Calibrating monitor and settings

Hi all,
Well just received my brand new lenovo l220x monitor to add to my hp zd8000 laptop. I got this monitor primarily for photo editing and am running XP.
Now I am trying to calibrate with spyder2 (says spyderpro 2.2 in properties) and wondering if the monitor has RGB Sliders?
I know it has Kelvin Presets but can't work out it they are indeed rgb sliders or not.
Not sure if anyone has the same sort of package and calibrates also but if you do I would love some pointers/tuition on the subject.
I have calibrated my laptop screen in the past but it is so basic and doesn't have all the controls on the lenovo so that is where I am becoming unstuck!!!
I read somewhere that this monitor doesn't have backscreen lighting either?
Sorry for all the dumbass newbie questions, just like my colours to be spot on so any and help gratefully appreciated.
Cheers, crackennz

This is a very advanced subject which ought to "just work" a little more often than it does. I suggest you try the Adobe User Forums, both for Photoshop and for Color Management. This topic can go on for years. Your choice of Gamma 2.2 & D65 White point is considered professional. That leaves the Color Management nightmare maze in between Photoshop, Apple & Epson. Good luck!

Hardware calibrated monitor and Lightroom 4

Hello everyone,
I have just invested in an Eizo SX2462W with EasyPIX / EX2 sensor (effectively a Spyder 4).
I have put together 3 profiles using the EasyPIX software as follows (based on the settings recommended by the Eizo guide):
1st profile - 6000K, 80cd/m2, Adobe RGB, 2.2 gamma
2nd profile - 6000k, 80cd/m2, sRGB, 2.2 gamma
3rd profile - 6000k, 80cd/m2, Native, 2.2 gamma
I use Lightroom 4.4 to process my RAW files.
As Lightroom is colour managed, my expectation is that when I switch between the 3 profiles I set up, the colour in my photos as seen in Lightroom would stay the same in the normal gamut range (e.g. skin colours). However, when I look at the photo the colours change as I cycle through the 3 profiles (I am looking at a portrait of my 5 year old son and focusing in on his skin tones in particular because I have read that normal gamut should cover the range of skin tones).
For the 2nd profile (sRGB) - this is the least saturated. The pink of his rosy cheeks as well as the rest of his face has a "duller", less saturated colour tone.
For the 1st profile (AdobeRGB) - his skin is more saturated. The pink rosy cheeks are noticeably pinker.
For the 3rd profile (Native) - his skin is even more saturated - looks almost orange. Pink cheeks are definitely even more pink.
The differences I am describing are not huge, but there is definitely a discernible difference as I cycle through the different profiles. So now I do not know which profile to trust when I am doing my post processing to get the right colour!! Which profile is correct??
If I have understood this topic from what I have read to date correctly, broadly speaking, I expected only 'out of normal' range gamut colour to be different between the 3 profiles. I am about to print a whole lot of large photos so just want to make sure I am doing my post processing right....
Many thanks.

Either way, I don't see why you need anything but native gamut, from a color management perspective. The sRGB emulation could be useful if you plan to use applications that are not color managed, and you can't stand the wide gamut over-saturation. Personally I just ignore it and avoid those apps whenever possible.
Even web can be fully color managed if you use Firefox with color management set to mode 1.
One example of a "color-management issue" which I find to be quite vexing happens whenever I wish to view the Flash-based slideshows generated by my photohosting site (Zenfolio.com). Zenfolio's use of Flash for slideshows breaks the color management in normally-managed browsers like Safari and Firefox. So wide-gamut monitor users (such as I) can't display proper color in their own Zenfolio slideshows unless we use an sRGB emulation profile.
Frustratingly, Zenfolio has managed to deal with another Flash issue (i.e., its unavailability) for iOS devices by having HTML5 used for the slideshows if Safari reports the User Agent to be an iOS device. I tried to work around this by having my desktop Mac pose as an iOS 5 iPad (via Safari 's User Agent setting ). This fixed the color but introduced unacceptable screen formatting problems.

