  • I installed seven last night on a 2year old viao laptop. I discovered after the install that both my monitors were showing the same thing and went into diplay settings. just to discover that the system did not detect the second monitor?  Tried rebooting with the monitor unpluged and reconnecting after but same problem. Is this a unsupported issue or do I need to get something from Sony after a clean install? 

    If it IS supported, it will be supported by Sony, or whomever makes the video card.

    Are you talking about Multiple Monitors?

    Win7 makes using multiple monitors easy.

    I attached a second monitor after installing Win7.

    Went to Personalize/Display/Change Display Settings.

    You will see both monitors displayed, select monitor number 2 and select Extend these displays in the Multiple Displays drop down menu.

    If you do not see the second monitor displayed, clcik the Detect Button.

    Hope this helps.

  • Thanks for the reply. 

    That is not what im talking about unfortinatly. What i am talking about is having all one resolution instead of having two monitors with two resolutions. It is called span mode, not extending.

  • I'm looking for the same thing.
    I've got 3x 1600x1200 monitors, and I want to have the option to maximize an application to 4800x1200.

  • Hi

    1. This is video driver feature, but not windows feature. If your video and video driver support such a mode you will have option to set it via windows options

    2. My nvidia driver have option to set mode you want, called duplicate these displays mode.

    When i set nvidia driver in duplicate displays mode for monitor is displayed 1|2(multiple monitors)

  • The ATi Catalyst Drivers allow me to maximize Firefox to a (completely useless) 4800x1200, true.
    However, I want 3D applications to do that very same thing (a panoramic World of Warcraft would be an interesting novelty, but I'm really referring to using Microsoft Flight Simulator in 4800x1200 spanning resolution, in Virtual Cockpit mode, with a head-tracker like TrackIR, where "novelty" is replaced by *fully immersive*.

    I cannot find a way to get a 3D App to launch at any resolution higher (or wider) than the native resolution of one single monitor. Under XP, it was a snap - Select "Span Mode" in the drivers, and the WDDM allowed the drivers to "merge" the monitors into one monitor that was the size of all three combined (i.e. 4800x1200, or 1600x3600 for vertically stacked monitors, etc.)

  •  nView Horizontal and Vertical Span Modes
    Due to architectural changes in the new Windows Vista Window Display Driver
    Model (WDDM), span mode cannot be supported in NVIDIA graphics drivers.
    NVIDIA recommends using the built‐in Windows Vista multi‐display modes.


    This was not a driver issue in Vista... It's a Vista Issue. Just do a Google search for Span mode and Vista.

    Now the big question will Span mode work in Windows 7? as I as a Microsoft certified partner am thinking of Dumping Vista Ultimate off my gameing computer in favor of Xp just so I can span my 22" widescreen monitors..

    This effects more than just gaming, AutoCAD and any other application that used the Span mode because of it's massive display capability are all crippled in Vista.

    My display mode in XP would have been span mode 3360 x 1050 but Vista is 2 independant displays of 1680 x 1050
    the span mode is supported in both hadware of Nvidia and ATI graphic cards & it's possible provided your GPU and Handle the math in 3D

    So can we Span in Windows 7 or are we Gamers, autocad users and anyone else that uses span mode be religated to XP?

  • And how you expect your video card(s) to process screen with such resolution?

    Even it is possible have to 4800x1200 or 3360 x 1050 for 3D, you will not see even slideshow, because one frame will take minutes



    Friday, February 13, 2009 3:29 AM
  • ROLF You have seen my specs.. In X3 Reunion and similar games am pulling over 120 frames a sec. on one monitor, I can actually run the game twice @ the same time once on each monitor and still make 40+ frames a sec on each for a total of 80 frames a sec..... so no it looks really good..

    You definitiely are not a gamer... since movies are less than 40 frames a sec i don't see this as an issue. & regualr TV is closer to 25
    Have another excuse?

    There are Thousands of us with systems capable of doing this... other wise intell and amd would go bankrupt and so would nvivia and ATI  We push the envelope.

