Dual displays ("extended desktop") on the iBook

This is in response to a previous query that was strangely archived despite the original poster receiving no definitive answer.
The iBook G4 (and various other iBooks) does not support "spanning" dual displays (I believe Apple calls this feature "extended desktop") with Leopard. Evidence of this is the missing "Arrangement" tab in the Display system preference pane.
The Tiger version of Spanning Screen Doctor (http://www.rutemoeller.com/mp/ibook/ibook_e.html) does, indeed, work correctly on an iBook G4 running 10.5.4. After rebooting, the "Arrangement" tab will now appear in the Display pane.
Hopefully this saves some iBook users some time and effort in resolving this issue.

Thank you for yor help.
I have one more question to ask? If I use the LCD TV like Sony or Samsung with the New i-Mac will I loose deskspace on the LCD TV due to the low resolution on the LCD TV? I thought the LCD TV was a good idea since it has all the input for all my DVD player, TV box?, Nintendo, and the VHS?, but I was told that LCD TV might not be too compatible for use with a computer.
How do I put all my stuff on a Apple 23" LCD display I only can find adapters that can only take one peripheral at a time, and I don't want to re plug a TV box each time I want to watch TV. It looks like I need a box for use with Apple display with 3~4 input and S video, and HDMI input for the HD stuff?
Again thank you for all your help.

Princeton dual display extended desktop

This is my first apple...I have the G5 quad and I hooked up my two Princeton LCD17 monitors, with the adapters. They both have the apple background screen, but only the right monitor has cursor function, the left is just the blue background w/the info screen on the resolution. I've played around with the resolutions...but to no avail. Are the princeton's compatible for extended desktop? Thanks.

Good evening!
Maybe I can help. Maybe I can't. But I'll try.
I have a Princeton 19" VL193 lcd here, and a 15" LG 566LM lcd.
When I turn my system on, it automatically goes into extended mode, giving me my normal 19" view with background and menu's and dock.
The 15" shows a blank screen. So I went into the SYSTEM PREFERENCES under the APPLE menu. In there, go into DISPLAY. Each screen should show it's own resolution settings. I can set each screen's resolution and refresh rate, as well as colors, independently of each other.
On the MAIN screen, there is the option to "mirror" the screens, and then they will show identical images etc.
That's what you SHOULD see.
If now, there is the option to "DETECT DISPLAYS" on the DISPLAY screen.
So they can run seperate backgrounds / wallpapers, or identical.
Let me know if this helps at all.

Can my computer display 'extended desktop' with a second monitor?

I believe I have a G4 Quicksilver 867 (2001) (bought it used and figuring out which model G4 is not that easy). I recently got a second monitor, but I only seem to have the option to have a mirrored setup (which works well). Is there anything I can do or rather what are my options to get it to show extended desktop. My video card is
Chipset Model: GeForce2 MX
Type: Display
Bus: AGP
Slot: SLOT-1
VRAM (Total): 32 MB
Vendor: nVIDIA (0x10de)
Device ID: 0x0110
Revision ID: 0x00a1
ROM Revision: 1049
Will I have to get a new graphics card or is there a workaround of some sort?

Thanks, not what I wanted to hear, but helpful. hope you'll answer a couple of questions. I bought this computer as a second (do taxes, surf the internet, connected to my wireless router, escape my three kids wanting to use the primary). I've been very happy with it for its limited use (my primary is one of the first Imac G5's).
1st: Do you think it's worth putting a faster processor in it? My G5 has the latest OS, but I'm hesitant to go past 10.411 with the G4 867
2nd: Would you recommend a video card update to run extended desktop?
3rd: Can you run extended desktop on the original IMAC G5's (1.8 ghz, GeForce FX 5200, 64 mb ram)?

Dual DVI Displays (extended desktop) via 1 HDMI Port ?

Hi, I have a late 2013 MacBook Pro w/Retina Display 15” Quad Core 2.6Ghz i7 with 16Gb ram.
Running the latest OS (10.10.3) and all latest updates, etc..
I have 2 23” Apple Cinema Displays which are DVI. I would like them to be used as “Extended Desktop” style on this computer.
I understand this is possible via the Thunderbolt ports (correct?), but would ideally like them to come out the HDMI port (and work like “Extended Desktop”).
This is because I will have the bandwidth of my Thunderbolt bus maxed out. And would hate for the video to slow anything down as I will have many drives and interfaces on the TB ports that need the data.
I am not looking to mirror the displays, but want “Extended Desktop”. I am hoping the 1 HDMI port can support that somehow, maybe with adapters ?
Any input would be greatly appreciated as far as my options.
Thanks !

