Original pixels are rectangular
Display features–Optional Macintosh XL Screen Kit modifies the screen to show Macintosh text and graphics with the correct proportions. Apple's current support note states 608 × 431 pixels with the kit. The kit requires updated MacWorks XL and a Macintosh-only hard disk, excluding a disk shared with Lisa 7/7 or Workshop
