NVIDIA Dual Monitor not working

I have two monitors, 1 QNIX 1440p running at 100hz that is properly working, the other, and 1080p Asus at 60hz is running at 1024x768.

Dual monitors not working in bootcamp?

Recently added 8 more gigs of ram, and after this my video driver shows a triangle with an ! under bootcamp running windows 7,
i have tried countless times to update the driver to no evail
even used the bootcamp drivers from the original discs to repair bootcamp and nothing has helped!!
what can i do?
before the memory upgrade the monitors worked fine under bootcamp, but now they only show 1 and will not show both!!
thanks!!
(possibly a windos 7 issues?)

Good grief, but please a) don't use Apple drivers, b) always use the "troubleshoot compatibility" for any installer (control+click on the application) before running. Apple is treated as not supported and won't install (now) with build 7077 (after feedback finding it causes errors, love the way their feedback and testing really does work).
Boot Camp can 'doorstop' in some cases a good installation.

Use Driver Sweeper and then reinstall the latest compatible driver. And no, dual monitors does work.
mine is the ati radeon 2600 hd xt and it worked flawlessly up until about 2-4 days ago,
oh well, xp pro it is then,
i dont want the headache of dealing with windows 7 beta!
xp should be fine to use correct?
will there be any other steps i will need to take in order for everything to function together well?
thanks

Wacom intros5 and dual monitors not working

I know there are issues with Mavericks, dual monitors & USB, but I have a problem with my Intuos5 tablet: since installing Mavericks it no longer maps to both monitors. Changing settings under monitors and wacom sys prefs does not change anything. It will only map to monitor 1.
in fact mapping under the wacom sys prefs doesn't seem to work at all.
Any ideas other than going back to ML or waiting for a new driver?
Anyone seen behaviour like this?
Thanks

Dual monitor not working under Boot Camp on Mac Pro ATI HD 2600 XT

Recently got a brand new Mac Pro with ATI Radeon HD 2600 XT graphics card.
On the Mac side (Leopard), everything works perfectly: my second monitor (a plasma screen connected with HDMI to the second DVI of the ATI card via HDMI/DVI adapter) is fully recognized and it works as an extended desktop or in Mirroring mode.
Under Boot Camp (Windows XP Pro) however, NOTHING: the second monitor always appears in the display properties, but it is grayed out (inactive), and when I try to activate it, it switches back to being grayed out immediately and nothing gets displayed on it.
After reading all the posts I can find on the topic, I tried the following (in pretty much every possible combination - Thank god for WinClone that allows me to restore the Boot Camp basic install image without having to reinstall Windows from scratch every time):
a) Bootcamp 2.0 (installed by default by Bootcamp assistant)
b) Update to Bootcamp 2.1
1) Windows XP Pro SP2c vanilla install (from my Windows XP pro install disk)
2) Update to Windows XP SP3 (I tried with and without BC 2.1: both worked -> BC 2.1 didn't seem to be required for SP3 - maybe because this is a mac pro and not a MB or MBP)
i) ATI drivers installed by default by Boot Camp assistant (BC 2.0) or by BC 2.1
ii) Latest ATI drivers found on ATI web site specifically under Boot Camp / Mac Pro.
Note: Interestingly, the catalyst installer worked ok (provided .NET framework 2.0 is installed though), but it seems that the Radeon BootCamp/Mac Pro driver set itself from ATI's web site does NOT include a driver for the HD 2600 XT - so when I install this driver set, it tells me that no compatible hardware was found...
iii) Latest ATI drivers found under Windows XP (these did include one driver specifically for the Radeon HD 2600 XT)
NOTHING seems to work. I read posts (most of the from late last year) about ATI Catalyst utility showing a 3rd monitor at some point, but I never got any 3rd monitor showing in any of my many many trials with Catalyst. I have yet to get a single image appear on my plasma under Bootcamp Windows. I don't believe its the hardware because everything works great on the max OS X side.
I am actually considering switching to an NVidia 8800 GT just to get the dual screen to work under BootCamp/Windows XP because I really need it and I read everywhere that drivers for NVidia are far better than ATI ones.
Any advice? What should I try next before getting an 8800 ?
Is there a diagnostic utility that I can use to test my config including the GC?
Thanks!

