I recently bought the Samsung 27" ViewFinity S90PC 5K monitor (their competitor to the 27" Apple Studio Display).
Besides a Thunderbolt 4 input, this monitor also offers a second input via Mini DisplayPort.
The Thunderbolt 4 input is already occupied by my Mac Studio. I am looking to connect a 2018 Mac Mini via the Mini DisplayPort.
Initially, I tested a USB-C → Mini DisplayPort cable, but to my disappointment this only yielded a 30 Hz framerate at 4K, on the 2018 Mac Mini. I'm not sure why, but I did not have this problem using the same cable with a 2023 M2 MacBook Pro, which supported 60 Hz.
The other options I can imagine right now for the 2018 Mac Mini are:
1. HDMI to Mini DisplayPort.
2. I have a CalDigit TS3 Plus dock that I connect to the Mac Mini over Thunderbolt 3. The dock has a DisplayPort output port. Potentially I can find a cable (or adapter) that takes the dock DisplayPort output *as* Mini DisplayPort input on the monitor.
The first option (HDMI → Mini DisplayPort) probably works, but likely doesn't offer the best image quality.
The second option (DisplayPort → Mini DisplayPort); I'm uncertain whether it works. When browsing, I can't really say for sure if there exists any such cables or adapters. Granted, there exists many Mini DisplayPort → DisplayPort options, but I am looking for the opposite. Not sure if solutions are bi-directional?
What do you recommend me to do?
I am a little bummed that USB-C → Mini DisplayPort cable only offered 4K@30 Hz. Perhaps something to do DisplayPort versions on the 2018 Mac Mini, or perhaps the cable is bad. However, I am confident that full DisplayPort should work with this Mac Mini, as I've been running a 32" monitor over 4K@60 Hz in the past (assuming that the Thunderbolt 3 dock connection supports this with no particular peripherals connected).
