So I just hooked a 48" tv to my gpu and everything is working great except for youtube videos. Everytime I try to enlarge the videos to fullscreen my pc or screen goes black for a second, then enlarges to the point where the edges of the video are off screen. I've tried different resolutions, on youtube and native, but still the same thing. Any ideas?

ps-Videos worked fine on my pc monitor...24" Samsung.