    I know you don't, not my your answer you probably don't even have a gpu in your computer, let alone one with more than 10 times the cores of your cpu.
    Friday, February 13, 2009 5:05 AM
  • Ventislav -

    At 1600x1200, I'm currently pulling 60-90 FPS in Lord of the Rings Online, with *every* detail in a gorgeous game turned to High with an ATi 4850X2 with crossfire mode OFF. When I turn Crossfire mode on, I jump up to the 150 FPS range, which is in the land of "downright silly" when my LCD is only 60 hz/FPS...

    Surely I could keep playable (30+) FPS at 4800x1200, with some level of reduced detail, don't you think?

    ...Nevermind that I have an ASUS motherboard with room to put in another identical card... *twists handlebar moustache*

    However, if 7 continues the braindead WDDM model of Vista, then I'll be looking for a copy of XP64 that I'll keep until they pry it from my cold, dead hands.
    Friday, February 13, 2009 6:49 AM
  • I agree with you completly Jonathan,

    Any game is completly playable @ 40 fps & the 60Hz of the LCD monitors makes that easy on the gpu's
    Unlike my old 21" crt's that typically ran at 120Hz ...

    I also agree with you on the XP if windos 7 continues on the path of no span mode there will be a lot of people keeping their Xp boxes, we just have to.
    Also AutoCad and other high end apps need the span mode for 2 or more monitors it makes working on large 3D project modles much much easier.

    Actually Jonathan's card would handle the load by itself for both monitors.  and the the 4800x1200 or 3360 x 1050 is using both dvi ports, so the gpu's don't have a problem handleing this. since this card will do 5120x1600 in span mode. for 2 monitors or 7680X1600 for 3 monitors

    Also, I "accidentally" enabled (yes, it was for sure a feature because it allowed customization with right click) dual taskbars on my separate displays....

    Have any idea how to do that?  I just can't find the manual way to enable and disable this awesome feature that we have all been waiting for!

  • Disappointing to see that no Microsoft official can answer or at least have the slightest idea of what we are talking about. Windows XP had span mode in the nvidia drivers working perfectly and under Vista they say it's impossible to do. This is a reason why some people don't want to upgrade to new OS. Microsoft introduced this problem in Vista and should plan to fix it in the next product release, or else they simply fail.

    I actually need to reboot under XP every time I want to play a splitscreen cooperative game to have both monitors working, then get back on Vista for work and stuff, it takes some time.

I thought this would be a very simple to answer question either yes or no. I am fully aware of why Vista does not support this. So Ventsislav Alexandriyski, could you please stop telling us that it is a driver issue because it is not. Clearly everyone here knows that it was an architectural change. 

    Therefore I would really apreaciate an MVP that knows what they are talking about to help me out on this subject. I would really like to upgrade to Windows 7 seeing as it is suppose to improve on Vista which as far as performance goes, the beta results are all saying it even out performs xp.... =P we'll see.

    Hi Eibach

    Sorry you feel that way, this just isn't a feature that we see requested very often. It seems to be a favorite of Gamers and those people are always teaching us new things.  :)

    The bottom line is that it doesn't do a lot of good just discussing this with other users here. You need to follow Mark's advice and let the Windows 7 Devs know what you want.

    Regards,

     
    Thank You for testing Windows 7 Beta

    Sorry, but this is driver issue!!!

    When Vista was released video cards had problems with tv out and the reason is the same as now - stupid video card driver programmers.

    Video cards manufacturers lie consumers, that this is windows problem, because they cannot tell to people that was paid for 4 video cards, that they cannot make good driver.

    Of course users are much more stupid than driver programmers and this is why they want SLI or Crossfire.

    Ideo of SLI and crossfire is the same stupid idea used by voodoo cards, but with better PR. SLI and crossfire are obstacle for technical progress and failt is on stupid users that use them

    If video card manufacturers was and monitor manufacturers, then multi-display problem would not exist, but now video card manufacturers does not earn money from monitor sells, so there is multi-monitor problem

    Is this clear enough for you?!

