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.

Well my monitor just died no picture no power nothing its just dead. It died on me right in the middle of a YouTube video (which is better then it dying during an update) I had force shut down my desktop. I don't trust Asus monitors anymore the first Asus monitor (back in 2013/2014) I had was DOA and now this one just died on me. :(

That's disappointing, although it may give strength to the possibility it has bad capacitors, which is not a difficult fix, as long as it's only the capacitors at fault. I've never used Asus monitors, so I can't comment on their general reliability.

I bought a new monitor an Acer and it seems to be working fine for now.
