I've got plenty of speed alright, I should have mentioned that I'm using a 32 bit MCU @ 168 MHz. What I want, however, is instant :). The idea is to play (low framerate) video and I figure it will look better if the data is sent into the displays RAM first, with the screen being updated once the RAM is filled, as opposed to updating each pixel at the speed the MCU can send data, making it slightly noticable that the screen is updating from one side to the other. So essentially I need to manually control the refresh/update rate of the screen or somehow stop it from displaying new data until I tell it to.