This thread can be deleted, as I am not getting enough response here, so I posted in another forum.

Extended Desktop Mode on iBook G4

I am trying to configure my iBook G4 to use extended desktop mode with a Dell M780 monitor. I currently have the Dell monitor mirroring the iBook display, but would like to have it in extended desktop mode.
OS X Help Viewer tells me to go to System Prefs > Displays > Arrangement, but when I go to the Displays section there are only two tabs: "Display" and "Color", and there are no other buttons, menus or anything related to arrangement.
My graphics card, which perhaps has something to do with this, is an ATI Mobility Radeon 9200. There are 32 MB total of VRAM. Core Image is not supported on either the iBook display or the Dell display.

Hi Mathew,
Welcome to the forum.
The iBooks do not support extended desktop. Should you wish to have this feature, you can with a third party solution. More details here:
http://www.rutemoeller.com/mp/ibook/ibook_e.html
Be aware, if your iBook is under warranty or you have AppleCare, this could be void if there is any damage caused as a direct result of applying the above. That said, a lot of people have done this without any issues. Infact I have yet to come across anyone who has had issues.

Dual Monitor (Extended Desktop) Information Requested

Hello,
I am gathering information regarding the addition of an additional monitor to serve as an extended desktop for my iMac 2GHz Intel Core Duo (purchased in early 2006).
Questions:
1) Is it possible for this 2 1/2 year iMac to have an additional monitor?
2) My iMac has a Mini-DVI port on the back. While looking at other monitors, I have been seeing 15 pin High-Density D-shell (VGA), Video - 24 pin DVI-D, and Video - HDMI interface inputs
3) Which one of those interface types is recommended?
4) Does Apple require a proprietary cable to connect with the above mentioned monitor?
Thank you for any information!
Tony
3)

Yes it is possible to have an additional monitor. I would compare the 20" iMac display to DVI quality although I believe HDMI is the highest quality (probably comparable to the 24" iMac displays). You will need a mini-DVI adapter to connect any display (see link below). I would recommend a DVI connection using a monitor the same size as your iMac that can handle the same resolution as your iMac display. If unsure what this resolution is go to system preferences>displays.

You can also read some of the reviews from this mini-DVI adapter as most of them are trying to do what you are doing. You will also need a standard DVI cable (sometimes included with monitor) to connect to the new monitor to this adapter. There is also a mini-DVI to VGA adapter - although I wouldn't recommend this connection because it will be lower quality than your regular display. And a cable that connects DVI to HDMI if you decide to go that route.

24" iMac and 20" Cinema display extended desktop mode ?

I got a 24" iMac and a 20" Cinema display. I wanted to know if they will work on extended desktop mode? I didnt try to hook it up yet as I am waiting for mini dvi to dvi adapter to come.
Thanks

Hi,
according to this http://developer.apple.com/documentation/Hardware/Conceptual/HWTechVideo/index.html#//appleref/doc/uid/TP40003504
you should have no problems (you must scroll a bit down the iMac 24" section)
Have Fun

Second display extended desktop?

I just hooked up my second monitor.
When I bring up displays it gives me the mirroring option.
When I click it I get the same as the first monitor.
How do they set these for FCP X editing.
Extended desktop I thought it was?

You want extended. See the following it should work for Yosemite

About the extended desktop on the Intel iMac?

Hi I was looking into getting the 17" Intel iMac, but after looking at the 20" G5 iMac, I think I want the 20" Intel iMac. I wanted to know what size external display can you use with the 17" & 20" Intel iMac as a extended desktop? I was told the reason that I only can use up to 20" external display with my 12" PowerBook was the graphics card in it. I think you can get 128 MB and 256 MB with a Intel iMac? what size display can I use with this type of card?
I want to put a 23" or a 26" LCD TV on the 20" Intel iMac if you can? Hoping to use a 26", but 23" is OK too.
Thank you for all your help!

