slann303 Posted March 10, 2011 Share Posted March 10, 2011 Hi there, I want to report some of my findings regarding the Gigabyte Geforce 9800GT Silent Cell (1GB) in a dual monitor setting in a vanilla Snow Leopard 10.6.6 install (Motherboard: EP45-UD3P Rev. 1). I post this topic as a reply to the Topic "10.6.3 nvidia Blank Screen Issue", because as a new user I am not allowed to post a reply there. I hope this post is helpful for someone. My goal was to build a Hackintosh that functions as a working station and a HTPC (Plex). I have the computer hooked up in the office room of my house to a 24" monitor (DVI Cable) and to a LG HDTV in the living room (15m long HDMI cable). Until 10.6.1 I was able to run this setup without problems, they started though with the update to 10.6.2. After Chameleon has loaded I stuck with a blank screen on DVI and a blue screen on HDMI. I tried every method known to man, like using different nvenablers, adding device-ids to the grafipchscs-kexts, modifying the DSDT, etc., etc. I also tried using the old drivers from 10.6.1 (NVDANV50Hal, NVDAResman, GL/CL Frameworks) with several recent updates of Snow Leopard, but it just wouldn't work. The only solution I was able to pull off that satisfies me is as follows: The 24" monitor is connected via VGA cable. I get no restrictions on the resolution, so I can drive my pc-monitor with full HD (1920x1080). The TV is connected via the DVI port (I use a DVI to HDMI adapter) and no problems with resolution there either. In Snow Leopard I can mirror both panels. For Sound I use a Toslink cable that is connected to the optical out of the motherboard and to the optical in of my Receiver. For the Snow Leopard installation I used [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] with Chameleon RC5 and the sound kext for alc889a. In com.apple.Boot.plist of the Extra folder I use Graphicsenabler=yes and I have full acceleration. I do not use a DSDT because I am using MacBios from Cartri (http:/tinyurl.com/cartribios). I came up with this setup just recently, because some strange behavior made me believe, that VGA is not working right: When I hook up the 24"monitor only via VGA, I cannot set to resolution to full HD. I just found out recently, that when VGA and DVI outs of the GFX are connected, that the resolution of VGA goes up to full hd. Quote Link to comment Share on other sites More sharing options...
