1. Connect the external monitor to the laptop's video port, power up the external monitor first and the laptop. The video information will automatically switch to the external monitor.
2. If you power up the laptop first then you can switch the video output to the external monitor by pressing the Fn key and one of the Function keys, depending upon your make and model laptop.

My HP Pavillion M70 monitor is saying "video cable connected?" when I try to use the monitor. I am trying to output my laptop to the monitor because my laptop screen is wearing out, but I cannot get it to work correctly. I set the monitor output options to dual output, but the monitor still says the same thing.


go into the BIOS settings and tell it to use the LCD/Monitor as a display.

or

press fn key+(F5 or F7 or F8) 1x or 2x or 3x.....

Fn key combination. The Fn key is located at the lower left of the keyboard, normally between the CTRL and the ALT key. Toshiba uses Fn-F5 to toggle between the laptop LCD and an external display. IBM or Lenovo uses FN-F7, Acer varies with the model, using Fn-F5, Fn-F3, Fn-F8, Sony Fn-F7, Dell Fn-F8, HP or Compaq, Fn-F4. There are variations with the age of the laptop and not all manufacturers have standardized on a key combo across the whole range, but you can usually figure it out from the little graphics on the function keys that line the top of the keyboard.
