Starting a new display thread since it's a different display and the old thread is really long.
I finally got the reprap discount graphics display as directed. I installed it and have that display selected in Marlin. My problem now is that most of what's on the screen is unreadable garbage. I have the EXP1 cable the right direction obviously as it wouldn't power up the other way. The display doesn't seem to care if the EXP2 cable is connected at all. I've tried that cable both ways and disconnected and the display never changes. I know there's a pic in the wiki on how to set the cables and I tried that, and other variations. Any help?
