What Causes Lines to Appear on the Car's Central Control Screen?
3 Answers
Introduction to the causes of lines appearing on the car's central control screen: Incorrect resolution settings: The display resolution is set incorrectly or there is an issue with the graphics card driver. It is recommended to increase the display resolution and refresh rate as much as possible, and reinstall the graphics card driver. Presence of high-power electrical appliances nearby: There are high-power electrical appliances or magnetic interference near the display. Try relocating the display to a different position or orientation. Poor connection at the interface: There is a poor connection between the display interface and the graphics card interface. Try reconnecting the cables and interfaces, or switch the display interface from VGA to DVI.
I remember once while driving, a vertical line suddenly appeared on the center console screen, which really affected my navigation. I suspect it might be due to screen aging or sun damage, as high temperatures can cause issues with LCD screens. After restarting the car, it sometimes disappears, but the problem frequently recurs, indicating possible loose connections or internal short circuits. I tried checking the cable connections myself to see if they were secure, but without proper tools, it was difficult. This is a pretty common issue, especially when starting the car after parking outdoors in summer. My suggestion is to first try a soft reboot—turn the system off and on again. If that doesn’t help, it’s best not to tamper with it yourself and instead take it to a professional repair shop for diagnosis to prevent a minor issue from turning into a major fault. Also, during regular maintenance, make sure to clean the screen properly and avoid using wet cloths to prevent short circuits.
Lines appearing on the screen are mostly related to the display unit or circuitry in my opinion. It could be a software issue causing data corruption, such as compatibility problems after an update; or hardware issues like damaged screen panels or loose internal wiring connections. Another possible reason might be significant voltage fluctuations in the vehicle affecting power supply. First, try resetting the system by disconnecting the battery for a few minutes and then reconnecting it to see if the lines disappear. During inspection, pay attention to whether there are any cracks or indentations on the screen surface, as this is crucial. If you're not knowledgeable, avoid forcing any operations to prevent further damage. It's recommended to consult a car-savvy friend or visit a professional shop to use diagnostic tools to identify deeper issues, such as motherboard or graphics card failures. For prevention, regularly update the vehicle's software and avoid parking in direct sunlight.
