Fluctuation on dell led monitor

[sanny16]

I have Dell 21.5 inch LED Panel Monitor-S2240L (Black) and its only 6 months old. I have noticed slight fluctuation or flickering effect only on a specific portion on top right hand side of the screen. What could be the cause of such flickering? The content on the screen does not flickering but the monitor screen layer does. How could i fix it? Did anyone else suffer with this problem?

Electromagnetic disturbance ?

Have you tried changing location of your Monitor ?

Have you overclocked the graphic card? Also, can you post a video showing the flicker?

The flickering occurs for sometimes and then it goes away. Its fine now.. If the problem persists then i will post the image/video of it.
