DP1 works fine with me on my r9 290, with flickering and animation lag. My Mac showed my r9 290 as AMD radeon 8XXX with 4 GB of ram.  DP2 is not working at all, any ways to fix the flickering and animation lags?

Yeah for the flickering just unplug the video cable from your card wait like 2 seconds and plug it back in  

 

kext edits should work in dp2 they do for me just download mine and put them in your kext folder

On Yosemite (using Ozmosis and MacPro3,1 on a GA-Z87X-OC) I added the ID and everything is fine so far with my R290 as long as I have one display connected to DP only. If I connect one to DVI I have a crash during boot (black screen).

 

So I thought I have to create a proper frame buffer for the inputs. As per default RadeonFramebuffer is used. Googled a bit how to construct one.

 

 

I came up with this one, patched the kext and forced Baladi to be used as a Framebuffer (only one present in AMD8000Controller)

 

ATOM BIOS Rom: 
SubsystemVendorID: 0x174b SubsystemID: 0xe285

Framebuffer I created from these infos:
 

00 04 00 00 04 03 00 00 00 01 00 00 12 04 01 01

00 08 00 00 04 02 00 00 00 01 00 00 22 05 02 03

04 00 00 00 14 02 00 00 00 01 00 00 11 02 03 04

04 00 00 00 14 02 00 00 00 01 00 00 10 00 04 06

 

Well does not work even if I only connect one display to DP, black screen during boot.

 

During my first tries I had it working just after adding the ID, by removing my display port connection, re-plugging it and then plugging in the 2nd display into a HDMI port while Yosemite was still running.

 

I went away, and when a display went to sleep Yosemite crashed. On reboot I had a black screen from there on and couldn't reproduce it.

 

So anyone got this figured out how to run multiple displays on a R290? I saw some youtube videos where ppl. were doing it for an R290X with a similar frame buffer (using the last DVIs as the first two) but no real instructions I can work with. As the R290X and R290 are basically identical connection wise it should be doable.

 

Any ideas?

Hi there. I have installed these Kexts onto my install and my Radeon 290 does work. It was booting to a black screen but then I installed clover and it stopped doing that which is great. However, I am getting artefacts and I know it's not the card.

When I get up close they redraw fine. Is this the buffer? is that what causes this? it's doing it in Borderlands 2 too.

Now that Yosemite final it out and various people have been playing with it including me.. both with ##### -> multi , and an install of ##### -> clover my card is dected as a 8xxx card or something and ati gl viewer shows the card and open cl is working.  The biggest Issue I have is that I can not get dual monitors to work at all and Im wondering if anyone on this thread has found a way yet?

Hello,

 

I have a working dual screen on a non-X R9 290.

 

I just followed this : http://www.youtube.c...h?v=wjV4p0fGdEc

 

My second screen does not work at boot (it stays black), but it does after suspend/resume, so at boot I just suspend activity and resume, it just work that way (I think I might just be lucky).

 

My two screens are connected via HDMI (primary) and DVI (black until suspend/resume), the integrated intel graphic is deactivated in bios.

Hello Iron,

 

I have a reference design R9 290 with*OUT* X, can I use HDMI outputing 3840x2160@30Hz to monitor(in windows it is OK).

 

Now, it is only 1080p option can be selected.

Anyone have a 290x working with dual monitors, if so could you explain how you did this.  I have clover, and a mb w/o integrated graphics (intel)

How is resolution of your monitor? Singal may passthrougth but actual display will show the resolution.
