No display after extending desktop

Hi, I have Windows Vista Home Premium.

I wanted to extend my desktop to my TV, and, after having inserted the cable
between the computer and the TV, I went into display settings, and pressed
extend screen to secondary screen, and everything went black. Both the TV and
the computerscreen, which is an LCD.

Now I can't do anything to get it back. I tried waiting to see, if it would
return to previous state, but it did not. I pulled the TV cable and restarted
the computer, it didn't help. I tried to switch resolution settings after
rebooting in Windows Safety mode, but when I started Windows normally, the
screen was still black.

I have an Nvidia GeForce 8600 GTS graphics card, with 2 display outputs and
a super-video output. I connected the TV cable to the super-video output. I
tried putting the DVI computer screen into the other output, but it didn't
help.

I would like to know, how I can reset the monitor, so I can use my computer
again. And remember, I cannot use my eyes to navigate, since the screen is
black.

Regards

Boot into safe mode and do a system restore back to where you were before
you tried extending your desktop.

Hi

Thanks. It worked. Luckily I had a backup point from 2 days ago. Just weird
behaviour. I tried again with the clone feature, where you show main screen
on both screens, and it went black again, so now I have to restore back to
that point again, but well. At least there's a way back.
