Screen turns black for few seconds after starting a video

Hi, I'm having problems with black screen which appears for few seconds after I play a video. It only lasts for 2-3 secs and then it's all normal. After going normal it always shows the HDMI sign just like between switching the modes on monitor. Problem appears with my video files on desktop and with those on YouTube of Facebook as well. So if I want to scroll the page down I have to wait on every video that is on the page.

Specs:
- win 10 education 64 bit
- GTX980
- i7 4790k

I should also add that on Win 7 with the same spec I did not happen.

Do you have any ideas?

The latest NVIDIA driver causes these problems. Replacing it with an older version should solve it.

It's happening since I upgraded to Win 10. And I had many different NVIDIA drivers installed since then.

I did some searching and this should solve it:
NVIDIA control panel > Adjust Desktop Color settings > "Content Type Reported to the Display" > change from "Auto-select (recommended)" to "Desktop programs"

Yep, that's it. Now it works perfectly. Thank you so much!
