I currently use a 2018 Mac Mini with an LG 27" 4K display. Since I put these two together, there has been an annoying lag before the display lights up. I am going to buy another desktop Mac this Fall. I would prefer an iMac 27 but that doesn't seem to be in the 2022 pipeline. So, a Mac Mini with a 27" display that pairs with it seamlessly is what I hope to find. Any suggestions are appreciated.
