Allow panel native HiDPI resolution (latest Ventura beta) and ultra-high-res native scaled resolutions (for future)

[waydabber]

The latest Ventura beta seems to allow native resolutions in HiDPI with display config editing. Also future macOS versions might allow higher-than-native HiDPI resolutions (who knows?). There should be some toggles that allows these possibilities for the slider and native smooth scaling.

[waydabber]

This setting will apply to native smooth scaling as well. Might work in the future.

[waydabber]

Resolutions marked as Invalid in the past will be marked as Discouraged instead as they might work and be useful.

[waydabber]

From now on discouraged modes will appear in the list when this is enabled. Also, in this case the slider maximum will attempt to use HiDPI for native resolution instead of LoDPI.

[waydabber]

Here is a pre-beta to test if this works.

It would be great if Apple Pro Display XDR users would be able to check if additional resolution options are enabled in Ventura dev beta 4 for that display or not (as it might be the case that 4K HiDPI became available on that display as well).

(download removed)

Here is how to test if things changed.

• Enable Settings (gear icon) -> Advanced > Enalbe resolutions over 8K just to make sure
• Enable Settings (gear icon) -> App Menu > Allow discouraged resolution modes
• Optionally switch to Always use resolution submenu for better control and allow all resolution selector options under Settings (gear icon) -> App Menu
• Go to Settings (gear icon) -> Displays and enable Edit and manage the system configuration of this display
• Enable Allow smooth resolution scale, click on Apply in the bottom red banner, enter credentials and reboot when instructed.

The new thing should be that panel native resolution should be available as HiDPI in Ventura beta 4. Also, possibly more resolutions might be unlocked in certain displays (ultrawides? / Pro Display XDR?). These need confirmation.

Very Nice!! Did u think this will fix Pro Display XDR 4k HiDPI issue ? Nice that u keep on working on issues and limitation coming with apple silicon!! Hopefully this will help getting 4k HiDPI on PDXDR. Unfortunately i have not Ventura Beta installed to test this for you :-( Testet your beta with MacOS 12.5 and still the same.

[waydabber]

Yes, I am just curious whether the situation regarding the Pro Display XDR is affected by this change in beta4. 4K HiDPI (=8K framebuffer) is now certainly possible on a 4K display (was not possible before), so it would make sense that it is unlocked with the PDXDR as well - but that might not be the case.

[Zorast]

Probably i think there also come a new Firmware for the PDXDR itself too to support this?!

[Zorast]

Now with MacOS 12.5 we have: Display-Firmware-Version: 4.2.37

[waydabber]

I am not sure if a firmware update is required this on the display size as only scaling is being changed which should not affect the video signal itself. But I don't have a Pro Display XDR (would be nice to have one laying around though :)) so I can't really experiment with it.

[Zorast]

Haha hopefully the sales with BetterDisplay with reach fast that u can get them :) But be aware this Display has some hardware issues too: https://youtu.be/ZNlLm82q1xs?t=352

I mentioned this in Discord but thought maybe should document it here for safekeeping:

I might have misunderstood, but I was hoping this could allow the LG 34WK95-U to get native 5120x2160 in HiDPI, so I tried your new beta with Ventura Beta 4, but no luck. I did get a 3830x2160 HiDPI "Discouraged" option that was I was able to activate but of course the ratio was wrong so it was unusable. I did not get any new HiDPI resolutions higher than 1620p. I'm still hopeful. So close.

Thanks again for all your hard work.

Hi @Mudflapper - yes, this change does not seem to affect the 3072 (M1/M2) /3840 (M1 Pro) horizontal limit.

[waydabber]

Ventura beta 5 killed this feature. :( The fact that it worked was a bug apparently...

[Zorast]

Crazy...
