Laptop Display shows distorted lines when connected to external projector

After updated to 10.6.3 my laptop screen doesn't work in presentation mode with a projector or external monitor connected. The remote image works fine, it is just the laptop screen which distorts. Is anyone else having similar problems? Has anyone worked out how to fix this?

This has been reported by three other keynote users on this forum but Apple has not fixed it yet.

What have you tried so far in terms of troubleshooting this issue? Are you plugging the iPod into a high powered USB 2.0 port on the back of your PC? Have you tried a different USB cable?
What happens if you try to reset the device with it still connected to the PC?

MBP Retina OS X Yosemite has distorted display when connected to Epson projector. How do I fix this?

Hello ATLawson,
Welcome to the Apple Support Communities!
I understand that the display, after connecting to a projector, does not have the image quality you would expect. There may be a few different troubleshooting steps I would recommend in this situation. To begin troubleshooting, I would suggest reading over and working through the information in the attached article.

My 27" iMac displays vertical green lines when turned on and then will not boot up

Can anyone tell me why my 27" iMac displays vertical green lines when it is turned on and then will not boot up?

Welcome to Apple Support Communities
The display or graphic card are damaged. The only thing you can do is to take your computer to an Apple Store or reseller to get your computer repaired.
If you use an external display with your Mac, connect it to your computer and see if these lines appear on the external display. If so, it's a graphic card problem

Cannot change display resolution when connected to external display

On my 2.0GHz 13" MacBook, I have no problem with the display resolution when connecting to external display/projector when I am running in Mac OS, everything work perfectly! But things start to get messy when I am running in Windows VISTA 32 (installed within the Boot Camp 2.1). Whenever I connect to any external display/projector via a MiniDisplay-to-VGA cable, the resolutions on both my MacBook LCD and external display/projector drop to 640x480. And i am not able increase the resolution in the Display Settings. Does this mean that I have not installed the latest version of display drivers? Or is it that Apple did not provide the VISTA 32 drivers (in Boot Camp 2.1) that is compatible with the Mini Display port.

Cool!
I'm glad you have it fixed.

You should also ask this in the MacBook Pro forum. This is the forum for the white and black plastic MacBooks that were discontinued in 2010. You should also post this question there to increase your chances of getting an answer.

Try deleting the photo cache from your computer and then re-try the photo sync and see if they then copy over correctly - the location of the cache, and how to delete it, is on this page http://support.apple.com/kb/TS1314

Ipad 3rd gen shows blank screen when connecting to projector via HDMI AV adapter. I have an ipad 2 that works perfectly. Projector is a Dukane ImagePro 8106HA. Only difference I see is that the ipad 3 owner has not updated to IOS 6. Any thoughts?

Is it possible to open a program when connecting an external hard drive?

Is it possible to open a program when connecting an external hard drive?
I have a external hard drive with an iphoto library. I just want to connect my drive and automatically see iphoto open! Possible?
I know there are some action scripts, am i right?

Ok, here are the steps to take. Doing this involves generating two scripts, the first of which will have the system monitor the attachment of a hard drive, and the second which will conditionally open iPhoto. To make these and set them up, perform the following steps (it is a little involved, but will get you the result you want):
Script 1: A launch agent to monitor attached hard drives
1. Open the Terminal utility in the /Applications/Utilities/ folder. Then copy and paste the following command into it and press Enter, which will open up an editor program in the Terminal:
pico ~/Library/LaunchAgents/iphotodrive.plist
2. Now copy and paste the following text to the Terminal window in its entirety so it is all entered into the Terminal editor:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
          <key>Label</key>
          <string>local.iPhotoDrive</string>
          <key>QueueDirectories</key>
          <array/>
          <key>WatchPaths</key>
          <array>
                    <string>/Volumes</string>
          </array>
          <key>ProgramArguments</key>
          <array>
                    <string>/Users/USERNAME/Library/iphotodrive.sh</string>
          </array>
</dict>
</plist>
3. Use the arrow keys to navigate your cursor down to the place where it says /Users/USERNAME/Library..., and change the text of "USERNAME" to be the same name as your account home folder. For example, my login name in OS X is "tkessler" so my home folder is also "tkessler," so for me this is what should go in place of "USERNAME" in the text above.
4. Now press Control-O to save the file, and then Control-X to exit the editor (use Control, and not the standard Command key here).
Script 2: A shell script to open iPhoto when your drive is attached
1. Type (or copy and paste) the following command in the same Terminal window to make the second script in the same editor:
pico ~/Library/iphotodrive.sh
2. Now copy and paste the following text into the Terminal editor:
#/bin/bash
if [ -d /Volumes/"IPHOTODRIVE" ]; then
        open -a iPhoto;
fi
3. Again use the arrow keys to navigate, and edit the text IPHOTODRIVE to be the exact name of the drive you would like to spur iPhoto to open. The name will be case-sensitive, and spaces are OK within the quotes.
4. Again save this file by pressing Control-O, then press Control-X to quit the editor.
5. Next ensure this new script can be run, so to do this now copy and paste the following command:
chmod +x ~/Library/iphotodrive.sh
Now to activate these scripts you can log out of your account and log back in, and they should work as expeted, and will launch iPhoto only when a drive named "IPHOTODRIVE" (or whatever you edited this entry to be) is attached to the system. This procedure will create two files at the following locations on your computer, so to undo it simply remove these two files followed by logging out and back in, and you should be good to go:
/Users/USERNAME/Library/iphotodrive.sh
/Users/USERNAME/Library/LaunchAgents/iphotodrive.plist
If you run into any problems, then write back here and we can figure out if there are any nuance details to cover for your setup.

