I finally managed to get my old computer backed up and moved over to the all-in-one this morning and I have plugged in the MST hub and now it seems I have my old three monitors back but the monitor on the all-in-one refuses to display. I can get it to work if I turn off one of the other three it seems but that is not going to work.
I am guessing that there is some setup that I have neglected to do here that hopefully will be obvious and simple to fix. Also the monitors seems to running off the Intel internal card rather than the dedicated and I am not sure why that may be…
Hoping you can help to get all four monitors working together.
