Windows 7 and Multiple Monitor Issues

Alright, I have spent the past 3 days searching these forums as well as on Microsoft's support pages and all of Google to find the answer to my issue and it seems as though I'm the only one who is running into this problem.
I have a 15 inch Macbook Pro with the GeForce 9600M GT Nvidia Graphics card with the latest version of Mac OSX and Bootcamp installed on it. I have Windows 7 installed in bootcamp. I just purchased a Mini DisplayPort to VGA cord with a VGA cord so as to connect my computer to my Sony Bravia HDTV to use as a second monitor. I plug in the cords, plug them into my TV, and put it into the proper input and it works like a charm. Then I go and boot up in bootcamp under Windows 7, plug in the cord, and my screen gets to the "starting windows" logo and then it goes black. I push ever button, I try control alt delete, nothing. I have to hold down the power button to turn off the computer and then turn it back on.
I turn it on, boot up into Windows 7, let it load, then plug in the cord, and the computer display instantly goes black, again, and yet nothing displays on the TV. Again, I try everything to no avail, so I power it off and back on. I go through this at least 10 times to no avail. I finally give up and try again the next day.
Next day, I plug it in, and the monitor stays up, but yet nothing is displayed on the TV. I go to my resolution settings in Windows, and go to the multiple monitors tab, and select every possible option (extend, duplicate, etc) and nothing will display on my TV. I try to change the settings to which it responds with "unable to save display settings" and nothing changes. I attempt to enter the nvidia program and make changes that way. The TV is detected, but when I select it and attempt to apply anything, no changes take effect and I am left with only the laptop display. Keep in mind I uninstalled and reinstalled all of the video drivers and such.
Finally I get fed up so I purchase a Mini DisplayPort to DVI adapted and a DVI to HDMI adapter. I try again. Again in OSX it launches immediately, no problems. I go back into Windows, and immediately I'm dealing with the instant black screen.
I'm going crazy over here trying to figure this out. I know it's possible to do this because I've seen people on youtube doing this and again it works on OSX so why the heck won't it work? If anyone has any idea what's going on here please help me out. Thanks.

JonMarx... I'm having the exact same problem. I'm in the exact same situation as you are. I'm going mad, and it's only by divine providence that I've finally located the only other person who knows what I've been going through. I've spent at least 20 hours trying to get this started back up, to no avail.
I had the secondary display working peachy for a while, long enough to configure everything to be exactly how I wanted it. I unplugged the monitor from the computer just to see what would happen, and that's when the problems started. I managed to get it to work one last time for a brief period a few hours later, but the way it just clicked on made it feel too good to be true.
I've had a wierd problem with a phantom display as well. The display will frequently show up as being available in both the nVIDIA panel and the windows settings, but if I apply the settings, they won't go through. I got a few screenshots of it the last time it happened.
I was just about to reinstall windows completely, but it seems that I'll just run into the same problem again if I do... Here's to hoping a solution is found.

XFCE window buttons (tasklist) and multiple monitors

I have dual monitors and each has their own xfce panel with its own set of window buttons. The window buttons have an option to display windows from all monitors, which I don't want, so I deselected it. The only problem is both of the window buttons display the window buttons from the first monitor and not the second. How can I rectify this.

Hi, Rob, Andrew Wolfe here, now working at Interactive Data Corporation in Bedford MA.
I filed some bugs or ERs on this some months ago from Oracle. With very large or multiple monitors, there is a fundamental UI problem with the Microsoft-originated "Multiple-Document Interface" model in which an application's document windows are all enclosed within a main backdrop window.
As a longtime Mac user I have always been amazed that most Windows users work with a single document maximized in a single application window that is maximized over the whole screen. That is, Windows users actually don't use windowing; they use something more like screen swapping. JDeveloper (who knows maybe it's Swing too) buys into this big time by orienting the entire UI around the main JDeveloper window. The tabs and tab groups don't help this at all -- especially given that they always try to dock on you and maximize.
Now Windows UIs have alway squandered screen space -- I'm sorry, does everything really have to have three levels of bulky tool bars? -- and so when displays were smaller (800x600 or less) this way of working made sense. In fact, Windows wastes enough space to exhaust a 1024x768 monitor on a single window.
But when you get any larger than 1024x768, or when you add an additional monitor, that background MDI window is a complete waste, and document windows/tab groups docking and maximizing does not good whatever.
PLEASE allow JDeveloper to run without this backdrop window. Let users move and size tab groups however they like. Preferably this would be a user preference, so I don't have to be CTRL-dragging all the time.
Best,
Andrew

