Hi mjkelly93,

If you open your files in other programs (e.g. QuickTime or VLC) do they also display green?

Yes they do. In fact, the desktop background that is displayed on the screens has a greenish tint to it slightly.

I also noticed that when i go into the display properties and edit the color profiles, the greenish hue does not change at all when the other colors change.

Thanks for that. It does sound like either the Mac itself or the VGA to Composite adapters are at fault here. My advice would get in touch with Apple and see if they know of a solution.

I have someone bringing another macbook pro up so i can hook the same setup to her macbook and then ill know whether its the macbook or outside of the macbook.

Ok so i hooked up an older model macbook. Its like the 2009 model. I have the 2010 model. And i just simply hooked my mini display to vga into that macbooks mini display to vga, and guess what they are still green!?!

Ok so its either two different version/hardware macbook pros or its outside of the software and has to do with the wiring. Which is what i thought it was initially, the wiring. I tried TWO different avermedia quickplays, both put out green tint and a PC to component converter from radio shack that also put out green tint. I hooked those directly into the TVs and through the amplified splitter, both green.

The only wire i havent replaced is the mini display to VGA. But that wire puts out a perfectly crystal clear VGA signal with no green tint because i hooked it up to a VGA monitor that i had sitting around. So if the VGA signal coming out of the mini display to VGA wire is fine, and thats all that wire does, then what is the problem?



So in conclusion, i can rule out the macbook. Rule out the mini display to VGA since it puts out a crystal clear VGA signal. Rule out the avermedia quickplay unless 3 different component converters were broken. And rule out the TVs since it happens on all of them and on computer monitors. Its not the length either since i tried it on TVs through a 6 ft component cable and 50 ft component cable. So if its not the macbook, wires, or tvs... what else can it be?

If it's happening with all your software, then the common thing linking that would be the graphics card. If it's happening on two Macs, then it could be the graphics card drivers for these machines, so the fault could still lie with the Mac. Have you tried contacting Apple about this?

Here is what makes me believe its not the macbook, besides the fact that ive tried two of them now with similar results.

All the macbook needs to do here is output the VGA signal through the mini display to VGA adapter. And when i hook a monitor up to that cord through VGA, it looks great. No green at all. So the laptop is doing its job, right? Thats all it needs to do just that VGA output.

Then its up to the avermedia quickplay adapter to turn that into component signal and send it out through the component cables. I assumed it was the quickplay that was broken so i bought another one, same problem. Then i bought a PC to component converter, same problem. So three separate component upscalers have identical problem... Strange.

And then the only other variable is the component cables really. I'll run over to radio shack today and buy a brand new component cable and give that a whirl. Maybe all 10 of the component cables i bought are broken?

I wonder if the Mini DisplayPort signal just can't be converted to composite? Are the devices you are using simply adapters (i.e. just different plugs at each end) or actual signal converters?

The avermedia quickplay or the pc to component are both actual signal converters.

I discovered that if i turn the brightness on the TVs down to near nothing, the green goes away. The problem then becomes the videos are really dark. So i changed the gamma settings for that output to really high and they look ok, not the best but ok.

There are like waves rolling up and down on the screens though. Do you know what thats all about?

I'm afraid I'm all out of ideas about what could be causing this. Have you tried contacting Apple too?

I dont think its apple because two separate macbooks, of different versions and hardware, are causing it.

Also, i dont believe its the computer at all because its outputting the VGA signal just fine. I plugged it into a monitor and it looks good. And thats really all the macbook is supposed to do, right?

I was thinking more that they may be aware of something that we're not, e.g. that a Mini Display Port signal can't be converted to a composite signal (I'm just guessing here ;).
