MithrilFox Posted August 24, 2009 Share Posted August 24, 2009 This is just to notify people of something that is not readily available on these forums: information about dual monitor support for the 4850. My system specs are also in my sig: Mac OS X Leopard 10.5.7 Asus P5K-V motherboard ATI Radeon HD 4850 512MB graphics card Dual monitor support simply by plugging in both monitors. If you have problems, try plugging one in, then the other, or try plugging in one monitor, then an adapter in the other monitor output, then unplug the adapter and plug in the second monitor. I can confirm once again: dual monitor support on my system with a single ATI Radeon HD 4850 graphics card is FULLY WORKING for me on my configuration.

mustiCas Posted August 26, 2009 Share Posted August 26, 2009 And are you having 2xDVI or 1xDVI+1xDVI->VGA? Link to comment https://www.insanelymac.com/forum/topic/181438-ati-radeon-hd-4850-dual-monitors-confirmed-working/#findComment-1236618 Share on other sites More sharing options...

MithrilFox Posted September 15, 2009 Author Share Posted September 15, 2009 I am connecting both monitors via DVI to DVI ports on the card. I also tried connecting one monitor via HDMI to a DVI port using an HDMI-to-DVI dongle, and it still worked nearly flawlessly. Issues I've encountered: * If I turn off the second monitor but leave it connected to the video card, my mouse cursor will randomly skip. That's it for now. As always, full-screen applications (like games) still have trouble with dual monitors. World of Warcraft will run flawlessly in full screen but will dominate the second monitor with blackness. This is common on both Windows and Mac machines and is a limitation of the video card's handling of full screen applications. I installed my card on a Leopard 10.5.7 system using ONLY the following packages: 1) 7_radeon_hd_48x0_drivers.pkg 2) Natit_no_powerplay_4800_4600.pkg 3) Natit.pkg 4) Patched framebuffers for 48x0 and 3870x2.pkg 5) QE_CI_Exotic_cards.pkg One or more of the packages may have been unnecessary, I have yet to test out which are essential. I did notice a jumping screen before installing the No_Powerplay package. Also, without the patched framebuffers package my computer would show just a "no signal" unless booted in Safe Mode (-x). I installed Mac OS X Leopard via a retail 10.5.0 disk using the Boot-132 method (vanilla/retail installation). I updated to 10.5.7 BEFORE installing anything pertaining to the card. I hope this is helpful.

SilentViper Posted April 13, 2010 Share Posted April 13, 2010 that's odd that you had to install that many extra packages to get it to work. i have a 4850 HD and it works dual monitor using Legacy4800controller.kext and GraphicsEnabler=Yes both in Leopard and Snow Leo Link to comment https://www.insanelymac.com/forum/topic/181438-ati-radeon-hd-4850-dual-monitors-confirmed-working/#findComment-1447970 Share on other sites More sharing options...
Hangten Posted April 14, 2010 Share Posted April 14, 2010 that's odd that you had to install that many extra packages to get it to work. i have a 4850 HD and it works dual monitor using Legacy4800controller.kext and GraphicsEnabler=Yes both in Leopard and Snow Leo Yup, same here dual DVI & DVI and VGA dongle & VGA dongle but only one HDMI ever sense 10.6.2 with no pkg installed. Wasn't running 10.6.0 very long so didn't play with it. I'm very happy with my Hackintosh so far and all eyecandy. Found another HD4850 on EBAY same make and model. Consider buying it for gaming in Crossfire in Windows. Will run just around a 5850 in performance if Fermi doesn't come around to Apple. VisionTek but no sign of it on the card!

I installed the 10.6.2 versions of ATI4800Controller (with the device id), ATIFramebuffer and ATISupport kexts using Kext Utility, and I have full resolution on my XFX 4850. However, I still don't have QE/CI. Did you install Legacy4800 to E/E or S/L/E?

Hangten Posted April 16, 2010 Share Posted April 16, 2010 @SilentViper Great to see it works either way almost SNAFU proof. I duno if 10.6.3 is actually benefitting me any still using the 10.6.2 Kext and my audio Digital out disappeared off my 889. Digital in is there go figure. Sleep is all messed up when i'm overclocked. So thats not good. if they release an X58 bios with a lot of support I'm switching brands.
