2 VGA displays, one blueish

Hi,
I just got a Mac Pro 2.66 GHz to replace my old G5.
Now I've got two identical VGA-LCD-Displays (Dell E171FPb) connected to the GeForce 7300GT. Unfortunately, one looks very blueish. I tried to calibrate the blueish display, but I couldn't even get the brightness high enough to see the "Oval between two Rectangles".
The problem cannot be in the displays because when I swith them, the blueish color will affect the other display.
Anyone else had a similar problem and how did you solve it ?
Or any idea ?
I had a slightly color difference on the G5, so I has to do something with either the card or the adapters I'm using (bot from Apple)...
Thanks a lot !

Hmmm.... I cannot swap the adapters because they have different layouts.
One has pins in the middle and the other one hasn't.
But it could be a correct answer... I might have taken one of the adapters from my previous G5, and this machine had the blueish-Problem too (but to a lesser degree; I previously used two Sun-Monitors on this machine and they had a similar problem... -> Might really be the adapter...)
Due to the fact, that the problem occured to my old Mac too, I can't think of a graphic card problem.
I was thinking, that it could be a driver or a misunderstanding of the DVI or the two different DVI-out concept...
But are my basics right ? I can have two displays connected to the two differend kinds of DVI ports on the same card ?

  • Snow Leopard killed my vga displays!!

    This is by far the most weird problem I have ever encountered after upgrading to a new OS.
    I run a company where we have something like 15 different Macs. Mostly Intel, but different ages, Mac Pro, Macbook Pro, iMacs, Mac Mini etc.
    A couple of days ago I wanted to upgrade one of the Mac Pros to Snow Leopard. It's an early 2008 3.1 with ATI hd 2600 graphics. I wanted to do a clean install, but instead of backing up everything from the system drive, I pulled it out and put in a new clean one. This way I could retrieve the data from the old drive when I need it through a USB docking station or something.
    Installation went by fast and without any problems what so ever.
    But first thing I noticed when the first bootup was completed was that the resolution of my monitors were suddenly completely wrong. I have two Samsung Syncmaster 2343nw monitors connected through vga, and they have always been detected and automatically been set to the correct resolution in the display preferences dialog by the old Leopard. I have around 9 of these monitors working as dual displays on Leopard machines, and a few working as extra external monitors for a couple of Macbook Pros running both Snow Leopard and Leopard. They are all connected via an dvi to vga converter and they always get detected correctly as "Syncmaster" in Display preferences.
    But suddenly now, they just show up as "VGA Monitor" in Display preferences.
    After fighting with this for a couple of hours trying all the suggested workarounds I could find, zapping PRAM deleting /Library/Preferences/com.apple.windowserver.plist changing the cables and so on, I finaly gave up. Fortunately I didn't overwrite the old Leopard installation so of cause I could just swap the drives back and everything should be dandy after booting back into the old Leopard install.
    But **** no! Now the resolution was equally messed up in Leopard! And none of the two monitors were detected as "Syncmaster" in display pref. Now they only show up as "VGA Monitor" as they did in Snow. ***?? How can an OS mess with a monitors plug 'n' play capabilities?
    I then tried the obvious which was to try and reset the monitors, remove power from them, Zap the PRAM again. I even tried a different graphics card (that didn't work in this machine) but what ever I did, the monitors where no longer detectable by the OS.
    Next step was to take some identical monitors from a different machine. And yes, they where detected by Leopard on the problem machine. Since I couldn't believe that Snow had actually ruined the other two monitors I booted back into Snow hooping that it would now detect these other identical monitors. But no, same problem. Back to Leopard, and once again now suddenly these couldn't be detected by Leopard either.
    I have since tried these monitors on all the other Macs I have in the company, and only one machine with an nVidia card is able to detect them correctly as Syncmaster. But none the less also this machine isn't able to see the monitors native resolution thus making it impossible to select the right setting for the monitor.
    So now I have 4 monitors that's virtually unusable after being in contact
    I have read a lot about people who who suddenly can't use their secondary monitor after upgrading to Snow Leopard and that Apple is aware of this, and that 10.6.4 should address this problem when we finally get some new graphic drivers. But I haven't heard about anybody who's monitor lost it's plug 'n' play capabilities after being in contact with Snow Leopard.
    But maybe someone here has had any similar experience? Maybe somebody else has had luck with upgrading a dual vga monitor system to Snow Leopard? I would love to get some ideas on what happened since these monitors doesn't really work anymore on any computer.
    Thanks!

