Tri Extended Desktop?

I want to buy a macbook pro for college and I currently am running a dual display on my windows machine with two 19 flat lcds. I know the macbook has one dvi out but is it possible to get another external monitor attached with a usb or firewire converter box? If someone could please let me know how many monitors the macbook pro supports i would appreciate it seeing how if i used my two 19ins and the macbook pro display i could be running a tri extended desktop. Thank you in advance!

Hi, i think u can get a Matrox DVI splitter that can allow u to further split the DVI output into 2 LCD.

Trying to use extended desktop

I typically use my 13" MBP with a 20" LG monitor in extended desktop mode. I would regularly plug in my computer when I got home to do work, and unplug it when i left the next morning. I hadn't used extended desktop for a few days, and the next time I plugged in the monitor, it came up with weird resolution with a different aspect ratio and an off center picture. The option for 1600 x 900 at 60Hz isn't listed in system preferences anymore. Do I have a hardware problem here?
Note: I did switch to a shorter VGA cable to reduce clutter on my desk before this problem occurred, but I can't get extended desktop to work properly with my old cable, so I don't think its a faulty cable.

OK open System Preferences/Displays and click the Colour Tab
Does a Profile appear in the left hand column that matches the name of your external monitor ?
If others appear try selecting one of them and then going back to the first
Uncheck "Show profiles for this display only' then try selecting some alternatives to see if this kicks it into action.
Also, try selecting the display profile then clicking 'Calibrate' and run through the adjustments and see if that brings it right.
If none of those work try /Utilities/Colorsync Utility and click Profile First Aid then Repair.

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.

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.

Portege m700 Tablet Extended Desktop Problem

I've looked all over and can't find a good answer to this, so I figured I'd better check with the source! I have a Toshiba Portege m700 tablet PC, which has an LCD monitor connected using the digital cable.
I have the external monitor set as my primary, with the notebook monitor set as the secondary, providing extra desktop real estate to the right of the first monitor.
The problem is that when I use the touchscreen, the mouse controls are only active on the primary monitor (the external one). What I'd like to do is have the external monitor be primary, the notebook monitor be secondary, and be able to drag items to the notebook and use ink, or onenote, or other touchscreen apps on there. I want the touchscreen to control ONLY the secondary (notebook) monitor. Is this possible?
It seems like there should be some way to just instruct the computer to map the touchscreen to the secondary monitor instead of always just mapping to the primary.
However, if there is not, what I did experiment with is having the notebook as primary and the external as secondary, and then using some sort of multimonitor software to manage the taskbar and such to create the illusion of the external monitor being primary. The problem here is that while the notebook is 1280 x 800 resolution, the external monitor is capable of 1280 x 1024, but when set as secondary will go no higher than 1280 x 800. Is there a way to force the external monitor to run in 1280 x 1024 if I'm using it as the secondary?
Is this something for which I need an updated graphics driver? I tried to get a newer version of the Intel GMA, but it actually removed all extended desktop options for me, so I rolled it back. The version it's running is 6.14.10.4837.
Thank you in advance for anyone pointing me to any driver updates, configuration directions, or external software that can effectively manage all these options of extended desktop, screen resolution, and what monitor is assigned to touchscreen control!

I've just tested the "Extended Desktop for Tablet PC" powertoy, and that doesn't solve this problem. With the tablet set as the secondary monitor, when I move the window onto that screen, it just recurses the image over itself, which isn't really useful.
No one has any other ideas about this?

Setting Up Extended Desktop

I am trying to set up an extended desktop for my iMac. The operating system on it is 10.6.8 and I am trying to set it up so that the extended desktop utilizes my Macbook Pro system 10.7.5. I have the thunderbolt cable and have connected it to both computers and tried the following:
System Preferences -> Displays -> Arrangement
However, when I go into system preferences there is no option under displays for arrangement. What am I doing wrong or what should I be doing to make this work? Is it even possible? Thank you.

There is no MacBookPro model that I know of that you could use as an extended desktop for your iMac. I don't think any MBP's ever supported use of the MBP as a display for another computer.
Only certain iMac models support(ed) their use as a monitor for another computer connected to it via miniDP. If you have such an iMac, you may be able to use it as an extended desktop for your MacBookPro, but not the other way around.

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.

