Hi I've changed my outport settings on my laptop now it's a blank screen I don't know how to get it back plz help

Jan 28, 2016
I tried to connect my Acer aspire e15 to my smart TVs nothing showed up so I tried to project ,duplicate it , but now my laptops screen go black and once I turn my laptop off (just by holding the power button till it turns off)The Acer logo showers up and the loading but the screen go black after and now I'm stuck how do I get it back so I am able to see what on my screen

Please do try these troubleshooting steps that may help in solving the issue.
- Start by doing a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then boot it back and see if it will load normally.
- Next is to again connect the external monitor to your laptop and see if you'll get any display from it, if the same problem will persist press the shortcut key on your keyboard to enable/disable projector mode.
- If these doesn't work try loading in Safe Mode to disable the Duplicate Mode.
