I have an ASUS ROG laptop and have recently bought a VGA cable to connect it to a TV monitor. When I disconnected it today from the monitor, and went and turned it on without the monitor it does not turn on. I normally use the Extend function with Control + P. And it seems it won't go back into the normal display setting. How do I reset the display settings or something like that?
It will not go past the black screen. I got home and I hooked it up, and it didn't start up. I need a reply as soon as possible, as I need it for homework.
It could be a loose video cable that is preventing you from receiving video signal on your laptop display. If you possess knowledge of the laptop hardware, you could open the laptop and see if the cable is ok or the backlight tube is working. If you don't, then you must bring your laptop to a technician to make the tests of the LCD cable or the LCD inverter because they might get damaged.
