Horrible colors on external monitor using macbook air(2012) with mini dp to hdmi

I have one of the new macbook airs (2012) hooked up to an external monitor (Dell SR2320L) using a mini display port to hdmi adapter.

The dsiplay shows up fine on the external monitor, except for the colors and contrast being terrible. Any color grey on a white background doesnt even seem to render. However if I look at that same image on the airs screen, I can see all of the grey colors perfectly. I have tested the hdmi cable and monitor on different computers and they work perfectly. I have tried three different adapters all with the same problems, leaving me to believe that there is something wrong with the macbook air itself and its ability to output a mini display port signal.

Does anyone know why I would be having a problem like this?

MacBook Air (13-inch, Mid 2012), Mac OS X (10.7.4)

I finally fixed my problem by getting rid of my tv and buying a completely different monitor. Now i can finally do 1080p without any color issue 😉

So does the 10.8.3 Update fix the problem or is it still there? I am dreading having to wait until 10.8.4.... or 10.9!

No idea, and I just arrived at work. When I get home, if nobody has replied I'll undo my changes, test it out, and let you know. If it fixes it I'll update my workaround blog post.

In my case the problem is solved with the 10.8.3 update!

I hope this fixes the issue. My question though, I used heycoach's fix by installing that profile tweak. I wonder if I need to uninstall it after the update to ensure its working properly?

Did anyone have to uninstall the fix first?

Confirmed, 10.8.3 solved the hdmi issue for me.

Unfortunatly the 10.8.3 did not solve my MDP to VGA issue. Still bad colours and almost no grey. Same problem with the MacMini. (But no problem when running Windows on same monitor.)

Update did not fix it for me with an external monitor using a display port, the edid override however did. Can not believe this isn't a standard check box in an advanced displays tab.

workaround on ireckon.net solved this bug for me on a retina macbook pro as well.

good job!

Actually it seems I skipped the last two steps of ireckon. I need to find the folder and move it over. Will update after I do.

I had the same issue. All I had to do to fix was push the RGB/COMP button on my monitor!
