I've learned there are a few different chips used for OLED drivers.

The SSH1106 needs more data sent to it than the SSD1306. The SSD1306 just gets bytes for the pixels. The SSH1106 has memory for four extra lines that are not displayed. I may do a PR to try to detect which kind of display is attached and adjust appropropriatrly.
