Gamma Correction Problem On FullScreen Mode

Playing examples on standalone fullscreen window.
It does not respect gamma correction settings of my graphic card driver.
It respects on windowed mode but after diving fullscreen everthing becomes much darker.
I cant provide a screenshot, somehow everything seems fine on screenshots but there is a huge difference.
I have GeForce 870M with Intel HD 4000 Optimus.
The gamma correction settings stands on Intel graphic card driver side.
Unfortunately there are no settings in NVIDIA Control Panel for Gamma Correction.
All 2D related settings stands on Intel side with Optimus.
I have played around other DirectX 11 games to check but didnt come to issue like that.
What is your suggestions to get over it ?
Thanks and regards…

Summary: Everything becomes darker in fullscreen mode.
