Thanks for the reply. I now understand what is the difference in initializing the display 9320. Also wanted to ask why You said that the display on the UNO Board will run faster than on-Board MEGA 2560.
Also, this question is a bit off topic, but associated with the display. To display the images with the SD card uses the SPI library with hardware support. But since my display Pinout charge made under UNO, it is not the same SPI pins. For UNO - 10, 11, 12, 13, and MEGA - 50, 51, 52, 53. a question arises, is it possible to use software SPI, SPI by assigning findings on 10,11,12,13?
