I have an asus laptop that took a tumble off my bed and the screen cracked. I hooked it up to an external monitor and it connected right away. I had been using it like that for a couple months when all of a sudden, when I booted up my laptop, it wouldn't connect to the monitor. I've tried pressing fn+f8 and tried closing the screen right after booting it up. I'm strapped for cash at the moment so I cant get the screen repaired at the moment. I have unplugged the video cable and plugged it back in, I've switched them. When I take it out, the external monitor says "Check Video Cable." but when I hook it all up, it says monitor going to sleep and then goes black screen. I think I've read through almost every thread about this, but nothing works. Can anyone give me any other ideas?
