Global Draw performance

[350D]

Developers, i have a question/idea for you.
What the maximum fps for global draw available? If you guys can scan full hd picture from sensor for RAW recording - how fast you can output this data on the screen? Is this possible? (theoretically, maybe with some limitations like less fps, less color depth etc.) or maybe you can use part of this data just to fill the missing parts of the image outside of the gray frame in live view to cover full image? Just curious about to get clean picture on hdmi out.

Right now i'm using ML to hide everything on the screen (focus frame, all info, etc) and then cropping black parts of the frame in my capture software and rescaling it to full hd.

It sounds like your real question is how to get clean hdmi out of the camera. "Global Draw" is not the answer here. You might also want to specify which camera (as some cameras can already do this).

I known the answer for question about clean HDMI on camera other than 5DM3 My question is more about idea.

I'm on 6D right now.
So, any thoughts about this idea?
