Hi,everybody, How to expand a DVI/HDMI output interface for DM355? is it possible? using a DVI transmitter TFP410 to do it on OMAP3 Beagleboard,BUT DM355 support 18bit RGB666 Digital output, and according the TFP410 datasheet, it support only 12Bit Dual-Edge and 24Bit,single-edge input mode. any advices is appreciate, thanks!

You could use the 24 bit single edge mode and only use 18 bits instead of the full 24 bits (i.e. connect the 6 bits of each channel to the MSBs of the 8 bit channel on the TFP ignoring the two LSBs), this would mean you lose some color depth but it would still be functional. I have not seen a DVI/HDMI implementation with the DM355 but it should be possible, even if it means cutting some color depth.
