MattsCreative Posted January 26, 2015 Share Posted January 26, 2015 If you're successful with a DVI patch, please share it. Otherwise, I think I might get one of those DisplayPort to DL-DVI adapters to try. skip the patch and go for dvi to dp cable http://www.amazon.ca/Cable-Matters-Gold-Plated-DisplayPort/dp/B004C9M7UG Link to comment Share on other sites More sharing options...
Awesome Donkey Posted January 26, 2015 Share Posted January 26, 2015 Sadly, that cable won't work for dual-link DVI. You need an active adapter, and those cost between $65 to $100. And even then, I'm not sure if it'd even work or make a difference. Link to comment Share on other sites More sharing options...
Neo.Luxembourg Posted January 27, 2015 Share Posted January 27, 2015 I don't think the problem is related to the framebuffer, it's more like a bug in the driver. Enabling my iGPU and setting it as primary does no produce the black screen, but I have full acceleration on the 290X. How could it be related the the framebuffer? I will try it anyway this week when I have some time, but I don't feel like that's gona help at all. Link to comment Share on other sites More sharing options...

If you use a passive DVI to DP adapter like that cable on a 1440p DVI-DL screen, you're limited to a max resolution of 1920x1200. If you want full 2560x1440 DVI-DL to DP support, you need an active USB-powered adapter regardless of the video card used. I'm going to order the Dell BIZLINK XT625 for about $40 (cheaper than the Apple one, and it's got better reviews) and see if it finally addresses the issue. Of course, anyone wanting to go the active USB-powered adapter route needs to keep in mind you may encounter issues like snow and flickering due to possible lack of power from a computer's USB ports. I researched this and found it's better to plug the USB into a USB wall adapter instead of the computer. Link to comment Share on other sites More sharing options...

MacFaulty Posted January 29, 2015 Share Posted January 29, 2015 (edited) Hmm... Purchased a passive DP > HDMI converter, but on start the screen is still flickering and have to replug the darn connector. Is there a patch for this or do I need a framebuffer patch? In Clover I have only InjectATI. Perhaps I'm missing something here? The card is a Sapphire Tri-X 290X 4GB with stock OC with dual bios and active bios currently is UEFI.

The card is a Sapphire Tri-X 290X 4GB with stock OC with dual bios and active bios currently is UEFI. I thought there was a patch for this somewhere (atleast for the DP)? If I could patch frame buffers I'd already be patching and trying out, but unfortunately I don't have the time to learn it at the moment Isn't there something you can do in Clover, besides InjectATI? If I use InjectEDID, then it stays black all the time. Only thing I wish that would work is single monitor on DP, HDMI or DVI-D without that flickering If somebody got a patch or some Clover settings which work right, could that somebody please share it? I'd be eternal grateful! Kind Regards. Link to comment Share on other sites More sharing options...

stingray_454 Posted January 31, 2015 Share Posted January 31, 2015 If somebody got a patch or some Clover settings which work right, could that somebody please share it? I'd be eternal grateful! My 290X has had working DP with full acceleration and no flickering / issues since the first developer previews. I can't get it to work with Baladi but with the default framebuffers it works just fine (although if I connect another monitor I get flickering and similar issues). Works perfectly fine for HDMI as well, but not for DVI. I use the following settings: <key>Graphics</key> <dict> <key>Inject</key> <dict> <key>ATI</key> <false/> <key>Intel</key> <false/> <key>NVidia</key> <false/> </dict> <key>PatchVBios</key> <false/> <key>InjectEDID</key> <false/> </dict> 1 Link to comment Share on other sites More sharing options...

Awesome Donkey Posted February 1, 2015 Share Posted February 1, 2015 The one OS X loads on boot. If you're using a 290X without a specified controller and/or patched framebuffer in Clover AMD8000Controller.kext is the default one that gets loaded. You can see this for yourself by opening up System Information > Software > Extensions and clicking on AMD8000Controller. I don't know which framebuffer in AMD8000Controller.kext is being used though, maybe Baladi? This would be interesting to know actually. Link to comment Share on other sites More sharing options...

stingray_454 Posted February 1, 2015 Share Posted February 1, 2015 What is "the default framebuffers"? If you don't force it to use Baladi (AMD injection), it uses something else - it shows up in IOReg as "ATY,AMD,RadeonFramebuffer@0". It's some kind of default radeon framebuffer that is not Baladi. Running with that works a lot better than Baladi for me, and I still have full acceleration and QE/CI. Link to comment Share on other sites More sharing options...

If so, does it allow for more performance? Could I also use that patch for my Sapphire Tri-X R9 290X? If not, how do you exactly find out to patch it? @others: Unfortunately still the 'replug' bug on startup with the Sapphire Tri-X R9 290X 4GB. Don't have very much free time atm, so will take a bit longer to do a deep dive in the documentation and guides Link to comment Share on other sites More sharing options...