    Thursday, April 09, 2009 3:44 PM
  • No. Apart from calling everyone stupid, I don't see any argumented sense in your post. You don't even seem to understand what are we talking about.
    Thursday, April 09, 2009 4:27 PM
  • This is NOT a driver issue..., we want true multi-monitor support!

    Multiple taskbars
    Span AND Extedended for at LEAST 3 monitors as a basic option!

    These are driven by the OS, and the 3rd party programs like UltraMon don't even work with Win7.  I have a video card that is being completely inhibited by the OS structure, not driver incompatibility.

    Unfortunately Mr. Alexandriyski, you don't even address what most of the common multi-monitor users are talking about.... "Is this clear enough for you?"

  • Firstly, the moderators are working to a set of guidelines; however it is generally accepted that the user who opened the thread will be asked before the question is finally marked as answered by setting it to a proposed answer (unless they fail to respond).

    Secondly, you asked "Will windows 7 have span mode..." and the answer was given that it is a driver support issue - not an operating system function.  As far as I can tell, that is true.  It is also an answer, just not the one that you would like to hear I guess.

    So, the answer is either:

    "no"

    or

    "it depends on your driver"

    depending on whether you believe this is a driver issue or not!

  • As far I can tell, however, nVidia at least made an official statement about it. From that point on it is just people giving their opinion who is to "blame". Though the fact remains that a "soft-enforced" spanned resolution, something available 10 years ago, remains just a myth in 2009.

    Seeing how two monitors behave in Vista (secondary is black until logging in, no taskbar on the other and similar basic functions that you have to buy a special 50€ hi-tech application for), I somehow believe nVidia. =)
    Sunday, April 19, 2009 9:09 PM
  • Today is 2009-05-13. Windows 7 RC1 does not let me set nVidia 8800 GTS in span mode. Windows XP on the same machine does. Microsoft Flight Simulator X is unable to render more than one screen in Windows 7 Ultimate RC 1.

    The Span mode runs 1680+1280=2960 pixels wide on my XP with 25-30 fps. Not all settings are maxed out.

    The driver for Windows 7 was downloaded today from nVidia. It is version 2.5.373.05. 

    In nVidia Control Panel application the page "Set up multiple displays" is missing the span option that is present on Windows XP.

    FSX is the sole reason for running Windows for me. Unfortunately it is also locking me down to XP.

    If it IS supported, it will be supported by Sony, or whomever makes the video card.

    I do not need to understand what you think, and I doubt you understand what you want

    Why is this man still allowed to write in here? To keep with his offensive attitude against the rest of us? Please, go away.

  • You cannot vote again or vote on your own post.There is no answer here. And my download of windows 7 does not have horizontal span.
    Looks like I am using XP till Windows 8.
    I run 2 Gateway Extreme HD 1600's off a 640MB Nvidia 8800 GTS and have 9 virtual desktops.
    You cannot fit all my same time apps on a single task bar it's saturday and I have 28 apps running right now and I am not even working.
    One you go horizontal span you don't go back.

    Advantages of Horizontal Spanning:
    1. switch to any active app with a single click
    2. using a virtual desktop like rvd allows easy access to all aps
    3. any app that needs attention lights on the taskbar
    4. single image accross the desktop background
    5. application window larger than a single screen

    Any disadvantages?

    P.S. edited this in Windows 7 IE and the formatting I got is above

  • So far almost noone attempting an answer to this question even understands what XP horizontal-span or XP vertical-span mode is. To break it down for those answering things outside the OPs question, XP span modes are a driver level mode that allows for a single video card GPU with 2 outputs to push a single 3D canvas that can be used as a single virtual display over 2 physical displays. It is set inside the nVidia control panel in the multiple displays window. With the change between XP and Vista neither Microsoft nor nVidia put the option to use this mode anymore. Countless people have asked who to contact to get this implemented again but Microsoft passes the buck to nVidia and nVidia passes the buck to Microsoft on this. Noone will own up to even who is required to be contacted to get this option back in place again. A simple google search of the search terms vista, span modes will turn up a large amount of displaced users that lost this feature although almost everyone posting to this thread don't even know what the mode is. What people posting here and missing the answer are not understanding is that this is a mode for spanning 3D full screen across 2 displays transparently without any special hardware tricks like a Matrox DH2G Digital.

