Vision Pro Ultrawide - auto detect proportions

[dmkpoznan]

Hi,

as today Ultrawide on Vision Pro finally landed I would love to prepare different resolution & proportions presets for different settings of ultrawide. Long story short: in ultrawide mode you can select 3 different proportions (starting from regular 4K - normal, wide, up to 2x4K - ultrawide). But it's identified as same monitor, so you can have only one virtual screen that automatically connects only with one set of proportions (as far as I know we can't decide which of virtual screens will connect based on screen proportions?).

I would love this feature!

I don't have a Vision Pro - how can you switch these resolutions normally? Using System Settings/Displays?

Can you run this command in Terminal and let me know the results when in each mode?

/Applications/BetterDisplay.app/Contents/MacOS/BetterDisplay get -n=vision -displayModeList

Let me know @dmkpoznan if you can help by running that command. But based on reports I believe the various resolutions should simply be available as Display Modes. So you can go to the Display Mode menu, click Filter/Show All and add any of the resolutions/aspect ratios you prefer as favorites.

I will. I'm planning describing how it works in details.

I've seen some videos on it (how you can switch using the Vision Pro). But as I saw in some screenshots, the various aspect ratios are also available at the Mac side in System Settings/Displays. But now as I rechecked the screenshots, this might not be the case.

I also misunderstood the original request - I see that you'd like to have BetterDisplay use the reported native aspect ratio as a kind of an additional display identifier. I can add this as an option.

Ok. Let me explain. On AVP there is new mode called "ultrawide". It allows you to switch between three different options of resolutions with different proportions - from regular 4K resolution up to 2x4K resolution. You can select it when you are already connected and switch it dynamically (without reconnecting). Here is menu:

What's changing? Aspect ratio of screen. I used to use mirroring of virtual screen to keep resolution on HiDPI (doubling pixel density from 4K to 8K).

What I want to do? I would like to dynamically switch proportion of virtual screen that is mirrored to AVP screen to keep aspect ratio same as main screen.

Maybe there is better way of implementing that, but for now, when I change mode from ultrawide to normal (for example) everything is stretched / compressed, so it's useless. For now I need three different virtual screens, disabled autoconnect and reconnect AVP each time I want to change mode, then connect right virtual screen.

Is this clear enough for you? Should I record you some video?

I see. With native aspect ratio added as an optional identifier the variants will be detected as separate displays in the app - so you can create and associate separate virtual screens for them.

But - the default modes are already HiDPI. Why do you need the additional virtual screen? You need different resolutions?

[dmkpoznan]

Normally you have only few resolutions available - like 5120x1440 HiDPI or 7680x2160. You can say that second resolution is 2x4K and should be enough. But I have double resolution (HiDPI) on all screens like Studio Display, where resolution is 8K. This is really useful when you use fullscreen zoom a lot or do some screenshots. Same situation on AVP - I'm rendering 2x4Kx2, so massive screen, but thanks to M1 Max CPU everything is running smoothly.

So basically what I'm missing is resolution like 7680x2160 HiDPI for ultrawide, 5040x2160 HiDPI for wide and 4K HiDPI for normal. And I love elastic resolution scalling that is available for physical displays... I'm using it as often as brightness control.

This is how it's looks like.

Small update: I was playing with native resolutions available "as is" without creating virtual display and I found, that changing between normal/wide/ultrawide mode cause to forgot last resolution for each mode. It could also be related with dynamic change of screen propotions..?
