GTX 650 framebuffer patch - hdmi not working

[Spamm3r]

Hi guys, i have some issues with my gtx 650. Some apps and games are crashing and my friend told me to change port from dvi to hdmi and this will fix the issues, now i get black screen after os x launch (before logging screen). I think that this is issue with framebuffer, i have new driver installed and everything properly configured. I only need patch for framebuffer, i wont use dvi port again (i need some apps which are crashing now).

 

#edit# without driver hdmi works but lagging and flickering.

#edit 2# if you know what there address means just help me:

I only need patch for framebuffer  ? what framebuffer ?  

[Spamm3r]

if you know how to fix it other way just tell me - no dvi, no more

[C.Frio]

hi..

 

just to say I have 2 gtx 650 and they work oob , only injecting nvidia at clover options  ..one on DVI other on HDMI...

I am sure if you research through the forums and or google you will findout that framebuffer patches pertain to ATI(AMD) cards not Nvidia, you also haven't given any information on your other system specs and boot loader you are using

[Spamm3r]

so im using clover

hackintosh specs:

intel core 2 quad

motherboard giabyte g33m-s2

without drivers hdmi works but with drivers monitor cant find source

GTX 650 does not need web drivers, it only need injection>Nvidia>True in clover config

[Spamm3r]

And if this won't fix my issues with hdmi so what I am supposed to do?

[cecekpawon]

"Inject>Nvidia>True" only work with 1st port, otherwise you'll see black screen.

 

- Boot with "nv_disable=1"

- Create efi strings, eg: port 2

<key>PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)</key><dict>
  ...
  <key>@2,AAPL,boot-display</key>
  <string>0x00000001</string>
  ...
</dict>

Here's how

[Spamm3r]

eee nope, not working with Inject Nvidia = false and efi string.

UPDATE: here you are:

- ioreg

- dsdt

- config.plist after string injection

- config.plist before string injection

- device properties xml and hex (after patching @0 to @2)

config_all.zip

[cecekpawon]

You only have 2 framebuffer (0 & 1), so you need add 1 more. And leave inject Nvidia to false.

 

<key>@2,compatible</key>
<string>NVDA,NVMac</string>
...
<key>@2,name</key>
<string>NVDA,Display-C</string>

goodluck

[Spamm3r]

I only have Display-A and Display-B. Shall i add a new key + string?

 

#UPDATE1# so have i added new key and string

#UPDATE2# not working again, still black screen, after boot with hdmi, im attaching new xml with: 

<key>@2,name</key>
<string>NVDA,Display-C</string> 

 and clover config plist (with new hex).

[cecekpawon]

Hello, missing this properties at @2

 

<key>@2,compatible</key>
<string>NVDA,NVMac</string>

Hope this one can solve your problem

so its not working, after boot and before logging screen computer reboot (bar going to half and then reboot). Changing to dvi -> works. My gtx 650 has: 2x dvi, 1x vga,1 x hdmi. Maybe could you help with teamviewer @cecekpawon?

[Spamm3r]

bump... someone something?

[toekimarks]

You need to boot with nvda_drv=1. No need to patch anything.

[Spamm3r]

man its not working?

[toekimarks]

Try to install the latest nvidia cuda and web driver and boot with nvda_drv=1 and GraphicsEnabler=No. This worked for me with both mavericks and yosemite, so I'm sure it will for you.

[Spamm3r]

not works for me

[toekimarks]

I've got both yosemite and mavericks working this way with also a core 2 quad processor. I would suggest trying a fresh install. When you boot your install usb with nvda_drv=1 and Ge=no you directly should get the right resolution with hdmi. So try If you can reach the installer with the right resolution. If so, installing will solve your problem.

 

What brand is your gtx650? Mine is an MSI

[Spamm3r]

mine is gigabyte, i was trying but nothing works

[toekimarks]

Did you use clover or chameleon? Clover doesn't work for me either with the nvidia injection. If you're using chameleon I would say you tried everything you can.

[Spamm3r]

i have clover

[toekimarks]

Then you should try chameleon.
