10.4.5 doesn't see my second monitor

I just upgraded to 10.4.3 and then immediately after that to 10.4.5. Since I did, my computer can't see my second monitor. I ran the system profiler and it sees the second video card.
This is not a problem in 9.2.2 and it wasn't a problem in 10.1.5. Can anyone help me out? Thanks!!

It sounds like the firmware or drivers of the graphics card is out of date for 10.4 to understand there is a display connected to it or to give that option. Contact the graphics card vendor to see if there is more info you can get on either. Tell them the issue you are facing. Also check http://www.apple.com/swupdates/ if it was an Apple supplied graphics card as a build-to-order or part of the original release of that Mac model.
http://www.xlr8yourmac.com/ has a good database of graphics cards you can choose from and their compatibility.

How do I get my Mac Pro to see the second monitor through a video splitter and/or switcher?

In a recording studio we have a Mac Pro with two video display monitors in the control room and we want to be able to show the content of the second monitor to the person in the recording room on a big display monitor there. However, when we interpose a switcher or splitter between the computer and the second monitor so that we can (with a switcher) switch the second monitor signal from the control room monitor to the record room monitor or (with a splitter) split the signal to go to both monitors, we have no luck. On startup the computer does not see the monitor through the switcher, so it doesn't recognize its existence. If we start the computer up without the switcher in the signal chain, it sees the second monitor just fine, and (weirdly enough) we can then change the cabling to interpose the switch, which then works to switch back and forth between second monitors (control room and record room), but that cable swapping's a royal PITA. We want a simple solution that will allow us to start up the computer, see the second monitor in the control room, then choose to show it to the person in the record room with a simple flip of the switch (or even better, split the signal so it's available both places). The splitter we've tried most recently is this one: http://tinyurl.com/curen39 I'd appreciate any advice from people who have tried this configuration or something similar with success. We have a full ProTools HD Accel 3 system installed, so there's no room to install a second video card. Thanks.

Thanks for the response! Yes, it's a 5x70 video card, a 5770 I believe. In any case, it does have the three ports, but (a not-well documented fact) that doesn't mean one can really get three full-resolution signals out of it at one time, as you alluded to in your message. So, yes, we did try hooking all three up directly to the computer, but the computer would only recognize two of those monitors, and the only way to get it to "de-recognize" the second monitor and recognize the third monitor was to physically disconnect the second monitor.
I did say when you want to connect three monitors to 5x70's there are some rules to adhere to. These are covered in the first two apple docs mentioned above, or by title:
Mac Pro (Mid 2010), Mac Pro (Early 2009): Issues with three displays and multiple DVI, HDMI connections
Mac Pro (Early 2009), Mac Pro (Mid 2010): Supported display configurations
The general gist of these rules is that to drive three monitor son a 5x70 you need two active adapters. That is why one of your monitors was disabled when you tried to add a third.
Here's a good explanation of what's going in here and why you need two active adapters on these cards:
Active vs. Passive Displayport adapters *the truth*
If you use DVI monitors and any of them have resolutions less than 1920 x 1200 then you can use single link active adapters. The "AMD Eyefinity Validated Dongles" chart shows some active (and passive) adapters that are acceptable. For example of a single link DVI active adapter is the Accell B087B-006B. An example of a dual link DVI active adapter would be the one from monoprice.com if you need to connect monitors with a resolution greater than 1920 x 1200.
I'm doubtful that SwitchResX would be able to convince the computer that there were only two monitors connected and direct the second monitor signal to the correct place, but it certainly seems worth a try, so thanks for the idea! Any other ideas are still welcome in the meantime.
I'm not doubtful. It is a very powerful utility for dealing with all aspects of multiple monitor configurations (they call them "Display Sets") complete with forcing EDID information if necessary. The different configurations can be controlled with a (contextual) menu and/or hot key.
SwitchResX is academic at this point if you want to have all three monitors connected. You would need to get that working first. Then use SwitchResX to vary the configuration combinations. So if you go this route the "name of the game" is figure out the active adapters you need.
I only described in general terms above about the adapters since you never said exactly what kind of connections these monitors require (single link DVI, dual link DVI, hdmi, mini-displayport, vga).