    Hmm... I know that the screens native refresh rate is at 60 Hz and the resolution is 2048 x 1152. I'm unable to check it out now but I'm pretty sure I can't select 60Hz. They only have VGA connectors (the same as D-Sub I guess?) And the closest I can get to the right resolution is 1920x 1280 (or maybe it's 1200, not sure) which looks almost right, but then again not, and a whole lot more fuzzy than it used to be.
    On some machines the displays are detected as "Display" and on others "VGA monitor" or "VGA display". It's supposed to detect as "Syncmaster". Nothing changes if I press "Detect". I've only tried on machines running 10.5.8, and one brand new iMac running 10.6.3 through a display port to vga converter.
    But thanks for link to the toms article. I'll give it a read

  • Mini DisplayPort to DVI + DVI to VGA Display Adapter, will it work?

    Hi,
    I have a MBP, and I have just purchased an apple Mini DisplayPort to DVI adapter.
    I want to connect it to a VGA port.
    Can I buy an Apple DVI to VGA Display Adapter and connect it to the connector above.
    Will that work? Any one with experience who could advise me on that?
    Thanks.

    This does not work, because the Mini DisplayPort to DVI adapter has a DVI-D port that transmits only digital signals. VGA uses analog signals.

  • HT3382 I have an early 2006 Mac Mini and need to connect it to a VGA display.  What connector should I use?

    I have an early 2006 intel core solo Mac Mini (locted in India) and need to connect it to a VGA display.  I have looked at the support articles but can't figure out what adapter to use.

    There was a DVI to VGA adapter included with the early 2006 mini.  The one that I have looks like this
    You should be able to buy one, although it's not currently listed in the US Apple online store.

  • HP Slate 500 and HP HDMI to VGA Display Adapter (NP031AA)

    The specifications page for the HP HDMI to VGA Display Adapter (NP031AA) (Link) doesn't list the HP Slate 500 as a compatible device in the campatible products list (Link).
    Do these two products work together?
    What VGA resolutions can I project using this cominbation of products?  Am I limited to 1024x600? or 1024x768? or does it support displaying higher resolutions?
    I'm thinking about making a purchase but I don't want to get the adapater if it isn't going to work.
    Thanks,

    Yes an HDMI to VGA adapter will work fine. Keep in mind it will not carry audio but neither did your old vga connection so I am assuming it is not a problem. 
    You would find an HDMI to VGA at any Best Buy or you can order on one amazon.com such as here:
    http://www.amazon.com/BestDealUSA-Adapter-Converte​r-Laptop-NoteBook/dp/B007PLL4CK/ref=sr_1_2?ie=UTF8​...
    Connect the projector and use the Windows key at the lower left of the keyboard and the p key at the same time and it brings up a "projector" console that lets you easily switch from laptop to projector to laptop + projector.

  • Second Monitor seen as "VGA Display"

    Has anyone seen this before? I have a Mac Pro 1,1 with 2 nvidia 7300 GTs, and three Acer x193w displays connected using VGA to DVI adapters. Only one of the monitors is recognized as a "x193w" with the second and third seen as "VGA Displays". The primary monitor has the appropriate resolution listed (1440x900) but the second and third do not. All resolutions listed for the second and third displays cause them to be askew (a round circle appears oblong). I have tried booting OS X 10.5 with the same results. This is a new machine to me as well as being new to MAC so please forgive me if this has been discussed on this forum somewhere as I could not find it.

