I got a Acer monitor a couple months back for my computer, I also got it because it has two HDMI ports, so I could connect an xbox or something when I got it. Finally got one and it won't work.
I tried lots of troubleshooting. The monitor model is: "Acer S230HLAbii".
Start my troubleshooting at at the basics though, just so I can be sure I didn't miss anything.
