ANSI C63.4-2009 requires scrolling H, and FCC is under way to transition from ANSI C63.4-2003 to C63.4-2009. So, I think USA will still go their own way. > I have seen a worst case using H pattern, so I wonder if I can get away with > just testing with the H pattern as it is also in the CISPR 32 table. CISPR 32 says "Video ports shall output signals, and images shall be displayed, corresponding to the highest complexity level listed in Table B.1 that the EUT is capable of generating.", so I think we shouldn't use scrolling H (level 2) when colour bar with moving element (level 4) can be used. Anyway, I think the difference of the display test pattern is relatively small problem. There are more burdensome differences in, for example, EUT setup, test method for 1 GHz and above.
