    Windows 8.1 HDMI Video not working


      Hardware: Dell Inspiron 17R
      OS: Windows 8.1 x64


      -connecting to-


      LG 32LS3400



      Couple weeks back (as of 1 November 2014) I was in class doing a render with Cinema 4D, a 3D animation software. The render itself was extremely demanding of PC resources and froze. I tried to abort the render, and got a window I do not recall except I did briefly see "Display." Same night I got home I hooked up my laptop to the LG TV and noticed glitches on the TV, flashing, all until I dropped the refresh rate from 60 hz to 30 hz. I had tried connecting to other TV's and had no issue. As for the LG, It still had minor glitches but the screen stayed on and I continued to figure out what went wrong. Several days ago, I read in a post to delete the display driver and reinstall it.


      Soooooooooooooooooooooooooooooooooooooooooooooooo I did just that.


      NOW, I get no picture on either my LG or other TV's. Or any monitor.


      My laptop does recognize the fact there is a TV. Using Debut Video Capture, the preview shows my main desktop plus the extended desktop.


      So now I've basically ran out of ideas, and the last thing I want to do is completely nuke my laptop and rebuild it for an extended display.


      Anyone know a good fix?