    Microsoft and nVidia really need to look into this matter because there is a quantifiable set of users that were displaced and disappointed with the removal of this feature set in the transition from XP to Vista and now still missing in Window 7. It's disappointing that an advanced feature like span modes works perfectly in XP but in Vista and Windows 7 it's removed. This is 2 steps backwards as far as feature set progress and a great disappointment to many.

  • well i just loaded windows 7

    no horizontal span!  so 2x19" monitors not seen as 1 screen   WTF

    so no eveonline with 2 screens  ,that game really needs it

    so i'll be telling the 40000 concurrent playes of eve that dont go windows 7.

    i suspect the WOW players are doing the same,

    Windows XP king of operating systems yet again.

    was going to BUY windows 7 i'll save me money and get a triplehead to go instead and stick with XP.

    i wanted more monitor support NOT less

    annoyed ,disgruntled and removing windows 7

    horizontal span NO going back

  • Hi,
    today I installed ubuntu for my development machine and I noticed that the TwinView (virtualized resolution aka spanning) is still available in the official nVidia driver package, although I am having some problems with it (linux newb).
    My point being that nVidia did not forget or discard this feature from their driver bundles.
    What I know about the issue for sure so far is that the WDDM changed. Now, did the MS devs really "screw" things up so bad, or is nVidia being sloppy, not willing to invest time/energy into fixing the matter for us to be able to run the Spanning feature on the new driver model (which is probably better than the old one)?

    Heterogeneous Graphics and More

    Windows 7 and DirectX 11 will usher in a few more minor tweaks to the graphics landscape, though they're not the highly impactful things discussed on the previous pages.

    First, there's heterogeneous multi-adaptor support. In Windows XP, you could have two different graphics adaptors with two different driver stacks running, provided they each were connected to their own monitor. You could even extend the desktop this way.

    This feature was missing from Vista, but with Win7 and WDDM 1.1 drivers the capability will return. Note that this doesn't let you use two different-brand adaptors together in something like SLI or Crossfire to render one display faster—it's strictly a multi-monitor solution.

    I think this has more to do with how the drivers work and nothing to do with actual span modes. I see nowhere in the article where it states span modes are in again. Now if it does add in span modes again, great -- but that article does not read to me like it has anything to do with span modes.

  • Well, me too.

    Just for a bit of background - I own a software company and have an MSDN subscription and about 35 years programming experience.

    I just installed Windows 7. Looks nice. I want to use it to get to know it so I can support clients and test my software on it.

    However, without span mode it is just unusable for me. I have 2 1600 by 1200 monitors and I need span mode for too many things.

    So its back to XP for me.

  • I'm saddened that feature appears to be missing from Win7 as I enjoyed it a lot for WoW in XP.  Without it I'm definately going back to XP.

    That is essentially just a cop-out answer by Microsoft. They design the Windows Display Driver Model and choose not to support span modes in it. That answer is as though they have no choice, which of course they do have a choice in how they design WDDM to work. Microsoft is deliberately choosing not to support span modes in WDDM because they don't want to budget to put it back into their new driver design. That's unfortunate and a very lazy business decision on their part.

  • I, too am another user who is sorely disappointed by the lack of horizontal span in Vista and now, Windows 7. I'll describe another critical use of horizontal span (for me) that no one has mentioned so far. I use two of the legendary IBM T221 DG5 displays, which have 3840 x 2400 resolution (each). No current monitor has yet to exceed this resolution, so for desktop space there is no parallel (an exception is the 4k/8k projectors, but if you have $100,000 lying around you're in a different league).

    Problem with these 3840 x 2400 monitors is, they require TWO dual link DVI connectors each to push that many pixels (even Displayport doesn't have a single connector bandwidth to do this). So in effect, each T221 becomes two 1920 x 2400 stripes side by side. In Vista (and I assume Windows 7) these two stripes act as totally different monitors even though they are in the same LCD panel!! Total deal breaker. With XP, horizontal span combines the two stripes and I have a 9 megapixel single monitor as it should be. XP even allows me to have two of these 9 Megapixel monitors over two video cards with four heads.

