If you have more than that, rolling may occur on a TV because of the overscan. I can not recall how many scan lines each line of graphics takes, but I think each line of gr.7 is 2 scan lines, and each line of gr.0 is 8 scan lines. Another problem that could cause the rolling on the TV is that if the screen data crosses a 4 K boundry, weird things happen.
