Extended desktop GeForce2 MX

Hello All-
I just remembered my login and password so thought Id ask for help with my most current plan issue.
I have been searching for a way to 'extend' my desktop to my Flat Panel iMac. After researching on here and elsewhere, in addition to purchasing a mini-VGA to VGA adapter, I realized I did not read some fine print.
Am I correct in seeing now that because I have the 15" iMac G4, 800MHz with the GeForce2 MX, that an extended display is not possible even with the help of Screen Spanning Doctor?
I have this lovely Dell flat panel monitor hooked up to another machine here and I'd much rather put it to use with my iMac.
Is it a Hardware issue that is easily resolved by purchasing a new graphics card or something similar (sorry I am bad with hardware).
Any ideas?
At this point I'm thinking if nothing else maybe I can boot up to my MacMini in Target Disk Mode and the extend 'her' desktop.
Thanks in advance for any help or advice!

Hello,
If you hook the Dell monitor to the Mini and then use ScreenRecycler (thanks Niel!) with the iMac G4 then I believe the Mini could use the 15" iMac display and the Dell display. Bear in mind this will be resource intensive.
Let us know how you get on.

15" G4 Extended Desktop

I've been looking around at that Firmware hack that allows for extended desktop on iMac's, but the 15" 700MHz is excluded from the list. Of course, that's the version I bought to use specifically for Keynote presentations. I assumed since it had VGA out it supported extended desktop just like the rest of them. It's got a GeForce2 MX in it, which Nvidia's site says supports dual monitoring.
The warranty on this thing is gone anyway, so I really don't have a problem with messing with the Firmware, I just need any kind of down and dirty trick to allow extended desktop on this iMac.
Thanks in advance!

AFAIK this can't be done. Sure Nvida's PCI version can dual display but it hasn't had the firmware crippled by Apple.
Screen Spanning Doctor (firmware hack) will allow most iMac G4's to dual-screen but not the 15" 700MHz or 800MHz models.
I present every morning at work (Admittedly it's Office 98 on a WinNT PC so can never be too complex) and never use a dual-screen set-up. You'll have to live with the single-screen setup or get saving for an Intel iMac.

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.

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)?

Tablet PC calibration error in Adobe Photoshop and Illustrator CS3 whilst in Extended Desktop Mode

Hey everyone!
I've run into a snag which hasn't bugged me before because I never used a second monitor, but now that I do, Photoshop and Illustrator don't function properly.
I am running my Adobe products on my Lenovo X61 Thinkpad Tablet, which is Wacom PenEnabled. It's got the basic digitizer pen and pen pressure features, no stylus tilt or anything.
Whenever I run Photoshop or Illustrator in Extended Desktop Mode so I can have a different window open on my external monitor and the Adobe app on my tablet screen, my stylus goes strange. It seems to think that the extended desktop is part of the Adobe window, so when I move my stylus to draw, the cursor will appear on the external monitor, usually proportionate to the size of the screen...ie. It interprets the external and tablet screens as one desktop and the top left corner of my tablet screen is the top left of my external, whilst the bottom right on tablet IS the bottom right on tablet, if that makes any sense...sorry.
So I can't draw anything in photosho unless I set it back to standard desktop mode, or mirrored desktop. I've searched over the net and these forums and I can't find a fix for this. I was walking in harvey norman the other day and the Wacom Cintiq 12" was there on display, and it had the same issue with extended desktop and photoshop.
Has anyone had this issue before and/or does anyone know of a fix for it? I'll keep searching around and playing with the computer until I fix it and I'll post any solutions I find here if noone else has one.
My system details are:
Abobe Photoshop CS3 10.0.0
Adobe Illustrator CS3 13.0.0
OS: Windows Vista Build 6001, Service Pack 1, 32bit
RAM: 2GB
HD: 18.2GB free Disk Space (out of 66.3GB on the Active Partition)
Video: Intel GMA: Mobile Intel(R) 965 Express Chipset Family

I'm using an HP tx2011au tablet pc, using adobe flash cs3 and have the exact same problem. it becomes decalibrated only while the flash window is open, and only while flash has a file open, and only when using an extended desktop. even if flash is open and it has no files open it works fine.

I cannot get my iMac to connect to my macbook via Thunderbolt to use my laptop as an extended desktop

I am trying to connect my iMac 21.5" desktop to my macbook pro via Thunderbolt cable so that I can use my laptop as an extended desktop. I have tried using detect displays to get it to show up and nothing happens. I've tried doing command + F2 to make it a targeted display, but the only thing I can get to happen is my iMac will mirror my Macbook and that's not what I want. No matter what I have tried it hasn't worked. I have tried turning both computers off and I have a brand new thunderbolt cable. I've updated all the software. Is there anything else I'm missing??
I'm running OSX Yosemite 10.10.1
Thank you !

We've already done all of that. And we used the same thunderbolt cable to connect two iMac's and that worked totally fine doing the Command+ F2. I don't understand why we can't get the macbook to do the same.

How can i use my old iMac as a extended desktop display for my new iMac?

I recently purchased a 21.5 in iMac and wanted to use my old iMac as a extended desktop. My new iMac has thunderbolt and USB 3.0 connections while my old iMac has firewire (400 and 800), USB 2.0 and mini-DVI. Is this posible?

Welcome to Apple Support Communities
If your iMac has got Mini-DVI, you have a 17, 20 or 24-inch iMac that doesn't support Target Display. Late 2009 and Mid 2010 27-inch iMacs, and iMacs with Thunderbolt can be used as external displays. Read > http://support.apple.com/kb/PH11302?viewlocale=en_US&locale=en_US
If your old iMac doesn't support Target Display mode, you can use ScreenRecycler to use your old iMac as an extended display for the new iMac. The only thing you need is that both Macs are connected to the same network

HT5019 If my second display is not showing up on the graphics display window, yet the second display is showing a mirror image, how can I get it to recognize the second display and allow me to setup extended desktop?

