AOC AGON 23.8" 1440p 165Hz G-SYNC Monitor

I have had it for a couple weeks now and it’s working pretty well. I bought this monitor to replace a 46inch Samsung LED TV that I used for a computer monitor and gaming. I definitely something not so big (I had it on a desk, if it was mounted and a significant distance from my face it would have been no biggie). The GSync works pretty well. I am running a 980Ti so I can not compare it to the 1080Ti or the 2060/70/80 cards. The screen has a slight yellow hue out of the box that I was able to resolve via the display settings. The vendor website has an online manual that you can download that’s pretty easy to find. I was also able to download the latest drivers. However, I cannot at this time get the USB ports to work (I don’t know if this is driver related or an issue with the refurbished model). Overall, for the money I saved, so far so good. Hopefully I can figure out what’s going on with the ports.
