I found this when searching for a way to generate an HDMI signal with a microcontroller (as in Atmel AVR).
You know, how we've seen done with VGA.
But apparently, you can't bitbang out a HDMI signal with anything less than an FPGA because the bitrate is just too high. And even this article mentions that for higher resolutions, you may need to misuse some lines intended for interfacing with DDR...
