AMD Radeon 7700, only two monitors at any one time

AMD Radeon 7700 series, Driver Radeon Software Version 20.3.1 in Windows 10


I have three monitors plugged directly into the card. All three used to work perfectly up until I restarted the PC a few weeks ago. All three are connected with HDMI to mini-DP. If I have three of them connected, only two monitors display. If I disconnect one of the active monitors, then the third monitor works. I cannot get more than two at any one time. 


Windows seems to recognize the third monitor to an extent all three monitors are shown in Device Manager. Also, in the Windows Display setting, it shows a third monitor but trying to activate it and this pops up:

"The display settings could not be saved. Please try a different combination of settings". 

And then refuses to accept it.


So far I have

- updated & rolled-back graphics drivers

- dismantled the PC, cleaned it up, and put it back together

- switched out every cable

- hit it


Please help
