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 have exactly the same problem:

Laptop: MacBook Pro 13", Mid 2012

External Monitor: Samsung SyncMaster SA550 (HDMI input)

Mini DisplayPort to HDMI Adapter: Moshi Mini DP to HDMI Adapter with Audio Support (H1824ZM in the Apple Store)

Colors are generally washed out, very low contrast, very high brightness, some fonts are distorted.

Silly question I am sure, but how would I post an offical bug report?

Thanks, I didn't realize there was a way to file a bug report without going through the support channels.

Filed 🙂

I'm having the same issue, can't believe there is not a fix. Just spent over $3K on a MBP retina and it looks horrible on my external monitor, calibrated twice to no avail. I have an AOC monitor which worked perfectly with my older MBP.

Everything looks very washed out, like someone left on a greeny blue light on in there.

I used to work in Apple's Software Test dept years ago, they would have tested lots of external monitors - and decided not to fix it for the release.

Has anyone tried this specific fix:

Thanks.

BTW, some issue with MBA 11" 10.8.1

Doesn't help I'm afraid. Sounds promising on paper, but provides no cure in reality.

I played around with my monitor and settings a lot (for an hour) and it's now pretty good. Still - shouldn't have had to do that, but for anyone else, it's worth a lot of playing time.