    Yes, adapters are the same, cables are the same, and monitors are the same. We have tried switching adapters and cables with no change. It appears that of the two video cards only one of the four heads sees the monitors for what they are. It does not matter which of the three monitors is connected to that port.

  • 17" Studio Display & VGA Display

    I was recently running dual 17" monitors on a dual 800 G4. When I powered down, I disconnected one of the 17" displays. When I turned the system back on, the cpu still thought one of the monitors was connected. When I clicked on display preferences, I noticed (1) 17" studio display (not 2) and a VGA display.
    It appears that the G4 thinks there are two monitors and I cannot find a way to tell it otherwise. Can anyone help?
    Thanks,
    Sean Dahlberg

    Personally, I'd spend the money on a new display with a DVI or VGA connection already. While I'll be the first to admit that I become attached to my Apple products, there must be a point at which you spend your money on something new rather than a $300 band aid.

  • Macbook dual VGA display output

    Hi, I was wondering if there is a way to use 2 VGA displays in extended desktop mode with my Macbook. I currently use my MacBook (with lid open) with a 21" external display, but just found an old 18" monitor which I would also like to use. I am willing to use these 2 displays with my MacBook lid closed.
    Is it possible to use this setup with a VGA splitter cable perhaps, or do I need to buy a USB to VGA cable/adapter (and if so, can you recommend one)?
    Thanks!
    Adam

    In that case, is there any USB to VGA adapter for mac that you can recommend? I believe they have their own display cards in them.
    Thanks

  • MBP shows VGA display, but none connected

    I am facing a quite strange problem. My MBP shows an external VGA display but there is none connected. I can see it in the display preferences. I already checked the hardware but there is nothing wrong with it. I connected a real display via dvi to vga and it works fine. Anyone who knows this problem and knows what to do about it?

    Found a possible solution.
    Do you have bootcamp installed?
    I restarted into windows xp and checked my nvidia settings and made it was set to "Use One Monitor"
    Then restarted and Voila!
    Hope it can help

  • VGA display powered off

    iMac in classroom, with VGA display connected for occaisional use.  When I open a new finder window it opens on this 'second display' which is not on, and thus invisible to me.  I want the window to appear on the iMac desktop, but it uses the external display.  So my options are power on the display,  wait for it to come on, then turn around behind me and drag the window back to the imac desktop, or to physically unplug the display. 
    Is there a way to gather all app windows onto the imac desktop in one fell swoop?  Seems a simple UI task, but I can't discover it.

    I would use the Apple mini-DVI to DVI adapter and then get a DVIU to HDMI cable from a local retailer. They are also available online from a ton of places - and probably at a lot lower price.
    There really is no need to involve VGA when you would need another adapter to go from VGA to DVI, then the cable to go from DVI to HDMI. I would take that adapter to your local Apple Store and see if they would do an exchange for you.

  • Two Dynadocks on Mac - two VGA displays simultaneously?

    I own two Dynadocks: PA3542EY1PRP and PA3541EY1PRP.
    They are connected to iMac 21 "Snow Leopard".
    All USB ports work but I can not run two VGA displays simultaneously.
    If one works, the other does not work.
    Drivers Display Links are updated.
    Surely there is a conflict.
    Any help is appreciated.
    Thanks a lot.

    Thanks for your answer. I also wrote to Display Link forum. Here is their reply (It's not the answer I was hoping for...):
    +Hi+
    +I think these were the first dynadocks Toshiba released. When manufacturing them, they managed to program them all with the same serial number - all zeros. This means multiple devices cannot be distinguished on the USB bus, so our software can only communicate with one dock at a time.+
    +Unfortunately this is a limitation and means only one of this first generation dynadock can be used at a time. Toshiba fixed this in their later dynadocks that are sold now.+
    +And no - there is no way for a user to reprogram the serial number. It has to be done in the factory.+

  • Non-existant vga display

    Hello. In my arrangement tab of display settings it shows my main monitor with a smaller VGA display off to one side. I don't have a second display and my desktop icons keep going over there so I have to get them with the finder.

