BetterDisplay with macOS 15.2 Beta Ultrawide Aspect Ratio #3694
-
|
macOS Sequoia 15.2 is required to support Mac Virtual Display Ultrawide on Apple Vision Pro. 10240x2880 resolution can be selected for this combination. Has anyone tested macOS 15.2 with a conventional Ultrawide display to see if the DCP frame buffers have been updated to support this resolution and 5120x1440 HiDPI? |

Yes, they don't seem to support it. The only change is at least Catalyst apps now don't crash with 8K+ virtual screens. |

Just so I understand: 7680x2160 physical resolution could be supported by BetterDisplay virtual screen 10240x2880, then scaled to 5120x1440 HiDPI. But macOS 15.2 beta does not offer this as a supported option, correct? Could higher resolutions/larger frame buffers be achieved by firmware update later or is it fixed in Apple Silicon architecture (M4 Pro)? Thank you! |

Yes, native framebuffer resolutions beyond 7680px horizontally does not seem to be possible at this point on any Apple Silicon chips, including the M4 Pro/Max. It might be possible to add this capability later by Apple with an updated DCP firmware but this is conjecture right now. |
