The command sequence {
0x10,0x02,0xB0 | page} gets interpreted (at least on my SSD1306 GME12864 module) as three command:1.
0x10: Set Higher Column Start Address for Page Addressing Mode (10h~1Fh) to value 02.
0x02Set Lower Column Start Address for Page Addressing Mode (00h~0Fh) to value 23.
0xB0Set Page Start Address for Page Addressing Mode (B0h~B7h) to valuepageThe first two commands result in the first two columns of display pixels displaying garbage and the last two columns of the frame not getting displayed, so I removed them.
SSD1106 should behave the same way like SH1106 in Page Addressing Mode, but I don't have SH1106 hardware laying arround, so I can't test it. Maybe @TomSaw could check?

And the hardware test shows:
These lines have a purpose. Whitout, the displays pages (columns of pixels) get ugly shifted.
I remember having read about this necessary micro-management in an adafruit or arduino library comment, not in the datasheet or elsewhere.