    Again, count me as another person who will be buying 4 less Windows 7 licences. Microsoft has disappointed me time and again by omitting this feature, though I am sure Nvidia shares some of the blame too.

  • Has anyone heard from the nVidia folks?  I would think that through single or multiple GPUs and multiple monitors they could emulate a single "spanned" monitor to Vista or 7.  ATI has done a similar thing using ATI Radeon Eyefinity.

    http://www.matrox.com/graphics/surroundgaming/en/home/

    It's called TripleHead2Go... I'm going to buy it in a couple of weeks and try it out. Matrox guarantees it will work on Windows 7.

  • Hi Joseph,

    After having read through this forum I have to say I'm pretty damn disgusted at the MS attitude to this issue.

     I am currently developing SOE's for our organisation (Government), we use horizontal spanning.

    I Disovered this issue this morning when attempting to use this configuration in support of a user. MS need to solve this problem otherwise people like me are simply going to say to the heads of Depts. here forget Windows 7 its unsuitable for our use.

    We'll be recommending XP for this feature.

    This is very remiss of MS to leave such an important feature out.

    The fact that its an architectural problem is no excuse.

    This is simply not good enough!

    Its NOT just the gaming community that make use of horizontal spanning, and from my organisations perspective alone this question should remain open until MS come out with a workable solution.

    Last time I checked, we are the customers asking/expecting a product we pay for to live up to the expectations and precendents already set by manufacturers, not the other way around!

    I really dont think MS is taking this issue seriously enough!

    Cheers,

    Dave

  • Hi Dave

    This issue has always been driven by technological advances in the Graphics industry.

    The operating system just provides the extensibility that supports advances in the graphics technology.

    Both of the major graphics hardware makers have solved this problem with newer hardware drivers that provide span mode in Windows 7.

    ATI Calls it EyeFinity, which is available in most of their latest cards and I believe nVidia calls it SLI or 3D Vision configuration which is available in most cards that use their graphic chips.

     

    ATI Eyefinity Technology

    Information and Answer from nVidia 

    Hope this helps.

    Thank You for using Windows 7

  • Why is SPANNING MODE NOT in Windows 7???

    We've been using XP with multi monitor and multi video cards with SPANNING MODE ACTIVE!

    WHY REMOVING THIS FEATURE??? We've built customer sulutions using these mode, why in the ... removing something that was there??? 

    Anyway, we're just killing the Windows 7 projet, so many copies that will NOT but purchased!

    Unless we get some explanations... and no, this is not a video card driver problems... WDDM was modified to remove this... WHY??  Anyway, I DONT CARE about the why... we're CUSTOMERS and care about what we used to have... and an UPGRADE is not LESS but MORE, not in the case of WINDOWS 7 for sure.  This is BUSINESS users talking here, not just GAMING boys!!

    By my tone,... yes... we're not happy. 

    good luck

  • No it really doesn't help.  Not trying to be rude, just factual.  Your NVidia link does not answer the question of how to enable spanning on Windows 7.  It's merely an explanation of which cards support dual monitors.  I have one already, and don't really need a new one.  It's a GeForce 8800 GS card.  I've had it for a couple of years.  Sure, there are newer cards, but it works the way I want it to under XP, and it doesn't under 7.  This is what I like to call negative value.  Unless Microsoft's objectives have changed to sell less of their product and not more I would think they might want to fix this issue.  Even for "gaming boys" who happen to need an OS every now and again. 

    I really don't care.  Don't fix it.  I won't upgrade.  But pretending like it's not an issue doesn't make the problem go away, and it's not going to help you sell more copies of Windoze.  Oh, by the way, some of us gaming boys actually work in positions where decisions are made regarding software purchasing.  I might suggest our whole company just skips Windows 7 (we're not there yet and really don't need to be).  Better yet, maybe we'll see if we can get by with Linux and avoid the MS tax altogether.  We're already considering it for other reasons, but they mostly tie back to arogant vendors who want to force feed their customers what they don't want.

