Why is the laptop display not working but an external monitor is working? The system prompt me to restart the system. But when I restart, it booted but the display did not show anything. I noticed the keyboard did light up to red then changed to wave color pattern that why I know that the windows boot up. I connected an external monitor and it is working.


I tried to check the display by going to display settings then click detect and it says didn't detect another display.

I cannot even access the bios because the laptop display itself is not working. The external display only works after the windows has been loaded.


Please help. The unit is Acer Nitro 5 AN515-55-56R2