Fully Color Managed Application (using calibrated monitor profiles)

Hi,
I'm new to JAVA 2D so I may be missing something obvious - apologies if I am, but I've been trawling the API and web to try and solve this for many hours - so any help would be much appreciated!
I'm trying to write an application to open a JPEG with an embedded colour profile (in this case AdobeRGB) and display it with correct colour on my monitor, for which I have an accurate custom hardware calibrated profile. In my efforts to do this several problems / queries have arisen.
So, JAVA aside, the concept is simple:
a) Open the image
b) Transform the pixels from AdobeRGB->Monitor Profile (via a PCS such as CIEXYZ).
c) Blit it out to the window.
(a) is fine. I've used the following code snip, and can query the resulting BufferedImage and see it has correctly extracted the AdobeRGB profile. I can even display it (non-color corrected) using the Graphics2D.drawImage() function in my components paint() method.
BufferedImage img = ImageIO.read(new File("my-adobe-rgb.jpg"));(b) Also seems OK (well at least no exceptions)...
ICC_Profile monitorProfile = ICC_Profile.getInstance("Monitor_Calibrated.icm");
    ColorConvertOp convert = new ColorConvertOp(new ICC_ColorSpace(monitorProfile ),null);
    BufferedImage imgColorAdjusted = convert.filter(img,null);[I was feeling hopeful at this point!]
QUESTION 1: Does this conversion go through the CIEXYZ (I hope) rather than sRGB, there seems to be no way to specify and the docs are not clear on this?
(c) Here is the major problem...
When I pass imgColorAdjusted to the Graphic2D.drawImage() in my components paint() method the JVM just hangs and consumes 100% CPU.
QUESTION 2: Any ideas why it hangs?
Pausing in the debugger I found the API was busy transforming by image to sRGB this leads to my third question...
QUESTION 3: If I pass an image with a color model to drawImage() does drawImage do any color conversion, e.g will it transform my adobe image to sRGB (not what I want in this case!)?
And if answer to Q3 is yes, which I suspect it is, then the next question is how to make the J2D understand that I have a calibrated monitor, and to tell it the profile, so that the Graphics2D it provides in paint() has the correct color model. Looking in the API I thought this was provided to J2D through the GraphicsEnviroment->GraphicsDevice->GraphicsConfiguration.getColorModel(). I tried looking at what these configurations were (code below). Result - 10 configurations, all with the JAVA 2D sRGB default, despite my monitor colour management (through the windows display properties dialog) being set to the calibrated profile.
QUESTION 4: Am I just off track here - does Java 2D support monitor profiles other than sRGB? Is what I am trying possible?
GraphicsConfiguration[] cfg = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().getConfigurations();
    System.out.println(cfg.length);
    byte[] d;
    for (int j=0; j<cfg.length; j++) {
      System.out.println("CFG:"+j+cfg[j]);
      d = ((ICC_ColorSpace)cfg[j].getColorModel().getColorSpace()).getProfile().getData();
      for (int i=0; i<d.length && i<256; i++){
        if (d[i] != 10 && d[i] != 13){
          System.out.print((char)d);
System.out.println();
Any help much appreciated.
Thanks.

I have had some sucess with this, but it wasn't easy or obvious. The trick is converting the color to the monitor profile and then changing the color model to be sRGB without changing the pixel data. JAI's Format operation does this easily although I'm sure there are other ways to do it. The RGB data is then displayed without being converted to sRGB so that the monitor calibration is maintained. I will answer your questions since I had similar ones.
Q1. Yes the conversion is done using XYZ as it should be.
Q2. I believe paint is just very slow, not hanging. Any color model other than XYZ or sRGB requires conversion before it can be displayed (as sRGB). This is both slow and incorrect for a calibrated monitor.
Q3. Yes that is what I have found, a conversion to sRGB will always happen, unless it appears to be already done as when the color model is sRGB (even though the pixel data is not!).
Q4. It is possible but apparently only with this somewhat strange work around. If there is a way to change the Java display profile to be other than sRGB, I could not find it either. However, calibrated RGB display can be achieved.
Since I have seen many other posts asking for an example of color management, here is some code. This JAI conversion works for many pairs of source and destination profiles including CMYK to RGB. It does require using ICC profiles in external files rather than embedded in the image.

Color settings after calibrating monitor with Spyder 4Pro

Hello, Now that I got my new laptop and finally got a perfect calibration with the Spyder 4Pro , I have a question. Do I leave the color space on Photoshop and Lightroom as they are (Abobe 1998) or use the new profile? I also do a lot of my own prints with a great Epson, do I leave that on the setting as is ( let photoshop manage etc) or use the new profile?
Thanks in advance....