I'm running 10.9.2 on a Power Mac from 2013. I am using two identical HP monitors. I have a Y adapter to connect the monitors. Which I'm guessing means the computer is only seeing one display since there is only one display output.

There are no PowerMacs from 2013. The desktop tower from 2006 on got named Mac Pro. The problem is probably the Y adapter. You need a videocard with two display ports, or two videocards to be able to make an extended desktop from one to the other. If you gave us the Y adapter make and model, we could tell if it supports screen spanning or not.

Using a second computer (an iMac) as an extended desktop monitor

Hello
I have a powerbook g4 and would really like to use a separate older iMac as an extended desktop. Is there a way to turn the iMac into just a monitor recognized by my powerbook?

Does ScreenRecycler do what you want?

Macbook Pro Retina: can anyone help me with running 2 extended desktop DVIs?

I know I need 2 thunderbolt to DVI adapters for this. In the UK these are £25 each, but the MiniDisplayPort to DVI adapters which look the same are very much cheaper .....
http://www.amazon.com/DisplayPort-Female-Adapter-Macbook-Laptop/dp/B003BHHIA4/re f=sr_1_1?s=electronics&ie=UTF8&qid=1359830910&sr=1-1&keywords=minidisplayport+to +DVI
They look the same as thunderbolt to DVIs but is there a difference? Anybody know if the thunderbolt to DVI is an ACTIVE adapter, which means the cheaper versions won't work?
Secondly, I've read scary stuff here from people who think their thunderbolt to DVI fried their monitors. Is there any evidence which supports this?
Does anyone out there use two extended desktop DVIs on a daily basis with a Pro Retina? Any tips or things I should know?

I suggest you buy the Apple TB/MDP to DVI adapters as I have tried another brand and it dod not work. That was on a late 15" 2011 model, YMMV.
Second I have never heard of a Apple TB/MDP to DVI adapter ever frying a monitor of any make or model.
Please post references to this claim.
May be possible with a poorly desinged adapter with some of the TB power output being cross linked to one of the DVI pins/connectors. But still doubtful.

Mac Mini (mid-2011) dual display with extended desktop

Is it possible to assign an extended desktop to be an external desktop for a window's machine?

I have an iMac with Lion and a Windows Vists Laptop and corresponding external monitor on my desk. I'd ideally like to use my iMac as an external monitor for the Window's machine and essentially remove the physical one from my desk. Make sense?
I already have 4 extended desktops created on my iMac and I'm HOPING that I could assign Desktop 4 (example) as the external monitor to be controlled by the Vista machine. I'd like to be able to flip between my Mac OS and the "extrernal monitor'' via the 2-finger-swipe gesture. Anyone have any ideas?
NOTE: I also have Paralles installed with Windows 7 running on my iMac, but I specifically need the Vista machine to have the external monitor, so please do not suggest this solution.

Thank you! While reading these directions, I realized that I have the wrong connector. I have the old Mac Monitor serial port to VGA instead of the MiniDisplay port to VGA needed (didn't even think about this computer not having that port available). I just bought the correct one from Apple, so I'll attempt these instructions as soon as it arrives.
To confirm: I'll be able to run the iMac as the external display and have Lion open simultaneously, right? (Obviously not both on the screen simultaneously, but the ability to "switch" views) Based on the article, the trick is turning the Target Display on/off with the Command + F2 buttons (as opposed to assigning an extended desktop and using gestures), correct?
Again, thank you for your help!

Dual Display, 2 Monitors - Extended Desktop

Hello Everyone:
There isn't a clear cut answer or solution in connected a Macbook Air to 2 external monitors in an attempt to create an extended desktop. I have read older posts that it's either doable or not doable. My questions are the following:
-Is it possible to connect a new Macbook Air to 2 external monitors for extended desktop purposes?
-Some users have reported lag issues (mouse dragging , delays, etc.). Will this happen for sure with a Macbook Air or is it a monitor issue?
-What's the best non-Apple monitor brand that would work best with a Macbook Air for dual display purposes? I've read that Dells have a problem in this regard.
-What would be the advantage or disadvantage of using a dock station in setting up a dual display environment? Would this add to the lag, latency factor?
I'm thinking of investing in a new Macbook Air, but I want to make sure I dont end up with silly issues - such as latency, monitors, etc.
Thank you for all your help and advise.
Best,
G.

Yes, extended desktop works with monitors set to differant resoultions. the Monitors pref pane allows you to select relative arrangements and rez of all monitors composing the extended desktop.
personally I run a dell CRT at 2304 X 1728 @ 60Hz along with an NEC 6FG a 2048 X 1280 @ 60Hz off a radeon 9800pro on an MDD.

Airplay display issues: "extend desktop" not working properly. Secondary display continues to mirror.

Whenever I turn my airplay display on and set it to "extend desktop," my secondary display (TV) continues mirroring my mac book pro (hereinafter MBP). It doesn't fully mirror my MBP, but my secondary display registers every time I switch between my desktop 1 and my full screen apps. Moreover, When I do switch to a fullscreen app on my MBP, I get a blank (blue-ish) screen on my TV.
Any solutions!?!
Additionally, "extended desktop" for my Airplay display worked properly when Mavericks was first released.

Try this:
Click on the Apple TV Icon on the top toolbar
Then, select "Mirror Built in Display" instead of extend desktop
In the same menu under "Match Desktop size to:" select "Apple TV" (or keep it on "built in display if that works"
This solved a similar problem for me.
