Two apparently identical displays might have different configurations. The most common issues are: 4 5 * Colors are inverted (black is white and viceversa), invert the colors with display.InvertColors(true) 6 * Colors are not right (red is blue and viceversa, but green is ok), some displays uses BRG instead of RGB for defining colors, change the mode with display.IsBGR(true) 7 * There is noise/snow/confetti in the screen, probably rows and columns offsets are wrong, configure them with st7735.Config{RowOffset:XX, ColumnOffset:YY} 8 9 If nothing of the above works, your device may need a different boot-up process.
