Have you changed the screen driver object to the 3 Colour version? You get that from the GxEPD2 library. Try this: GxEPD2_3C<GxEPD2_420c, GxEPD2_420c::HEIGHT> display(GxEPD2_420c(/CS=5/ SS, /DC=/ 17, /RST=/ 16, /BUSY=/ 4)); // GDEW042Z15
Change the pins to match so CS is the same as your definition, SS and so on
Hello there, i had a spare 4.2 inch E-Paper Module from waveshare laying around and tried to get started. Well from the Serial everything seems fine, and after changing the "display_init();" it even displays... well something. My display isnt showing everything, only the upper left part and the 90 degree flipped 0 on the right.

the Board i use is the Lolin ESP32 lite and the Display is the 4.2 - 3 Color Waveshare E-Ink module ( i guess first version). Here is a short snippet of the Serial Console:
oh, and the GxEPD2 Example does somethin similar when the test text is displayed. the Fullscreen Images on the other hand work just fine.
