I have a white vertical line on my laptop and it is present the moment I boot. Going to BIOS did not get rid of it. Pressing along LCD bezel did not get rid of it. I did a screen mirror to my TV and there was no vertical line on the TV. I then re-installed Windows 10 and updated my drivers. Same white vertical line as soon as I boot. I then opened up the laptop and detached and re-attached the LCD cable connector to the motherboard and LCD screen. Still the same. Finally, I bought a replacement LCD cable and replaced the original one. Still the same. At this point, I am assuming that the vertical white line is a hardware issue with the LCD screen. Would you agree? Is there something else that I should try before getting the replacement screen? By the way, my system is an HP Envy 17t - k100.
