HOW TO GET VGA Video OUT Working if you have the Nvidia 8600M GT Video Card ONLY.

Using NVinstaller v.41 or NVinstaller v.52 (Select the Vanilla, and the 'M' or 'Go' Laptop options)

Tested with Mac OS X Leopard 10.5.3 and 10.5.2

1.Download and install PlistEditPro from here

2.Find the NVinject.kext (and/or) NVinjectGo.kext in SYSTEM/LIBRARY/EXTENSIONS , Right click it, show package content.

3.Find Info.plist then right-click -> open with -> PlistEditPro, the value to edit is in IOKitPersonalities -> NVinject -> entriesToAdd -> NVCAP) changing the NVCAP value with this value of a 15" MacBook Pro 8600M GT 256Mb:
040101010e0001000e0000000000010b00000000

4.save and repair permission (you can do that with DISK UTILITY on Applications/Utilities) and reboot with -v -f options



Flaviopiu and I got VGA out to work in EXTENDED mode great! (Both Internal and External). BUT, In MIRROR mode our internal laptop LCDs become black and we can only see the mouse pointer, while the external monitor displays properly. If anyone can help fix this problem or have any suggestions, please post. THANKS!

This Guide was made by Flaviopiu. Thanks!

same problem here with 8600m gt 512 mb

I tried it - all I get is a black screen. Tested with NV installer .52 edited plist in nvinject.kext there was no nvinjectgo.kext in the extension folders. I saved and repaired permissions.

I have tested with other nvcap values as well. I'm not sure what I am doing wrong! Everything else works good. I just want to work on my 24" screen!

My Rig consists of: Leo 10.5.3, video card 8600m GT, Inspiron 1520 Core2 Duo 2.2ghz.

I have it working without QE support.
Use this one: (dunno how to make it into numbers) BAAAAAAAAQAOAAAAAAAABwAAAAA=

YES! Finally got my lap working dual screen!
Thanks for the info dude!

Asus G1S-B1 Nvidia Geforce 8600M GT (Note LCD + HDMI + VGA + S-video) with iDeneb (10.5.4). LCD is working from getgo with NVinstaller 0.2.0, Dual working after inserting this NVCAP and 0407 as Card Model

Hope this helps other G1S owners

Awesome - Inspiron 1520 with dual screen working finally! Thanks! :-)

@hackbookpro - use an app like Plist edit pro to edit the Info.plist file - the string you are seeing is binary and you need an editor capable of reading/writing it going.

i can't get this to work. I have nvkush already installed though. Is this a problem?

Am running atkos 4i, dell 1720 10.5.4

@leokeren, what exactly did you do with those programs?? i have the same card looking to get my vga out working properly (without blank screen / crashing). how would i go about changing the rom revision? this is what i'm seeing:
Chipset Model: Graphics by NVIDIA
Type: Display
Bus: PCIe
PCIe Lane Width: x16
VRAM (Total): 512 MB
Vendor: NVIDIA (0x10de)
Device ID: 0x0407
Revision ID: 0x00a1
ROM Revision: NVinjectGo 0.2.0

NVinjectGo 0.2.0 = for laptop driver
for destop pc = nvinject only without " GO" or Efistudio for instal driver vga
for destop pc = nvdarwin

vga (rgb) depends on aplication or hardware for lcd monitor calibration= spyderpro

you can setting "rgb color" management with hardware spyderpro and edit with : CS2/CS3/CS4 or pixelmator

Guys - thanks so much!! Got this working on an Acer X233H 23" LCD using the 15" Macbook Pro NVCAP value placed inside NVkush.kext. My machine is a Vostro 1500 with 8600M GT 256M (0x0407, 0x10de).

Anyone know how to switch off the laptop display and have it just use the VGA monitor? Not that I hate multiple screen support, I just might want to at some point...

Thanks all!!

PS: I pulled my own NVCAP value (from the ROM, using NVFLASH on windows, and then NVCAP Maker on OSX) and inserted the resultant NVCAP string into the injector - it also worked.

Cant wait untill someone gets the 9600M GT 512 via internal LCD up and running!...Ive tried everything...black screen of nothing!

Kind of a double post, but FYI, the latest drivers from EVGA for their GTX 285 for Mac (see here) works better than that in 10.5.7. With added nvcap values (me using NVinject.kext, see here for details on editing), I now have all three of internal display, hdmi and vga working (of course at most two at a time) along with full res and qe/ci on 9800M GS (internal displ is 1680x1050). The nvcap values that work for me are

, i.e., outputs 2 through 5 on channel 1 (11110 = 1E) and output 1 on channel 2 (00001 = 01). Note that the default nvcap values for me were 03 and 0C respectively (NvInstaller v.52).

Mine doesn't support second display, cause then the system crashes on a black screen
And the pixels aren't that great, and QE cant be enabled.

For the card: NVIDIA 8600M GT - 512MB
- wich driver do i have to download ?
- What edit line do i have to add/mod ?
- bootlist ?

Greetings! Please reply!