I do underwater video and add still photos to the video I create. When playing the video the still shots show distorted lines in any design in the picture and as it transitions to the next photo it clears up for a split second. What is causing this?

The photos are clear for the firt instant the appear during palyback and for the 3 or 4 seconds they are on the screen any pattern or design in the photo, say a patterned tablecloth, the pattern goes wavy, distorted, and then at the last moment before moving on the photo goes clear and smooth. It looks like when the picture goes in the "freeze" mode it distorts and when releasing for the next photo it smooths out again. This is really messing up some very good underwater still shots and land photos. I'm using a transition between photos and not using Ken Burns effect. Could use some help on this. Thanks.

so. to summarize your workflwo in my own words:
you're applying 12Mpix stills to an iMovie project
(btw: what setting has the iM project…?)
iMovie doesn't do interlaced internally…
you then 'share to iDVD'
as far as we know, iM converts to some h.264 file…
iDVD has to convert that again, to finally create a standard DVD:
720x480pix, interlaced = 0.3Mpixel resolution (yes, zero.point.three )
and, you're watching via a projector - most projectors have a non-video-resolution e.g. 800x600, 1200x800:
again, scaling effects.
so, tons of scaling/resizing, tons of comversions …
a) use any graphic tool (your Mac's Preview.app?) to scale the pics BEFORE import to iMovie to your Projects resolution (1920x0180, 1280x720, 720x480); choose tiff or png as doemat, avoid jpg
=> this avoids lossy scaling effect in iM
b) if DVD is your only delivery media, set iMovie's Project preferences to your TV-Standard (PAL/NTSC)
c) from iMovie, use 'Export using Quicktime', and in its options, choose AppleIntermediateCodec as … codec
=> this exports iMovies internal timeline without lossy conversions
d) set iDVD manually to same standard as your iMproject, 25/PAL or 30/NTSC
e) stay under 60min of length to allow max. quality
f) try to find a resolution on that laptop that comes close to DVDs res; synch res of laptop with proejctor
g) consider iDVD solo to create a slideshow; avoids any lossy 'inbetween steps' due to iMovie; very limited in terms of 'creation' … creates a slideshow (with music and transitions)
h) consider to avoid the DVD process at all; export from iMovie a 'file'; use a usb-stick to transfer to playback-computer; allows HighDef! DVD is SDef only ...
to create a file whic is compatible with any computer, follow my advice here:
How to create a video for playback with Windows/XBox/PS3/… etc?
For maximum quality of stills, I would use iDVD only (disk, but SDef only);
or avoid disks at all, create a charming HDef iMovie project and transfer via stick

Bad Screen Laptop Screen - showing blue lines instead of black

I have an old laptop HP Pavilion DV7-1448dx, the screen shows blue lines instead of black. I tried using TV as a monitor and it doesnt have any problem, it only shows on the laptop. I replaced the LCD screen with a brand new screen but it still shows the same problem. I attached the pictures of what my screen looks like. It only shows this on the black color and the others are ok. Pls help!

@luv2travl ,
Hello and welcome to the HP support forum. Thank you for posting about your display issue.
It sounds as if the RGB output of the graphics card has become a bit off in your case. You have replaced the screen so the output that supplies the LCD from the graphics card is the issue.
As you stated on a VGA output to a TV it looks normal. Therefor it isnt the card totally having the problem.
Here is a link you can check out on display issues.
Display Quality Issues
Here is a link to your systems Maintenance and Service guide as well. One thing you may want to check is the actual cable that connects the screen to the motherboard. This is the easiest and cheapest part to work with.
If you replace the connection cable from the motherboard to the monitor this may fix the issue.