Extended desktop lows resolution

Hi all.
First of all i would like to thank you for helping people like me to solve their problems all around the world.
Did someone experiencied this?
I couldn`t set an 85HZ when my resolution was at 1024 * 768 and 32bits color quality. So I tried doing everything I find in this forum and in the nforcershq forum... nothing seemed to work... and finally........ in one try of uninstalling and installing de nvdia drivers, I uninstall the second monitor listed in the device manager, so when I went to the display properties I didn`t have the second display active(Extend Desktop in this device) and 1024*768*32bit*85hz AVAILABLE. There was the simple answer, when activating the second device(TV in my case)the first device(monitor SyncMaster753DFX)refresh rate lowed from 85HZ to 60HZ with no other choices.. the only thing I could do was to turn to 16 bits color Quality to get back the 85Hz rate.
Does someone understand what is happening?
Does anyone know if its possible to correct this situation?
Tanks in advance.
I have a K7N2G-L and 512DDR266PC2100(spectek) in slot 3, XP SP1

if i understand correctly, yes this did happen to me. i believe this happened when i installed the gpu drivers from the msi site. my refresh was stuck at 60hz. i was able to solve it by changing from -clone- to -standard- in display props. now use nvidia unified drivers with no above problem.

Extended desktop issue

I've tried to run extended desktop from macbook air while connecting it with an external monitor. But I can't control or move the cursor to the external monitor when there is a window popping on the external monitor. Thanks.

Go to System Preferences -> Displays -> Arrangement
and check/adjust the positions.

NB305-106 - Display driver for extended desktop

I would like to know if there is a display driver or any way possible to have "Extended desktop" with my NB305 rather than cloned dual display?
Thanks in advance.

Hi there,
Yeah thats the first thing I tried. However the extended desktop is not showing as an option, only dual display clone.
The display version was 8-----1972 so updated to the latest driver from Tosh support but still no extended desktop option.
A little frustrating as I have a really old Dell laptop with xp on running two external monitors as extended desktop.

Two w2408h monitors,extended desktop..2nd not recognized at cold start?

Hi All:
HPe9180f with Vista 64 bit Home Premium.
I have two HP w2408h monitors, purchased and installed on the above computer,when new. I have tried Tech Support who have certainly tried to take "ownership" of my issue, but with no solution, I have given up.
My issue is that I can work correctly with both monitors, extended desktop mode, if I never shut off my computer....if I do, the second monitor will not turn on during a cold start. My workaround, discovered by accident, is to log on in a non-admin user, wait until all programs, etc are loaded and then Restart....my second monitor then activates. Does anybody know what to do to do to make Windows/ Bios recognize that I have two monitors permanently in use at all times, especially at startup?

GC, I would search for an updated driver for you video card/chip. This sounds like it may be a driver problem. Video and Audio problems are very difficult to diagnose from afar. So, I always begin with the most obvious solutions. Just call me "Mr. Obvious".

Mavericks AirPlay Extend Desktop as FCPX A/V Output?

Hi all,
Has anybody been successful at using the new "Extend Desktop" mode for AirPlay in Mac OS X Mavericks to setup an AppleTV as an external monitor for Final Cut Pro X? I tried but when I go to Preferences...->Playback A/V Output says "None Found". I just think it would be a convenient, inexpensive way of leveraging the AppleTV as a monitor.
Any ideas?

Thanks Luis. As you say: "more or less". Besides the lag it's also a bit buggy. I had to switch applications a couple of times for the viewer to show and respond. Also, full screening the viewer make the main monitor go all black, so you can't really have a full screen viewer and the interface on another screen. At least I couldn't figure out how. But this is better than nothing I guess. Thanks for the tip!

2 extended desktops on macbook pro?

Hello, I am using a MacBook Pro 13" Mid-2012.
What I am trying to do is get 2 seperate extended desktops (one on the left, one on the right).
The displays I am using are: HP 2011X Monitor and Haier 22" LED TV
I have this adapter device: I14-42285_chiclet01_gfv_mn_3429793.jpg
Now, when I connect the two displays to the macbook, it recognizes them as one unit and I am left with a mirrored extended desktop (with compromised visuals).
Alternatively I can attain 3 mirrored displays of the visuals on the macbook pro. None of these two options suits my needs.
Is there something I can do to configure the two monitors, as 2 seperate displays, to be used as 2 seperate extended desktops? or as 1 entire extended desktop? (as opposed to mirrored)

^That's what I want to do!
It's a .gif (please click)

My Airplay is delivering Audio but no Video (black screen). The drop down box has a new selection "use airplay to; it does not let me select 'Mirror my IMac', it is stuck on 'extend desktop' any suggestions appreciated.

In response to below------Thank you Lynn-----Yes, there is a main panel--I will attach----and if you have any further suggestions please let me know--Thanks again
How are you running this program? Is there a top level vi which calls the ones you posted? The Display image on screen.vi will display two images in succession, but according to the note on the block diagram the second image is blank. It seems as though this would intentionally create a flicker.
The sequence structure is unnecessary. Dataflow will determine the order of execution. The only exception is the time delay in the third frame. Since it has no data dependency, a single frame sequence may be useful to assure that the delay occurs before the picture is updated. A simple state machine might be a more versatile architecture for what you may be trying to do.
It is not necessary to write the FR.PanelBounds property immediately after reading it, nor is it necessary to read it a second time in the second frame. Just wire from the first read.
