Weird HDMI Problem

John1998 · Sep 20, 2014

Hi everybody, I faced a very annoying problem right here. Every time when i plugged out a HDMI cable from my TV, my laptop will pop up a white dotted line and flashing while booting. However, the white line will disappear after i reboot my laptop for many times(about 10-15 times). I felt very annoyed about this problem, I hope i can receive the solution soon. TQ!
*My laptop model is ASUS N550LF

Have you set the laptop to take a external monitor prior to plugging in the HDMI cable

Do you have a monitor hooked up to the laptop via a cable?

Maybe you need to upgrade your graphics card software? most of the time it will help solve some problems like that. Hope it work for your laptop.
