OS X :: Screen Colors Shifted To X Ray / Negative Like?
Jun 23, 2008
It seems that in his nasty habit of taking naps while resting a body part on the keyboard, he has managed to press some obscure key combination that has inverted the colors on my screen (like a color photograph negative). I've searched everywhere to try to revert this, but had no luck so far. When I restart, and/or log out and back in again, the screen is normal during the booting sequence till I choose the account I want to log in with, then it immediatly goes into "x-ray" mode. If I choose another account, it will boot and log in with no screen problem whatsoever. So this must be either a preference option has been changed via keyboard command or the account is corrupted. Right?

it makes everything on the screen a negative. I like to use it for design ideas, and screenshots sometimes. Hit Ctrl+Option+Command+8 and see the madness.

My screen suddenly went xray/negative/black & white. Everything on the internet says to hit "control+option+command+8," but that doesn't fix it--the screen just goes white. Going to system preference and adjusting the universal access items doesn't help either.

I saw this little "trick" command, control, alt, 8 in a Mac article a few weeks ago. It was nothing more than a cool, little screen alteration that makes the screen go negative. I tried it after first getting my Mac. Just this past week, I tried to do it again and it is not working. Not that it is a serious issue however it is more of a curiousity why it stopped. Did some application I installed on my machine cause this feature to halt? Just curious if anyone has the answer. I tried disabling Shades, Growl and even turned off my power settings to see if that was interfering.

My room mate turns on his computer and the screen is fine. After about 15 miuntes the screen image basically goes negative for a minute or so. After that little pixels begin to rain down until the entire screen is pixelated.  When it is pixelated I can use an external monitor to view my desktop perfectly, which eliminates the graphics card as the issue in my opinion. Â

I have a late 2006 Macbook, and my dad has an early 2009 Macbook. I was comparing the two today and noticed that there was a significant difference between their LCDs. My dad's Macbook has a lighter, more normal display. While mine has a yellow tint to it and is darker. Both computers were on the same display profiles and both had the same brightness set.
Is this just how LCDs are as they age? Or is mine really not supposed to have that yellow tint? The new Macbook is on the right in the pic.

Today while working with an InDesign document it crashed and I had to reboot the hard way. After starting up again the colors of my screen was all twisted and strange. It's like a very high contrast/bad resolution. Except for the screen-issue the machine works fine. I tried changing setting in preferences/display (no. of colors, resolution and color profiles) didn't work. I then tried resetting the PRAM, which didn't have any effect either. I tried creating a new user and logging into the account - and it looked fine? It's probably just a pref-file that need rebuilding or the like, but I have no clue as to where that might be. I work on a G5 PowerMac with Tiger on it.

In display in system preferences there is a tab with "Millions," "Thousands," and "256" colors,but 256 colors is dimmed. How do you set your MAC display to use 256 colors so I can play an older game?

Everything is very difficult right now as my iMac has turned into a print by that "15 minutes of fame" bloke. The screen resolution has gone completely strange and everything looks really blocky and boldly coloured... but only for one user. If I log in under my wife's account everything is fine. I've been through all the system settings a dozen times, and tried changing the resolution back to max and colours back to millions, but nothing helps. Googling for the problem doesn't find anything either. I've even tried a time machine restore of my area to earlier in the day, but that doesn't seem to help (although it won't let me restore my home directory, as the restore button is grayed out). When I switch users, the resolution jumps back to normal for a fraction of a second... just before I switch away to another user. A kind of "here's what you could have won" teaser. Likewise, when I switch back, all looks OK for a split second.