Hi there aside from my laptop I have an iMac 20" with the same HD 2600 XT card. I recently installed the Catalyst 8.6 driver by using a driver mod from driverheaven, I use Vista 32. By installing it this way I got boosted performance and many issues with the bootcamp drivers were fixed. As you may already know the ATI drivers do not install on bootcamped macs usually but the mod tool fixes this. Its unofficial so do so at your own risk but try it out and see if you get the second monitor if not just rollback. Hope this helps and I didn't want to say too much about the 8.6 driver mod because it may not be allowed here but google will provide any answers.

Dual monitor not working in 2012R2 essentials anywhere access

Hi
I tried to connect to 2012R2 Ess anywhere access (Remote portal) from a W7Pro client using two monitors.
Only one monitor gets used though. Can Anywhere Access be configured to enable dual monitor use in RDP sessions?
Many thanks
Rgds
Willem

Hi Willem,
As per my research, dual monitor is supported but for that to get access you need to have Windows 7 Enterprise or Ultimate version. Win 7 Pro client doesn’t support.
Apart this issue seems more related to Essential Forum, for detail you can ask in our Essential Forum over here for more accurate details.

Hope it helps!
Thanks.

Dynadock U3 - Dual monitors not working using Win 7

So in October i upgraded to Windows 8 when it came out and it didnt work properly with my Dynadock docking station.
So i downgraded to Windows 7 using a copy i got through my school that didnt have the proper drivers for Satellite laptops.
So last week i finally got a recovery disk from Toshiba for my laptop and reinstalled windows 7 with all the proper drivers for the laptop.
After doing this i reinstalled the Toshiba Dynadock Drivers and tried to set it up with my laptop.
The mouse and keyboard attached to the Dynadock station work properly with the laptop but the external monitor doesnt work at all.
What can i do to get the external monitor working?
Btw my BIOS is up to date as is everything else so everything should work properly. it doesnt make any sense....

Yes it did
it worked perfectly fine when i originally ran it on windows 7 so i think its a software issue
but i bought the recovery disk to get my PC back to its state of when i bought it which should be like it was when i originally had it as Windows 7 but it still doesnt work
also the keyboard and mouse attached to the docking station are a bit glitchy, sometimes it will print out a lot of a letter when i press it once. I hate this and its really getting me annoyed with Toshiba because according to the the technical support i phoned, if i bought the recovery disk, it would get the docking station working properly....
so now i dished out $38 for a recovery disk for nothing :/

[solved] xorg 1.6 - dual-monitor not working any more

I switched to arch64 and with it came the new xorg 1.6. Now X won't start with the configuaration I used before and I can't figure out what to do about it.
I want to use two monitors (laptop + external) with an Intel X4500 HD und xf86-video-intel. I found out, that it doesn't like the virtual screen I defined. If I remove that line everything works fine for the laptop-monitor. With the virtual screen defined I get an error in xorg.0.log

I use "xrandr --output VGA --mode 1280x1024 --left-of LVDS" in .xinitrc to arange the displays.
So anyone any idea why it won't work?
Btw: I tried x86-video-intel-legacy. But then X didn't even start

Ok, I fixed it. Just added
Option "AccelMethod" "UXA"
Option "Legacy3D" "False"
to my device-section in xorg.conf. EXA produces the error above.
Maybe I'm looking at the wrong point, but could someone give me a hint where I can learn more about UXA/EXA. The problem seems somehow solved, but I'd like to learn more about this and would like to understand what the problem was. Right now I don't even know what makes the difference between UXA and EXA It just works.
And somehow google doesn't make it a lot clearer for me right now...

Dual Monitor not working for Mac Pro (Early 2008)

Upon upgrading from Lion to Mountain Lion yesterday I lost the ability to use my secondary monitor. Checking in System Preferences it indicates that it only sees one monitor, but nothing has changed with my hardware configuration. Is anyone else having this problem?
Hardware specs:
Processor 2 x 2.8 GHz Quad-Core Intel Xeon
Memory 26 GB 800 MHz DDR2 FB-DIMM
Graphics ATI Radeon X1900 XT 15 MB
Software OS X 10.8 (12A269)

Not sure if this has any relation to yours, but I thought I would throw it out there...
After installing Mountain Lion, the secondary monitor for my 27" iMac would not wake up after the computer slept. In the System Preferences, there was only the main display listed. The secondary monitor was visible from a cold boot, but disappeared once the computer slept and was woken up.
I found that waking the system with the Magic Trackpad would not also wake the second monitor. When I wake the computer by using the keyboard, the second monitor wakes normally! I've repeated this several times... Strange.

