Question Laptop Screen Broken when screen is not extended,

[charxz02]

My laptop ROG Strix G531GT_G531GT is connected to a smart tv for a while now. I had my screen replaced because it has a line in the middle of the screen, all well and good, connecting it again to my tv as a second monitor, I have not noticed anything wrong until I got a new system removing the HDMI connect of the laptop and the tv my laptop screen look like it broken, attaching the Tv to it again fix it, looking in to it I notice the screen break when its being duplicated or when on "Show only 1"(laptop Screen is the main monitor). i want to give this laptop to my friend but she does not have a second monitor to ignore the problem, anyone know that problem I'm Having.

reinstall the gpu drivers of both graphics chips from the asus homepage
while the external monitor is not attached, unplugged hdmi from the laptop's side, press windows + p and hit enter, wait a view seconds
eventually repeat this two or three times
