Just recently my Asus monitor has been showing scan lines on left side of the screen but it's only visible when I the screen is black lets say when I boot up my desktop (from the bios screen) I can see it or when I'm viewing a image or video that's not 16x9 I can see the scan lines on the black borders also, although after a several minutes it stops showing these scan lines. It's strange. Is something wrong with my monitor?

First thing I would check or change with a known good one is the cable between the monitor and desktop.

Second thing I would check or change with a known good one is the monitor.


If no good results come from that than it may be leaky capacitors on the graphics card or on the monitor.

Another possibility is a failing power supply.

If a process of elimination confirms that the problem is in the monitor itself, and the effect only appears on one side of the screen, it can be a poor contact in a connector on the LVDS cable that runs from the input PCB to the LCD panel inside the monitor. That can generally be repaired OK, but involves opening up the unit. On the other hand, there could be a problem within the LCD panel itself, which wouldn't be a feasible repair. As Toolman has said, odd symptoms can also be caused by bad electrolytic capacitors, although it would be unusual for such to affect only one side of the screen.
