Dual Displays (Fooling Keynote)

I read something online and I can't find it anymore. What I'm looking for is how to "fool" my Powerbook and Keynote into thinking I have dual displays so I can test out my presentation's presenter options.
I know it had something to do with attaching the dongle, changing the System Preferences and Keynote Preferences. I also remember that things had to be done in a specific order. I have tried a few combinations, but none of them work. I've also searched the web with not luck.
Does this ring a bell with anyone?
I'll be presenting Monday morning at a convention from my laptop with a projector that will be set up in my classroom. Unfortunately, I won't be able to practice until 1 hour before my presentation.
Thanks!

Welcome to the forums, renee.
Do you have Keynote 3? If so, simply go to the View menu and choose "Rehearse Slideshow". That view will let you see the show as if you are viewing the Presenter Display.

Hyperlinks in Dual Display mode, Keynote '09.

This problem has been well reported in this forum,but I cannot find an answer.
I have created a series of Keynote '09 presentations and I have installed hyperlinks on the last slide of each one to open, on clicking, the subsequent presentation.
Trouble is in Dual Display (not mirrored) mode using a projector as Secondary Display and a MacBook as Primary Display (with next slide, presenter notes, timers, and other items that only I, as presenter, can see. Then I cannot activate the hyperlinks; in fact the icon of small blue circle and white arrow is not showing in this mode and the pointer does not change to finger.
However if I press X or use "Swap" from drop-down menu I can see the view of slide that the audience normally sees and the hyperlink is shown and active. I click on it and once the subsequent Keynote opens, I can press X again and return to Presenter View on MB, but this is messy and the audience gets to see the "workings". Not a good look.
Interestingly, the same disappearance of hyperlinks also occurs if I use Rehearse Slideshow, but not if I use Play Slideshow when MB is not hooked to external display. This seems to suggest thst these hyperlinks are not there in "Presenter" view.

I found I had the same problem at my let presentation: Hyperlinks do not work in dual display using the MacBook at primary display. I gave up and put the presentation on my iPad and everything worked fine. Think I will just mirror the display of my MacBook so I can use the hyperlinks.

Mavericks and Dual Display not working as documented

Hi all. Ok..something a little wierder here for my dual display scenario. I have two Samsung Syncmaster 2443 monitors. 15" MBP Retina purchased this year. Running in Clamshell Mode.
I can get dual monitors happening (extended) but I cannot get the menu bar to come over as well. As mentioned in other posts, I need to tick the box in Mission Control "Displays have seperate spaces". The only problem is, that particular menu item is NOT there. All I have is the other 4 items. So how is it that this menu item does not exist on my installation?
In this current setup, each time I reboot the display's also get reveresed, which is really annoying. I have to reboot twice to get back to my original layout.
Any idea's?
Tks

you're faking out your machine to THINK it has 2 real displays and you expect Keynote to work? Keynote is THE most intense app I've ever seen for screen drawing. It basically takes over your entire machine to do its work. It doesn't surprise me that that trick doesn't work with it.
My guess is you're going to have to wait till you have the actual projector and adapter to test your dual screen setup.

Wacom tablet on dual display dual card setup...

...and the cards are as follows, one Geforce GTX 460 (nvidia driver), one Radeon x1650 (radeon driver) As such, I have to use Xinerama and not RandR for my dual display setup. I have configured the driver to use my main display (Dell CRT on GTX 460) and the cursor shows up where it's supposed to, but when I draw, the cursor "splits" into two, the actual cursor, and the drawing cursor. The regular cursor moves as if it's on my main display, but the drawing cursor spans both desktops.
I've tried all kinds of things to make it work, no luck though.
xsetwacom set "Wacom Graphire4 6x8 stylus" Area 0 0 30408 12064
xsetwacom get "Wacom Graphire4 6x8 stylus" MapToOutput HEAD-0
Both of those commands produce the same result, which is shown in the video below.

And a lovely video showing what I mean.

Any help would be lovely.

