Have used my HP 2000 laptop many times to connect to a big screen TV using the VGA output jack and hook it to the VGA input of my big screen. Now, for some reason, there is no video output to the big screen, I have tried 3 different cords (VGA to VGA) and get nothing on two, and on the third I get a video transfer but it blinks off and on both on the monitor of the laptop and my big screen with only about 1/2 of a picture showing on both. When it did this, I tried repositioning the output jack on the computer output and it changed the picture somewhat, but could never get it to work. Any ideas???
