I call adafruit_displayio_sh1107.SH1107() with
display_offset=adafruit_displayio_sh1107.DISPLAY_OFFSET_ADAFRUIT_128x128_OLED_5297.
It's by trying.

If it's shifted in your display, try others:
-DISPLAY_OFFSET_ADAFRUIT_128x128_OLED_5297
-DISPLAY_OFFSET_ADAFRUIT_FEATHERWING_OLED_4650
-DISPLAY_OFFSET_PIMORONI_MONO_OLED_PIM374'

How to distinguish the hardware? please press menu , and if you can see the words in Setting: "Hardware version No.:XXXXX " then the device is made with latest hardware, it has the latest firmware, and now it doesn't need to upgrade.  If you can not see the words in Setting: "Hardware version No.:XXXXX ", then it is made with old hardware, and it can be upgraded with firmware 2.0.2, and if you confirm this, the firmware for the device with old hardware is attached.  By the way, the firmware 2.0.2 only fixes device with old hardware. The device with new hardware can not use this firmware to upgrade. - Download firmware from FNIRSI Official Web Site - Connect USB to PC - While 2C23T is OFF, press and hold MENU button, then press POWER button to power...