MisterAnderson wrote:Honestly no clue how to help you, but I am interested in your setup. Are you using the proprietary drivers for your nvidia card and the opensource radeon for your ati? How did you get this setup working? I've been trying for ages!
If I remember correctly, I just used --nodeps and maybe --force when installing the nvidia driver, that way it didn't force me to uninstall the radeon driver when I install the nvidia driver. Then, look at my xorg.conf. there's no acceleration of any sort on the ati card, but I can use it for terminals and browser windows, text editors and the like. Can't watch flash videos on it though, and I don't think mplayer works on it either, I'm not at my arch box atm, so I can't verify that.
Also, as mentioned in my opening post, no composting either. The same setup works pretty good in Ubuntu with a similar config, but no compositing there either, Unity clones 1680x1050 of my main 2048x1536 display, can't split the desktops, and I just end up using Xfce4 because it handles Xinerma pretty well.. I have to turn off the compositing extension in the config on arch to get X to even start up.
:edit:
back in arch, should note that whenever I install a new package, I receive this warning. Everything still works tghough as I describes. And back on topic, anyone have any clue as to why my tablet behaves this way?

According to the copy&paste from wikipedia, HDMI should support higher resolution than 1920x1200. So the question is, does it aupport that on the mid 2011 mac mini. It says in the specifications
"Mac mini is designed to work with HDMI devices that comply with versions 1.0, 1.1, 1.2, 1.2a, 1.3, 1.3a, and 1.4 of the HDMI specification."
That should mean it should be able to support it, but I don't know : <

How do I use dual displays to have a full screen app on one monitor and another full screen app or the desktop on the other?

How do I use dual displays to have a full screen app on one monitor and another full screen app or the desktop on the other?
I want to have my itunes visualizer on my TV which is connected via HDMI adapter, and still have access to full screen itunes and my desktop on the main display.
Any suggestions? App downloads that can do this? Please let me know.

You can't do it. This has been an issue since Lion.

Dual display color and other related issues...

I have posted this on painter forums, though some of the issues coming together here are directly related to issues w/ Snow Leopard and dual displays. Thought I would try here....
This is so bizarre. When I ever I run P11(I think this is going on in P10 too?) w/ the OS X (snow leopard, 10.6.2 on quad core Intel Xeon Mac Pro, 10 GB of RAM) menu bar on my Eizo(making it the main display), and the Apple Cinema display left as the #2 monitor, I get very annoying brush cursor artifcats left randomly on the Eizo screen after strokes. One cannot predict when the cursor will leave it's gray "marks", but it will do it, sometimes 5 strokes in a row, sometimes after 15 strokes or so? If I move my brush back over them, or change the image percantage view, they vanish, obviously new ones coming back, as I work.
However I put the OS menu bar on the AC display, yet work back on the Eizo, this does NOT happen. No cursor artifacts. Well, at least I can summon the issue
The reason I am doing this is Snow Leopard has bad color issues w/ dual displays (well documented, much to Photoshop CS4 users frustrations, and mine). Apple needs to fix it... but for me to see the right color on the Eizo(this is my main color and superior display), it needs to be the main monitor(menu bar) in 10.6.2.
So, you can see my trap - Accurate color, or annoying cursor artifacts left on the screen (sorry, it really bugs me as I work) as I work in Painter.
Attempted fixes: Trashed all of Painter's prefs, all of Wacom's Intuos 4(latest driver) prefs and software, switched plug ins on the back of the mac for the displays(lots of restarts), ran cache cleaning Cocktail and DiskWarrior, etc. -- no change, as I can duplicate the issue w/ the above set up. A sidebar or maybe be very related note: I have an iMac w/ max amount of ram (model not very old -- maybe 1 or 2 old) and I have had a long standing issue working on the iMacs we have had w/ this brush cursor artifact problem (in Leopard and Snow Leopard). I am on one monitor w/ the iMac, so you know here the menu bar is...hmmmmmmmm.....?
Thanks!, T

Possible to do dual display with a mini?

I have an early 2008 Mac mini (Intel) - with the standard DVI connector; using the supplied DVI/VGA adapter to connect to an LCD monitor.
I'm just wondering if it is possible to use two displays with this model and if so, how do I connect the second monitor?

