I'm not sure what you're asking.  Let me try to do it as a set of addresses.
If the display list entry has a pointer to $E000, is 4 bytes wide, and the
zone is 8 lines high, the MARIA would read data from:

E700 E701 E702 E703
E600 E601 E602 E603
E500 E501 E502 E503
E400 E401 E402 E403
E300 E301 E302 E303
E200 E201 E202 E203
E100 E101 E102 E103
E000 E001 E002 E003
