Radeon Compatibility Guide - ATI/AMD Graphics Cards

Problem fixt. No more black screen

Could you please explain how you fixed it?

I think that’s our problem tomorrow I will get a dvi cable I hope this solve our problem.

I think the DVI cable will not solve the problem. Someone in another thread had a similar problem but was connected with native DVI on both sides.

If it does indeed fix the problem in your case, then that would mean I will have to get me a new monitor.

Hi there,

I am assuming the sleep issue is still affecting all ATI Radeon cards still correct? I have a R9 290X and just upgraded from El Capitan to High Sierra. I got everything to work and the graphic card is displaying fine. But when I put the system to sleep, it will not come back to life. The graphic card never triggers the monitor again.

I've tried setting darkwake=0.

I also tried setting my integrated Intel graphic as primary. Primary Init Graphic = iGFX. Then when I boot into the OS, the screen is just blank when I'm plugged into the ATI card. I can swap to the Intel DVI port, but its just a garbled graphic.

Any insight into this would be extremely helpful.

Can you share you config. Plist??

I have a 290x too, and I can't fixed the issue. I use a dvi -hdmi wire.

Well I got the DVI cable today, and now it is working!
The problem is I used a DVI to VGA cable.

But now I have one more problem. my second screen (left one) is now the main screen.
I want to change this but can't seem to find out how.

In the arrangement I see my two screens and the left one have the white bar above, how can I change this ?

I am so stupid just drag the white bar to the other screen, everything is working now including sound

Here's my config.plist. What problem are you having? Other than the system not being able to sleep, my audio also makes popping noises. El Capitan didn't give me any issues.

In the Capitan I dind't have any problem, except that the 290X boot on black Screen until login. But in High sierra I have the same problem, but it doesn't works. Always black screen.

I use a switch hdmi (for igfx, 290x, and one computer with win 2k16 Server) with the same screen. From computer to master switch i used a dvi to hdmi wire.

The only diferente between you config and mine, it's that you used imac 14,2 I used 15,1 and use in boot dart=0.

Congratulations m8! Glad it's working for you.

Since my monitor doesn't support anything except VGA I need to find another solution than buying a new one.
Everything was working in Sierra out of the box. I don't know what's changed, but I hope there'll be a software fix for it soon.

Hey, Thanks I have the same with Sierra it worked without any problem.

Your main screen only have HDMI or also dvi ? If it hase dvi maybe you can try to connect your hdmi to a tv and the dvi to your main screen. If you can get to the installer it should work.