Several ways of doing it in this thread:
http://discussions.apple.com/thread.jspa?messageID=8335705&#8335705
If you want to go the usb route, see also:
http://eshop.macsales.com/item/Other%20World%20Computing/VIDU2DVIA/
Be sure to examine the limitations of each method.
(I'd also consider that your 2008 Mini likely has substantial resale value and that you might prefer getting a 2009 Mini which natively supports dual displays.)

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

Are you using splitter maybe?

Dual Display on Mac Mini

Hi there,
I want to have a dual display setup with my Mac Mini. There's also a twist. One of the displays is a regular monitor. The other display is a 46" TV. I am not too technically minded - is there a splitter or some kind of dual display "kit" I can pick up?
Thanks!

Which Mac mini? The new one has two video outputs on it, so two displays is not a problem.

Dual Displays and Windows XP

Hello,
I have a MBP with the Radeon X1600 graphics card. Under OS X I can run dual displays without a problem, either extended or mirrored. Using Bootcamp to boot to Win XP, I can only get the 2nd monitor to run extended, I can't get it to run mirrored. What really drives me nuts (short trip) is that I have run it in mirrored mode before when I teach. I go to the Display dialog box and "see" both monitors, but the only way I can get anything now on the 2nd is to run extended? I could update Radeon driver on the Windows side, but I thought BootCamp took care of that and I don't want to mess up my laptop?

It is definitely best to reinstall anytime you make a major system change. You will have to do at least a windows repair although I am not sure if it will fully enable the dual core.
Good Luck
Jeremy

Dual Display - help with Cinema Display for MacBook Pro where MB won't detect displays.

I just got a Cinema Display (a1081 20") ("CD") off eBay to use as a dual screen with my Macbook Pro OS X 10.6.8 ("MB"). However, I can't get MB to recognize CD! I've tried power cycling both the MB and the CD with and without USB cord connected. MB won't recognize CD display in any situation. However, it is recognized in some capacity although I can't use dual display because the CD power button triggers MB to ask me if I want to restart, shutdown, or cancel.
Any help is appreciated!!

Have you tried smc and pram resets?
Try Detect Displays in the Displays preference pane.
Does the Displays preference pane Arrangement show two screens? If so do click gather windows and check the resolution setting of the new screen.

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.

Mac mini dual display - blue screen flashes frequently

I recently purchased a mac mini i7 model, with fusion drive.
I have upgraded the RAM to 16GB.
I have also purchased 2 monitors, both are LG 22EA63V LED.
I connected one monitor direct HDMI to HDMI.
The other monitor is connected from Thunderbolt to HDMI.
Everything worked amazingly well for the first few weeks. Now, not so much....
I frequently have the screen freeze and flash blue, and then resume as normal dual display mode.
Other times the screen will flash blue and then come back as a single display. In this case the Thunderbolt to HDMI display appears as primary display, while the HDMI display loses connection.
If I unplug the HDMI display completely, the blue screen flashing does not happen at all.
So, what could be causing this problem, and how do i fix it?

Hi Matt,
See if there's some setting on the HDMI monitor for Input Source, or things like Auto-tune.

Dual Displays, not enough firewire ports?!

My MacPro isn't here yet...and I only have 1 cinema display right now but plan on adding a 2nd one in a few months.
In my anticipation for the Mac to be dropped of by FedEx, I noticed something while reviewing the specs...
My video card, the ATI Radeon X1900, has two DVI ports (so I can do two 23" or whatnot). If I use the my 23" Cinema Display, I can plug in the USB, the Firewire & the DVI connector.
However!! If I get a 2nd 23" Cinema Display, there's room for another DVI port and USB but NO firewire port. There's only ONE 400 FW port on the back of this machine?!?!
What do you all do if you're dual displaying it w/ Apple displays??

Well, the Firewire cable/port in the monitor is only there as a hub/extender, it doesn't affect the working of the monitor itself. So you can always attach the cable from the second monitor into the Firewire port of the first monitor. It depends how many other Firewire devices you need to add.
