Marlin: Custom Welcome Image For Large 128x64 Full Graphic LCD - Having trouble exceeding 64x64 image... Any Advice?

I am trying to get my custom image into the Marlin firmware. Its 110x64, and I want to get it to show up when the device boots.

The current image is 64x64 and I am able to change that by going to DOGMbitmaps.h and pasting in a new array of bytes under

const unsigned char start_bmp[] PROGMEM = {

However, if I feed in anything larger than 64x64, I get a garbled image when booting the firmware...



Can someone point me in the right direction for this please? thanks

What is make / type of Display?
Did provider point you to firmware to drive it?

I have never seen a Arduino RAMPS drive anything but a 4 row LCD.
