Do you have the owner's manual? Since there a gazillion Asus laptops, only you have access to that information.
On a general note, is there a hot key or graphics configuration that activates the HDMI port on the laptop?
I have an Asus laptop with Windows 7 and am having problems connecting it to my Samsung HDTV. When I connect the HDMI cable from the laptop to the tv, the tv says no signal detected. I tried a few things I found on internet searches but nothing produced results. Any help would be appreciated.
