Dell Inspiron 15R SE 7520, blurred display after upgrading to windows 10

Dear Dell Forum,
Recently, I have upgraded from my windows 8.1 to windows 10. After I upgraded, I found blurred displays issue.
I have done the following things to resolve my issue.

1. Updated all the latest drivers.
2. Changed screen resolution to and fro
3. Updated AMD Radeon HD 7700M series and Intel® HD Graphics 4000

For web browsers and File Explorers, I can see very clear display without any issue.
But for installed software’s (for example Skype and some other installed applications), I have the blurred display problems.
If I open “Device Manager”, I have the same issue. If I try to install any software, the pop-up box also blurry display.
I think because of this issue, system start up takes longer time.
I am researching this issue since more than a month. Please, can someone help me how to resolve this issue?

thanks in advance..!
