Great monitor, I bought this monitor to replace my VA monitor which suffered from extreme black smearing and ghosting. Heard that IPS panels are much better when come to the ghosting problem, but there are only a few options for an IPS panel ultrawide 1440p in $300-$400 (AOC, MSI). The MSI one is 40 inch which is way too big for my desk and only run at 155hz. The AOC only run at 144hz. I really wanted this monitor because it was the right size and run at 180hz but $700 is out my price range. First, I decided to give the AOC a try as Amazon had a "Used - Very Good Condition" for $225. It arrived with 4 cracks on the screen. I returned it immediately. I read on reddit that used items from Amazon warehouse is really a gamble. I looked at the listing for this monitor again and saw a "Used - Acceptable" with no descriptions what so ever for $333. Less than half of the original price and since you can always return and get your money back within 30 days. I gave it another try with amazon warehouse used items. This time I got practically a new monitor. Immediately i plugged in and ran all the monitor test, no dead pixel, no bleeding, no uniformity problem. So I thought okay, there must be some cosmetic damages or something....So I looked hard and....nothing. I was so surprise. "Acceptable" is suppose to be worse than "Very Good" condition. So I am more than please with what i got. On to the monitor itself. I don't really know what to say other than that it is a great. It is a huge improvement from my VA monitor. No more black smearing, but still just a little bit of ghosting when running the UFO test...but you have to look hard to notice it. Overdrive setting on "Normal" is the best, setting it to "Extreme" and you will get overshoot. I learned that it run 144hz at stock. The advertised 180hz is an overclock setting. Some people say running your monitor at overclock setting will reduce its lifespan and some people say it doesn't. So it is a mix bag. Speaker on these are meh, but I got my own speaker and headset. The monitor stand on these are great. Very study and well built but i wanted to VESA mount it. And unlike other ACER monitors where there is a button to release the stand from the monitor, I was dumbfounded when come this monitor. I had no idea how to do it and no instruction in the manual either. Had to look up online for the instruction for another Acer monitor with the same stand (Acer predator x34). You had to force pry open the back plate with a flat head screw driver first to expose the four screws that hold stand in place. One thing to know is that IPS is not that great with display deep dark black color. That is the one thing that VA panel is great at. Black color on this panel appear like more of a dark grey, but this appearance of the dark grey for black only really noticeable in really dark room with no lighting. Another thing to mention is that USB hub on this monitor will use the USB C connection by default. I tried to use it with a USB B connection but it didn't work at first. I thought my cable was bad, but it turned that you need to manually select the connection in the monitor system menu setting. Overall, I really like this monitor.
