10.5.1 and dual display bug

I have been using my MacBook Core Duo (graphics card GMA 950) connected to a projector in dual display mode for over a year. After upgrading from 10.5 to 10.5.1, the macbook can function in mirror mode, but the projector does not receive a signal for dual display unless I restart the computer. The problem is consistent even though the projector has not changed.
Normally I plug in and the laptop screen changes to blue, then changes to dual display mode and sends a signal to the projector. Now, when I connect to the projector, the projector signal is black. I can switch to mirror mode using either F7 or via the Display preferences but there is no way to obtain dual display mode. Once I reboot, the problem is solved. This has been going on daily, each time with the same solution.

I get dozens of the "ACL found but not expected ..." messages, all on the contents of System/Library/User Templates/. When I go to System/Library/ in Finder, only the User Templates folder has a red icon on it, indicating that I do not have access to it (when logged in as an admin). The icon does not appear on any of the other folders in System/Library. Does anyone have any idea on what's going on?

T410/T510 and Dual Displays

I'm looking at the T410 or T510 for my wife for her business. I wanted to try and set her up with dual displays (either the laptop LCD itself plus one display or two physical displays. Is there anything I need to be aware of in regards to a dock solution or a discrete graphics card if I'm thinking of dual displays?
Solved!
Go to Solution.

1) the integrated only option supports a max of 2 display by itself, so either 2 external LCD and no internal LCD. Or 1 external and 1 internal.
2) the optimus nvidia gpu supports up to 4 LCD.

Bridge and dual displays

I have been searching the web for a while now to find a way to show the usual Bridge window on one display and a preview - just a preview... no menu bar or other embellishments - on the other display in a dual display setup.
Apple's Aperture does it but I can't find a way to do it with Bridge, nor does it appear that Lightroom will do it.
I think this is a significant setback... being able to do this would be great for editing so you could see the image preview with no distractions and as big as possible. More to the point it would be good for presentations so the presenter can see all the folder structure, favourites, thumbnails etc but the audience only sees the intended image on a clean black (yes black... not the image backdrop colour) background.
I have found a way to cheat this, by extending the Bridge window over both displays and positioning all the favourites, folders, thumbnails panels etc on the extreme right side but you still see the menu bar and other bits and bobs at the window edges and the background colour is grey, not black (unless you set the image backdrop to black, which I think is a bit harsh for viewing thumbnails).
If you want to see what I mean, go to http://www.2020graphics.com.au/dual_displays.html
If anyone has any ideas on how to do this, or any Adobe engineers are reading this... help!!!

>Select an image in Bridge. Then hit the space bar on your keyboard.
 
 This is what you get:

Full Screen Preview Space
 nothing but your image on the main monitor, your secondary monitor totally blacked out.
 
 You can use the arrow keys to navigate through the images in the folder. Use the escape key to go back to regular view.

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.

Dual display bug

seems to be a bug in the display preferences. if i use dual monitors, it does not extend desktop like it used to. you can only mirror the two displays

Since I've updated to Snow Leopard I have problem to use dual screens.
When I boot the secondary screen stay blank. Sometimes the image appears but for a very short moment and then just disappears.
The only way I found to use dual screen is to enable mirroring and disable it. I have to do it after every reboot...

Port replicator and dual displays

Stupid question alert - if the machine stands straight up in the replicator, how do you use the display in a dual configuration? Also, you still need toplug a USB cable in?

Sorry can you explain what you mean if the machine stands straight up in the replicator? Also, which machine are we talking about here and the model of the port replicator?

Screen sharing and dual displays

Hi, i added a second display on an iMac and often screen share using my MacBook but since adding the second screen i've had issues screen sharing. It will briefly show both the iMac's displays on my MacBook but then cut out with "connection lost", then find the connection again, then lose it etc etc. Sometimes i can select just the first display and it'll be fine but usually the connection keeps dropping and firing up so quickly that i can't get it to just show the one screen.
I unplugged the second display and everything worked fine as it always has done. Is this a known issue to be resolved in 10.5.3? If not is there a way i can change the default in screen sharing so that it'll just show me the first display? I don't need to see the second display particularly so that doesn't bother me.
Thanks, Simon

It may or may not be a common problem, since I screen share a 2-screen Mac Pro from a MacBook Pro and have not seen this problem. I always get both screens.

T61 and dual displays

Hi there
I have a T61 which a dock and two external monitors connected. HP L2035 (1600x1200) on the DVI and Dell 1907FP on the VGA.
Everything used to work just fine, until some windows update was installed few days ago. Now I can't get the HP display to work.
When I try to change to that monitor via the directorI get the erro:
The following settings you have selected cannot be applied properly. Change the settings and try again. Notebook LCD Resolution Color Quality.
But when I try to change to the HP display via the nview control pana, nothing happens.
I someone else experiencing this?
I have tried to install the latest Precentation Director for the lenovo/ibm site and also the latest NVIDIA drivers for the Quadro NVS 140M.