Mac mini doesn't recognize the second monitor

I have Mac mini mid 2011 with dual display setup - one HDMI, the Second one thunderbolt to DVI adapter.
Majority of times it doesn't recognize the second monitor connected through thunderbolt. Sometimes it start suddenly after a while, I've read there are some issues with the 10.10.2 Yosemite...
Any suggestions how to sort it out please? Many thanks, this is really a pain in the *** for me, strugling for a half an hour with a monitor...

Thanks lllaass I tried it but doesn't work. I tried with different cables, still doesn't work.
The strange thing is that sometimes it suddenly starts and works smoothly... Really strange problem. I will try a new adapter Thunderbolt to HDMI....
What is the worst, when both monitors work smoothly and I put the computer to sleep or i shut it down, when started all over the monitor is not recognized.
Ehhh :-(

Duplicate mouse cursor appears (but doesn't move) on second monitor

I have a Mac Pro with the ATI XT1900 video card and 2 Dell 2407WFP LCD monitors attached via DVI.
When I'm using an application, such as a web browser, and the cursor changes state (like the black arrow with spinning wheel in corner) a duplicate of this cursor state appears on my second monitor, on the left-hand side of the screen.
This cursor DOES NOT MOVE, but does animate, and will not disappear unless I move my "live" cursor over to the second monitor, which I imagine causes OS X to "refresh" the position of the cursor. It realizes the duplicate shouldn't be there and it vanishes. The second cursor seems to appear only when the primary live cursor changes state, as in the black arrow becoming a black arrow with spinning wheel in the corner, etc.
This is not a duplicate cursor due to having Displays set up to mirror one another. The second cursor doesn't move.
This has happened in more than one software application, so it appears to be some sort of display driver error at the system level.
Anyone else experience this or have a way to fix it? There have been several Apple Updates to OS X since this problem first started happening (on day 1 with the Mac Pro) and it has not been resolved.

Time Machine doesn't see my second internal drive; want to back it up too

I have a Mac Pro with two internal hard drives. I didn't have anything on the second drive before, but now since my first drive is getting full I transferred about 170GB onto my 500MB drive. I can't figure out how to back up this drive onto my Time Machine drive and have spent 45 minutes looking through topics.
I checked in Disk Utility and the 2nd drive is Mac OS Extended (Journaled). I go into System Preferences Time Machine and it only asks which drives to Exclude, not Include. There doesn't seem to be a way to add another drive. Can anybody help me?
Thanks!

Time Machine should be backing up all connected drives unless you tell it otherwise. Did you take a look through your backups?
Try a +Backup Now+ and see if the drive gets backed up.
Is the TM drive or this drive formatted as "case-sensitive"?

New dual mac pro using fcp studio doesn't see external crt monitor

I recently invested in a system to re-edit film and set up my system...dual editing up is fine I put my larger dell monitor through the 3870 which is in bay one and the browser comes up on the 2nd monitor connected to the 2600 in bay 2.
The problem is I can't get my EXTERNAL VIDEO out go to the crt monitor...this is connected by svideo that's on the 3870 which my primary monitor is connected to. Under "video playback" there's no option to choose "apple firewire" the only thing on that menu is the "digital cinema desktop preview" and only those choices, the same under my audio/video settings under the "final cut pro" menu. Theres no option I see on here either for mirroring under the playback menu either am I looking in the wrong place?
This appears to be a software issue as I'm not seeing the other options under video playback to even recognize the dv connection to my primary monitor...I've seen commentary in other logs to try deleting preferences but which ones?
The crt monitor is seen under my apple hardware, I can move things in and out of it...only in final cut pro I can't get external monitor on it...and when I choose this cinema choice the picture comes up on my main monitor but only as a still it doesn't seem to allow me to choose "all frames" in any case.
My main concern right now is to get this external monitor to be read by final cut PLEASE HELP thanks!

Got the "apple firewire ntsc" choice to show up even if grayed out and "missing" under "audio/visual" menus by recreating choices in Easy Setup under "final cut pro" MENU thank GOODNESS because I was reading horror stories on here about this under another thread with someone trashing preferences, reinstalling and the works and still not getting it to show up...on my search now for an analog/digital converter up at b&h...find it odd that the s video connector wouldn't show the crt monitor when I put both displays through the 3870...I switched it back to see if it worked again when only the one dell monitor display was there and there it is again mirroring the screen display on my desktop...just can't be seen as an "external monitor" in fcp...couldn't find anything specific in the shane ross threads to this. I'm sad the program doesn't just see the s video connection though the 3870 though my computer does fine and will query up at b&h in regard to what might be affordable as far as a digital/analog converter. It's also weird in itself that when I put the two dell monitors on the one card my computer no longer could see the s video crt connection...makes no sense. Will report in later as to what I discover up at b&h as I'm sure there's a world of people out there using this sony crt monitor still even into the upgrades with computers and software so I imagine therein lies the solution. Thanks again and I'll report in as to what hardware might be suggested for me.

