If you want to do monochrome bit-mapped graphics on a -500 part you have 368,640 bits of block RAM, so just enough for 640x480.

 

If you want to do tile-based graphics (e.g. have a choice of 256 x 8x8 tiles, with 8 bit colour per pixel) You could use 16,384 bytes for the tiles, then another 14,400 bytes to hold a 160x90 map of what tiles are in use, giving a 256 colour 1280x720 output.
