4. Display monitor info via command line - Ask Ubuntu

   Yes there is, read-edid hardware information-gathering tool for VESA PnP monitors. This tool have two commands: get-edid and parse-edid: tools to retrieve and interpret monitor specifications using the VESA VBE DDC protocol. EDID (Extended Display Identification Data) is a metadata format for display devices to describe their capabilities to a video source.
   
   First:
   
   sudo apt-get install read-edid
   Then try:
   
   sudo get-edid | parse-edid

10. To everyone having issues · Issue #11 · HelTecAutomation/e-ink · GitHub

    By now you know this repository is crap. This is what worked for me on a 1.54 e-ink display. It should work on other sizes as well.
    
    NOTE: This display requires 3.3 data lines. It works on 5v data lines, but just barely. The display is not crisp. I've read it's possible to use a 10k/4k7 resistor divider for 5v data lines, but it didn't work for me.
    
    Download this library https://github.com/ZinggJM/GxEPD
    
    From Arduino IDE, open the example
    
    Select this display
    #include <GxGDEH0154D67/GxGDEH0154D67.h> // 1.54" b/w
    
    Use these pins
    GxIO_Class io(SPI, /CS=/ 10, /DC=/ 9, /RST=/ 8);
    GxEPD_Class display(io, /RST=/ 8, /BUSY=/ 7);
    
    Connect as follows (display / arduino):
    VCC / VCC
    GND / GND
    D/C / D9
    SDI / D11
    CS / D10
    CLK / D13
    BUSY / D7