T400 Vista 64bit cant see second monitor in port replicator

I installed Vista Business 64bit on my machine that came with 32bit Vista. I was able to download all the drivers. Everything works except it will not see my second dislpay on the port replicator. It sees the VGA display but not the DVI one.
Although the ATI software installed , I cannot use the control center. It says Ati catalyst control center cannot be started becuase the current active GPU is not supported.
Tried calling support and they wont help me becuase the machine came with 32.
If I go in through thw windows display setup it doesn't see the second monitor. This all worked with it was 32 bit vista.
Anyone know of any way around this without going back to Vista 32?

My Mac Pro Desk Top computer no longer can "see" my second display??

I've tried reversing the connections on the back of the MacPro but it still doesn't "see" the second display. I've had these two displays hooked up for years with no problems. I recently upgraded to Mountain Lion and I just had the MacPro in the Apple Store for a "One To One" transfer of data to my new MacBook Pro laptop. When I brought it back home it still worked fine. I then was cleaning up some stuff and I know I went into my "Users and Groups" panel in System Preferences and I did remove some items from the "Login Items" list that open automatically so maybe that is the problem?? I know the second display is getting power and recognizes it's connection to the compuiter because when I disconnect it, it says, "no signal" and when I reconnect it, it just goes to sleep. Advice appreciated.

Some of the graphics cards that had two DVI connectors had one Dual-Link (suitable for all resolutions including wider than 1920 wide) and one Single-Link (suitable for resolutions up to 1920, but not wider). This does not appear to be your problem, since both are less than 1920 wide.
The "Drivers" business is a complete Red Herring (Not Applicable), as the Mac does not use Drivers for displays -- it uses a unified driver for the Display CARD, and customizes it based on the capabilities reported by the Display when connected. In order to get this to work, the display must correctly self-identify.
To verify that the display is correctly detected, look in:
About This Mac > ( More Info ) > Graphics and Displays ...
... a correctly self-identified display shows its Name and its maximum resolution. be skeptical, this information does not update when you plug/unplug the display, and you have to close and re-open this window (or possibly the entire program) to get the information to refresh after a change.
If either display provides a USB cord, it must be plugged in to complete the display connection and provide display ID and control (this is much more common with Apple displays that third-party displays).
Is there any evidence of trauma to the display connectors or cables? Any bent pins on the connectors?

Second monitor stopped working with MSI Cyclone OC 460GTX 1Gb

Hi everyone!
I recently bought this card and it worked well for about a month. I woke up one morning to see my second monitor having turned black. There appears to be a signal of some sort since I don't get the "no signal/input" message, but there's no response no matter what I try. I went back to the shop and they confirmed the same error which was then believed to be a broken secondary DVI port. They tested a new card and found it to be working, but I got the same black screen when I came home and plugged it in.
I'm using a 24'' BenQ G2400WD and a Samsung SyncMaster 173T. As they worked well together for about a month and did so on my old 9800GT as well I have no reason to expect the actual monitors to be the cause. They both work fine on DVI 1, but none of them do on DVI 2.
I'm currently sitting with my second card and have tried the following things:
- clean install of new drivers
- uninstalling the last windows updates before the second DVI port stopped working (and then doing a clean install of drivers)
- confirmed that both monitors work on the other port
I've talked to the shop again and they told me they got the card I handed in to work by making sure it was properly connected. I've made sure of this myself as well of course, but without any luck. The guys at this place are known for being good at what they do so I have no reason to suspect that they overlooked anything obvious. The fact that they've gotten both cards to work at their place puzzles me a bit.
My current theory is either a bad batch of cards or some sort of windows update breaking dual screen support. I would expect to have heard about it if it was a windows issue, but both cases might be underreported given that most people only use one monitor. I filled in relevant information in my signature to the best of my knowledge. Please let me know if I've missed something and I'll try to figure it out.
Any help appreciated

OK, I will let you know. First update:
Vendor has already given me a RMA number(less than 2 hours). The VGA card should hopefully be in the snail mail process tomorrow.
One weird thing, my RMA was degraded from replace to repair. Not quite sure about that one? Not sure if that means that it will be replaced or sent to MSI from vendor for repair/or vendor will attempt repair? Only time will tell, I guess. The only great thing is that just one of these 4890 Cyclone OC cards beats out a single 3870x2 vga card hands down. And thanks to this forum, I was taking some time to read up on this forum. I must say I am impressed, keep up the good work moderators and MSI. Thanks and will keep you updated. Special thanks to Svet.