Touchsmart and Multiple Monitors

Has anyone out there actually connected an HP Touchsmart to multiple monitors? I am aware that USB-to-DVI or USB-to-VGA adapters are required. However, I learned from one adapter manufacturer out there (StarTech) that there are known issues with these adapters and the Touchsmart. Has anyone had success? esp with synchronizing video? What brand/type of adapter did you use? My goal is to get one Touchsmart and 4 extra monitors working together. thanks

When requesting assistance, please provide the complete model name and/or product number of the HP computer in question. HP/Compaq makes thousands of models of computers that are all different. Without this information it may be difficult or impossible to assist you in resolving your issue.
You shouldn't need to disable the "Touch" feature to enable "Extended Display" mode... however if don't disable it, you may have issues getting to the extended display or you may experience unpredictable results. Using a mouse should allow you to reach the alternate screen. Depending on your hardware, there may or may not be an option to disable "Touch (Use your finger as an input)" in the Windows Control Panel. You can, however, disable the touchsceen input device in the Windows Device Manager as shown below;

Unable to save display settings and Multiple Monitors

Have Windows 7 RTM installed on my laptop and was working great with extending to my monitor. I took my laptop home and hooked it up to my tv and it was fine. Now when I bring it back to work I cannot get the monitor to work. Only the display on the laptop is working. Windows can detect the monitor, but I try to enable the monitor and when I select Apply I get an error message "Unable to save display settings". I am a local administrator on the laptop. How can I extend to my monitor!
Thanks

Hi,
Error message " Unable to save display settings" mainly indicates that you try to extend or duplicate the desktop to the two external monitors in addition to the laptop screen. Generally, laptop supports only two displays at one time due to hardware limitation. I
suspect that the issue occurs because the laptop remembers both configuration for your extended monitor and TV. To extend your monitor, you need to clear the multiple configuration for your laptop and then extend your display by changing your display
settings. To do this, please take the following steps:
Step 1. Delete registry key.
==================
1)Press Win + R to open a run box.
2)In the Run box, type regedit, and then click OK.
3)Locate the following registry subkey:
HKEY_CURRENT_USER\Software\Microsoft\MobilePC\TMM
4)Right-click the subkey that you located in step 2. Then, click Delete.
5)When you are prompted to confirm the delete operation, click Yes.
6)On the File menu, click Exit to exit Registry Editor.
7)Log off the computer. Then, log on to the computer.
Step 2. Extend your display by changing display settings.
====================================
1)Open Screen Resolution by clicking the Start button , clicking Control Panel, and then, under Appearance and Personalization, clicking Adjust screen resolution.
2)Click the drop-down list next to Multiple displays, click Extend these displays, and then click OK.

This registry key does not exist in my Laptop and it still won't work. I have an Asus N53S
which has both Intel HD Graphics 3000 and an NVidia GeForce GT 540M. It appears that the limitation is actually there is no D-Sub / HDMI / Internal Monitor option like there is in Windows Display.

Windows 8 on multiple monitors

Is there any way to make the windows 8 start screen STAY active on one of the monitors while working on the others? If not the start screen is just a horrible waste of space and time for me and countless other users who will have this same issue.
Also is there a way to make the start screen boot onto a monitor that is not my main? This needs to be implemented as it is an annoyance every time I boot up my computer.
I know this is an issue for many users already and I think this is a very needed addition to make any kind of use of the windows 8 start screen with multiple monitors.
Thanks for your time.

