I am not a specialist, but this should not be a problem.
There basically is a big difference between the refresh rate of the TV and the framerate of the show.
TV is usually broadcasting at 60hz (60 images per second), but your screen is refreshing (i.e. dispaying) 600 images per second. the TV will therefore display each images 10 times. There is therefore no impact for you.
The only question I have is for blue ray played at 24p (24 images per second, which is the standard way of filming for movies): Will this receiver work with sources at 24p?
