Gtx 550 ti Artifacts After Web Drivers install

[shaggymen101]

Solved in Sierra 10.12.6!!

I have been using the post of jpalgron1

Is this:
" - Installation from usb drive:

Clover EFI (legacy mode) with nv_disable=1 & no Nvidia drivers injected (if not, hard reboot when injection):

Installation OK but screen is low resolution 1024x768

Next installing Clover EFI (legacy mode) on hard drive same params & change with Clover Configurator to iMac12.1

- first boot on HD:

OK in low résolution (Gforce GTX 550 is recognized, but no kext installed)

- post install:

Nvidia web drivers installed and activated
Changing EFI config.plist to "nv_disable=0"

- reboot:

OK:
screen recognized and hight resolution, BUT many bugs on the screen (a lot of black pixels on the desktop & windows)

So turning Off Nvidia web drivers in Configuration Panel, back to Apple nvidia drivers & changing EFI config.plist to "inject Nvidia drivers=yes" & always "nv_disable=0"

- reboot:

all is OK for now!
High resolution, no bugs, Geforce GTX 550 is recognized in system informations, Quartz & OpenGL working, Cuda working

Hope it will help you"

In my case:
1.- I used the kext "lilu" and "NvidiaFixUp" into clover/EFI/kext/others to get HD with glitches.
2.- Final config of config.plist: nv_disable=0, uncheck Nvidia web drivers and check inject Nvidia.

DESKTOP:

Intel DH67CL Sandy Bridge Chipset
Intel i7 2600k 3.40ghz
ASUS GTX 550 ti
SSD 250gb
CLOVER UEFI Boot

I'm running 10.10.5 with web drivers inject, using inject Nvidia and CmsVideoDxe-64 but I can't get the best resolution in clover and booting. This is the only issue with this graphic card right now.
Anybody know how to fix it?
