A:AnswerYes it is g-sync compatible as well. I was thrown off by the box as well but I was able to go into the nvidia control panel and enable g-sync. I’m thinking it’s one of the monitors that became g-sync compatible after it was released.
A:AnswerThis would be the range for Gsync/freesync. It matches your refresh rate with your fps, this is to eliminate screen tearing. As I understand it you can turn this off and have a set 144hz
A:AnswerYeah theres no issue here are two companies that acer recommend to me. Vivo and Humancentric I also made sure to ask if doing this will hurt the monitor in any way he said no they just weren't designed to be mounted. When you buy the adapter just make sure it says its compatible and watch a vid or two on installs.
