1280x720x6 (6 bit required to have 64 colors) resolution needs 691200 bytes of internal RAM, too much for the ESP32... |

Using a model with PSRAM can I achieve a resolution of 1280x720 with 26 colors? |

unfortunately no. The frame buffer must be allocated in internal memory. |

Can I change any hardcoded values in your library to get 1280x720 instead of 640x480? |

resolutions aren't hard coded. FabGL uses modelines (like linux modelines) to define resolution and VGA timings. Please look at fabglconf.h: here there a some modelines, but you can write your own. |
