Hi everyone,
I’m experiencing an issue with my PC monitor and would appreciate some advice.
Device: HP Pavilion Gaming Desktop
Operating System: Windows 11 Pro
Monitor: Acer Nitro 24-inch Full HD Monitor
Recently, several red vertical lines started appearing on my screen. The lines are visible all the time, including on the desktop, in applications, and sometimes during startup. They seem to stay in the same position and do not disappear after restarting the computer.
Things I’ve tried:
- Restarting the PC
- Updating the graphics drivers
- Disconnecting and reconnecting the monitor cable
- Using a different HDMI cable
- Changing the screen resolution and refresh rate
The red lines are still present, and I’m not sure whether the issue is caused by the monitor, graphics card, display cable, or a software problem. The PC otherwise appears to be functioning normally.
Has anyone dealt with a similar problem? What usually causes red lines to appear on a PC screen, and are there any troubleshooting steps or repairs I should try before replacing any hardware?
Thanks in advance for your help!
