On the startup screen color negative


Hi, It's an unusual problem but I don't thinks it's hardware. Most likely a corrupted preference file. Remember the screen just displays what is sent to it. if the signal arriveing is reversed then you get what you are experiencing.Go to your Home Folder (the one with the house icon) and loctate the Library Folder. In there locate the preferences folder and look for

com.apple.universalaccess.plist

Locate it and put it in the trash.

make sure you have the screen showing the correct way around and then shut the computer down.


Restart and see what happens. If it's still the same, do the routine again but this time leave the screen in negative mode before shutting down.


Post back and let us know what happens.

My Dell E173fp monitor display doesn't work with my macbook


The fine print says it should work. Real life might be different. Do you have a genius bar, found at Apple stores, anywhere close? If so, make an appointment and let them make the connection for you. The genius bar is a free service and I've never found anything that they haven't been able to fix...and fix it quickly...if it's fixable.

Hi i have an apple display connected to my macbook


Unplug the display from your macbook, and restart your macbook, when it's fully restarted and you are logged in, plug the display back in, then check to see if it is detected. Macbooks don't like to be put to sleep (shutting the lid) with a display connected, this causes issues with display detection. So always unplug your display and wait about 5 seconds before closing the lid on your macbook, and when you open the lid, wait another 5 seconds before plugging in your display. The only time it is acceptable to leave the display plugged in when you close the lid is when you plan to use the macbook in clamshell mode, this is done by plugging in and configuring your display, shutting the lid, and then "waking" the macbook from sleep mode with an external mouse (wired or wireless will work). That will start the macbook using the external display as the main display, without even turning on the macbook built-in display. Never connect or disconnect an external display when your macbook is off or in sleep mode. Have a nice day.

Swapping MacBook Screens


As long as the lcd cable connects to the new screen it should work just fine. Just power it on before putting all the screws back to make sure.

In regards to the wireless I don't understand the question completely. The 2006 will probably only have two wires...just make sure they go where the white and black ones did. You'll just lose a lot of the "N" network strength.

Hopefully that answers you questions. If not, let me know.

I have just hooked up an external monitor (LG Flatron) to my macbook--no problem with web pages, but I am unable to see my desktop or any word files. When I boot up, it says analog in the upper right...


  1. When you connect an external monitor to your MacBook (or PowerBook, for that matter), you can combine your MacBook's LCD and your external monitor to create one big monitor. That means when your mouse pointer goes off the edge of one, it will appear on the other. Open the Displays Preference Pane to configure the resolution and orientation of the two monitors. This type of configuration works well when you want to keep your main work on your larger external display, but still keep things like IM, iTunes, and email constantly visible on the smaller laptop LCD.
  2. Some windows act like they don't want to be dragged on to your external monitor. If a windows is being stubborn, try dragging it up to the menu bar, and keep dragging, even if stays stuck below the menu bar. Sometimes once you have dragged it far enough that it has room to render the entire window, it will jump to the other monitor (Terminal used to have this problem, but Apple fixed it some time ago). If that doesn't work, try dragging it from a corner of your monitor. My Adium contact list doesn't seem to want to live on my external monitor, but I can coerce it up there by dragging up from either corner.
  3. When your laptop is open, you can't switch to using the full resolution of an external monitor. I have no idea why, but it's a fact of life for MacBook users. You can use both displays in "extended" mode, or you can mirror your MacBook's display (which most likely doesn't use the full resolution of your external monitor), but you can't switch to using only the external monitor. Very strange.
  4. If you close your laptop, you can actually get the full resolution of your external display. Put your MacBook to sleep, connect your external display and an external monitor, and wake the computer up by pressing any key. You will have full use of your external display while your laptop is closed.
  5. If you really want to have your MacBook open while only using an external display, after following the procedure above, you can open your MacBook, and it's screen will remain off, which means you can still use the MacBook's keyboard and trackpad. Why you can't get into this mode using F7, I have no idea. This is a good technique for allowing some heat to dissipate while still using an external display so the lid of your MacBook doesn't melt or warp.
  6. You can boot your computer using just an external display. Just connect your external display, open the lid, hit the power button, and close the lid again immediately.
  7. In order to output only to an external monitor, you have to have the power cable connected. I tried for several minutes yesterday to get my MacBook to wake up with an external keyboard and monitor before unpacking my AC adapter from my backpack, and it wouldn't work. It took me a while to make the connection (no pun intended), but I eventually discovered that with the power cable attached, everything works as expected.

Macbook recognizes dell projector, but not vice versa


Hello,
Your Macbook should automaticaly find the best resolution, if everything was OK. Is there any HDMI input on the dell projector? What projector is it? Is there is an HDMI input, you can use a HDMI to mini DVI cable: better picture and sound than VGA, and will probably solve your problem
