HiDPI Resolutions for Ultra-Wide display

[jfiorato]

Since the upgrade to Sequoia, I've no longer been able to used scaled resolutions on my Asus PG49WCD display with a native resolution of 5120x1440 on my Macbook Pro with Apple Silicon (have tested M1 and M4).

Prior to Sequoia, I would have the scaled options in the Display settings, and was able to select a HiDPI resolution of 3840x1080. Now when I try and select that resolution, that resolution is only available as LoDPI.

After installing BetterDisplay, and following the instructions here, the BetterDisplay slider always jumps from 100% to 60% (3072x864).

I've tried adding a custom scaled resolution at the desired resolution, but that shows as "Currently available as LoDPI". I've tried 1 pixel difference in both width and height and those show as "Currently available as LoDPI" as well.

According to the display information, it should scale to 3840 HiDPI

I'm at a loss, and would really like to get that resolution back if possible. Any help would be appreciated.

Hi there, it should work on the M1 Pro (not on the entry level M1). On M4 usually the first "pipe horizontal limit value" takes effect, so native resolutions beyond that horizontal HiDPI resolution won't work, even though the hardware can output 3840px HiDPI (for example on 8K displays).

Ok, thanks for the prompt response. I presume if there was a workaround you'd have shared it. Have you heard any rumblings of an Apple remedy?

Some in the related Macrumors forum said Apple is looking into the issue and might come up with a fix, but that was way back and so far nothing. :/

@jfiorato if I may ask, what is the reason you go to that resolution over the native one?

Asking as I may be planning on purchasing this monitor.

Thanks.

I prefer a slightly larger text size for work.
