I have an hd70 and my screen is 108 diag right now I am having issues with the top and bottom of the screen getting cut off during sporting events.My throw space is not the issue so any help on how to fix this would be great.A good example is you cant see the score during a basketball game

Sounds like you are using overscan. Try setting the overscan back to 0.

just looked my overscan is on zero any other ideas?

Your display source has a zoom mode. My Dish ViP622 has a zoom mode that would do the same thing on my PJ.
