Hi this is a really great library, I hope its possible to drive 2K display with vga input with this library, Sla printers does not require complicated displays to print a 3d object and it only just shows a black and white image from sd card for over a minute of exposure to uv. esp32 now comes with external 4-8MB ram chip which could be used as buffer for the 2k display. Some articles mentioned that vga are capable of 2K resolution at max but I dont know if esp32s with external psram are really capable upto that resolution.

As the author mentioned in their introduction video, the ESP32 is not only limited by memory, but also by the speed of the I2S module... you aren't gonna be able to get 2K on it, sorry for the bad news. Try a cheap Pi instead
