Even just counting the visible pixels, the upgrade position looks
512x256x72 = 9,437,184 dot clock
800x600x50 = 28,800,000 "
800x600x25 = 14,400,000 "
1080x720x30 = 19,440,000 "
1080x720x15 = 9,720,000 "
1080x720x12 = 9,331,200 "
Hmmm, I see the limitation...
It strikes me that 1080P at half intended frame rate, then externally frame
doubling using new hardware on the output would give 1080P/24, /25 or /30,
but... It requires an external frame doubler. That could be as simple as a
pair of FIFOs and a small CPLD though.
I wonder if 12fps would cause people to complain about responsiveness
during online gaming ;)