The profile saved by your calibration software is your Monitor Profile and absolutely nothing else..
It has absolutely nothing to do with your working color space or your printer (target) profile.
Monitor profiles are absolutely device-dependent, that means it only applies to your particular monitor unit and nothing else, not even an identical monitor of the same brand and model.
Your working space should be a a device-independet color space, such as ProPhoto RGB, Adobe RGB, sRGB, etc.
Your printer profile, also called target profile, is a totally device-dependent profile for your specific combination of paper/ink/printer.
You need to do an awful lot of reading on Color Management, a subject some of us have spent a very long time studying before we grasp it. A good place to start would be here:

Colors displaying as dull yellowy-green; new monitor and calibration

Just got a new ASUS LCD monitor, and calibrated it with the Spyder 3 Express.
Now when I import a .CR2 file using Lightroom 3 to edit the RAW image, the color is displayed as yellowy-gray and dull. It looks the same when I pull it into Elements 7, unless I remove all color management (which, if I save the image, actually then renders the image colors neon and oversaturated with lots of pink and red tones). If I export the image from Lightroom 3 the image colors are correct and very different from how they look in Lightroom.
I also use the ACR editor with Elements 7 and I am having the same problem there. Upon opening an edited Jpeg or a .CR2 RAW file there, the color is displayed as dull, grayish yellowy-green.
If I view the very same image in GIMP, Picasa or on the web, as long as the colorspace is intact (sRGB), the color is accurate. Not so in Elements or Lightroom.
If you have experience with this problem is it the monitor, the calibration, or Elements and Lightroom? I am beyond frustrated and need to see my colors properly. I have not had this problem before.
Thanks for your time.

I suggest re-reading C S S Simon's and my reply, including the links I provided with solutions and historical explanation – It is apparent you didn't!
Pay your money and make your display choice, but don't blame the wide gamut capable display because you are unwilling to learn how to use the technology advantages it provides!
Please read this factoid:
All Wide Gamut Displays when properly setup to display in a "wide gamut" mode such as Adobe RGB will only display images correctly in color managed applications – PERIOD.
Your Asus display has two factory calibrated modes, Adobe RGB and sRGB, which will only work properly using the color profile provide to you on CD (or downloaded) by Asus – This the monitor profile Asus used when hardware calibrating your specific serial number monitor at the factory. The displays internal LUT contains that calibration information, and there is no way for you to recalibrate it using a Spyder 3 or other hardware calibrator. I am going to paste here three separate solution alternatives I made at the other post – Use only one (1):
Solution 1) Delete your i1 Display custom profile and install the Asus provided PA246Q driver and profile. Then use the monitor's "factory calibrated" Adobe RGB wide Gamut selector mode with Lightroom and other color-managed applications. When using non-color managed applications, switch your monitor’s mode selector to sRGB. Calibration using i1 Display or other hardware device cannot be used with this option. User hardware calibration should only be performed using the monitor's 'User Mode.'
Solution 2) In addition to your Asus PA246Q wide gamut monitor, install a second standard gamut sRGB monitor. Calibrate both monitors separately using your i1 Display unit, which will create separate profiles for each monitor. Use your Asus PA246Q wide gamut monitor only with Lightroom and other color managed applications. Use your second sRGB monitor for with both non-color or color managed applications. You may still have issues properly calibrating your Asus PA246Q monitor with its proper 'User Mode' selection as others have reported, but the results should be better than what you have now.

http://forums.dpreview.com/forums/readflat.asp?forum=1004&message=3908 1965&changemode=1
Solution 3) If none of the above works for you, get rid of the Asus PA246Q and buy a good standard "non-wide gamut sRGB display.

Calibrating monitor, prints, and CAMERA

I have a canon 5d. I custom white balance for correct color in camera. When I see the photo on the back of the camera dislplay the color looks spot on but when I upload to the computer the colors are almost purple. I use and eye one display calibrator for my monitor.
How can I correct this?

Aimee,
The problem is that your LCD screen on the camera is not color or tonally calibrated and what you see on it is not what you get. That's pretty normal for back of the camera LCDs and there's not anything you can do about it.
Are you shooting RAW or in camera jpegs? If you're shooting in camera jpegs, what color matrix have you chosen? You can basically set them to sRGB or Adobe RGB and, if that's what your'e shooting, they should be pretty close when you open them in Ps. If you're shooting RAW, which I really encourage you to do, the white balance you set in camera is only a guide used as a starting point for the raw image processing application - Canon's DPP, Adobe ACR or Lightroom or PhaseOne's CaptureOne. The white balance, along with the RGB working space can be overridden in the raw software to whatever works best for you.
Obviously a hardware calibrated monitor is a must when evaluating digital files. I assume you've done that, right?

Reset graphics and monitor registry settings

Hello, I have connected many different monitors and combinations of monitors either directly or via KVM switch. As a result, these registry keys have a ton of extraneous entries:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\DISPLAY
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Connectivity
The problem is that one of the monitors (a Sceptre X24WG-Naga) is not properly recognized. Sometimes it's identified as a Dell E228WFP, or a Dell 2209WA (both of those monitors are also connected at the same time), or it's identified as "EmulatorMode"
(the ConnectPro KVM switch provides that), or "Generic PnP Monitor", depending on how and where you look. The result is that I cannot use the monitor's native resolution (16:10 1920x1200). The maximum resolution available is 1280x1024
The above mentions registry keys seem to retain a permanent record of every monitor configuration every connected to the computer. I can't tell if the problem I'm having with the monitor is related to these extraneous entries or not. I'd like to (safely)
remove them and start over.
I'm thinking that if I uninstall the NVidia drivers so that the system is only using the laptop's built in display (the laptop is a Dell E6410), then I should be able to delete everything except the standard keys required for the plain vanilla VGA.
Does anyone know what those are, or any other way to get there from here?

Hi Jay,
First of all, I would like to explain the reigstry you mentioned in your post
HKEY_LOCAL_MACHINE\System\GDI\Drivers\Display, by default, GWES loads a driver named Ddi.dll. To change the name of the default display driver, use the
HKEY_LOCAL_MACHINE\System\GDI\Drivers\Display registry key to override the default display driver DLL name.
The registry key should be placed in your Platform.reg file.
For more information about this registry key, please refer to Microsoft article:
Display Driver Registry Settings (Windows CE 5.0)
http://msdn.microsoft.com/en-us/library/aa447504.aspx
Regarding HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration, Please refer to the following forum post:

Please refer to the workaround that the forum post mentioned as following:
Using Sysinternals ProcessMonitor I found that Windows was accessing the following Registry path;
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration
My system had three entries;
DELF003YY7707BR0MUL_30_07D7_6A^9A3774EB79DEE3E3E38496CC7DF4D936

Under each is a tree called "00" two of the keys are
PrimSurfSize.cx
PrimSurfSize.cy
Under "00" was another branch also called "00" two of the keys are;
ActiveSize.cx
ActiveSize.cy
The first two of the configs (ie DELF00... & QHD3...) the above keys were 1440x900,
so they were not involved.
The third (SIMULATED...) were set to 1024x768.
I changed these to 1600x900 and the problem was solved.
Further I changed resolution (via control panel) to 1920x1080, the moving/resize issue returned,
but the lower right corner was set to 1600x900, ie the SIMULATED... settings.
Hope this will help, and please let me know if you have any questions. Thank you.

Monitor and Printer Calibration

I am running a MacPro 4.1 (early 2009). I have older monitor and printer hardware and their related software. Unfortunately, the software will not run because the Mac will not run PPC software. The software has both PC and Mac versions on the CDs. I originally ran these on a PC before switching to Mac. It appears that the manufacturer does not have new or updated software to enable these devices to run on the MacPro, and a Google search has not revealed any other devices that will run on this machine.
My question: Is anyone aware of any new such hardware with software that will run on this Mac?

Check out the blog and topic articles index, and the sections on Lion, RAID, and other issues, plus at the top, "Cloning as Backup Strategy"
http://macperformanceguide.com/blog/2011/20110915_2-LionFullScreen.html
No Mac Pro should be without redundant systems and backup methods.
Definitely not TimeMachine alone, and definitely not when moving to a new OS.
Backup now. Clone you drive. Or just get a new system drive - you will want and need a new OS drive and a backup drive for SL TimeMachine with at minimum room partition set aside for clone.
WD Green 1.5TB $109 makes a good size for both but it is always best to have separate drives / separate backup sets.
Install OS X 10.6.3 and update.
As for "old Sl FILES" you mean your old data? other than Apple Mail and some prefs, should all be the same. And keep your data files off of and on their OWC "data media drive(s)" or something if you don't already, and that makes sense to you. OS / Apps on one, media and projects on 2-3 drives, some external backup drives.
And keep anything you download. Updates, installers, programs, whatever.
Ask Lion Community. There were/are changes in what and how TimeMachine Lion works.
I personally never really had a good warm fuzzy feel about TimeMachine, especially when it was pushed out in "1.0" form in 2007 and had so many bugs and problems even in 10.5.2.
A lack of configuration options and preferences; why do I need to use 3rd party to configure Apple's? So I stick mostly with other programs. To clone, to make backups and archives, to synch.

Cisco Secure ACS 5.4/Monitoring and Report Viewer - SNMP Settings

Hello Everyone.
I hope this is the right forum for my question.
We just purchased 8 1121 ACS 5.4 appliances. I have some familiarity with the older 1113 and 1120 appliances running ACS 4.2. So I have a lot to learn.
Right now I'm trying to understand the Monitoring and Report Viewer System Configuration. I set the SNMP V2 read comm. string to the same string I configured from the CLI.
etc-labacsb1-1/admin# show runn | inc snmp
snmp-server contact "ACS1121;XXXXX"
snmp-server location "B1 Lab"
snmp-server community XXXXXX ro
1) It was not the same string as configured on CLI. Does setting this give me access to query more than system type or server type MIB objects.
2) Can you provide an example? (for example to query a switch - snmpwalk -v 1 -c XXXXXX hostname 1.3.6.1.4.1.9.9.43)
3) What is the MIB object tree OID (1.3.6.1.4.1.9.???) for these ACS appliances?
Thanks in advance.
Ray Westphal
EHI

that's correct. here is what we have in ACS 5.4 for snmp.
ACS 5.4 supports Simple Network Management Protocol (SNMP) to provide logging services. The SNMP agent provides read-only SNMPv1 and SNMPv2c support. The supported MIBs include:
•SNMPv2-MIB
•RFC1213-MIB (MIB II)
•IF-MIB
•IP-MIB
•TCP-MIB
•UDP-MIB
•CISCO-CDP-MIB
•ENTITY-MIB

Calibrating PAL CRT monitor and Macbook Pro Screen

Hi,
Can anyone offer any tips on how to calibrate a monitor and the macbook pro screen for PAL colours.
On my monitor you can adjust the brightness, contrast and the colour temp (which is set to 6500). You don't seem the be able to adjust the colour, for example make it black and white, unles you can do that by lowering the colour temp.

... but the MXO won't help the OP with his MacBook Pro screen.
True, but he did say that he wanted to not only calibrate the MacBook Pro, but another monitor as well...
Can anyone offer any tips on how to calibrate a monitor and the macbook pro screen for PAL colours.
Just offering a suggestion...not knowing what that other monitor was.

Dual monitor color settings seems to be messed up cs4

Hi
My daughter has this setup
AMD 9550 quad 2.2mhz machine, Windows 7 ultimate. latest updates
ATI Radeon HD 5700 gpu card (latest driver)
Two LCD monitors
          1. LG 2361V HDMI (main)
          2. Cintiq 21UX (Extended)
Both monitors are calibrated, and have the latest driver updates. It does not matter which monitor is the main one.
PS cs4 also has the
1. If i load a photo in fireworks and drag the application back and forth accross the two monitors, the image looks virtually identical.
2. If i load the same photo in PS (cs4 11.0.1) and do the same, the image looks perfect in the LG but immediately darkens when on the Cintiq.
          a. The darkening is not instantanious. It looks good for about one second before it changes.
          b. If I hover the image between the two monitors, then the darkening only is applied to half of the image.
3. If i change the preferences to not "color match" (in the performance->open GL) then the image does not darken and it remains loyal to the color profile in place. But!!!! the navigator and color selection tools remain darkened while on the Cintiq. So if she chooses a color from the tool, it paints a different color on the canvas.
          a. If I modify the color settings, then the modification affects both monitors display and the difference issue does not go away.
Ideally we want to be able to select a color from the palette and have that color be what is painted onto the canvas. We also want the image to appear as similar as they do in fireworks.
While Color Matching is checked:
On the cheaper monitor, the image and the navigation pane always has the same color appearance. when i change the color profile, the change is reflected in both the canvas and the navigation pane.
The same is true on the Centiq, but the image and navigation pane is always darker than on the other monitor.
While Color Matching is UNchecked:
The color selection tool and the navigation panel are affected but the canvas is not. But the two monitors canvases match.
So. in order for the navigation and color selction tool to match the canvas, the color matching needs to be checked.
But this creates the darkening on the cintiq. No matter what profile i choose, the cintiq is too dark. and photoshop is doing it because fireworks does not do this.
How can i set it up so that all the colors are true to the profile, and match the nav and color tools?
Thank you
Any ideas will be appreciated.

