I'm using MCUFRIEND to control a 360x480 TFT LCD, and I'm trying to load 100x100 BMPs from a SD card. But it's slow enough that you can watch each line get drawn. Would a JPG be faster?
Can I store the BMP in the LCD buffer, and how do I know if my LCD has a buffer?
Yes, that happens when you draw something to the screen.
Most likely would have a buffer.
Probably slower, because of calculations required for it.

What board is controlling the display?
The driver is ILI9388
Maybe if you're using a Nextion display or similar with its own microcontroller. It also depends a lot on how exactly you draw the picture.
What Microcontroller is driving the screen?
I'm using a mega.
To be honest, I don't want to have to use a different display unless the MCUFRIEND library can be used with it, or a library which is just as easy to use. I've thought abut a Nextion display, but again the library doesn't look as good.
I'm would get a faster board....Mega runs to slow to be of any worth, in speedy bitmap rendering.
Or compress the images....But that'll take time to uncompress too.
