Video Mirroring / Extending the desktop

I have a 12" iBook G3 800mhz dual usb and have just bought a Samsung TFT 17" which works fine and plugged straight in using the apple adapter. I wanted to extend the desktop to have palettes etc. on the laptop screen, then use the 17" for the file window. Is this possible at all on an ibook, or do I need a new graphics card or something? any help appreciated

You really need a PowerBook to do screen spanning. There is a software hack that will enable you to do it, but it is not recommended by Apple, and can endanger your iBook (i.e., kill it dead). I RECOMMEND THAT YOU NOT DO THIS. I don't usually even post the link.

I have a MB Pro that is running Lion; I also have two external DVI monitors and a DVI splitter in hopes that I could run the two monitors with my MB Pro. This actually works fine, but I am unable to "extend" the desktop. Any insights?

You cannot have a extended desktop using a splitter. All that does is mirror the pair attached to the splitter.
You can do this however using a Matrox DualHead2Go.
Other solution would be to attach one monitor to your video out as you do the splitter and attach the other via USB (assuming the adapter supports the monitor's resolution).

Am I able to extend the desktop when a 27" display is attached to my IMAC 27"

Am I able to extend the desktop when I use a 27" IMAC and a 27" extra display?

Hi Donald,
Go to System Preferences > Displays > and you should see two different windows, one for your iMac's display and one for the extra display. Click on the one for the extra display. Click on the Arrangement tab at the top. In the lower left corner, uncheck the box for "Mirror Displays" and it should go to extended desktop. You may also wish to check the box for Show displays in menu bar if you need to access the Displays pref frequently.

Ok....I have a 2012 MBP that has Yosemiti installed. The airplay works from iTunes, but when I try to mirror from the desktop I get the "no device detected" message. Airplay on all of my other devices work fine. Has anyone else had this issue?

Possible to add a monitor to extend the desktop (not mirror)?

Do this on all my desktop Macs for reducing clutter (holding palettes).
iMac G5 20". Added a 17" VGA monitor via adapter, but only get them to mirror with same display settings for each. Want a continuation of the desktop.
Is it possible to have another monitor with the iMac for this purpose?

I am lost and need some assistance. I tried to install an anime program on our iMac and found we did not have enough available disc space. I then moved a bunch of software off the hard drive and onto the Applications and personal folders. However, I think I may have moved critical start up and operational files out of touch with the machine. I froze on the desktop with a spinning pin wheel. I unplugged the computer. When I plugged back in and tried starting it up I got to a black screen with grey and white alarms and alerts with code. I could not move from this spot. Then it sounded like an internal drive was starting to spin into orbit. I shut the computer off and I'm afraid I have ruined my best teaching aid. H-E-L-P!!!!!!

How can i extend the desktop of my retina Macbook using an ATV?

Hey,
i know i had this working before, but i was using the developer preview of mavericks in that time. So is it possible?( or is it even a feature that comes with mavericks?) and if so: how would i do it?
i'm only offered the option to mirror the screen currently.
Any help would be great.
15" rMBP
ATV3

It's an announced feature that will come with OS X Mavericks > http://www.apple.com/osx/preview
Until then, a third-party app can extend your desktop to your Apple TV, like AirParrot > http://www.airsquirrels.com/airparrot/

Extending the desktop

Hello-
This is my first visit/post here, and I am hoping that someone can help me!
I am running Windows XP, with the G4MX440-T card.
I do a LOT of work in photoshop, and in the intrest of streamlining my work area, I have attempted to extend my desktop with a used (but working!)$1.99 color monitor, and a ($9.00)VGA splitter. So far, my investment in $ is reasonable ) , however my frustration level is not ;( .
I was told by several folks theoretically in the know, that this should work, but no luck!!
Any ideas?
Thanks--Frank

Hi Frank,
A VGA splitter will only split a single input into two or more identical outputs - so you'll get the same picture on both monitors.
What you need is two separate VGA outputs - either a "dual-head" video card, or if the motherboard has onboard video, you can use that (you may need to enable it in BIOS). It's probably best to use the graphics card output for your main photoshop display, and the on-board output for the old monitor (although it may be useful if that is designated as the "primary" output, and you open photoshop on the "secondary" monitor).
Hope this helps,
Mike

Can't Export Video Files to the Desktop

Since upgrading to Leopard, I am not able to open .mov and .mp4 files exported out of iMovie 06 and MPEG StreamClip to the desktop. The error message complains about a lack of disk space or improper permissions.
An export to an external drive worked, and files will burn to a DVD.
Any ideas?

HI jboppre,
Welcome to the Sony Community!
The lock symbol on the videos could mean that the videos themselves are protected or the memory card you're using is on locked position, thus preventing you to export/transfer your files to a computer,
To unprotect the files, please click on this link. And to unlock the Memory card, slide the lock lever up or unlock position.