Thanks

It sounds as if the monitors are using two quite different profiles, which may indicate the calibration is off a good bit on one of them and the profile was generated to compensate. The clue here is that you see a change when you move a document from one to the other, and that temporarily (while an image crosses both monitors) you see quite a difference in it.
If you drag an image in a non-color-managed application across both monitors, so that specifically part of it is shown on one and part on the other, how different do they look?
Using fireworks or MSpaint or IExplore, an image looks pretty much exactly the same on either monitor as well as when spanning accross both.
The two monitors are clibrated so that all colors match on both monitors.

The Cintiq has a better contrast ratio so the whites are slightly brighter.
But!!! If the moitors were not calibrated, then a fireworks image would look different on each screen. In fact they look exactly the same on both.
Even when the image spans accross the two screens.
It is only Photoshop that darkens the part of the image that hangs onto the Cintiq. And it is very dark.
Even in the famed "Monitor mode", the image is much darker than is is in IIE or MSPaint or Fireworks.
I dont want to disable the color profiling, as it is important to see what the target will look like.
But i do want to see what the target will look like! right now it is way to dark. No matter what profile i choose.
Also my examples are more to demonstrate the comparrison between the two monitors, but the goal is to get PS CS4 to work on the centiq. It would be nice to have the navigator and some panels on the other monitor and have the colors match, but more important is to have the colors on the cintiq look normal at all!
Thanks so far. but we are still messed up.

Color Management - How get monitor and printer to match?

We have not been able to get what we see on our monitor and what we get out of our printer to reasonably match - the prints are always significantly darker than the monitor. It makes working on Photoshop Elements (both 5 and Trial 7) virtually worthless, as we can't rely on getting out what we see after making adjustments to our photos. We bought a Colormunki to calibrate the monitor and create paper profiles, but that didn't solve the problem. We have worked with the Colormunki people for weeks and haven't made any progress. We are sure that we are using the correct settings in both Elements and the Printer to have Elements control color and apply the ICC profile. We have an Epson Stylus Photo R2400 printer and a Samsung SyncMaster 2253BW monitor. We think, at this point, that the monitor maybe the problem. Apparently it is known for its excessive brightness - as even with the calibration set for very low brightness, the problem remains. Anyway, our question is whether anyone can think of a solution or, if not, can recommend a monitor more likely to give us a reliable match to the printer - what photographers/photoshop users use?? alternatively, any ideas where we can contact people who might be able to help???? Thanks in advance for your help.

I'm having the same problem with a Syncmaster 226CW Elements 7 and a Spyder3. I've cal'd the monitor to 6500 K and 90 cd/SQM but the prints are still very dark on my Canon MP520. I've also tried letting Elements manage the color and selected one of the Canon profiles -- again no luck. Several emails to Canon just gave me advice to clean nozzles and ck patterns -- no help from Canon so far. Pondering what to try next....

Wide gamut monitors and prepping files for website

This question is for those who are colour management savvy and understand the issues with prepping sRGB profiled files for the web. I thought I was pretty good at this stuff, but found out I'm not as good as I thought....
Problem - prepping my images for my own website using a wide gamut monitor (NEC 2690 with SpectraView calibrating software).
Issue - when viewing said images after placing in website, on wide gamut monitor, reds are over saturated and colour not as it was in prepped file. My "other" monitor is a laptop screen (profiled, but still......). I do need to get an sRGB monitor (the NEC "regular" 24" or an Apple), but funds are tight right now.
I'm pretty sure all my workflow is good - profiled monitor (gamma 2.2), colour settings in Photoshop (I change over to n. American web/internet work space when prepping files for web), converting files to sRGB etc.
It's when I go to Save For Web.
I am embedding the ICC profile (for Safari and Firefox users), but when previewing the image in the browser (Safari) the image is as described above - over saturated in the reds etc. It looks the same after load onto my website and viewing in colour managed browser (Safari and Firefox).
Is this simply an issue of the wide gamut monitor "stretching" the available sRGB numbers to fit the (almost) aRGB space on the monitor?
Or is this something to do with the Monitor RGB (or is that the same thing......)????
Or am I missing something else???
any explanation of what is happening from a colour management point of view - and how best to deal with it - would be greatly appreciated. Also any books/articles/threads.
Thanks!
Oh yes, I'm using CS3.

I'm using the Spider Pro to calibrate my monitor and everything looks great in Photoshop, Illustrator and Firefox 3.5 with color management turned on. But the lack of color management in Fireworks is still a problem because I'm not seeing the colors the way they will look on most people's monitors. I can't design unless I can see what most people will be seeing.
Fireworks should be using that ICC profile that my calibrator generated but instead its sending the colors to the monitor raw. This is what's causing the over-saturation. This really is quite unacceptable.