Dual display, multiple desktops

Hello everyone.
I've recently purchased a 2nd monitor for my pro, and came across the issue of having the 2nd montior change each time I change the desktop I'm currently using. After some searching online, I've found out that there is no workaround for this issue.
My plan was to have 1 program on the 2nd monitor (watch movies, farm on WOW etc), while I do 'real' work on the laptop. Not being able to use the multiple desktop feature ***** since I've gotten used to it and use it quite often.
Now, I'm running OSX 10.7.5, so I was wondering if the solution to my issue was fixed in the latest OSX. I never really had a reason to upgrade, but if I can have the 2 monitors set up the way I had planned, I would definitely upgrade.
Cheers

You've done all the relevent troubleshooting (reinstalling the OS probably was over the top though). I suspect the cable. Do you have a friend who was a computer with the MiniDisplay Port or are you close to an Apple store? If you can check the cable before going to the expense of getting a new one that would be good.

Screen Sharing: Viewing extended desktop on extended desktop

My buddy and I both have the same current versions of iChat and Leopard and both have dual displays (extended desktops). When we do ScreenSharing, his dual screens (the entire extended desktop) come through into just one screen of mine (into the larger primary screen but I don't know how iChat determines it) and vice versa when I share my screen with him. We can still see everything, but everything is just smaller to fit two widths into one. The second screen remains dark and blank.
Is there a way to enlarge the shared screen?
Or is this a limitation at the current version?

But of course I want more, not less. The second screen contains all the important tool palettes, which is half the experience! I will nonetheless try (looking for) your suggestion next time, if just to know it. Thanks.

Extended desktop issue under XP SP3

I'm running Windows XP SP3 on my MacBook. The Intel GMA 965 driver will allow me to do the following combinations:
Just the laptop display
Just the external display
Mirrored displays
Extended desktop with the notebook as the primary display
Surely there must be some way to do an extended display with the external as the primary display?

Same problem here... We have about 6 new Macbooks that absolutely need this functionality or they're going back.

G4 Extended Desktop via 'dual display'

My G4 has two outputs from the Nvidia Card, a standard vga and the
'rounded edge' style AppleDisplay output. Two part question here:
1) may I simply use an appledisplay connector-to-vga converter dongle,
in order to send through that second output to a standard vga (non apple)
monitor?
2) Would using these outputs simultaniously render the 'extended desktop',
or are they just a duplicate of the same output?
Thank you kindly for any info on this.

It depends on which NVIDIA card you have. Anything older then the GeForce4 MX won't run two VGA displays. The GeForce2 MX TwinView can run two displays, but the ADC to VGA adapter won't work with this card, so only one can be VGA.
If your card does support dual displays, you can choose mirrored or extended desktop in the "Arrangement" tab of "Displays" system preference.

G4 iBook and extended desktop

I am using my G4 iBook to connect to a projector for presentations and have noticed that MS PowerPoint 2004 allows projecting of the current slide whilst I can see next and previous slides on my iBook screen. However in order to do this I have to switch off monitor mirroring. However in order to do this I need extended desktop, which it would appear that my G4 iBook does not have!!! Is there any way of getting an extended desktop on my iBook in order to use this functionality?

On an iBook, you can't.
One of the things Apple does to distinguish the 'consumer' line (iBooks and iMacs) from the 'professional' line (PowerBooks and PowerMacs) is that it prevents dual displays on the consumer line. We know from the video chips that Apple uses, that they are capable of dual display.
There does exist a hack that undoes the lockout that Apple wrote into the consumer line, but Apple is very clear that installing that hack will void your warranty and possibly damage the computer. This damage is (from what I have been able to glean) from overheating, especially from users that close their laptops while using an external monitor, as venting heat through the topcase is part of the design.

Mac extended desktop mirroring needing to 'split' the sound

The setup is that I am using my iMac in one room (the study), and I am using airplay to extend the desktop so that my apple TV in the living room is used to play a movie for my parents to watch.
The sound and video transfers just fine to the apple TV on 'desktop 2', but I was wanting to be able to play a seperate video on my imac, in the study. I can't seperate the sound. Even though the video is on 'desktop 1' on my iMac any video's sound on either screen will be played through the TV speakers as my System preferences only allow me to select 'iMac' or 'apple TV'
Is there any way to 'split' the sound?

""Extended Desktop" and "Dual Display" mean the
same thing..."
Actually, they don't. "Dual Display" simply means
that the computer can support two displays. "Extended
Desktop" and "Desktop Mirroring" refer to the
different modes in which the two displays can be
used. "Extended Desktop" uses both screens as one
large continuous desktop while "Mirroring" displays
the same desktop image on both screens.
O.K. I'm confused.
Can the Macbook display extended desktop (one giant desktop with half on the laptop and half on an external monitor) or is it limited to just mirroring the same desktop on both displays?
Thanks,
Mac OS X (10.4.5)
