PIC32MZ DA Resolution capability

please allow me to briefly give you some important background info; I am a 40y old hobbyist trying to always learn new things. 
About 10y ago, I built an arcade for my son, and now I want to add some "cool" features to this arcade.
I would like to experiment with a PIC32MZ DA MCU to steer an external TFT display (for the marquee btw)
The display is preferably a bar TFT display; the one I have in mind is the IR195HE05-R215 to be specific, which has a 1920x540 resolution.
However, I have a few questions...
1. From the research I did on this forum etc I understood it should probably be possible to get it working with the PIC32MZ DA. Or am I wrong about that ? How do you calculate if it is feasible ... ? Or what parameters does one have to check on the TFT datasheet ... ?
2. The most important thing for me; is actually only showing just some images; no video; that should probably be simplify requirements ... ?
3. I am trying to figure out if I would need a PIC32MZ DA with or without internal 32MB.... Which one would actually be "faster" ... ? On one hand, I assumed the internal DDR2 RAM would be faster, but I am not sure...? How do I need to calculate the right decision ?
4. Since the resolution is 1920 x 540; even in 24bit color depth, this would represent a frame buffer of 4,147,200bytes (1920x540x4) , right ? So; the 32MB should always be enough...? Why would I ever choose an external RAM...? What would be the possible benefits... ?
Please bear in my mind, I have ZERO experience of working with TFT displays; this is just something I wish to learn. Yes, I know, I could be better and cheaper off with a Raspberry etc etc; I just want to experiment and learn.... :-)
Hope somebody can enlighten me on the subject...
Kind regards,