Mountain Lion 1.8.2 update made my dual monitor stop working on Mac Pro mid 2012

Just done Apple's update for Mac OS X Mountain Lion to 1.8.2 and after rebooting my dual monitor stopped working.
If I go on preferences -> Displays it shows me only one of my two monitors, even if I invert the connections the 2nd monitor doesn't shows up and there seems no way to enable it again.
Any suggestion?
P.S. I already tried to set from "Best for display" to "Scaled", but after rebooting Mountain Lion 1.8.2 reset it to "Best for display"

Ok,
did some extra test here, but first of all my configuration:
Mac Pro (Mid 2012) with ATI Radeon HD 5870 1GB.
2 LCD 24" Wide-screen (1st monitor Hyundai W240D and 2nd Monitor HP w2448hc), both LCD worked perfectly until reboot after installing OS X 1.8.2
After reboot only the 1st monitor wored fine, the 2nd not even listed, so tried to invert cable connections on the 2 miniports on the ATI video card, but nothing changed, still only the 1st monitor working.
Did a second test, disconnected the 1st monitor and connected ONLY the 2nd and now the second works fine.
Tried to connect 2nd monitor on a different miniport, and i still works fine.
Updated my MacBook Pro to 1.8.2 (it as an nVidia card) and connected my 2nd monitor to it and everything works fine, both the laptop LCD and my HP LCD are working fine.
So it looks like Apple screwed up the ATI driver on the latest 1.8.2, now only ONE miniport is active.
To all users with the same Mac Pro configuration: hold to update to Mountain Lion 1.8.2 until Apple fix this driver issue.
More info are on the Console output, so will have to contact Apple on-line support to signal this bug.

Seeking a clear description of getting dual monitors to work

I've spent a long while researching the issue of getting dual monitors to work on a new mac mini - which I will be purchasing as soon as I figure this one out! But I am bamboozled by references to the various types of connections and ports. If anyone has the patience to explain this really simply and clearly, I'd be very grateful.
Interestingly, the Apple guy on the phone today told me it isn't possible - it's either/or for the display connections. But clearly it IS possible, because there is so much discussion about it here...
Here's where I confess my technical limitations, and say that I am confused about what I need (to purchase, presumably) to get my two existing monitors to work with the new mini.
They are presently connected to my PC (soon to be ceremonially consigned... etc) with cables which have regular D-sub connectors at each end. This means they are vga, right? There is no digital connector on either monitor.
So I am trying to figure out
a) is it possible to use these two monitors in a dual display setup with a mac mini? If so:
b) How?! And then;
c) what leads and/or connectors do I need to buy in order to connect them up?
Thanks for being here, I hope for some patient guidance.
Jeff

Welcome to the Apple Discussions!
An '09 Mac mini has two video out pots on the rear; a mini-DVI port and a mini-DisplayPort. The Mac mini comes with a mini-DVI to DVI-D adapter. If you use what came in the box with the mini, you need a DVI-D to VGA cable to connect one of your monitors. Otherwise you need a mini-DVI to VGA adapter and a VGA to VGA cable for one monitor. For the other monitor you need a mini-DisplayPort to VGA adapter and a VGA to VGA cable.

DVI to Video Adapter with NVIDIA 8800 GT not working

Hi all. I have the new Mac Pro Octo (mar '08) with the NVIDIA GFORCE 8800 GT card. I cannot find anywhere what may be wrong. Only on the Apple Website for the adapter that the only Mac Pro it works with is the Mac Pro (with ATI X1900 XT). However, both tech support and Apple's Store staff said this would work, prior to buying it. Well, my computer does not recognize the TV monitor hooked up via S-Video. I've powered everything down, restarted, unplugged and replugged in both orders, and switched inputs on the TV and receiver both. Nothing.
Any one know if this does or does not work with this computer???
Thanks.

Never mind. Found this out via Apples own website. Thanks APPLE TECH SUPPORT and STORE STAFF for getting me to buy a useless cable!

