Overview
Diablo IV natively supports 21:9. Ultra-widescreen is capped at up to a 3:1 aspect ratio, so true 32:9 monitors (3.56:1, e.g. 5120x1440) don't get the full native width — expect some pillarboxing on 32:9 even though the game isn't locked to 16:9.

Fixes
No safe fix available.
No ultrawide-fix modification is documented for Diablo IV. It's an always-online, server-authoritative game with active anti-cheat, so UltraWideCheck does not recommend any injection-based workaround for it.
Community reports
5120×1440
Not working
Full 32:9 width is capped — game renders up to roughly a 3:1 ratio, so 5120x1440 shows pillarboxing.
