The upcoming beta release of the CFULLHDMA has HDMI Auto Sync.

This means following: if you have a TV supporting EDID you see the available resolutions of your TV. When playing video the CFULLHDMA will detect what is the frame rate and will adjust the screen resolution accordingly.

In above image you see the resolution at 60Hz. We start a movie with 24Hz and than we get the folowing resolution seen on the TV

(you will see the loading icon, the screen will adjust, loading icon will disappear, than re-appear and the TV will show th 24hz)

As seen in the image below
