Trying to get M1 mini to connect to 30" Apple Display and only get 720p
Posted by: pRICE cUBE

I have a Mac mini and hooked the below adapter to my USB C port. I plugged the DVI from the monitor and the best I can get is 720p. There are no other resolution options in the system settings. I went with this adapter specifically because it claims to work with the 30" monitor. "LCD monitors and projectors, especially for 30-inch Apple Cinema Display, you can enjoy the ultimate widescreen canvas with a resolution of 2560 x 1600."

USB C to Dual Link DVI Active Adapter, CableCreation USB Type-C to DVI-I Adapter 2560 x 1600 Resolution USB-C to DVI Signal Fomat Converter [www.amazon.com]


Any ideas of what I might be doing wrong?

Have you plugged in the USB cable from the display to your computer?

Have you held the option key down when you clicked the "Scaled" button to see all of the resolution options in the Displays pref's?

Why does Apple expect one have to hold option down to get more options? How would any user at my level or lower know this?

Agreed. They did away with File: Save As... but the Option key exposes it again.
It's burned into my brain now.

Wow! Annoying, but I'll be happy to have access to that again! I still find the "Duplicate" option incredibly annoying.

That whole file naming change has been a disaster for the user. It made no sense.

A developer at PANIC suggested they did it for Spotlight reasons. I never understood it.

It's not Spotlight.

It's because they implemented versioning, tied to the original document. When you "duplicate" you're preserving the document's history, but forking it. When you do a save-as or copy a document in the Finder, you're severing your copy from the document's history.

I've always dislike that, from the jump.

I can see how it makes sense if one is using Time Machine, which I assume is the reason for versioning.

Maybe, I don't know.

But once I found that Save As was alive, and just hidden, it's what I use.




I am that Masked Man.

Your boos mean nothing to me, I've seen what you cheer for.

Insisting on your rights without acknowledging your responsibilities isn’t freedom, it’s adolescence.

I've been to the edge of the map, and there be monsters.

We are a government of laws, not men.

Everybody counts or nobody counts.

When a good man is hurt,
all who would be called good
must suffer with him.

You and I have memories longer than the road that stretches out ahead.

There is no safety for honest men except
by believing all possible evil of evil men.

We don’t do focus groups. They just ensure that you don’t offend anyone, and produce bland inoffensive products. —Sir Jonathan Ive

An armed society is a polite society.
And hope is a lousy defense.

You make me pull, I'll put you down.

I *love* SIGs. It's Glocks I hate.

Oh, wow. I knew about the Option thing for monitor res (because I've had my own battles with that), but I had no clue about Save As. Thanks!

My Displays panel shows



If you select "scaled" you can choose from several options.

No need for option key.

I am using Catalina.

From that screenshot, you are using a Gigabyte M32U 4K (High DPI/Retina) display that is recognized as such by the OS, connected via a modern Displayport or USB-C (which is Displayport for this purpose) or HDMI 2.0/2.1 cable.

That's a very different circumstance vs using an adapter to connect a 17 year old LED Cinema Display with DVI.
