I fixed my mom's ASUS computer recently by re-attaching the video cable to the LCD Screen. This required that I take off the plastic LCD bezel and remove 6 screws on her model to get to back end of the LCD screen in its raw form..
This fixed the issue for a couple of months and then red streaks appeared again. After making sure the LCD Cable was firmly attached, I figure out the LCD was warped. Her fix was to push forward the two upper sides of the LCD screen toward her. This fixed it for her session on the laptop. Every time after closing the lid and re-opening it, she had to do that. Her laptop is a AMD dedicated GPU card type that does 1080p. I gave her mine and now get the excuse to get another gaming laptop.
While I am not a ASUS technician, I have worked on Laptops as a benchtech for a decade. So, I am comfortable doing what I did.
