laptop screen output changed to Monitor, now cant turn back

Hi.
Basically i wanted to watch a movie running on my laptop but connected to TV thru PC-in(the vga blue connector).
During boot up the tv displyed Windows logo and loading but then after it went "No signal" and laptop monitor turned on.
After that i righ clicked desktop on laptop and saw this option "Output"(its in russian so not sure wats its gonna be in english translation), and selected "Monitor", the tv instead of saying "no signal" started displaying "Unsupported signal", and the laptop screen shut down at the same time. So now i cant go back to normal laptop screen since it thinks that im using my tv screen, but i cant see anything therefore i cant change it back.
Tried to restart, ctrl-alt-del, and other stuff but didnt help.
Also tried my PC monitor but same thing with unsupported signal.
So yeah, im stuck, how can I fix it back.

You should have a FN plus display keys to toggle through your display devices.

i tried pressing and holding "Fn" but didnt help

Fn F5(toggles int./ext./both)- Toshiba

Other brands

you'll need to press FN and hold aswell as pressing f5 or f6 depending on your laptop however it will have like a screen logo on it.

otherwise its easier to just use your graphic application. go to the desktop and right click then if nvidia is your graphic use the nvidia control panel, then go to set multiple screens and there select (clone)

if ATI same, but go to TV settings
if Intel you'll have to right click on desktop, go to proprtities, then go to display at the end, then advanced then find intel utility.

Yeah, thx guys, tho for some unexplainable reason when I turned my laptop today it was fine.

A complete shutdown, wait a minute or longer , then boot up has fixed many a weird thing for me.
