There was one red vertical thin line at the left of my Acer 15" LCD monitor. now there are two red vertical line at each ends of the monitor.How it can be removed?
Seems like the issue is with the LCD monitor. Try to test if the same issue is seen to another monitor when connected to your computer. If it does not show up on another monitor, it would be specific to your Aces LCD. You can then try restoring/resetting it to factory defaults by navigating through the OSD or menu buttons,
On the other hand, if it also shows up on another monitor, it will then point to the video controller/card or to the cable being used. You can then using other video cables, try using other video card/connectors if any and applicable to your computer. Updating video drivers and checking your video settings in this case may also help.
Good luck and hope the info will be useful
The LCD panel is going bad. Nothing is wrong with your computer. If the screen is not under warranty, then I would suggest replacing it with a new one
I think this is most likely a monitor problem. Can you try a different monitor of computer to the monitor? That would help pinpoint the problem. Is it under warranty?
