Hello

Recently my Macbook Pro's color became extemely saturated, and it isn't pretty.
When I connect the DVI converter cable thing the screen refreshes and it becomes normal, I can then remove the cable and it's ok. Of course I don't want to connect that cable every single time I boot and I don't want to bring this cable everywhere I go.

I think the MacBook is bugged or confused because the day before it went all issy, I tried to dual screen with a CRT, using that converter. For some reason it didn't work and i'm used to dual screen all the time (sometimes I work on my main screen and play WoW on the CRT). So I think those two events may be related.

Anyone got any ideas? Thanks

did you change your refresh rate in the display preferences? this might be the problem.

No I did not touch single thing setting-wise. I know there's a some keys that can be pressed to clear cache or something when you boot, maybe it could help? I don't the the actual keys though.

can you post a picture when it happens? heres the link to reset the SMC

I tried to do the SMC resetting but it didn't work, maybe I did it wrong, I did the following:
Remove the power cord
Remove the battery (no juice coming to the MBP)
Hold the Power Button for 5 secs
Reinsert the battery


Also I tried to take a picture when it's saturated (with Grab) and when it's not saturated, using my DVI converter thing to switch between them. However the 2 screenshots are identicals, if I am in "saturated mode" both pictures looks saturated and vice-versa when it is not saturated. I am really lost there =( My first Mac and I'm already having huge problems with it.

Have you checked your color settings within the system preferences? It's under Displays / Color. I'm pretty new to Mac myself and don't use an external monitor but it may be that it's switching display profiles on you when you plug in the external monitor. Worth a try.

Yeah I did, first thing I checked actually, then I tried to auto-calibrate, it's all the same settings as before, and when I insert the converter the settings dont changes but my screen is ok. I noticed that when I boot, the half second between the loading bar and the view of your desktop, you see your desktop iconless. During that half second my screen is okay, but then refreshes, I see my icons and all and it is saturated.

if none of these problems have no luck, i would make an appointment at an apple store to see if they can fix it by hooking up an external. i would bring the adapter with you if you decide to go to show proof.

My son's powerbook had what seems to be a similar issue, it turned out that his Logic Board went bad. Hope that is not your case as it was an expensive fix.
