Yes, MST absolutely can do 4k at 60hz. This is what the first Dell 32" 4k used.
My rMBP has been able to do this since February, 2014. I was trying to get my RX 560 in mid 2018 to do this and it just was not possible via any means with Ubuntu 18.04. I ended up using an Nvidia 1040 with the binary drivers without issue. The nouveau driver for the 1040 was able to do it with a newer kernel than Ubuntu 18.04 had (I was using Arch for that test).
- vetinari 7y agoMy rMBP is not capable of doing that; not with Dell P2715Q. It works without MST, or with lower resolutions.
- wbond 7y agoWhich rMBP do you have? I have the late 2013 with the dedicated Nvidia card.
- vetinari 7y ago13" early 2015, Intel Iris 6100. To get two 4k@60 outputs, I have to run two cables (it has two TB2 ports). With daisy-chaining, I got mirroring at best (I didn't check refresh rate at the time, though).
