I tried to turn on the "night mode", I can solve this problem.
Under the "night mode", I can see movies normally.
When I turn off the "night mode", I can't see movies.
It is strange for me, but I can use this by night mode all the time.
Thank you.

When I try to play some movie in a website, I can't watch actual movie in the screen by Lenovo ideapad flex 3i.
The screen shows only full white.(Audio is OK.)
I can watch the movie in the chrome web browser.
I want to fix this problem soon!
