If you're watching the Australian Open coverage, the score box and ESPN2 logos are supposed to be pushed out to the edges like that.
If you are watching in HD and the score box is partially cut off, your TV needs to be set to eliminate overscan. How this is done depends on your TV model, but most flatscreen TVs allow for this. You should do this anyway, because it adds a tiny bit of extra sharpness to the picture.
For whatever reason, ESPN is not respecting the typical 15% overscan zone with its digital graphics for the Australian Open.