    I just upgraded to Leopard 10.5 then 10.5.1... its still there.

  • MBP (early 08) shows VGA display when nothing plugged in

    My macbook pro early 2008 shows VGA display when there is nothing plugged in. It performs just like there is an actual display plugged into it. I have run AHT and it tells me nothing is wrong. I have reset pram. I deleted all the prefs that relate to the video prefs. It actually works when i do plug a DVI-> VGA Adaptor, but when i plug the DVI-> Video adaptor in only the s-video works. Composite video ends up with out any luminance. My best idea is there is a pin jammed in there from one of the video adaptors, and it's somehow telling the system that there is an adaptor plugged in, but I'm open to trying anything right now. This computer was purchased 3 years and 1 month ago, so it's just out of apple care.

    well it is a hardware issue, at least it has nothing to do with OSX. I did recently delete my bootcamp partition, and I know the windows version of the nvidea driver has a bit more control over things, I'm wondering if I should reinstall bootcamp to see if it is something in the Video Card's rom that Windows changed. I read that somewhere in a post on this board somewhere someone was able to easily change this problem in that driver.... why do you think AHT wouldn't catch the issue?

  • IMac screen suddenly recognizes VGA display that isn't there? Big problems

    Hello:
    My dad was using his iMac G5 when the display went to a blue screen (detected an external display) and formatted to take up a small amount (10-12 inches) of the 17" screen. As I was writing this, the detect display blue screen again flashed and returned to normal.
    Under display prefs, it listed a VGA display. However, there isn't even an adapter in the adapter port. Does anyone know what is going on here? I live several hundred miles away and it just so happens that I was here for the weekend. I would like to resolve this asap.
    No AppleCare.
    Thanks,
    Tyler

    Sorry to chime in without a solution, only another query along the same lines. I have a co-worker who's imac (24" 2.33 intel) sometimes starts up thinking that there's a second smaller display connected. The first time this happened, the dock didn't show up (she had it set along the right-hand side, it was apparently on the "other" screen), she restarted and it would then show up. A couple of days ago I was doing some updates, restarted, and the dock disappeared again. I noticed that the mouse fully disappeared off the right side. Having seen this behavior when two displays were connected in the past, I went to the display preferences panel and it registered two screens, the main one and a much smaller one on the right side. I clicked the "detect displays" button, which reset it correctly back to a single monitor, thinking issue solved. But this morning the same issue occurred. Easy to fix, granted, but I was hoping there might be a more permanent solution? I don't think there's a single displays preferences file that might be replaced, and I'd just as soon not mess around with pitching the full system preferences file unless that'd be the only solution...
    Thanksmuch in advance, and have a good one!

  • Computer falsely shows VGA display connected (reported by several)

    --- From this thread (http://forums.macosxhints.com/showthread.php?t=68002) over at macosxhints ---
    My 24" iMac (2006, the last white one) Core2Duo all of a sudden has started showing a "VGA Display" attached, which of course is impossible. From reading this thread it sounds like it's a motherboard issue? I rebooted into Win7 beta on my Boot Camp, and the imaginary screen also shows up there as an "analog display" which I can't remove.
    I'm long since out of warranty, never bought AppleCare. Fortunately, so far the iMac is still usable, I'm not having the blue screen issues described earlier. I can go into Display Preferences and set the VGA Display to several different resolutions...I set it to 640x480. Clicking "Detect Displays" doesn't do anything. And I can change the Arrangement of the screens, and enable and disable Mirroring.
    Very weird problem...thanks for any further comments, it's difficult to google this issue. At least I've backed up my data and am ready for it to die, if that's what is happening. Thanks.

    You should consider taking the matter up with Apple before your warranty runs out. Problems like that are sometimes hardware related. It could be your Mac needs a motherboard swap.
