Hello

I wonder why my laptop does not recognize its LCD screen, ie on Windows, for example, only I get the external display that I have connected.

I put a little situation.
-An external monitor works. Therefore, the integrated graphics card on the motherboard works.
"The bios works (from an external monitor is), so the motherboard can not be broken.

"Possible causes:

LCD-Display. I can not, when broken LCD screens, windows continues to recognize, but not see anything.

LCD-flex cable. It is the number one to be the culprit. Do you think I should use a multimeter to discard?

-Connectors on the motherboard to flex cable. It's hard to be this.
-Connectors of the screen. Idem.

What do you think I should do?

Sorry mi english.

5. click on the display settings, and you should know what to do next.
