DO NOT BUY ACER MONITORS at least the one with GSync capable, I bought a xb321hk for $1000.00 and got the famous artifacting and screen blanking issue.
Below link for Acer's community forum regarding this issue

I have reached the END of Acers customer service line, They only offered me $400 refund LOL. After 5 returns, 3 different xb321hk monitors, I have worked with Corporate Customer service and "Elite" technical support and wasted 3-4 months for $400.00 refund.... Unbelievable. I will continue to post my personal experience on websites and I'll update my Youtube video warning people NOT to buy ACER?,
