When I connect my laptop to my TV via the HDMI adapter, full screen video is slightly stuttery. It'll play smooth then every 3 secs there'll be a slight stutter, which is far more severe in fast moving scenes. If I use my laptop display, everything is fine. I turned down the resolution of the TV from 1080p to 720p, and it helped a little, or at least it appeared so. Happens on all resolution of video.
