Amongst other things, the STE has top/bottom border timings 4 cycles 
earlier. So a 60/50 Hz made to work just at the limit on STF will be 
considered good but might be rejected on STE just for 4 cycles :(

Even on STF, relying on a 60/50 happening right at the limit is a bad 
idea, because there can always be a slight jitter of 0-8 cycles when you 
use the HBL int to remove the top border with a "stop 2100" for example 
(even if all others int are stopped/masked).

So, it's quite likely this menu doesn't work on real STE.
