(10.7.1 update: no good) Getting the Dell u2211h to work properly on a 2010 Mac Mini

What you should probably do is right-click on the kexts for each and "Show package contents", that will let you get to the files inside. Info.plist is where the settings are held - so if you compare the Macbook-fixed version with the new one and copy the settings across that should do it.

Just tried that. There was one different value in the info.plist, called 'IOPCIMatch'. I changed it to the value that tomd25 had for it, which is '0x00000000&0x00000000' in stead of '0x000010de&0x0000ffff'.

I deleted the one that I had and replaced it with an updated version with changed values. After a restart, NVInject did start (which is good), but there are no visible changes. Still banded colors on the Macbook display and fortunately no pinstripes on the external display (which is good).

I really have no idea what I'm doing by changing values around. Is there someone around with a bit more expertise?

I did try and look at this a bit ago but I can't remember what I changed in the plist first time round - I'm sure it was something obvious like "Monitor1Dither" - and couldn't see any similar settings in this new NVInject. For some reason, my monitor is working fine with ML without NVInject so I don't want to risk playing around and breaking it, sorry!

PROBLEM SOLVED on NVidia cards (Sorry ATI folks, but maybe it'll give you something to work from)

How undo this tip. its seems my monitor has only IPS 6bit with something which "adds" more colours and its dell u2412m. I found way and looked better IPS panels what have 8bit with similar technique they sounds much better and i also readed they are better.

64bit Solution

Hi Guys,

I edit the 64bit NVInject file to work only with an external monitor. The only change I make is replacing the following code:
to

I tested it under 10.8 and it works well without any issues.

All the Best.

I just bought a Dell Ultrasharp U2412M to use with my Mid 2009 13" Macbook Pro (Nvidia 9400M) running 10.8.2. After a short time of use I noticed vertical lines in some colors that should have been solid.

I have now installed the NVinject kext from this tread. I used the one redlinner did some small modifications to. So far it works great!

I would just like to say a big THANK YOU to all in this tread for finding a fix for this issue.

Thank you (Dell U2412M + Macbook 2010)

Similarly to Zepman I just bought a Dell Ultrasharp U2412M to use with my 2010 Macbook Pro 15" with a Nvidia GeForce GT 330M 256 MB on 10.8 Mountain Lion. I had both pin-striping but also flashing on certain tones of colour, mainly variants of grey. After trawling through the internet to no avail I took it to the Apple Store where some textbook quoting goon told me it was the monitor, LUCKILY as I was about to give up all hope I found the 64bit version of Nvinject.ktext with redlinner's alteration and so far seems to have done the trick so BIG THANKS and hopefully anyone suffering the same issues will stumble across this...

It seems that this method doesn't work on 10.7 with ATI cards. By that I mean there was no evidence that NVinject was loading at boot (no console messages) and manually loading the kext didn't put the Dither keys in the registry.

Is there an analogous method for disabling dithering on ATI hardware?

NVInject is only for nVidia cards, unfortunately.

Yeah I realize that but this problem isn't isolated to just nVidia cards. How have people with ATI hardware turned off dithering?

Also, does anyone know what about NVinject makes it nVidia-specific?

Can someone please reupload the file from Redlinner above? The sendspace file is not available anymore...

Sure. Here you go. View attachment NVinject.zip

Bump.
I have the pinstripe issue on my 2011 Mini with the Radeon 6630M and the Dell S2340L. It's a subtle effect everywhere (not confined to certain shades) but is very noticeable on blues and oranges, like the blue menu highlight colour. The stripes are vertical.

I would lug my stuff to the Apple Store but the geniuses don't have very good eyesight. They didn't notice the image retention on my first rMBP.
