Display blinking with 3 outputs using Ryzen and AMD RX580

[renanmarc]

Hello,

I have been trying a new build, this time I am using and AMD Ryzen 7 1700 and a crossfire rx 580, I have tried hooking up 3 outputs, but whenever I try to set them up on the advanced output, resolume instant starts to blink when I activate the 3rd output, the fps drop to around 5, and all the displays blink as well, but when I close the software, it instantly stops the blinking, so it's a specific issue with resolume. I have tried using a bunch of resolume versions such as 5.0 and 4.2.2. I am running the demo version. I have also already tried installing a different version of windows without the uptades but no success at all.

Thanks in advance.

This is a problem with creating a spanning OpenGL context over two AMD cards. Unfortunately there is nothing we can do about it.

One thing you can try is to create an Eyefinity group containing all the displays, and then use Arena's advanced output to assign the individual outputs.

Oooh, it's good to know that you already know what's causing this, I am not too fond to try and solve this problem with the eyefinity configuration, I am just returning the cards and getting the gtx 1070's instead, but anyway, thank you for the quick response!
What's weird is that I have the same build, but with a crossfired rx 470 and I never had this problem, I have already used 5 outputs at a time.

That's a decision you won't regret!

It may also have to do with your adapters. Are you sure all your adapters are active ones?

I should have specified it's a problem with *some* AMD cards. Windows will be able to access each monitor just fine. But the moment we try to span an OpenGL context over all the outputs, they get very confused and start blinking.

We had a setup with the problem in the office for a while. We had a completely stripped down version of Resolume running on it, trying to figure out what the problem could be. At one point, we were down to just trying to display one giant red rectangle on all displays.

In the end, we had to give up, because spanning the monitors like that is part of the core of how Resolume works.

I was trying to give a chance to polaris cause I like their color better, but with this bugs and the lack of raw horse power, there's no way to stick with polaris, maybe the new vega takes a huge step from the Polaris architecture.

I was not even using adapters, I was using 2 dvi outputs and one HDMI.

Yeah, I have built this machine specificaly to work with monitor spaning, there was no way I could live with just 2 outputs in a crossfire config.
