Switched monitors and now video is jerky

i have been using two monitors—720p 19inch and 1080p 24 inch. Today I switched the 24 inch for a larger 1080p. Now the video will play for a second and pause for a half second over and over and over. This is true whether from youtube or a video on my harddrive. I’m at a loss.
