External LCD will not display red

I have an external LCD monitor that has worked fine in the past, but today will not display the color red. Red is displayed as a grey. The monitor is functioning properly, as proved by connecting to another computer using the same SVGA cord. The mini-VGA to VGA adapter was not used when the second computer was used to test the display. Adjusting the calibration seetings on my iBook do not help. There do not appear to be any missing or bent or dirty pins.
Could this be a problem with the mini-VGA to VGA adapter supplied with the ibook or the mini-VGA jack itself?
If so is there a not so expensive solution?
Thanks

The adapter is only $19US.

External Monitor will not display full view MS apps.

I have a HDMI monitor that was previously working fine. The other day I went to use Word and Excel and the applications would only appear in the lower toolbar. When I would select them they would not enlarge. They remained in a thumbnail view. My email and Internet work as expected. Any ideas what's causing this?

MacBoook lcd screen black/gray will not display

My MacBook LCD screen will not display. It powers on but I cannot see anything on the screen. What is happening?

You could try a pram reset, although I'm not sure it will do anything.
To reset your computer’s PRAM:
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Immediately press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.Continue holding the keys down until the computer restarts, and you hear the startup sound for the second time.
Release the keys.

was recently sent a very large emoji message amd now when i try to acces messages it will not display mesagges and then will bring me back to the home page

Quit the messages app and reset your phone.
Go to the Home screen and double click the Home button. That will reveal the row of recently used apps at the bottom of the screen. Tap and hold on the app in question until it jiggles and displays a minus sign. Tap the minus sign to actually quit the app. Then tap anywhere on the screen above that bottom row to return the screen to normal. Then restart the app and see if it works normally. Then reset your device. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider should one appear until the Apple logo appears. Let go of the buttons and let the device restart.
After the phone restarts go into Messages and delete the thread containing the problem message.

My iMac will not display anything on the built in monitor. I have hooked up an external display to the thunderbolt port and it works fine on the external. I have tried to detect displays and it still cannot find it. I have tried a SMC Reset and PRAM Reset and also reseated the ram.

Ipad will not display email content

ipad will not display email content just 2 lines

Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
Or ... Quit the mail app completely and relaunch mai. Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar. Launch the mail app.

Mail will not display, screen returns to home screen when I try.

MMail will not display or load up. When I enter the mail icon it instantly returns to the home screen. Therefor mail will not display or show.

The Mail App is crashing on you. You might have a corrupt email, a spam email or an email with a very large attachment that is causing the crash. It could also be a corrupt setting. It's difficult to know that it could be. If you have a computer, log into your email account in a web browser and look for any problematic emails and try deleting them there.
Try closing the mail app completely on the iPad, reset the device and then try mail again.
In order to close apps, you have to drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
Next, reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

HT1430 My inbox will not display all messages

My inbox will not display all messages

Close the mail app and reboot the iPad.
Tap the home button once. Then tap the home button twice and the recents tray will appear at the bottom of the screen. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the mail icon. Tap the home button twice.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Flash appears to install on Win 7, IE 8but will not display

32 bit Windows 7
IE 8, 32 bit
FP 10.2.152.32
FP S/W installation windows indicate that FP installed (Download Manager also says so)
FP & Download Manager are both shown in Programs.
History: Few weeks ago system was severely corrupted even though had McAfee Viruscan and Webroot Spysweeper. It was indicated every time an attempt to look at a video was made wherepon the computer would shutdown a few seconds afterwards. Working w/ Dell Support they determined the system was too far corrupted to save (7000+ files corrupted!!). They suggested that it would be preferable to install W 7 to replace then current XP operating system. Had disk formatted and XP operating system re-installed but only sufficient to allow operation of email. When Windows 7 arrived fully installed along w/ new Word/Excel 2010 S/W. Retrieved backuped files successfully. Everything is operating OK except for FP. Every attempt to load (after repeated uninstalls) shows it to be "successful" but still won't allow videos to play.
Based on perusal of thread, opened register to check on "kill-bit", found no indication it was set.
What should I do next?

