Hello, I've recently got an Mac Pro 2013.
I had an issue with DELL U3818DW Display. The computer simply freezes and the display looses the signal.
After a lot of tests, I finally got rid of the problem by disabling the 60Hz refresh rate of the monitor.
Does anybody know some 4K monitor (preferred from Dell) that work's at 60Hz at 4k resolution?
Thank's
Mac Pro, macOS 10.15
That's what I'm already doing. I'm using a cable Thunderbolt/DisplayPort.
I know that Hdmi port of MacPro doesn't support 4k.
But with this dell monitor, I can't use 60Hz rate, or the Mac freezes...I think this problem is only with this specific monitor, my question is If someone can confirm me some 4K monitor that works on 60Hz with this Mac...thats what I'm looking....
cheers!

yeah....I already have a lot of cables thunderbolt / hdmi, thunderbolt/DP.....but my question is witch model of monitor will really work....because this DELL U3818DW Display, that cost me a lot to buy, can't be on 60Hz or the MacPro freeze...so It appears to be an issue with this specific monitor....now I wanna know for sure an monitor that will work without issues....
Use the display you have, just not on the Direct HDMI port, which uses old technology and that PORT cannot achieve 4K.
I recommend you connect directly with a Mini DisplayPort cable -- no adapters, simple and trouble-free.
I also thought...but the problem occurs with all thunderbolt, hdmi ports...I already took the computer on two authorised apple for diagnostic...and everything was right...(at the time I thought the problem was with the computer, than I tried lots of cables, and finally I got rid of the problem by disabling 60Hz refresh rate).
The built-in Thunderbolt port is too old to support 4K at 60 Hz.
Use an adapter from the ThunderBolt-2/Mini DisplayPort to HDMI.
Yes,
Thunderbolt 1 and 2 can be very annoying for high refresh-rates and resolutions. Just use an adapter.
I think your Mac Pro may have a hardware problem. Try the other Busses using this diagram for guidance:
