UPDATE: I ordered a replacement because there's a piece of metal sticking in front of one of the HDMI ports. Also, I looked up the manual online, and there was supposed to be a Displayport included. The light bleeding went away though, and everything else about this monitor is fantastic for gaming, especially on games like Overwatch. Acer, you did a great job, but the QC and missing cable justified a replacement for me.
Final update: 3/5 because customer support said they'd send me a displayport cable. I opted for replacement instead, and when the second monitor arrived, I saw that it also didn't have a displayport cable. Why would Acer sell a 240hz monitor and not include the cable to achieve 240hz? All my other gaming monitors came with the necessary cables to get it to its advertised speeds. The online manual also said a displayport cable should be included, but Acer's online support said that it was "optional," but all the other included cables, like HDMI and USB, were also labelled as "optional."
Gaming wise, this beats the MSI 240hz 0.5ms G-Sync monitor because it doesn't trail as much when the overdrive setting is set to extreme, but again, this doesn't come with the necessary cable to get to 240hz right out of the box! That's another 10-20 dollars needed to get the most out of this monitor.