Video Monitor Ports
The Mac Pro has a DVI connector for an external video monitor. For a description of the DVI connector, refer to Figure 4 and Table 30.
The graphics data sent to the digital monitor use transition minimized differential signaling (TMDS). TMDS uses an encoding algorithm to convert bytes of graphics data into characters that are transition-minimized to reduce electromagnetic interference (EMI) with copper cables and DC balanced for transmission over fiber optic cables. The TMDS algorithm also provides robust clock recovery for greater skew tolerance with longer cables or low-cost short cables.
Note: The Mac Pro computer includes a DVI to VGA Adapter.
DVI to Video Adapter
The Radeon HD 2600 XT graphics card supports an optional DVI to S-video/composite adapter that provides S-video and composite output to a PAL or NTSC video monitor or VCR. When a display is connected by way of the video adapter, the computer detects the type of adapter and enables the composite and S-video outputs. The settings for the resolutions and standards (NTSC or PAL) are then selectable in the Display pane in System Preferences.
Note: The DVI to Video Adapter does not come packaged with the Mac Pro computer and must be purchased separately.
The video output connector is a 7-pin S-video connector. Figure 5 shows the arrangement of the pins and Table 31 shows the pin assignments on the composite out and S-video connector.
The Mac Pro computer provides video output at picture sizes and frame rates compatible with the NTSC and PAL standards; the picture sizes are listed in Table 32. Those picture sizes produce under-scanned displays on standard monitors.

NX6200TC-TD128ELF - Multiple Monitors not working

I recently picked up a NX6200TC-TD128ELF PCI Express. It is installed in the PC in my Sig. I have been using multiple monitors on nvidia graphics cards for several years now. I buy nvidia because they just work so well with dual monitors. Anyway, my latest upgrade isn't working out so well. I've tried the MSI drivers from their website, and the newest Forceware directly from Nvidia (81.98). Windows just doesn't see a second monitor attached to the DVI port. I use a DVI -> D-SUB adapter (I've tried 2 just in case the adapter was bad).
Does the NX6200TC work for dual monitors? I can't find much info about it on the web, short of an MSI press release about the NX6200TC-TD32E where they state "The card is also capable of running dual analog monitors, or an LCD and a CRT." I would assume my card should be the same, just with more memory on it. Any ideas out there, or should I RMA this thing before it's too late to do so? I've had to put in a junk PCI card I had lying around so as to get my dual monitor fix.

Hi,
We've been using a similar card - the NX6200TC-TD128E (without the LF, the full height version) in dual monitor mode OK, but we use the TV out as the second monitor (TV + D-Sub). My initial evaluation was done on the non-TC version, but that shouldn't make a difference.
I found that Clone mode (and extended desktop modes) is only available if the card thinks there are two devices attached. So it looks like the DVI connected monitor isn't being recognised.
Have you tried swapping the monitors over on the two ports and seeing if the recognition stays with the port or follows the monitor?
My earlier testing (with the non-TC version) found that the card would recognise a monitor on the D-Sub port if it saw a resistance of less than about 150 ohms between the Green output (pin 2) and 0V (pins 6-8 amongst others). Normally a monitor should present a DC impedance of 75 ohms on its R,G & B inputs - but if the monitor has AC coupled inputs it would fail the test. I didn't try the DVI port but it probably behaves in a similar manner. {I just tried it, and it does work - although this is on a Jaton PX6600, but it should still be valid}
You could try putting a shorting link (i.e. a short piece of suitably sized wire) between pins 2 and 7 on the DVI-DSub adapter, plugging in said adapter, then going to the nVidia setup. If it "recognises" the piece of wire, the first menu setting should now be nView Display Settings, not just Display Settings. [If you look at the D-Sub end of the adapter, with the wider part at the top, pin 2 is second from the right on the top row. Link it to any of the three right hand pins on the middle row. Or you could make a proper dummy load by soldering 75 ohm resistors between pins 1-6, 2-7 and 3-8 of a 15-pin plug]
An alternative method is to turn on "Force TV detection" in the Tools menu. Annoyingly, it will probably force you to reboot. Or you could connect a TV to the TV out port (before going to the nVidia setup).
Another annoying thing I have found is that some of the menu options seem to appear or not appear at whim - for instance the ability to set up a hot key to toggle Clone mode. It makes it very difficult to write instructions for others if the software doesn't behave consistently.
Anyway, I hope this helps.
Cheers

