Symptoms of vertical lines computer monitor may be associated with graphics cards, display cables or display damage. Begin by verifying all cable connections, and switching ports where possible. Visual glitches due to software conflicts can be also resolved by updating the GPU drivers. The other test that can be of use is by connecting another monitor to your PC. When the new monitor is fine, then the existing screen might be damaged internally or have a broken display controller.
