Vertical stripes on industrial computer monitors are a common problem that may be caused by a variety of reasons. The following are some of the main causes and their corresponding solutions based on the search results:   Cause 1: Influence of humid environment   Cause analysis: A humid environment will have a certain impact on LCD monitors. If the monitor is placed near a humid environment, humid air enters the PC monitor, which may cause the internal circuits of the display to become damp, causing a short circuit or other electrical failure, resulting in vertical stripes on the screen. Solution: In this case, it is recommended to move the monitor to a dry environment and ask a professional maintenance personnel to inspect and repair it. Users can also try to use a dehumidifier or desiccant to reduce the humidity of the environment to prevent similar problems from happening again.   Cause 2: Loose signal source cable   Cause analysis: Vertical stripes appear on the screen due to the loose connection of the VGA cable or HDMI cable connecting the signal source cable of the monitor Solution: It is recommended to try to replace the connection cable or reconnect the VGA cable or HDMI cable to see if the monitor stripes still exist.   Cause 3: Display screen failure   Cause analysis: If the monitor still displays dark vertical stripes and the position remains unchanged after the signal line is loosened, it may be caused by a display panel failure. This includes display cable failure, screen cable breakage or looseness, etc. Solution: In this case, it is recommended to contact the display after-sales service for troubleshooting. If only the internal screen cable is loose, the problem may be solved after reconnection; if the display is damaged, the entire LCD Panel needs to be replaced.   Summary   There may be many reasons for vertical stripes on LCD monitors, including the influence of humid environment, loose signal cable, display screen failure, etc. For different reasons, corresponding solutions can be taken, such as adjusting the placement environment of the monitor, eliminating interference sources, replacing damaged display screens, etc. If the problem is more complicated or cannot be solved by yourself, it is recommended to contact professional maintenance personnel or LCD monitor after-sales service for processing.
