I assume you are using a VGA to component cable like this
Keep in mind that you HDTV needs to be able to transcode video signals from VGA to/from Component
I recently purchased a VGA to component cable to connect my laptop to my HDTV. After connecting, I tried adjusting the resolution and toggled between view modes, but I can't get anything to show up on the TV. I have an Inspiron 1720 laptop. Anyone have any ideas as to why there is no picture on the TV? Thanks.
