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

For what it's worth, I received a Radar reply today for the HDMI display bug that I filed on August 27th, stating that it's a duplicate of another earlier bug.

So someone in the Apple development group is looking at this.

What's a 'radar reply'? Never heard of them?? I filed a bug report with Apple in early August, possibly late July and haven't had any response. What did you do to get a reply?

I'm part of the developer program.

interesting - I am a registered Apple Developer. No matter, as long as Apple is working onthe problem and we will see a solution soon [I HOPE!!]

thanks for clarifying

I'm having the exact same problem. I have a mid-2012 maxed out macbook air. I bought the moshi mini displayport to hdmi adapter and the display on my TV looks terrible: washed out grays, fuzzy text, way too bright and contrasty. When I connect my old white macbook with a mini-dvi to hdmi adaptor (same hdmi cable) it looks perfect. Crisp text, nice colors.

Any answers yet?

From www.macnn.com, posted 14Sep "Apple pushes out new 10.8.2 build, release eminent" (sic!)

... The accompanying Read Me file asks developers to focus on the same areas as the previous build, primarily graphics performance and quality as well as Image and Media importing, editing and viewing. The update is expected to be a rare "point" release that adds features in addition to fixing issues. The final 10.8.2 is expected to add phone number and Apple ID syncing to iMessage and FaceTime, as well as implement system-wide Facebook integration for users of the social service.

so PERHAPS the "graphics performance and quality" may solve the HDMI garbage output issue. Until then, I would suggest anyone who has yet to post an official bug report do so as per the instructions on the previous page of this thread.

Goto http://www.apple.com/feedback/macosx.html and post a bug report. The more people that do so, the more likely we get a solution from Apple!

I really hope they fix it. It's starting to feel like this issue has ended up in a support black hole.

So is there any way (before the bug is fixed) to connect the 2012 MBA to a 1080p TV that only has HDMI?

For example, does Mini-DP to DVI adapter combined with DVI-HDMI cable work ?

Thanks in advance.

From other users' experience I'm pretty sure this fix will work - although you will lose any sound that may be transmitted va the HDMI.

Hi,

Facing the same colors issue with MBA. MBA running OSX 10.7.4 connected via MiniDisplay/ HDMI to Philips 23" 248C3LHSW model monitor.

Filled the feedback details to Apple.

Hi,

I just got a reply from the Apple engineers:

"Apple has received reports of this behavior and is investigating those reports. Apple recommends staying up to date with the latest Firmware and Software for your Apple product using Software Updates."

Apparently, the engineer dealing with the issue has the same problem with his macbook. Well, I guess we should wait and hope it will not take ages.

At last... Good to hear!! Let see...

I do a fair amount of business with Apple and bitched to my business services team in SF about it the other day (also forwarded this thread to them...). Not sure if that's what raised the flag finally, but it probably didn't hurt...

10.8.2 did not fix it! 😟

I confirm 10.8.2 did not fix the same issue with my rMBP.

Neither did the rMBP EFI Update 1.0 released today.
