Hi guys.

I'm sure this is a pretty old problem but I couldn't find a fix after looking for about an hour here and elsewhere:

I need to hook up a second display to my XFX 6850 card and it's not supporting the second display. If I plug into the top HDMI (with the top DVI port also in use) the OS will recognize that a second display is plugged in but only black will be shown on that second display. So, in fact, only the top DVI port is working at this time.

I saw a few kext ideas etc but I'm not sure they apply anymore. Anyone have an ideas? I'm running this under but can use 10.8 if required.

Thanks in advance.

I thought I read some info on how to add the card personality to the kext but it's unclear as to which kext version they're modding and if it's this card or another. Help?

I have a Gigabyte Radeon HD 6850. I use "AtiPorts=4" in the /Extra/org.chameleon.Boot.plst file.

<key>AtiPorts</key>
<string>4</string> <------- or however many ports your card has

Try booting from Chimera with "AtiPorts=4" then modifying the /Extra/org.chameleon.Boot.plst file with TextEdit.

Thanks! I'll give that a try.
