Hello, I've got a Mac Pro 7,1 with an W5700x, and an Apple Cinema Display, that only displays resolution till 1280x720, ive tried everything in this list so far :
and the problem persists, any information would be really appreciated
Thanks! Solved the issue , the extension cable seemed to have failed (?) replaced it and the system worked correctly thanks a lot for your advice.

exactly what cables and adapters are being used for this connection?
Menu > About This Mac > (System Report) > Graphics & Displays ...
has two line items for a display:
• [actual] Resolution:
• UI [User Interface} Looks like:
When you choose scaled, you will see the 'UI looks like' numbers ONLY, not the [Actual] resolution. To avoid text being microscopic, it is scaled up by 1.2 or 1.5 or 1.8 or 2x what it would normally look like so you can read it.
Your adapter looks OK, and you don't appear to have exceeded the graphics card's ability to drive displays.
Another interesting experiment might be to disconnect one of the other displays and see if the problem display resolution can be set higher.
What ports on the computer are you using to connect these displays? All on the card? Some on the I/O card? Some on the top? Which is which?
so the typical way to proceed would be to continue to substitute "known good" things until something follows a specific device.
You tried the cord, maybe next the adapter?
Grant, thanks a lot for your prompt response,
here's the information the menu gives , im worried because the Apple Cinema Display used to work with no issues, but now it seems like its stock in this low resolution, can it be the video card gone wrong?
This is the cable im using
CalDigit USB Type-C to DisplayPort 1.2 Adapter
Hello, im sorry to be a nuisance but it happened again, i went away from computer and when i returned it wouldn't wake up from idle, i had to do a hard reset and now it i wont recognize full resolution on that display again.
agree, you are right, thanks. Im gonna order some new adapters... this all feels strange for some reason, I come from a solid 5,1 Mac Pro, never had any issues like this in over ten years. I have a feeling its the graphic card...
Anyways, thanks a lot for your advices as always!
