We have designed a board with an oled display which supports 680X480 an 800X600 RGB resolutions. The 640X480 works perfectly with ADV7391 525p ED mode.
I haven't seen any 800X600 mode on the ADV739X datasheet (REV E). But on previous releases (REV B), was mentioned a non standard resolution is available.
The question is, can I trick the DAC to output 800X600@60Hz?
Thank you for your support.
