Is anyone connecting the 8500 to PCs? I connect my 55 8500 to my HTPC, when setting to Movie Mode, I can see obvious lag on the TV, the mouse moving track is very jerky, and when playing the TV shows I recorded, it has a lip sync problem. When I turned the Game Mode On, the lag is gone, the audio is all sync. But it locks the picture to Standard Mode. And when I set the refresh rate to 60Hz, clicks the info button, it shows 1920x1080i, switches to 24Hz, shows 1920x1080. It means when at 60Hz, I can only get 1080i, not 1080p. Anyone experience this?
