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

Same problem. Mac Air mid 11, belkin thunderbolt-hdmi cable, samsung lcd hd display, bad image.

I've send a feedback to apple, but they just replied "thanks for feedback" without any obligations...

I don't have a DVI input in the display. What to do? (I've read almost all discussion)

Someone told about success using parallels, but i've tried - no result (

@pdashko: The only solution you have, I think, is to go back to Lion and as we all are, wait until Apple resolves this issue...

@pdashko buy a thunderbolt to DVI adaptor and an DVI to HDMI cable. This works, including Mountain Lion 1.8.*.

thanks!

thunderbolt-dvi should be male-male or there is no difference of the dvi female position?

update: this will not work for OSX 10.7.5 ??

@pdashko

I can't imagine the male / female position of the DVI should matter.

Re: Parallels, this won't help as OSX is still the underlying operating system.

But log out of OSX and log into Windows using bootcamp and it should work fine. Not that this is necessarily much help of course as I'm sure using OSX was the objective having made a mac purcahse..

thanks. so the main question is - will dvi solution work on osx 10 7 5 ?

omg, i spent 55 euro on these cables but with no success.

mac air mid 11

os x 10.7.5

samsung UE22ES5000WXXN lcd display

will test on other displays and macs but don't beleive in any other result (((

Hi,

I bought a mini display port to DVI adapter, then connected this to a DVI to HDMI adapter and then HDMI cable to my screen and guess what... it doesn't work. The Macbook does not see the external screen at all with this set up. I need to test the adapters with a PC at work to establish whether they are working all right, but I am really becoming pessimistic about all this. Has anyone got an idea how to make this work using the adapters and cables mentioned above? (I don't care about the sound coming through to the screen)

Thank you in advance.

in my case first time it was also no signal. Try to reboot display and reconnect cable several times.

I've got good colors using mini display port to DVI adaptor.

However, here's the kicker. If you ever want to watch HD movies or TV on your external monitor, it won't work, because DVI doesn't support HDCP which is the content protection built into HDMI and that all computers are required to support. PS: I haven't tried this but have seen it happen in other situations.

lukaso, what about text? is the font sharp enough?

pdashko, do you mean on the dvi version? Everything's perfectly fine, except my concern about playing HD movies, which I haven't tried to do yet.

On the HDMI version, it's all bad...though fonts that aren't washed out are probably sharp enough.

Update:

At home I tried connect the Macbook via mini display port to DVI adapter --> DVI to HDMI adapter --> HDMI cable connected to my monitor which only has HDMI inputs. No signal, the monitor was not detected. Then I tested the DVI adapter at work with two different monitors (Dell and Samsung) connecting it to them with a simple DVI cable. It didn't work - no signal in both cases.  Now the really frustrating part - my colleague connected his older white Macbook 13" to those monitors using the same adapter and cable and it worked perfectly. Therefore, my adapter works, it is just the Macbook that has a problem. It is really annoying because it worked via DVI before when I brought my Macbook to an Apple Service Provider and we tested it - I suspect that it is the result of the update to 10.8.2 which I did in between those two tests.

I was hoping that since via HDMI the colours are terrible and some of you reported that connecting through DVI works fine, I could use DVI instead and in the worst case scenario just buy a screen that has DVI input, but now for some reason the Macbook does not detect any screens via DVI.

Would you have any suggestions on how to get the Macbook to detect an external screen via DVI adapter? I would really appreciate if someone could give me a solution to this.

I tried pressing alt/option key in 'Displays' to make the Detect displays button visible. Pressed it, the screen on the macbook went blue for a second, but then nothing happens, the external screen gets no signal. I also tried numerous times unplugging the screen from the power supply, from macbook, then replugging all in. None of that helped.

I should add that:

- the Macbook also stopped detecting external displays via mini display port to VGA adapter (it worked before the update);

- detection of my screen still works using my previous mini display port to HDMI adapter, but, obviously with the same washed out colours.

In sum, three months of battle to get the Macbook to work correctly with an external screen - still no luck. What a piece of junk!

Thanks.

I've also had no luck with an HDMI to DVI adapter. When I used it, I'd have the image flash on the screen for about 2 seconds before disappearing.

I've had luck with the VGA adapter (colours look fine). I also have a straight Mini DisplayPort to DVI cable on order due to be delivered today. I'll let you know how I get on with that.

A further observation...

The MBA I purchased in early July has this problem.

However, a brand new MBA I purchased last week does not. It works fine on the same monitor with the same config - MiniDisplayport to DVI adaptor connected to a Male DVI to Male HDMI cable.

(For the record, these are corporate purchases, so no, I do not carry TWO Airs around with me...)

Consequently, this appears to be a hardware issue with a particular vintage of system. Recall anyone?
