Why are there vertical lines on a computer monitor? (15 views)

Vertical lines on a computer monitor may indicate a loose cable, a damaged display panel, a graphics card issue, or a faulty connection. Check whether the lines appear after reconnecting the cables or using another display. If they persist across different devices, the monitor itself may need inspection or repair.
