+## EPD display
+
+The EPD used on the Chroma74H+ is very similar to the Waveshare 800x480 3-color display used on the Aeon Chroma74 **HOWEVER** it
+doesn't seem to support the partial window opcodes 0x91 and 0x92.<br>
+If these opcodes are avoided the display works with the same code as the Aeon Chroma74.
