TI told me that they have a 3rd party LCD option from LogicPD that connects to DC5 on the EVM. http://www.logicpd.com/products/displaykit/LCD-6.4-VGA-10/ $799 http://www.logicpd.com/legacy/support/order/ DaVinci LCD Adapter Board USD$349 The DC5 connector is 25x2 with the following pinout. The DM355 has a VPBE with a DLCD that the spec says can drive an 18-bit TTL output for a typical LCD. I think that when the VPBE is in PRGB mode, the DC5 connector can be wired directly to a typical LCD. For example, VDOUT_Y[7:0] becomes { G[7:5] , R[7:3] }, VDOUT_C[7:0] becomes { G[4:2], B[7:3] } which gives you RGB565. You should check if the davincifb driver supports this mode and what pins need to be mapped to enable RGB666 for 18-bit TTL.