Nvidia Quadro 4000 not working properly

Hi all,
I am really hoping that some one can help me with a very frustrating issue with my new Mac Pro and Nvidia Quadro 4000 card.
I purchased my Mac Pro from an Apple store and added the Quadro 4000, I need that card as it is supported by Adobe Premiere CS5 to enable the GPU acceleration. The reason I went to the store to buy instead of online was to get advice about the card as I have not used a Mac for 5 years now. I was told that they are not familiar with the card, but put it in and run alongside the ATI card.
When it arrived I put it all together, except for the Quadro 4000, and it all worked perfectly. I have 2 x 27” Cinema Displays attached. I installed production studio CS5 and then extremely carefully added the Quadro card.
Without going on about all the drama with it not working with the ATI card and then removing that and installing only the Quadro, it is not doing what I bought it to do. Adobe is not recognising the device, I have updated to version 5.0.3 of Premiere Pro, which supports this card.
I think I know what the problem is, but I have no idea how to resolve it. I put the Quadro in and then installed the drivers. My research says this is wrong (there were no instructions in the box and the read me file on the disc just said I need a specific cuda driver), so I removed it, put the ATI in and hunted down all the Cuda (Quadro stuff) files, deleted them, reinstalled drivers and reinstalled the card. No change, it drives one display and Premiere still cant see it.
I have tried to find answers on the internet, Apple are not very helpful as it was a third party item they have no training on (although purchased from Apple).
The only thing I have read is it may need to be on OS 10.6.5, I updated to 10.6.6 and/or because I installed the card before drivers. I have read that I need to sort out ‘Permissions’ but can’t find out how.
Any help would be greatly appreciated, I really need to get this thing working as I have a very expensive computer I can not use.
Thanks
Phil
Oh, one other thing, it is supposed to run two displays, one via display port and the other via DVI, but I am having no joy here either, and there seems to be no DVI male to MDP female adapter????

You are making it (sounds like to me) harder than it is.
You do not mention which ATI card, but you should use both side by side unless you have the 5870 which is using the two pci 6-pin power connectors on it.
With Mac OS people generally never need to delete drivers by hand.
ATI 57x0 and Quadro work better together. Or even ATI 4870 and GTX 285 in the past. Use the ATI for monitors and Quadro for CUDA and Mercury.
FYI for Quadro 4000 Mac Owners upgrading to 10.6.6:
Included in today's 10.6.6 related apple docs is one noting new Quadro 4000 owners need to Reinstall the Nvidia Quadro driver update after updating to 10.6.6.
To save you a lot of clicks (the doc links to the nvidia product page) - here's the page with the current (as of this AM) Quadro OS X 10.6.5 Driver page which still shows the 11/16/2010 driver date/v256.01.00f03. But the file I downloaded this morning is named "Retail_256.01.00f03v5.dmg" (28.9MB) - dated Dec 17th. The file I downloaded back in mid-Nov does not have the "V5" in the filename and is larger (37.3MB). I don't own this card and not dug into the pkg to see what changed (i.e. did they remove the extra kexts for other models perhaps?) but just a FYI.

Reinstall the 10.6.6 combo update manually is sometimes a good idea (some of us use only combo updates when it comes time to update OS X).

DVI out to external monitor not working anymore

Hi,
I have been using my MBP with an external Dell 17" LCD for a dual monitor setup. Suddenly after about 5 months of flawless working, it is not detecting the external display anymore. The display is not at fault - another powerbook detects is as ususal. I tested my MBP with another cinema display and again, it is not detecting it at all. I have tried F7 toggles and "detect display" from system preferences. No use at all.
Any ideas?
Should I just take it to the local applestore?
Thanks.

I don't know if SMC resetting fixed it or that RAM resetting fixed that issue...but now the MBP recognizes the external display all the time.
However, it has another issue now -

NVIDIA: Dual monitor question (geforce FX5200)

Hi all:
I've been using my geforce FX5200 nvidia card single monitor, just a CRT plugged into the VGA port. I had two CRTs and used a VGA->DVI adapter to attempt to get the second monitor to show (the card has a DVI and a VGA). I was never able to get the second screen to work that way, I don't know if the adapter was bad or the wrong one, but nonetheless it didn't work. I finally got a "DVI monitor." What's the easiest way to get this second monitor to work?

They should both be picked up on the nvidia-settings tool?
In theory yes, but in practice there was a problem (or possibly a "feature") on some nvidia cards (or maybe a limitation in the driver) which I also experienced on FX5500 where you couldn't use certain pipes in combination. For example using VGA+TV-Out was not possible so you would have to get a vga-to-dvi adapter and use DVI+TV-Out, which was possible. Since your first try with two CRT monitors failed it might be that your can't use VGA+DVI in combination.
Edit: unfortunately it was so long ago that I don't have any resources on this. But a quick search now brought me to another example of this
