Can't make streaming video full screen

[onlycopunk]

So I've been having this problem ever since I got my laptop, which is in sig. I have all the updated drivers and everything, my computer is all up to date. BUT I can't make streaming videos go to fullscreen, like youtube videos and such. It just give me a white and gray screen. I can still hear the sound just no video. Has anyone else run into a problem like this before?

Try right clicking on the video, go to Options and isable Hardware acceleration. If this doesnt help, update your graphic-drivers.