1. Today, I turned on my MacBook running 10.5.7 bought in the Summer of 2006 and the colors were washed out/faded. They were noticeably more bluish-purple. This is the third time it happened over the past year, so it is incredibly hard to replicate for a genius. A restart fixed the issue. I did not mess with the color schemes (I actually don't even know how to use them), nor have I dropped my laptop in the past three years I have owned it. Anyone know what is the issue here? I'm pretty sure it's hardware-related. I am concerned because my AppleCare is expiring this coming September, and I don't know how to replicate the problem.
2. Also, after a good period of nonuse, one-fourth of my screen (the lower left corner) is noticeably "darker" after I turn it on. The area goes back to its correct brightness after 10-15 minutes, like the screen has to warm up first. I've had this problem since I first purchased the unit but this dark spot has definitely gotten bigger. Is this normal for a laptop?
3. Coconut battery says that I have only gone through 4 battery cycles. I've calibrated the battery and the program still says the same thing. The battery I replaced quite a while ago did not have this problem.

I have a 3.06 GHz, 4 GB, iMac running 10.6.1. and I have a weird problem: while I was running Windows 7 under Boot Camp, during a simple task, my screen suddenly turned a solid shade of gray. Having no other option, I held the power button, turned off the computer, and turned it back on.
When I booted back to OS X, it happened again immediately upon opening iTunes. This time the color was solid black. Concerned, I turned off the computer, waited a moment and booted it back up in Safe Mode, where I currently have no problems whatsoever. From Safe Mode I repaired my disk permissions, cleared my caches, and zapped the PRAM while restarting my computer back into normal mode. Unfortunately the problem persists, this time my screen turning a solid shade of dark purple.
I'm going to call Apple Care in the morning, but has anyone heard of an issue like this? I searched the forums for a solution, but wasn't sure what terms to search for.

Well today I was using the screen capture (in Quicktime X) on the 9600M GT and the result every time was that the colour was all screwed (see in attachment) I tried it on the 9400M and the screen capture was fine. I'm wondering if this is specifically a hardware issue or something that software may be able to fix. Currently, I have not ran into any other problems with the 9600M GT. Is this happening to anyone else, or can anyone else test it out to see if it happens to them?

My tibook .867Ghz was working fine this morning, but now when I restarted it this afternoon, the colors are all off (lots of green and rapidly vibrating pixels in background). The computer works, I can run programs and so forth. There are no changes to the displays settings, still 1280x854 and colors "millions". When I switch to thousand or 256 colors there is no significant change.

while i am using my macbook the screen will suddenly go blue and flash between different blue colors like it is trying to work. sometimes it comes back on but most of the time it stays like that. I have to force shut down with the button and then restart...about half the time it is still flashing blue after the restart and if it does work, it goes blue eventually.
dont know if its a problem with the screen or what because the computer continues to work...if there is a movie on, you can here it in the background and the screen just flashes.

for only one user on the system, the colour scheme has gone negative. Backgrounds, files, programs, etc. have all been affected. I can't find anywhere that would have this effect - it's not in system preferences or anything like. How can I fix this?

I am looking for a slide and negative scanner. All of the ones that I have found in the under $1000 price range say they are compatible with some variety of Windows.
Which is great for them.
But what about Mac? I don't want to spend the money just to find that I can't use the thing.
Any recommendations?

Time Machine told me I had to erase the files on my external hard drive and I had to put them in trash, so, I did and it is deleting 55,000 files (Old Time Machine backup) and now it's going into negative numbers? Is there another way I can delete the back up?

I have a MacBook and the display is much different and an option that i cannot find on the settings. The display on my screen has a negative view to it. As if you were looking at a picture film. I have all the current updates on it, the hard drive is only months old. I don't know what is wrong with it, if a setting what changed that I can't find or if my computer is messing up?

Can someone recommend me a decent negative scanner? I want to digitise all my old photo negatives in a format good enough to keep in iPhoto and upload to Flickr. I'm not interested in ultra professional resolution, but something in the region of 5MP would be good enough.
I've read that Veho are going to be updating their scanner hardware to work with the Mac, but I've heard some stories about the quality being awful. I wish someone would actually upload some of the results so we could decide for ourselves, but it has put me off.
I don't want to spend a fortune, but I am willing to spend a decent amount of money (low hundreds of ���, NOT thousands!!) to get what I want.
