Radeon HD 5870 / HD 5850

[seim]

Why my DisplayPort don't work yet?

I use 10.6.7 MBP kext and GE=No, the Ioreg showing ActiveFlags !=1 but the monitor still black (out of signal)

 

Same here.. Sapphire HD 5850 got it working with Chimera bootloader (included in [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url])

 

- Display Port recognizes that some thing was plugged in, but has a black screen

- DVI with a resolution above 1920x1080 is just working if you plug out the DVI cable and plug it back in after every boot :/

 

/Edit: this issue occurs just with 10.6.8 (in 10.6.7 or lower the Display Port works like a charm, copying the 10.6.7 kext file to 10.6.8 causes infinite booting with no result [-v shows a bunch of error messages due to the kext file])

Hi,

 

On the Lion GM, The Dvd Player and Geekbench crash with my 5850 Extreme.

Steam games does not start, but Starcraft II did (i have a full QE/CI).

 

I tried to turn GraphicEnabler to Yes but Lion crash on boot.

 

Any solution ?

 

Thanks !

I installed that and got a kernel panic. On booting I now have the error

ACPI_SMC_PlatformPlugin::start waitForService(resourceMatching( AppleIntelCPUPowerManagement) timed out

 

Then another kernel panic. My system will not boot, not in safe more or anything.

Don't work for me with the 11c40 update

Check my post out. I was able to get it working by installing just the ATI kexts from 11c37.

I tried your kext, but graphicsEnabler, Dvd Player et Geekbench still don't work.

Hello everyone changed one of my two displays to a bigger one. Went from 22" to 27" but I don't get signal now. Everything seems fine during boot both displays are on, but the bigger one goes dark saying "no signal" at the login window. If at that point I unplug and plug the DVI cable back in the display works fine. I tried to google around but could not figure it out any advice? Would I fix it if I would buy a display port cable?

I am on 10.7.3 and with a Ati Sapphire 5870.

Thanks

I too am running 10.7.3 and have had issues with my XFX 5870 working with triple head all the way back to 10.6. I have 3 displays. Two displays only have HDMI connections and the third is DVI. The 2 HDMI displays are hooked up to HDMI, DP (through active DP->HDMI adapter) and DVI on the third.

 

On some boots all 3 displays work. Most of the time though, only 2 displays are enabled. When this occurs, System Profiler shows 3 displays connected and correctly identifies the third display. I have tried changing resolution to trigger the display to come back, with no luck. I have tried disconnecting and reconnecting the cable, in vain. I have removed all connecters from the video card and replaced them in different orders, only to fail.

 

One thing I have noticed is, when I do disconnect cables from the video card, only the first 2 displays I connect show a picture, no matter which connection it is. Order only matters.

 

Someone, please rescue me from this grotesque inconvenience.

 

Also, does anyone know why the OS stutters whenever a connected display is turned off? This has always happened to me on every system I have install Mac OS X on all the way back to Leopard. This is especially annoying!

Hello together, I'm also suffering from the 2 of 3 display problem. Before last week i had a 5870 eyefinity 6 witch worked fine, but now i changed to a Powercolor 5870 PSD 1024MB and always one display is not working correct with 10.7.3. Does somebody have a tip for me ?!? I'm using 2xDVI 1xDP.
