That's a tough one man. That's what im experiencing on my monitor is this screen tear or motion tear. I think with G-sync that will solve it. If someone with more experience could answer that for u be great. I've only ever bought two monitors in my life, and only recently have gained huge interest in higher res displays and the tech behind amazing ones. That acer looks great, i would look up reviews, and just research youtube and google and i'm sure you won't make the mistake i made. Good luck, and have fun gaming at 4k.
