durpflip Posted November 18, 2015 Share Posted November 18, 2015 nvidia drivers for OS X were mainly developped for reference models of the GTX 9xx cards. if you have an OEM version it might not work. it didn't work for my asus gtx 750 ti anyhow.

Can someone help me, please ? Thank you I attached here 2 images What else do i need to check or uncheck ? Thank you I am currently using that very same card on my home build (x99), the card works pretty good. I am using nvda_drv=1 to get the webdrivers to load, try it on. i did as you said but all i can get is 1920x1080 I also tried imac 14.2 and macpro 6 or something like that My gtx 980 ti is not recognized What else should I try ? Thanks Mac Pro 6.1 got me a black screen until i installed a fix mentioned at that other hackintosh forum/site, i don't recall it right now should post once i get home I have only HDMI on my 4K Samsung tv Could that be the problem, maybe ? Should i try with DP ( graphic card ) to HDMI ( tv ) ? Does it make a difference ? You know the cable might be an issue, depending on the cable version hdmi 1.2 or 1.3 you might find issues like lower supported resolution and lower base framerate, this is true specially with cheap cables. Try a DP cable and tell us how it goes. I am using a p2715q from dell, 4k @60hz via a single DP cable. Hope that info is useful to you. Link to comment Share on other sites More sharing options...

lemarqq Posted November 26, 2015 Author Share Posted November 26, 2015 Samsung UE40JU6550 is already compatible HDMI 2.0 I would try with DP ( graphic card ) to HDMI ( TV ) i don't know if it's working or not. @ river86, what's your monitor model ? Thank you Link to comment Share on other sites More sharing options...
durpflip Posted November 30, 2015 Share Posted November 30, 2015 if that doesn't work,you can always try setting your graphics resolution manually. so if your TV uses 4K you can type as a boot flag in the clover config ; Graphics Mode=3840x2160x32 Link to comment Share on other sites More sharing options...
bbeepp Posted December 7, 2015 Share Posted December 7, 2015 You should try Clover bootloader. I've just installed 980 Ti connected to two LCD's – one though DP and second one though DVI and it worked out of the box. Link to comment Share on other sites More sharing options...
jura_11 Posted December 13, 2015 Share Posted December 13, 2015 Hi there As above you should try Clover bootloader,can make yours life bit easier With those new drivers from Nvidia previously I've same issue,but in my case has been down to the I'm running extra GTX780 too in second PCIE slot. But to yours issue,please try this Fix: modify the AppleGraphicsDevicePolicy.kext Open Terminal Enter this command (it is one line) sudo nano /System/Library/Extensions/AppleGraphicsControl.kext/Contents/PlugIns/AppleGraphicsDevicePolicy.kext/Contents/Info.plist Arrow down to where you see <key>ConfigMap</key> For the iMac15,1 locate the board-id "Mac-42FD25EABCABB274" and change string below it from "Config2" to "none". For the MacPro6,1 you will do the same thing but for the board-id "Mac-F60DEB81FF30ACF6". For the iMac17,1 you'll have to see which board-id is declared in your config.plist SMBIOS: "Mac-B809C3757DA9BB8D" or "Mac-65CE76090165799A" or "Mac-DB15BD556843C820" and change the appropriate entry to "none". Save the file by pressing Ctrl+O, then enter. Exit by pressing Ctrl+X Rebuild the kernel cache using the following two commands in terminal: sudo kextcache -system-prelinked-kernel sudo kextcache -system-caches Reboot This is best option or solution for you there,happen to me same after I updated to 10.10.5 And I'm running EVGA GTX Titan X with Palit GTX 780 on my PC Hope this helps Thanks,Jura Link to comment Share on other sites More sharing options...
