So last night I had a few power outages due to a storm, and after one of them I decided to go to bed. After waking up and turning on my computer I noticed only my main monitor was working. My left monitor however had a green light around the power button. So I switched the cords between the two monitors, 2nd still doesn't work, so its not the cords. Then I grabbed a whole other monitor and it is also doing the same thing, so its not the monitors.
Anyone have any solutions?
Thanks a lot!
