My wife has a little Asus Vivobook, and watches videos on it. Today I tried plugging it into the home entertainment system but I couldn't get the picture to show.

Setup is Vivobook -> HDMI -> Onkyo TX-RS508 -> HDMI -> 50" Samsung LCD TV

The PC can tell HDMI is connected, it brings up a model number for the TV. I used Windows-P to try extending and mirroring the desktop. I went into the Intel graphics driver and fiddled around. Nothing helped. I did a search and read a dozen pages, nothing helpful, just one huge page on an intel website with people saying it doesn't work for them.

Anyone have any ideas/tips to try to get it working?
