I believe itis possible, but in a much easier way than you think.
@meega
You dont have to run Workbench in SuperHiRes Mode. You can just run it in Hires Interlaced and upscale it somewhat.
The easiest way Ive seen to get HDMI on Amiga is via and Upscale DVD player with S-Video inputs...........My DVD Player upscales my Amiga Output and outputs it to my FLickerFixing Projector via HDMI.........it looks the same as S-video but blurry somewhat because I guess the upscaler expects pixelization and overcompensates.
Therefore HDMI is possible on the Amiga via a simple scandoubler type looking device that attaches to the RGB port and does the Upscaling, yet supports SuperHires interlaced mode as well if someone chose to use that.
Personally I use SuperHiresMode for Text credits and scrolling credits on Video.........looks freakin awesome.
Sometimes getting too technical about things makes it seem impossible. but it is easily achievable (and by that I dont mean that it is easy creating the hardware) I just mean the concept is easy.
The Amiga itself doesnt have to have a native HDMI output, because then it would need modifications and slow down the system...........
