Just started happening yesterday. I shut my system down each night, and this morning, I fire my rig back up only to find that my monitor (an Acer AL2216W model) wouldn't display anything, but the green power LED on the monitor's power button kept flashing from green to amber, then back to green over and over again.I tried powering it off, then back on again, and nothing happened. I tried unplugging the monitor from power and back in again, but nothing happened. Then I unplugged the monitor from my video card, then back in, and after a few seconds, my display was back. So now I'm wondering if it's the monitor itself that's going bad, or if my video card is bad. Since power on and off and unplugging from power didn't work, but unplugging/replugging the input did, I'd like to think it was my vid card (and it's under warranty so I can RMA it), but I wanted to find out what you guys thought about the problem. Any advice is very much appreciated!
