyone successfully been able to do this? Is Apple mouse input just that jittery on HD4000? On my Macbook Air 2015 with HD6000, the mouse movement was very fluid. Any help is appreciated. UPDATE: I've tried the Patch EDID script to force RGB mode, wasn't sure if it was being read as a television or not, but figured it was worth a try. No luck. I noticed in SwitchResX it offers me 75Hz in 720p mode. I'm curious, do I need a "Thunderbolt 2 Compatible" Mini DisplayPort cable? There is one on Amazon from Cable Matters that claims it's TB2 compatible, and figured it might be worth a shot. Any thoughts?
