Colored lines on monitor
So I got a new lcd monitor for christmas. A Samsung 731B. And sometimes it gets either a blue or yellow line going vertically from top to bottom about 4 inches from the left side. It just randomly appears sometimes and I have no idea why or how to get rid of it. I tried restarting and unconnecting/reconnecting monitor to comp. I also took a screenshot and pasted in paint to see if it was the comp or the monitor and it didn't show up so I guess it's the monitor. Any ideas what's wrong/how to fix it?
