I have a Mac mini desktop. I have a 23" monitor. I want to get a 27" monitor. The Best Buy website has 27" monitors but they have free sync. If I understand free sync, the monitor requires an AMD video card in order to work. My mini has an Intel HD Graphics 4000 1536 MB video chip. I assume that means that any monitors that have free sync won't work on my Mac mini. Am I right?
