Yes, I also made similar guess.

I am surprise why TI is not disclosing these information.
For DM355 : spruf73a.pdf and for DM6446 : sprue66d.pdf they only show
boot settings for PAL.
I think they should tell the procedure to calculate buffers for video
and osd based upon user resolution. So that user can use it as per their
resolution.

DM6446 and DM355 is having limited memory if we set wrong or more value
for buffers it is just wastage for memory.

hmm, what is the idea behind 10 buffers ?

I think you miss this question:
Are you able to play DVEVM demos by using VGA LCD ?

Thank you for help,
