For completeness, I have run the BubbleUniverse on this HDMI version, as well as the others and get the following results:-
2040  VGA  @ 378MHz bubble runs at 286mS per frame
2350A VGA  @ 378MHz bubble runs at 163mS per frame
2350A HDMI @ 315MHz bubble runs at 191mS per frame
For VGA approx. a 1.75 times speed up, over 2040 VGA. :-)
For HDMI approx. a 1.5 times speed up, over 2040 VGA, only limited by the fact that the core frequency is 315Mhz (HDMI clock requirement) as opposed to 378Mhz for VGA.
Not too shabby. I'll have to increase the number of points it plots to slow it down again ;-)
Otherwise everything I have so far tested is working fine on the PicoMiteHDMI, display quality looks good stable & sharp & full screen. :-)

Regards Kevin.
