Need help setting up 6 monitors on rx 580

[Duck Phobert]

Hey guys just finished putting together my new build. I do some gaming but this is more for work. I want to be able to hook up 6 monitors I have heard there are lots of problems with those MST hubs and didnt want to have to deal with that. I have also heard that the MST hubs cant support the bandwith to run two 1440p monitors at 144hz from one display port 1.2.  So I bought 2 Asus dual rx 580s. I have updated all the drivers on the computer that I knew of and also ran snappy driver installer to make sure everything is up to date. I hooked up three of my monitors up to one card and three up to the other card, via 2 display ports and one hdmi port on each card. I have only been able to get the monitors from one of the cards to work. The other three monitors come on during a restart but then quickly give a no signal message and go back to sleep. I have heard that the second card may be configured as a slave GPU and wont have active I/O ports. What can I do to get this working? I have spent a week already troubleshooting everything else in this build and do not want to waist any more time. Here are the specs for my build. Any help would be greatly appreciated.

why in gods name do you have 6 monitors

[Duck Phobert]

I run 3 different business. I need to keep security cameras, and gps trackers up on one monitor, I have a server that i like to stay remoted into so i can keep an eye on my Virtual machines, one for my personal stuff (phone service and email) one monitor for the email providers for my companies, one for what im actually working on the other for reference and spread sheets. .

While your threadripper is probably up to the task:

 

Running an additional PC to split those tasks could save a lot of problems over time...

[Duck Phobert]

I have already bough the hardware and set it up. I just need to know how to get the monitors to work.

[Glenwing]

Normally you plug the monitors in and they just work. You don't need to configure anything to run monitors on multiple graphics cards.

 

If you take the first (working) card out and only use the second card, can you get display output from it?

[Duck Phobert]

When I take the first working card out the other three start working and show just fine. When I reinstall the card everything switches back to the first card again. The other three monitors say no signal and go back to sleep.

Solved: I finally found a setting in the Radeon control panel that had set crossfire set to on. When I disabled crossifre it immediately recognized all of the additional screens. Thanks everyone for the help!
