It's the TV itself with all of it's sharpness and signal processing. It IS the Soap Opera effect, since those are shot at 60fps if I'm remembering correctly. Hate that.

All that processing is ok for tv shows, but if you try to hook up as a monitor your mouse with seem like it's freaked out on bath salts.

Turn all that processing stuff off in the TV settings and it'll start to look normal again.
