Due to he fact Eyefinity makes all 3 monitors one and calls it a generic PNP

I loose my profiles from Spyder Pro and i cant calibrate each monitor sperately anymore.

this is a MAJOR problem as without eyefinity on my display port monitor is flashing and tearing like a biatch but with eyefinity on its perfectly stable and fine.

anyone know a way to fix this?

I don't have Eyefinity (yet, where is MD230??), but I know some about color calibration and screens.

I see that you have two wide gamut and one sRGB screen, so I assume that its the white point you are trying to match?

There are then two options, one that might work and one that works, but is a bit tricky and can produce some banding if changes are too severe according to gamma curve/tonal response curve.

Option 1:
Spyder uses its own lut loader. This needs to be removed from startup folder on the start menu. After that, you need to go into windows own color management and assosiate the .ICM files with each monitor. Upon restart, windows will load it into the GFX LUT. I don't know if the ATI cards have room for 3 different LUT profiles though.

Option 2:
Remove all profiles and use the standard srgb for all screens. Restart.

Make a custom color settings yourself within the monitors OSD/OSM. I think that Spyder 3 supports this, spyder 2 does. I have spyder 3 elite, but I use it with spectraview 2. The key to get target color temperature (White point) is to adjust the R (red) G (green) and B (blue) sliders so that the mix gives you correct white. It works like this:

If you adjust red up, green and blue will go down
If you adjust green up, red and blue will go down
If you adjust blue up, green and red will go down

Each color has a range from 0 to 255. Any reduction to this range reduces the amount of colors, so stay as close to 255 on each primary as you can. Minor adjustments won't be visible as in loss of colors.

Your 2407 srgb screen will never be close to any of the wide gamut screens in colors (255 is a different shade on that then 255 on the wide gamut screens), but you can get the white to match.

I have a similar question with the eyeone pro(the latest). I am just not sure how to calibrate all 3 screens to match the same, I have tried, but have been unable. My screens are u2410's.

PS - Not really sure what you need to know, so if you need some information let me know.

Atm i have 2x 2408wfps, Its virtually impossable to get them the same, set them both as custom in the menu then SRGB in Spyder and they have 0.25 diff on each monitor but look so diffrent to my eyes!

the HP lp2475 looks more diffrent! darker whites and lighter blacks, but colours wow so much better.

They are alot closer then i could have ever made them anyway so atm im happy, i found that when eyefinity is on the monitors keep there seting bar the HP one.

Will keep at it and try the things you suggested

The screen is tearing due to a bug that downclocks idle speed too low when you have the card overclocked and 2+ monitors, there's a few ways to fix it, either set up multiple profiles with a non-OC'd profile, turn off the OC manually, use RivaTuner or something to force 400/1200 clock, flash the bios with modded clock speeds.

First of all, which settings do you have on your screen? U2410 can emulate sRGB colorspace and also use its native wide gamut.

Secondly, what differs from your screen? Color of white (white point)? brightness? etc.

If Eyefinity doesn't accept profiles loaded into the lut for each screen indiviually (I think that catalyst 10.3 had extra support for this), then you should focus on calibrating the screens themselves.

If you do colorcritical work on the screens, you can load manually in programs like photoshop which profile to use. Then you use the Eyeone to calibrate the screen, but select which profile within photoshop.

@Phoenixdancer: The lp2475 uses an IPS panel if I am not mistaken, while the dells uses a PVA panel. Thats why you see the difference in color and black.

As for white, its a matter of brightness and whitepoint, so this can be matched much easier.
