I have a laptop that screen is broken, been connecting it to external monitor and was fine, I was trying to fix a Java error and reinstall graphics Driver. All was fine it reverted back to stock Driver and was downloading the new updated Driver when laptop died. Now I start it backup and I can't connect to external monitor or my HDTV which I did before also. None of the known keystrokes to project it to another monitor is working I normally don't need help with tech but this one I'm stumped?!?! HELP!!!!
