Help. Laptop won't hookup to multiple TVs via HDMI

[greenlightskies]

My ASUS TP550L won't connect to my Samsung TV or my Toshiba TV. It was working fine this morning then I went to school and came back, turned it on and it read "No Signal" continuously on the screen. I've tried multiple techniques to get it going. Turning it off and on again, with/without cable plugged in, reverse cable, multiple hdmi ports, multiple hdmi cables, multiple tvs, updated graphics drivers, Fn+f8 to duplicate project, detect projector in display settings.

Does anyone have any other things I could try out? I'm starting to pull my hair a little here. Thanks

Did by any chance the computer get updates? If so, that could be your problem. You may need to downgrade the drivers.
