A line of dead pixels generally occurs due to a manufacturing defect or physical damage that disrupts the electrical charge needed to operate those pixels. To address this, first, try running a pixel-fixing software which can sometimes stimulate the pixels back to life. If this does not work, checking the warranty might be your next best step, as many manufacturers cover dead pixels under their warranty policies.