Hi, what a terrible experience to have to go thru! I hope you don't still have either one of those "Anti-Virus" programs on your system. If not, what Anti-Virus/Spyware program(s) do you have?
Yes it was terrible, but Dell (Solution Station, paid support) made this sickening experience bearable. Right now I have McAfee Total Protection 2011 for what it's worth (ya gotta have something) and I use Malwarebytes Anti-Malware (free version) twice a day to scan. The only thing it finds repeatedly is something in the registry defined as : HKEY_CLASSES_ROOT\regfile\shell\open\command\...
So I can understand this, you now have Win7 on the computer? The backup files are from the XP that had the 7000 corrupted files?? When you reformatted XP, weren't those files lost? I guess what I need to know is how did those files get Installed onto the Win7 OS?
Here's the sequence of events: I back up periodically with a WD My Book Essentials external drive, assuring that the system is as clean as I can get it and otherwise operating normally. I don't do it continuously for fear that I could be backing up corrupted files right up to the point the disk crashes The back up that was used was about six weeks old. The 7000+ corrupted files were cleaned before reformatting but would have been lost regardless when the disk was reformatted. After it was reformatted and before installation of W7, the Dell reinstallation disk for XP was used. No backup files were loaded on this temporary XP system. When the W7 system was installed these backup files from the external drive were cleaned with Malwarebyes which found about 20 corrupted files. Since then only two have regularly appeared , they are in the registry defined as: HKEY_CLASSES_ROOT\regfile\shell\open\command\def...
Also why wasn't the malware cleaned before reformatting?
As indicated above, it was cleaned but never used again since it was all lost with the reformatting. The reinstalled software came from a six week old backup which has worked well and shows none of the malware, except for the few Malwarebytes intially found.
One other thing, I revisited the "kill-bit" procedure. While I didn't find what you indicated, I did find these two entries with HKEY_LOCAL_MACHINE\SOFTWARE\ :
      Name                        Type                    Data
"icon w/ab in it"             REG SZ            (value not set)
"icon w/ab in it"             REG SZ            application/x-shockwave-flash
Also, I was looking at your procedure in post #26, in response to jfirko where a vs 9 of FP is installed/uninstalled followed by the current version of FP. For my situation is this a worthwile approach?
By the way, thanks for your interest in solving these problems. So many programs now use the flash player but there are so few sources to turn to when problems occur.

Uspto.gov TIFFs will not display

I just "upgraded" to 10.6. ( This is an old issue on this chatboard.)
How can I make 10.6 display TIFFs on uspto.gov like 10.4 did?

Best solution I have found is to use alternate patent sites such as www.google.com/patents.
Having said that, below is a partial solution that usually works on newer patent pages (red buttons at top).
Safari 5.0.5 -- On USPTO blank image page, click Front Page, Drawings, etc, and click/drag from the left part of the blank page (where the image should be) and drop on the desktop. Unfortunately, only the first drawing of a series shows up. Changing User Agent from the Develop menu doesn't help.
Firefox 7.0.1 -- Will not display or download TIFFs on USPTO site.
However, Library of Congress TIFFs can be automatically downloaded by changing FF Preferences / Applications / Search / tiff / Action to Save File.

Satellite A300 PSAG0A - Games Will Not Display in Full Screen Size

I have a large number of games installed on my computer. At least 90% of them will not display in full screen size but display in a small window with a large amount of black screen surrounding the window. I am running Windows Vista Home Premium 32 bit. However, I do not think it has anything to do with Windows as my husband runs the same games on his Toshiba Satellite L300, running exactly the same version of windows, and they all display in full screen size.
Altering the screen resolution makes no difference. And, of course, I do select the full screen option in the games.
Also, sometimes when I have been playing a game and then closed it I find that my desktop picture has shrunk to the smaller size - the same size as the window in which the game was displayed when I was playing it.
The games work fine in every other way, it is only this small screen size which is driving me nuts.
I hope that someone can help me with this!!

Yes, as far as I can tell I have the latest driver. But, even this is confusing to me because....
My graphics media accelerator is Mobile Intel(R) 965 Express Chipset Family. The installed driver version is 7.14.10.1329. The release date for this is 2007-09-13, as far as I can tell from web searches.
However, on the Toshiba website for driver downloads, the available driver version is 8.2.0.1012 PV. The date is 2006-12-28. I have downloaded this driver and attempted to install it. I get the message that it has been installed but, after rebooting and checking the installed driver version is still 7.14.10.1329.
Perhaps, the 8.2.0.1012 PV version does not actually install because it is older than the currently installed version. I would have thought that the driver version with the higher number would be the newer one, but perhaps this is not the case as the dates do not seem to support this theory.
So now I ask myself, firstly, if the driver available for download on the Toshiba website is not the newest one, then why is it there?
Secondly, if it is the newest one then why will it not install on my computer?

The menubar will not display in full screen

Hi.
I have a strange problem in fullscreen mode, on my Macbook pro 15"
I LOVE fullscreen, and infact the next macbook I will get is the 11" air because of its size and because full screen is so nice to work with.
But I have a strange problem which I can't find a solution for.
Suddenly the menubar will not display it self when I move the mouse to the top of the screen. The only way I can access the menu bar is by exiting full screen (ctrl + Cmd + F) and the toggel it back on after I have used the menubar
This actually makes fullscreen mode useless and its driving me nuts, because this should not happen on Apple software. I would expect these sorts of behaviour on windows but not in osx.
Anybody have a hint about what to do?

Try this: make a temporary, backup copy (if you don't already have a backup copy) of the library and try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
     User/Home()/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
     User/Home()/Library/Caches/com.apple.iPhoto folder.
Click to view full size
3 - launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto. You'll also have to reset the iPhoto's various preferences.