Actually, I do agree with that. I've adopted Windows 8.1 for use at my software company because I believe it has enough merit to warrant upgrading. But I did it only after having spent a LOT of effort to determine that it A) does everything
we need for an engineering workstation and is stable and B) can be augmented to be pretty much as pleasant and productive to use as Windows 7 was
on the desktop. Of course this keeps us "current", so that we keep up with security and device driver development.
My broad point above, which Bob refuted in the details, was that the Win32 interface isn't much different at all than from within Windows 7. We kind of expected Microsoft to further their work on all fronts - making the "legacy desktop" side
actually better AND implementing the new Metro/Modern side - as well as improving the kernel under the covers. Instead, Microsoft seems to have thrown ALL its attention to Metro/Modern, while all but neglecting the kernel and actually deleting
things from the desktop interface. This has folks understandably irritated. Icing that cake is the fact that the Metro/Modern interface has been pretty much a moving target, because clearly Microsoft didn't think through the design of everything
it needed to be before deciding to use it as a basket for all their eggs. They STILL haven't quite figured out how closing apps figures into it all.
So now they appear to be backsliding, and the market has responded - quite coldly.
But, as usual, the developers of the world, also feeling the loss of functionality, have already come through with their products - many of them free - to augment Windows.
The one thing that has me quite concerned is that there are parts of Windows now quite clearly being neglected. Backup is a good example. More and more warning and error messages are appearing in the event logs indicating Windows likes its own
backup facilities less and less. At some point it's going to just stop working. Bob seems to tout flexibility, but actually useful features being just
lost is benefiting only those who want to "drive the market" (to somewhere
else - presumably to power just toys), and not serious computer users. Where does that leave us? Looking for a completely different approach.

Multiple Monitor Issue

Alright, so I have a 15" Macbook Pro with the dual graphics cards (GeForce 9600M GT and GeForce 9400M GT 256 version). It's the 2.66 intel processor one. Anyway, I've been trying to figure out this dual monitor issue that I've been having for a few days now. When I'm using the 9400M card and I plug into my mini displayport everything works just fine. This includes the VGA cord, the HDMI, as well as a standard Apple monitor. Now, when I switch over to the higher end graphics card, as soon as I plug into the mini displayport my screen goes black. And that's it. I can't do anything. I have to hold the power button down until the computer turns off.
I've been searching for days in order to find an answer to this question or if anyone has ever had a similar problem and no one could help me. I even went to the genius bar and no one could help either. Keep in mind I've tried this in a variety of ways. I've plugged the monitor in after the computer was running, I've had it plugged in while the computer was turning on, and each time after the initial boot up everything goes black.
To make matters worse, I originally came across this issue because I use Windows 7 on bootcamp and I wanted to use dual monitors within Windows. Bootcamp is only set to use the 9600M graphics card which is the one giving me all the heartache and apparently there's no way around it. If anyone has the slightest clue as to what's going on here or why it would be doing such a thing, let me know. Thanks.

Jon: Thanks for answering those questions. Run the Apple Hardware Test that you'll find on one of the DVDs that came with your MBP. If any errors are reported, go back to the Genius Bar with the error codes reported by AHT and ask to have the machine repaired.
If you have extended AppleCare protection, you have a TechTool Deluxe CD/DVD. You can also use that to test your hardware. If it reports any errors, take the exact wording and error codes from that report along with you to the GB, too.
The problem is not with your three external displays or your cables, adapters, or your MBP's mini-Displayport, because they all work fine with the 9400M. The problem isn't some wrong contact that's being made momentarily as you insert the mini-Displayport plug into the port, because it occurs even when the cable is securely connected before starting up the computer. It seems to me the problem must reside either in your 9600M GT or in its connection to the mini-displayport.

Multiple Monitors issue

A coworker has a T400 laptop that worked perfectly with multiple monitors up until recently. Initially I thought the port went bad on the connector, but after veryifying it with the docking station, I am not able to get the connection to a secondary monitor. The second monitor will work with other computers and the docking station will also get a second display when another laptop is plugged in.
Can anybody suggest what would be creating this issue outside of a hardware failure?
Thank you.

Hi Waynedegan,
Thank you for the reply!
Check which version of Graphic driver is installed in your system?
Download the latest driver from the link & uninstall the current version installed. Install the downloaded driver.

Photoshop cs4 and multiple monitors

When i save a document as a jpg on one monitor and then drag the photoshop window to the other monitor and save it the same way, they turn out differently! Whats going on?

