Lenovo IdeaPad Y560 abnormal gradients

[rihit]

I am using this Lenovo IdeaPad Y560 from last one month and that was running without any issue earlier but from last two days I found that there are some abnormal gradients on the screen. This is more on the edges of the screen. I am not able to understand that how this comes on the screen and what is the solution for this problem. If you are having any idea about this problem that hoe this can be resolved then please let me know that. I will be thankful to all the replies for this.

This is seemed to be problem with the display driver and for that reason 'you are getting this problem. So my suggestion to you is to update the display driver and see if that can solve the issue for you.
