    Dual monitor (vga & hdmi)

    Hi guys, I am currently running ML 10.8.3 in a machine with the following specs: - Gigabyte gtx 670 - Gigabyte z77x-udh5 - core i5 3570k For the past half year I have used a single monitor setup using a VGA (only) monitor connected to the DVI-I connector of the gtx 670. Recently I bought a second monitor and my intention is to connect both to the graphic card. Hence, I connected the new monitor to the HDMI connector of the graphic card. The problem is that when I boot into OSX with both monitors connected the VGA->DVI-I one goes to sleep (after the apple logo) while the HDMI returns a blank/gray screen, my impression is that OSX freezes completely. When I boot with only one of the monitors connected, everything goes well. If i boot with only one monitor connected and connect the second one after the boot the OSX will freeze and force me into a hard-reboot. Moreover, when I boot into Windows 7 everything works fine, so I suspect is possible to use VGA+HDMI. I have google it and some people ( that had the some problem with the gtx 560) suggest adding to the chameleon plist, it didn't work for me. Do you guys have any suggestions ? thanks Flavio

    GTX 670 issue

    It's been a bit since I've been hackintoshing. I have this build working with Yosemite (10.10.4) but can't seem to get my GTX670 to work with 10.10.11. I'm booting with the latest version of clover with no graphics injection. I have monitors connected to: HDMI, DVI, and DisplayPort. When booting verbose (-v) I can see where the Nvidia drivers are loaded similarly to Yosemite but then my screen goes blank. I can see my hack show up on the network from other computers. Booting with nv_disable=1 works for me. Any ideas?

  3. Hi All After days trying finally I got the hdmi working but not the dvi, but my monitor is connected to dvi and the tv is connected to hdmi please help me, how to activate the dvi. Attached my efi folder EFI.zip
  4. Hi there, I've just recently assembled myself a new Mountain Lion Hackintosh, and almost everything is working perfect, except OS X won't seem to allow me to use more than two monitors. My build contains Intel Core i7 I7-3770K 8 MB Gigabyte GA-Z77X-UD3H Gigabyte GTX 670 WindForce OC And on top of that, I have three monitors. The GTX 670 has 4 outputs: 2 x DVI, 1 x DisplayPort and 1 x HDMI Currently, I have two monitors connected, both using DVI. When I connect a third monitor using the DisplayPort, one of my DVI monitors simply goes black, and I don't know what to do about it or where to even start. The GTX 670 worked right ouf of the box with full acceleration after installation. Any ideas on how to make GTX 670 detect and use the three monitors simultaneously? If that's not possible, I'd alternatively just like to be able to connect the third monitor to the integrated HD4000 graphics card. I have tried this, but OS X seems to completely ignore the HD4000, even if I disconnect the other monitors. I use GraphicsEnabler=No and iMac 12,2 system definition, because I get a kernel panic with Mac Pro 5,1. Any help is appreciated! :-) If you need any additional information, just ask.
  5. I don't do any games, 3D modeling or CUDA. So I don't care about 3D performance. What I'm looking for is the fastest 2D card. Basically I want all my window changes drawn as fast as possible, same with moving windows. Still I got a GTX670 because I thought with it's PCIe 3.0 and 256bit GDDR5 memory interface it should be very fast at 2D too. Didn't find any OSX 2D benchmark software. For Windows there is 2Dbench.exe from TomsHardware.com. So I run it under Fusion 5 and got really surprised. The HD4000 got more then double the 2D performance to the expensive GTX670. Also tested a GT640, it's close to the GTX670 and but also half the 2D performance of the HD4000. All test run fullscreen 2560x1600, OSX 10.8.2., Fusion 5.0.1, on a Dell 3011, 30" screen connected with DP. HD4000 - 1030 GT640 - 510 GTX670 - 473 (yes higher numbers are faster ...) This results say that any PCIe graphic card is much slower then the integrated HD4000 in 2D. And all the normal daily stuff, like browsing the web, email, movies etc. is 2D. Is there any OSX 2D benchmark software to confirm this ? GTX670-2560x1600.tiff GT640-2560x1600.tiff HD4000-2560x1600.tiff
