Having issues with run-dmd. Tried to update the SD card. Followed instructions. When I insert the SD card I hold the 3rd button and the light is solid. It starts to cycle through the display options but automatically picks the second one which does not work. The screen is all light up and I can sort of make out the time but not really. I have tried reverting the SD card to older versions and rewriting and nothing seems to work. No matter what I do it automatically selects what appears to be the wrong display type. Any suggestions?? Thanks!