JohnVega
"On the Mac, the Application frame groups all the workspace elements in a single, integrated window that lets you treat the application as a single unit. When you move or resize the Application frame or any of its elements, all the elements within it respond to each other so none overlap. Panels dont disappear when you switch applications or when you accidentally click out of the application. If you work with two or more applications, you can position each application side by side on the screen or on multiple monitors. If you prefer the traditional, free-form user interface of the Mac, you can turn off the Application frame. In Adobe Illustrator®, for example, select Window > Application Frame to toggle it on or off." - Adobe Help "Using Photoshop CS4"
Once you have done that, move the whole block of the Application frame to the Display Tablet. You can then toggle between the monitor 1 and tablet monitor by switching on/off Application frame..

Multiple monitor issues with quicktime.

Hi, I can never get this issue sorted out with Quicktime. I run windows xp and use 2 screens. Whenever I open a quicktime movie it takes over one of my screens so I can't do anything on it except watch the quicktime movie. Is there a way I can run quick time so it runs only on the screen I have quicktime running and leave my other screen alone??
Thanks,
Syed.

Are your monitors set up correctly in the Display control panel settings for primary and secondary? I had a similar problem where a QT video would always open on the monitor to the left cannot remember how I resolved it, so thinking it might be the Display control panel. Or clearing recent in player prefs.

Windows XP and Wierd Java Issue

I apologize ahead of time if i am vague in some of my details, i can find more information if more is needed. I work on the helpdesk for a pretty large not-for-profit company and we have begun to see a bit of weirdness that seems to revolve around Java in some way.
Alittle Backgroud:
We have an in-house built application that runs heavy on Java, again, i can get more details when needed. It runs fabulously 99% of the time, it is just that recently we have see a growing trend on our Windows XP desktops. The program will be up and running, no issues, the user will then begin doing something else, it seems most of the time it is in IE 8 (web based) and then switch back to the Java application and find that the mouse no longer works within the application. You cannot click on anything, menus, close window x in the corner, nothing. Keyboard commands, alt+whatever, still work and tab allows you to navigate throughout the application fine. The only solution is to reboot the computer and then it works fine. PLUS, if we go into control panel and then open the Java Control Panel, that also doesn't respond to mouse clicks as well, but tab and enter works fine.
It has happened on multiple different computers in the company, same configuration, but never accessing the same thing or doing the same task, yet something seems to be breaking the java or something. We have tried to turn on the logging in Java Console, it shows nothing useful. We have checked event viewers, NOTHING at all.
We are unable to recreate it and it seems to happen at random times but always crashes mouse functionality in JAVA. It is really getting frustrating to the IT dept as well as the user base and i was just wondering if anyone has seen ANYTHING similar to this or have any suggestions to trying to track down the culprit process/program doing this.
Any Help would be appreciated.

Do a "echo %CLASSPATH%" at the DOS prompt...You should see the directory in which you installed Java...
Example:
CLASSPATH=c:\j2sdk1.4.1;.; where (".") = the current directory.
Your JVM cannot find the class file because you have not set the CLASSPATH enviroment variable. Your PATH enviroment variable sounds like it is ok because your OS(Windows, etc) is able to find the java, javac, jar, etc commmands.
Hope this helps.

BPC NW SP5 with Windows 7 and Office 2010 - issues with EvDRE reports

Hi All,
We are facing a BPC front end issue with the following symptoms:
1. Any report with multiple EvDREs crashes out either instantly or within a few minutes of operation.
2. Two EvDRE reports (or one report and one input tempate) crashes same as above.
The crash is either an EvDRE error message or an endless wait for the server to respond (where we have to eventually terminate the application).
We were suggested to move to sp7 but the issues persisted.
We do have a message and SAP is helping us investigate. What I want to understand from everyone is are there customres successfully using this combination (BPC NW SP5 Windows 7 and Office 2010) along with the above features?
Customer is really loosing confidence in the solution and is eager to find out if we are the only one using this.
Regards
Anupam

Hi Zach,
While I do understand we need to isolate the problem but testing on different combinations, customer at the moment is not inclined for this and is looking for other customer references that this environment is stable.

Windows 7 and blinking cursor issue...

