P: Mac M1 Mini Can't use 30 bit on Photoshop 2021 or 2022, but 2021 works.

[ucphotog]

There was a similar discussion about a Macbook M1 Air, with a workaround / solution. The solution involved using "Presets" in "System Prefs > Displays". I don't see a way to make that applicable to the Mac M1 Mini.

I have confirmed that the M1 Mini will display a 30 bit (10-bit per channel) image in many applications. Indeed, it will display a 10 bit grayscale gradient in 30 bit mode correctly in Photoshop 2020. However, nothing I have thought of and/or tried has been able to make the 30 bit option available in Photoshop 2021 or 2022.

Sorry. Messed up the title/subject line. It should say "But Photoshop 2020 works."

What does the Performance dialogs display? A screen shot like this could help:

It may help if we could see your Photoshop System Info. Launch Photoshop, and select Help >System Info...and copy/paste the text in a reply.

I should have attached better documentation. Sorry. I simply can't see anything else, so it is easy to assume it is pervasive.

My comments on the images seem to have been lost. The upper image is 2022. The lower is 2020.

Thanks for your help.

[Mark C. Dahm]

@ucphotog , what is the format of the document you are working on? What does the option say if you don't have any documents open?

[ucphotog]

The only format I know for sure that I have tried is PSD. JPG is likely, but I'm not 100% positive that I checked that option with a jpeg open.

[Mark.Dahm]

@ucphotog can you tell if 30 bit display is working (despite the appearance of the option)? Working on getting this to act up in our labs; presuming you are running Photoshop natively (not Rosetta); please confirm; thanks!

[PECourtejoie]

Bump, @ucphotog any news on your end, especially with the new versions?

[ucphotog]

Question 1: Can I tell if 30 bit is working, even if the option isn't set. Sorry, I don't know how I would check that. I'll be glad to run some commands to confirm, if you can tell me how.

Question 2: What about recent versions? Good question. I had forgotten to check. 2023 version shows a grayed out 30 bit option, just like 2022.

Also, sorry. I got an email about the last question, but didn't get one about the previous question, or I missed seeing it.

In any case, thanks for the follow up.

[PECourtejoie]

Hi, wasn't there a file with a long gradient? Isn't there a link on this page? https://www.pugetsystems.com/labs/articles/how-to-enable-30-bit-in-photoshop-1243/

Pinging @D Fosse

You can just draw up a radial gradient in a 16 bit file and look. If there is 8 bit display banding you will see it. A shallow gradient works best, something like this. There will obviously be a lot of banding in this 8 bit PNG displayed in a browser, so you get an idea of what it looks like.

Use PSD or TIFF. Jpeg renders the whole exercise moot, it's always 8 bit! Avoid compression, and turn off dither in the options bar.

On Windows you need to enable 30 bit in the GPU driver, but I suppose that doesn't apply on Mac.

FWIW 30 bit has always worked reliably here on Win 10 pro, on every PS version.

[TheDigitalDog]

Here's a document to test high bit display path, ready to download and use for testing (and yes, you must view at 100% zoom, and yes, the Performance dialog Jeffery shows should be indicate a high bit display path):

https://www.dropbox.com/s/s14f4w7dq85r7oo/10-bit-test-ramp.zip?dl=0

[ucphotog]

I opened the image "10 bit test ramp.psd" from dropbox, and it has distinct steps. PS says that the image is RGB 16 bit.

However, if I open an RGB 16 bit or 32 bit image and drag a gradient across the image, it looks quite smooth. Certainly no distinct steps.

By the way, does it matter what monitor I'm using? I have a BenQ 270C.

Thanks for all of the help here.

I opened the image "10 bit test ramp.psd" from dropbox, and it has distinct steps. PS says that the image is RGB 16 bit.

Then you don't really have a full, high bit display path or it would be smooth. Yes, the display matters too. Many are not high bit (some are not even 8-bits per color).