Second monitor only shows when I open PPRO a second time.

CS5 WIN7 - 64 Pro
Looking for a suggestion /solution to an issue I have had for some while.
I have the latest Nvidia Drivers for QuadroFX3800 but the issue began at least two previous versions ago.
I open PPRO and it does not see the second monitor. It is not an option in the Playback settings. (Not even there / Not greyed out)
In fact it shows an image briefly (flashes on then off) on the second monitor then turns it off (ie. the image going to it from the source monitor.)
I shut out of PPRO and re open it almost immediately. Bingo. 2nd monitor shows and its is also an option in the PB menu.

I think I'm right in sayng that Mosaic has been added to the latest driver, 267.05 - the ability to stretch the desktop across 2 monitors. I haven't been aware of it before.
I say that because, having toyed with Mosiac, I noticed that PP CS5 did flicker a few times upon boot in a way that it didn't on earlier nVidia releases.
It seems to have settled down now.
Am I not right in thinking, shoternz, that you are using the 2nd monitor as your preview, rather than program monitor? Maybe there's a corrolation.
Get your BM Intensity Pro out of the cupboard!

Cannot Connect a second monitor to HP 500-314PC

I have a new Pavillion 500-314. It has a VGA and DVI-D connector at rear. The comuter will not see my second monitor. I have it conneced with a dedicated line DVI-D to DVI-D. When I switch the monitors , the VGA works on both. One monitor is old and so it is connected to VGA port. The other monitor has both DVI-D and VGA, but I cannot get the DVI-D to work.
Any thought? Thanks

Itunes messed up my restore and now doesn't see my ipod. What should I do?

I performed a restore on my Ipod Touch (bought new a couple of years back) and itunes tells me there was an error and the restore could not be completed. Nice that it still manage to delete all my information, contacts and goodness knows what else (I chose to backup my files using the itunes function), btw.
Anyways, now my ipod just has the "connect to itunes" picture. My PC doesn't recognise my ipod, apart from Apple Mobile Device under USB controllers in the Device Manager, and itunes doesn't see or try to do anything with my pod so that I can use it.
I've tried this solution http://support.apple.com/kb/TS1538 but that didn't help and I reinstalled itunes and Apple Mobile Device Support, but to no avail.
What should I do? I'm using Windows 7 HP x64.

Put it in DFU mode.
It's a common thing among jailbreakers. No one else really needs it, but it should allow your iPod to take the official firmware of your choice.
Here is a copy from a jailbreak help guide I will not link.
Please note that this will not jailbreak your device, so back off, moderators.
Method (1)
* Attach the phone to the pc
* Turn the phone off
* Hold power and home together for *exactly* 10 seconds
* Release power but keep holding home until the pc beeps as a USB device is recognized.
* At no point will the display come on. Now your restore should work.

BAPI_ISUACCOUNT_CHANGE doesn't see what BAPI_ISUPARTNER_CHANGE changed

Hi,
I have a program where I am adding payment cards and bank accounts to a business partner and then creating them as incoming payment method of a contract account. Therefore, I call the BAPI functions like:
CALL FUNCTION 'BAPI_ISUPARTNER_CHANGE'...
CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'.
CALL FUNCTION 'BAPI_ISUACCOUNT_CHANGE'...
My problem is that the last BAPI doesn't see the result of the first BAPI call. That is, if I use the first BAPI to create a payment card or bank account for a BP, and then try to insert their ID's as CA's incoming payment method, the second BAPI returns error message saying that I am using non-existant data. If I run the same program with the same data for the second time, everything works fine.
How can I make the second BAPI immediatelly be aware of the changes made by the first one?
Thanks!
KR,
Igor

Igor:
add parameter wait = X to your commit call. If that still does not work, then maybe add an explicit wait step between the two change processes.
regards,
bill.
