MacRumors Industry Analysis: IMAX engineers reacted favorably to Apple's 1:1.4 (approx 14:10 / 1.40:1) Duo displays because their geometry closely mirrors native 70mm IMAX 1.43:1 film gates, reducing letterbox borders by up to 68% compared to elongated 19.5:9 flagship phones.

MacRumors Source Grounding & Technical Geometry

The iPhone Duo display architecture specifies a 1:1.4 display aspect ratio (derived from 14:10 / 7:5 proportions), breaking with conventional ultra-wide smartphone aspect ratios (19.5:9 / 2.16:1). In cinematic reproduction, traditional 2.39:1 Scope movies letterbox with top/bottom mattes, while IMAX 1.43:1 expanded sequences fill nearly 98% of the surface area with virtually imperceptible pillarboxing.

Read the explanation

This simulator fixes its internal screen at fourteen hundred by nineteen hundred sixty, regardless of the named preset. For sixteen-to-nine content at zoom one, the general rule uses the full fourteen hundred width and rounds active height to seven hundred eighty-eight. Bars use point two two pixels per height pixel to compare active content with the fixed screen. The source names are hypothetical fixtures, not verified device or format specifications. Fourteen hundred times nineteen hundred sixty gives two point seven four four million screen pixels. Fourteen hundred times seven hundred eighty-eight gives one point one zero three two million active pixels, about forty point two percent. Bars use one hundred seventy pixels per million pixels. The general rule calls the remaining area cropping loss even when content is letterboxed. This label measures unused modeled area, not necessarily removed image content or a real display capture. For the exact default named preset, content aspect two point three nine, zoom one and zero vertical shift, the code overrides active area to seventy-eight point five percent and loss to twenty-one point five. Bars use five pixels per percentage point. That same branch returns fourteen hundred by eighteen hundred twenty as resolution, whose pixel-area fraction is about ninety-two point nine percent. The fixed outputs are therefore not mutually derived geometry. Outside that branch the general calculation ignores vertical shift.