Yes, that test image is in 16-bit. 

[Lumigraphics]

I have an M1 mini and that 30-bit box is checked and greyed out. I do not have a 30-bit display. How are you connecting- USB-C or HDMI?

[TheDigitalDog]

You don't need a 30-bit display but one with more than 8-bits per color in the panel and the rest of the video path. But it sounds like you so if the PS checkbox is on/grayed out. So not sure why you're see banding on the test document (I see none).

I'm using DisplayPort on a SpectraView.

[D Fosse]

According to Eizo, DisplayPort or USB-C, both will work: https://www.eizoglobal.com/support/compatibility/gpu/10-bit-photoshop18orlater-mac/index.html 

You can't use HDMI, it doesn't have the necessary bandwidth.

The 30 bit checkbox in Photoshop just means that PS is outputting 30 bit data. It doesn't know about the rest of the chain (GPU > interface > display panel), it all has to support it.

[PECourtejoie]

Hello, according to https://www.benq.eu/en-uk/monitor/photographer/sw270c/specifications.html this display is supposed to support billion of colors, usually the 10 bits per channel. and it is listed as supporting HDR10.

[Lumigraphics]

The M1 mini has HDMI and two USB-C/Thunderbolt 4 ports. Sounds like you'd need either a Thunderbolt display or DisplayPort over USB-C.

[TheDigitalDog]

Hello, according to https://www.benq.eu/en-uk/monitor/photographer/sw270c/specifications.html this display is supposed to support billion of colors, usually the 10 bits per channel.

Marketing rubbish, but all the display manufacturers make similar claims (no, they do not support or produce billions of colors, they might produce billions of device values* and that's a huge difference). Ditto for scanners or anything else making such a claim. 

Yes, that panel may very well be high bit. But again, the entire video path has to support high bit, including the OS and the software. That is doable. And again, the 30-bit check box should show us that being the case. So why the test image shows banding is something worth looking into. Of course it has to be viewed at 100% (1:1). And again, on my system, it is utterly smooth everywhere. Yes, it is possible that the cabling used from (Mac?) to display is an issue.

Thanks for all of the informative updates.

The BenQ is connected via USB-C male-to-male connector directly from the back of the Mac Mini itself.

Using the HDMI on a Mac Mini produces something ... awful. Makes everything look oversharpened and not good. I use the HDMI for a second monitor--a Dell U2713H. In any case, the BenQ is not hooked up via HDMI.

The chain involved in the USB-C / Displayport path is literally USB-C connector directly on the back of the Mini, though a several foot usb-c cable, Thunderbolt 3 acceptable, and into the USB-C port on the BenQ monitor. So, I think we can safely eliminate lower bandwidth portions of the path.

The comment about checked and grayed out was interesting. I'd be happy with that, but to be paranoid I confirmed that in PS23, it is still grayed out and not checked.

I have looked at 10 bit images or at least what I had reason to believe were, previously, and they looked smooth. I'm actually puzzled why that specific sample image looked bad. Maybe it is just an odd path in the code behind the checkbox, and that the data path is a clean 10-bit? I wouldn't deny, but the grayed out box is puzzling. Also given that an old release of PS shows it as 10 bit, tends to support a 10-bit per channel data path.

In any case, I appreciate all of the support here. At this point I'm reasonably sure the data path is 10-bit per channel, and that PS is mostly behaving that way, this one recent example seeming to be an exception. In any case, it doesn't seem to be anything simple or with an obvious workaround, so I'll just proceed with what I have. And again, I really appreciate all of the input, suggestions, and help.

Even though I have this 10-bit test on my Mac, I tried downloading it from Dropbox to make sure nothing funny happened to it (like maybe somehow I uploaded a JPEG etc). Well, it looks as expected on my SpectraView in the latest version of PS on macOS 13.0.1 at 100% zoom. 

The 30-bit check box is grayed out, and more importantly, there's a check mark.