Yes i had same error but updating presentation director fixed that error. yes i see that you already tested this but i just wanted to tell if this helps someone else.
or maybe you could try this:
-uninstall presentation director
-reboot
-install presentation director
-Remake display profiles to presentation director.

Cintiq 24 HD and dual display turning files black?

I have a brand new Cintiq 24 HD and a secondary monitor, a 24 inch Gateway. Any files I open in Photoshop show up fine on my Cintiq, but as soon as I try and drag them onto the other monitor, they mysteriously turn black. If I drag it back to the Cintiq, I can see it again. Does anybody know why this is happening?

We purchased two new 24" Apple Cinema Displays a few weeks ago along with a new MacBook Pro 15" 2.66GHz. We are using the Cinema Display's built-in mini display port to connect it to the MacBook Pro. Within a few days of setting up the computer, we've encountered the following intermittent faults:
1. Cinema Display flashes black (completely) for a couple of milliseconds;
2. horizontal white lines (1 pixel to 100ish pixels high) flash across Cinema Display.
The MacBook Pro can go for hours with no problem at all and then start a fit of flickering. The MacBook Pro's internal monitor is not affected by any of this. The problem occurs with the MacBook Pro attached to either of the two new Cinema Displays.
We reported the fault and Apple who provided a replacement MacBook Pro. The new computer is doing the exact same thing. We raised it again with Applecare yesterday and installed a Cinema Display firmware update (OS X 10.6.2). The flickering stopped for the rest of the day, but today it's started flickering again!
We also have a one year old MacBook Pro 15" 2.4GHz running OSX 10.5.8 which works perfectly (no flickering or cutouts) with both Cinema Displays.
Apple have now assigned an Engineer to our case and asked us to install some monitoring software (Capture Data / TimingSnoop). I'll update this post if/when Apple resolve the problem.

Problem with 10.8; MacPro and dual displays

I have a MacPro with 2 video cards each running a separate Cinema Display. It worked fine with 10.7.
Now with 10.8 the behaviour is very erratic. The displays get L-R reversed. Even when I reset them using System Preferences>Displays and close that (presumably saving the preference), sooner or later, if I do a restart it will reverse back pattern. No particular rhyme or reason to this that I can see. Even physically moving the monitors L<-> Rt doesnt help and sooner or later it changes again. This is a major irritant with 10.8
Any suggestions?

That's a question better suited for Microsoft, but certainly has nothing to do with this forum for the Mac App Store.

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

Geforce 4 mx 440 dual display - mandrake 9.0

[size=11]
I am wanting to switch my workstation from Windows 2000 to Linux Mandrake 9.0. Anyone tell me if all of the TV in/out and dual display stuff will work under Mandrake 9? It is the GeForce 4 MX 440 with the dual VGA out and the s-video input/output connections. The main concern is the dual display. Let me know at [email protected] or post here. Thanks for the help!

A previous poster (in a different thread) found that if the video card has both analog and digital monitor outputs, then for TV-out to function properly with the VIVO 4-port adapater, you need to connect your analog monitor to the digital output using the supplied digital-to-analog converter.
I have a new G4 MX440 VTD8X and had a similar issue to the one described here....the TV could not be detected by the video card when connected via RCA jacks (S-video worked, but could not CLONE the monitor). I moved my primary monitor from the analog to the digital port, and viola, the TV out functions perfectly now. :D

Photoshop CS4 Menu toolbar display bug and fullscreen slowness...

http://img384.imageshack.us/img384/8202/menutoolsbugee3.gif
I'm having a display bug with the menu toolbar in Photoshop CS4 Extended. Notice the area of tools is gone and replaced by random pixels? This happens whenever I enter the fullscreen mode that hides the interface. And when I exit that fullscreen mode, that bug appears and doesn't fix itself until I restart Photoshop. Can this be fixed?
Image view rotation also happens much slower than normal in that fullscreen mode when interface is hidden. But performs normally after I bring back the interface.
I'm on WinXP, Athlon 64 4000+, 3GB ram, GeForce 6800 GT video card [driver 169.21]. I'm not sure if this is a video driver bug or CS4 bug.

Yeah, Dave, I can understand how that can happen. I've seen that sort of weirdness when I've seriously overtaxed my hardware.
 
 Had way too much running all at once yesterday, switched over to Firefox, and clicking on folders in the Bookmarks bar, I had 4 bookmark/folder menus dropped simultaneously.
 
 I managed to grab a screenshot with 2 of them showing, but man! You shoulda seen it with 4!
 
 I ESC'ed out, quit GarageBand (had a song project of several hundred MB going) and all was fixed.

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 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
