Win notebook 2 screen?

My Leptop has a defective monitor so I would always have that image on a 2 monitor. Have the leptop then set back so everything new and now I can't show that picture. Can you help me?

2 connect the monitor and go into the BIOS, there you may be able to adjust.

Or on the keyboard there's a switch.

Or open notebook and disconnect internal monitor then he automatically takes the external monitor because he does not recognize an internal monitor.

Can you sometimes write your exact type designation of the laptop.

But I see no picture on the monitor.

Why that?

Type: Then maybe I can send you a helpful link on how to disconnect the internal monitor.

…

In the BIOS if you have already turned on the external monitor when you start the image is usually from the boot and then synonymous from the BIOS on both monitors.

…

Or see if you have a shift key on the keyboard.

…

Again, it is helpful to know which notebook you have.

Of course, you do not have to say which notebook you have.

No no that is not a problem. An Asus Aspire E1-570G

The Umschaltraste I have also pressed but there was no picture displayed and how do I get into the BIOS?

Turn on the notebook and press the F2 or F12 key very often and quickly.

It can also be that you have to hold the FN key.

Does not work somehow: /

Try it often. Is sometimes stupid to achieve.

If nothing helps then diplay can abkönnen.

See about 4min22sec. Where the plug is removed.

Have a look again. You have to hold down the FN key and then very often press the F2 key.

Or try a USB keyboard if you have one.

If nothing helps then diplay can abkönnen.

Sorry, shall mean: If nothing helps then disconnect display.
