So my laptop has this line or bar the runs vertically along the left edge of the screen. This seems to appear even on the bios menu. However i did connect my laptop to an external monitor and the monitor shows the entire screen perfectly. Ive tried adjust the screen resolutions and updating drivers but nothing seems to work. I also re-seated my lcd display's cable but that didnt work as well. I believe this is a hardware issue. Would replacing my lcd display fix the problem?