    As a gamer I am totally downed that I can't play across all my screens.  As an Imaging Informatics engineer I am appalled.  Recently, I designed some high end systems for our Radiologists.  Win 7 is completely useless to us since the diagnostic imaging controllers for our 3 and 5 megapixel screens will not work due to the changes from XPDM to WDDM. We had to put old XP 64 on these $9000 medical workstations to be able to use them at all.  Bad move M$.  Even xp-mode would not work to solve the issue.  Please fix this.  What happened to backwards compatibility??  Wasn't win 7 supposed to be better at it than Vista, doesn't look like it. 

    Thank goodness I didn’t invest more money in high res IPS panels that require Dual-Link DVI.  Would have just wasted my money as they appear to not work with win7’s new graphics architecture either.

  • Upgrade to the Windows 8 abomination. It adds back horizontal span (besides ruining everything else) due to Metro.
    Tuesday, May 22, 2012 11:49 AM
  • Ronnie, this is quite untrue. Horizontal span (NOT EXTENDED DESKTOP) is the responsibility of the OS, because it determines how it places the DX surfaces onto the display. NOT vice versa, the driver has no concept of how the application should be displaying a DX surface - this is a call that the application makes to the MS DX library not the driver.

    So, the "patches" that NVidia and ATi released are not really good solutions for people who need applications to behave consistently across OS's. We have spent a huge amount of time trying to combat these issues ourselves in the simulation industry and Win7 has been a large road block in the deployment of multi display multi-resolution spanning. We often have simulations that are built in singular DX surface technologies (like Unity3D with DX9 - Unity4.. has at least fixed this) where we have multiple camera views that we span across displays to show different outputs of the simulation. Sometimes they need to be multi channel forward vision coupled with an output for an "on device display". With current Win7 system it is extremely difficult to solve this problem without doing a large amount of extra development (either integration with NV / ATi solutions or developing distributed synchronised displays).

    Sadly you have lead people astray with EyeFinity and Mosaic. Mosaic especially is only for Quadro level cards, and not available to general consumer cards. Additionally it is NOT performance friendly. Neither is EyeFinity for that matter. These technologies are not suited well for generic use, because of where they lie in the display pipeline.

    After reading a number of threads on this topic, I am a little surprised that people make all sorts of claims about the necessity for spanning, and its operation and solution. I think people who never use or or dont 'need' it should just not comment. If your experience and understanding is limited, then why cloud issues with guesses? (not referring to you Ronnie, but there have been some others who have been plainly trolling).

    For people in the sim business, and large/multi display business I would recommend a few solutions in order of "best fit".

    1. Use hardware if you can, because software / driver solutions are invariant and bug ridden. We found this chinese company making some amazing hardware:
    http://www.dhgate.com/mvd206-six-screen-dual-link-dvi-multi-display/p-ff808081278edf3401279f2e15bb7b62.html#prod-body-related
    This is an amazing 6 channel display splitter. Works very well (although we only needed 4 !! :) )
    2. Use Matrox triple head2go or dual head2go. Again, easy solution that works for all application types.

    3. Try a software package called SoftTH - its a little hit and miss, but works surprisingly well. We will be keeping an eye on this project because it may be the best 'generic' non hardware solution for the use of spanned / multi-res display setup.

    4. EyeFinity and Mosiac (if you can afford 3K USD video cards).

    5. Win8.. re-introduced span mode. Although there are problems with older software (3D wise especially).

    There are other software packages like UltraMon and a bunch of others, but they seemed extremely hit-and-miss. Sometimes they worked well, other times not. SoftTH is recommended purely because it worked on so many machines, and setups - this is rare for this sort of display control system.

    Hope this helps those who have been hampered but this Win7 issue. We have been stuck on WinXP for so long, and when we made the move we ran into so many display issues due to not having this facility (which should be in the OS) it surprised me it was removed.

    Cheers,

    Dave Lannan
