Why does my powerbook screen look inverted(256 colors)

when I powered off my PB after it locked up
and re started it goes to the mac OS blue screen and starts
loading normally,then all of a sudden it goes goes grey and inverts
all images loading on the desktop. When I check the displays
screen under system pref. it had my colors listed at 256. So
I switch it to millions and it still did not return to full color.
I suspect I'm in some type of safe mode.
Can someone tell me how to return to my full color resolution
screen. thanks in advance

Open the Universal Access pane of System Preferences, and then on the Seeing tab. Push the button by Black on White to return to full color. You can also toggle this setting by pushing the Option, Control, Command, and 8 keys simultaneously.

  • Why does new 5s screen look like the old 4?

    We just bought and backed up two new 5s replacing iphone 4. Why does one new 5s screen look like the old 4 iphone. One phone shows new version, one is still old. I have downloaded and backed up twice, same thing happens. Used icloud to backup.

    Sure, here's two photos, LP5 is the old screen style, NP5 is the correct screen. Note the differences?

  • Why does my powerbook screen go negative, then rain pixels

    So this has been happening for a bit now. 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. 
    Has anyone ran into this issue before, or know someone who has? 
    I feel as though he may have himself a very portable desktop now.

    Boot in safe mode and try to recreate the issue and report here.

  • Why does my Finder screen look like this?

    When I open Finder by double-clicking on the "Macintosh HD" icon or by clicking the Finder icon on the Dock, it comes up with the left pane being much larger than it needs to be. I don't recall it doing this when I first got the computer, so I'm thinking that I've done something to mess it up. Here's a screenshot so you know what I'm talking about:
    http://www.frenzied.us/~mattg/finder.jpg
    So every time I use Finder, I have to drag that middle bar over to the left some so that I can actually see more files & folders on the right side. Help!
    Mac mini 1.25GHz   Mac OS X (10.4.7)  

    I also used this method. Sometimes though I add one step - I open a new finder window, click one of the icons in the window (once) and then close the window with an apple-w or the red button. Usually does the trick.

    I've tried contacting Adobe, but they're ways of contacting them are a pain in the ***. The chat doesn't work and I'm on hold forever when I call.

  • How does the Touch screen look in direct / indirect sunlight?

    Was sitting on the LIRR heading home when I had this thought... after watching some guy playing with his PSP, as the sun was falling on his screen.... hhmmmm, I wondered how my Touch, which is now enroute from Anchorage, is going to handle the sunlight hitting it? Will I be able to watch my movies/tv shows without problem? How does the Touches screen look when sunlight hits it. I realize that sunlight hitting the screen is not an optimal viewing situation, but couldn't help but think how it would look. Those that are lucky to have one.... how does it handle sunlight?

    readable, but not great. I had it out in bright Ozzie sunshine and I could use it, but I wouldn't watch a movie on it.

  • Why does my lock screen glow green?

    Why does my lock screen glow green? It does it quite often, no affects on  the phone.

    Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new).  Try each of these in order until the issue is resolved.

  • Why does my RAW image look grainy when I export it in to Photoshop CC from Lightroom for editing?

    Why does my RAW image look grainy when I export it in to Photoshop CC from Lightroom for editing?
    Checked LR's setting for Ps export and they haven't changed since it was OK a few days ago? It is OK if you zoom in but in 'fit page' it looks terrible!

    I have exactly the same problem and it has got worse today as the photos also now open in smaller windows for some reason

  • Why does my Imac screen slide and I lose my screen?  It goes back to my desktop.  Then sometimes my screen goes to full screen and I don't know how to get out of it.

    Why does my Imac screen slide and I lose my screen ~ It goes back to my desktop.
    Then sometimes my screen goes to full screen without me doing any commands, and I don't know how to get out of it without going to force quit and starting all over. 

    Hi,
    When it goes full screen try moving the mouse up to top right of scren & see if there a double diagonal Arrow to click on.
    On the other see if it's the silly implentation of Spaces/Mission Control/Expose in ML...

  • Why does my lock screen settings page look different?

    I just got my S4 mini and I am trying to set up lock screen widgets but according to all the tutorials, my options under Settings > Lock Screen looks different. I do not have the "Multiple Widgets" option. I DO have the "Favorite Apps or Camera" option that needs to be switched on or off, BUT it's grayed out! I just did the updates so that can't be it. What do I do??

    The options are dependent/limited based on which lock screen you choose.  For example, if you choose a lock screen of Swipe, you'll see a choice for the Multiple Widgets that you were originally asking about.  If you choose a lock screen of Pattern or PIN, the Multiple Widget option (along with several others) isn't available with those particular lock screens.
