Ratz1 Posted March 18, 2010 Share Posted March 18, 2010 So I just got my new Mobo working with my MSI Radeon HD4850 512MB graphics card. It has 2 DVI's and I'm using DVI to VGA converters to use 2 CRT's, but I have no display options to turn off mirroring. I haven't been able to find anything in my searches, has anyone figured this out? I'm a little uneasy about going around testing different Kext's and Boot.plist's because I don't want to ruin what I have, my roommate has done that with his HD4870 and can't get it to work anymore. All I've done is use the Kakewalk ATI installer and what I found on the Wiki, the radeon hd 48x0 drivers, patched frame buffers, and QE CL Exotic installers, I have full resolutions and everything is working great, but I just can't seem to turn off mirroring....

SleepingPanda Posted March 25, 2010 Share Posted March 25, 2010 I'm having the same problem with my XFX 4870 1GB. 2 CRTs via DVI to VGA adapters and no Extended Desktop, only Mirroring. What's strange is my card was natively supported without having to configure anything. I didn't have to mess with any kexts as qe/ci was working 'out of the box'. And my card shows up correctly in system profiler. It just doesn't show that I have a 2nd display.
