I have had some issues with my AOC monitor. It will be working fine then it will go to sleep after it hasn't been used and when I go to turn it back on, it says no signal. I unplugged the power cord and plugged it back in, then I unplugged the cord to the computer and plugged it back in. The first time this happened, unplugging from the computer seemed to do the trick. The second time, unplugging the power cord did the trick. This past time nothing would work. I had an extension on the cord to the computer and took that off and just plugged the monitor to the computer and it turned on after a while! i just don't want this to happen again. I'm looking for monitor drivers, but is that what it is? I have a two year old Lenovo computer. Everything is virus protected with Webroot and I have an updated Windows 10.