Extending the Desktop to External Display

When I connect my MacBook (2GHz Core Duo, 512 MB) to an external display (projector, HDTV) I get the "default" desktop background on that display, not the image I currently have set as the desktop on the MacBook's display. How do I make the desktop image track to be the same as the MacBook's? Is there a way to "stretch" those desktop images to cover both displays? By the way, I'm using the built-in Apple desktop images.

Hey,
I believe what your experiencing is the Dual Display Option. The MacBook will automatically start up in dual display mode. This means you can use both your MacBook Monitor and your external for screens. To have a mirror image press F7 to toggle between mirroring and dual.
Give that a try.

I can not find the display preferences tab to turn on video mirroring. Any suggestions?

I'm trying to get my Macbook Pro to stream to a Samsung Smart TV. I just came from the Apple Store and they told me I need to turn on Video Mirroring. I went to System Preferences/ Display but can't find Display Preferences or the box to check for Video Mirroring. The only tabs are for Gather Windows and Detect Displays. It does detect the Samsung TV but how do I turn on the Video Mirroring? Any suggestions would be greatly appreciated. I am using Lion (if that means anything.)

Does the problem happen only with specific sites? If so, what sites? Also, have you tried testing the iPad on a different network to see if the problem goes away? It is possible that you may have some kind of ad blocker or anti-virus software that is doing something to prevent the ads from appearing on the laptop, which would explain why you're seeing what is probably a network-related problem only on iOS.
Unless you have jailbroken your iPad, or have otherwise accepted the installation of an app from a website rather than the App Store, there's no known adware or malware capable of infecting it. If you have done one of those things, you should restore your iPad to factory defaults, and should not restore anything from a backup.

Pixelated video mirroring from Macbook Air (X10.8.5), but not from my iPod i0S7

I don't understand it. when I mirror anything from the macbook, the output on the Apple TV is pixelated, as if very low resolution. E.g., streaming Amazon. I streamed the same content from my iPod and the output on the Apple TV was perfect.
This is a new problem--just in the last couple of weeks I think. I don't often mirror from either to Apple TV, but I know I had excellent resolution from both in the past. Gone through all settings and am mystified. Any ideas?

Optimizing image quality
Resolution matching modes
You can choose between two desktop resolution matching modes that let you select which display will have the best image. When AirPlay Mirroring is turned on, select an option under "Match Desktop Size To:" in the AirPlay Mirroring menu extra.
Match Desktop Size To: Apple TV
AirPlay Mirroring changes the desktop resolution to best match your Apple TV, resulting in a 16:9 image that fills the HDTV screen. This setting often produces the sharpest image on the HDTV. The aspect ratio and/or resolution of the built-in Mac display may change to accommodate the Apple TV.
Match Desktop Size To: This Mac
AirPlay Mirroring scales the contents of the desktop to fit on the Apple TV, leaving the resolution of your Mac's display unchanged. Use this setting for the sharpest image on your Mac's display. Depending on your Mac model, the resulting image may not fill the HDTV screen.
Have a nice day,
Mario

IPad2 and VGA/Video Mirroring...

I'm a teacher with a VGA projector in my classroom. I really want to get an iPad2, but I've been holding out until I could justify the purchase by using it in class (Maps, Safari, Keynote, Pages, using the cameras to record video of the kid's projects, etc).
I've been reading a lot of vague information about video mirroring, I realize that the HDMI adaptor will mirror my brand spanking new iPad to an HDTV, but that's worthless to me in the classroom. I've read a lot of people who think that video mirroring will work with the VGA adaptor and an iPad2. Can anyone definitively tell me that iPad2 and iOS4.3 will support video mirroring with the VGA adaptor so that I can use it with my classroom's projector?
Please let the answer be yes, that would be awesome. If not... Can anyone think of a workable solution? HDMI adaptor --> HDMI Cable --> HDMI to VGA adaptor --> VGA cable?
Thanks.

Scroll down the page to Apple VGA Adapter. http://www.apple.com/ipad/accessories/
It says, "Share what’s on your iPad screen with an even larger audience by connecting your iPad to a TV, monitor, projector, or LCD display that uses a VGA connector." That's full mirroring.
This is a new description for the VGA Adapter, the old description is available if you click through to "buy now". The adapter appears to be the same, I think the difference will be iOS4 software that allows full mirroring.

StageVideo on the desktop

I'm in shock.
Why is it that Adobe Air does not support StageVideo on Desktop profiles, but it does in TV?
http://help.adobe.com/en_US/air/build/WS144092a96ffef7cc16ddeea2126bb46b82f-8000.html
Will it be supported some day?

I'm trying to play a 720p video with adobe air and this is simply unacceptable. The performance is bad.
A flash projector with StageVideo works better, even with a 1080p video.
Adobe air is simply unusable for HD video playback on the desktop.