(Just an FYI...I originally posted this in the MBP forum because I didn't realize there was a bootcamp forum)
I recently had my computer repaired through AppleCare. They replaced the logic board, top cover, a connector and battery. When I first got the computer back, I turned it on, booted to the Mac partition, everything was good. I then booted to Windows with the Bootcamp partition and everything was good. Even the stuff I had open before the damage were still up. I shut it down, boxed everything up and didn't touch it until I got home.
When I got home, I booted up Windows 7 and now all I get is it boots to a black screen with the cursor. I ran the repair utility, tried safe mode and it says no errors are found, however, it still won't load. I haven't figured out why it booted up the first time I got the computer back but now it won't do anything. I never got a chance to back everything up because my computer was damaged from liquid damage, but I can still see all the files on my Bootcamp partition through finder from the Mac side.
I don't know exactly why it's doing this or what to search to find an answer to the problem. When I first got my MBP, I installed Windows 7 through and upgrade disc from my job, so I don't know what my next steps should be.
Other steps:
Tried WinClone to copy the drive and it gave me an error message on the log.
Tried to run system repair several times and it came back with no errors. Same for memory diagnostic tool. Everytime I run the repairs, it finds no errors but still boots up to the black screen with cursor. Ugh, this is so frustrating.
Right now I have most of my files backed up on my external drive, but I still want to find a way to clone the drive and then it looks like my only choice is to do a clean install. How do I do that? Someone else set up the partition for me when I got my computer, so I don't know how to remove the version of Windows 7 to do a clean install or if I have to start messing with the partition. I only have an upgrade disk.
Any more thoughts? I thought about calling AppleCare but I doubt they'd help since it's Windows 7, but it was not doing this before the repair. I guess I'm lucky I still have access to the files.

Leeopard huh?
You need Snow Leopard w. 10.6.x to get 3.0.
If it works and no issues fine though probably the first time I have read someone did.
BC 2.2 was more about XP and some support for Vista.

Windows 8 and LR tethering issue with D7000

I just purchased a new Lenovo W20 laptop with Windows 8 pro, installed LR and PS6. All of this is up to date on patches.
I tried to tether my Nikon D7000 to a USB 2.0 and USB 3 port and have the same issue...
LR sees the D7000 and lists it in the tethering bar and sees the settings for aparture, ISO, and shutter speed. Problem is it will not import and show the files from the camera when I shoot, nor will it trigger the camera with the LR tethering button.
I have successfully shot with this camera when tetered to another laptop using windows 7 and the same LR current version.
Do I likely have a LR or Nikon driver issue, or is there some basic compatability issue with Winodws 8 that is yet to be worked out?
When I use explorer, i can see the files on the D7000 and the thumbnails show up fine in explorer.
Leroy

Are they using the built in reader in Windows 8 or is it opening in Adobe Reader?
I've noticed the built in reader app doesn't close files unless you close out of the application. So, you wouldn't be able to delete them until you close them.

Macbook Pro and Multiple Monitors

Hi,
I was considering on making the move to apple and getting the macbook pro.I multi-task a lot with my machine and was thinking of buying 2 20" apple cinema display's.Is their a way of connecting my macbook pro to the 2 cinema displays and to a 32" so 4 monitors including the unit itself can be run.It needs to be quiet cheap as well don't really want to spend a lot of money on it.All the screen's have to run different I don't want it to be mirroring on all four.
Thanks
Jonathan

No, not without buying an external video card unit that connects via the MBP's Express34 slot. It's not cheap, but one was featured on gizmodo a while back: http://www.tuaw.com/2008/03/08/vidock-gfx-brings-multiple-external-monitors-to-m acbook-pro/
There is no way to run multiple monitors off the single DVI port in the MBP.

RC and Multiple Monitors

2012 R2
So we are using Remote control but not useful on systems with multiple monitors, is there a way to make it work like "Offer Remote Assistance" does?
Thanks.

The options that fern pointed out above are on the RC client itself -- they are not client settings. They are under the "View" menu.
I've never had an explicit issue with seeing multiple monitors either; however, if you are, have you tried changing the screen resolution on the target system?
There's really no configuration to be had here, the best we can do is offer possible work-arounds.
If this is a major issue, you should contact Microsoft support or consider purchasing a third-party remote control tool. You can also file a change request on Connect so that it gets into their queue as a possible future change.
