I have a 19" samsung monitor and a LCD TV. Firstly, I connect my pc to LCD TV with vga cable. Then I unpluged cabble and connect it to my monitor. But now I can't see anything on the monitor. Do anyone know why had it gone?
The resolution or frequency of your LCD TV may be set too high (or low) for your regular screen.
If that doesn't help, rebooting to safe mode and selecting the Plug and play monitor driver for your screen may help.
