Problem with calibrating two monitors...

Yes
I have calibrated my mac, along with the external Dell display.
I did it at first with the EyeOne LT of digitalfailures :p (Must return that to you some day!)

Yet I couldnt get them the 'same'. The Dell always had a red tint to it, and the mac more blueish imo (in comparison anyway).

Well I did it the other night with the travelling Spyder3 Elite...
And the results are again...well, I'll show you a photo

That was the camera metered on one of the screens, set to AWB. No PP correction except resizing etc.

Here's a 100% crop

Why the chuff won't they both look the same? I thought this was what calibration is supposed to do?

I must admit photos look similar on both (not the same, but closer than i'd expect, given the colour tint you can see above).
It was the same when I was on windows too. I always thought the Dell had a bit of a red tint to it, even after calibration.

Thoughts?
 
perhaps, due to differing technologies - thats as close as the two screen can get?
 
Here's a screenie of that shot open with the colour sampler tool used

Mac = almost spot on... :)
Dell = chuck it in the bin, it looks murky ;)
 
I've never used an Eyeone (or a Mac) but had the same issue when using my Spyder.
Even though there are profiles for both monitors, the Spyder overwrites both versions when doing the second calibration...unless it has been renamed after the first monitor has been calibrated.

Maybe you're getting a similar problem?

I don't think I am. I've clearly named both profiles differently.
I'll go back and check in a mo.

What I used to do with the EyeOne, was attempt to adjust the Dell monitor with the monitor controls....to try and get it balanced before I calibrated.
I never could get it right.

Now I just leave the monitor on default settings, and set the calibrator going...which by rights, is what it's there for, to compensate for such.
 
OK it's on a PC . I've a Gateway 24" main monitor and a Dell 19" secondary, and I can't get them to mach either. But as the Dell is used for LR secondary function and Photoshop tools its not so big a deal


Update

Just spent some time trying to match the Dell to the Gateway. Reasonable colour match but in order to get the brightness to match the contrast is down 0.2 on the Dell which you can just detect on side to side comparisons. However it's a good colour match
 
I had a similar issue with my Macbook and Sony external screen, I sent the profiles off to ColorVision support and they had a look at them and were able to overlay them in some 3D diagram to show that the external monitor could display a much wider range of colours than the Macbook monitor.

I can try to dig out the graphic later if it helps.

I have 2 monitors and use an i1 for calibration, but i run Coloreyes Display Pro HERE, Using anything else I couldn't get a match close enough for me.
It works in that you profile 1 monitor then run the software on the second monitor and it will match it as close as it can to your profile for the 1st monitor. It lets you select an absolute black point, which is fundamentally critical when trying to match 2 monitors together, or you will have problems.
Ive been using it for about 2 years now and its great.

I have matched an apple 30" ACD to an Ezio 24" and also to a 24" Dell with great results, i found the dell had slightly less tonal graduation and was slightly off on its black point, but was still good enough for photo editing.
 
I'm going to ask the obvious - before you started the calibration what colour temp were both monitors set to? The difference here looks like the temp was different and the calibration has done the best it can to bring them in line to the same target.
 
Marcel,

I have just taken delivery of the Spyder 3 Elite and after calibrating I had exactly the same result as yourself with my 19" CRT and 17" lcd. The latter was distinctly blue and I was so disappointed. I'm using a PC and Microsoft's color applet which allows two profiles to work in my Windows XP. During the calibration the menus caused me to save more than one named profile and I think that I had chosen the wrong one in the Microsoft Color applet so my LCD desktop backgroung was blue instead of 18% grey.

If however I did not chose the wrong profile then all that was required was for me to shutdown/startup/shutdown and when I restarted the desktop was grey and matches the crt.

My only gripe is that if the ambient light compensation is used I cannot get my lcd bright enough for the room ambient light level as measured by the Spyder (175cd/m2) conditions and the software gives an error saying the the profile cannot be made.

BTW I bought the Spyder 3 Studio so I also have the Spyder 3 Print printer profiler which is working well.

Beemer
 
Is the Dell one of the newer models with the wider gamut?

It seems this is a common problem with wide gamut monitors as I've just found out with my about to be returned Dell 2408.

Basically the wide gamut means extra saturation, especially in the red and greens and makes calibration a nightmare if your working with sRGB.

The Dell does have a sRGB mode but it's awful and calibration is dire as a result (flat colours and very undersaturated blue).
 
Seems my Dell had a slightly more serious problem too...

Strong lightening on the left and oh so many colours in what is supposed to be a grey background. Back it goes tomorrow...
 
Ouch! That's not good at all.
My two monitors....still has a reddish tint on the dell, and a more blueish tint on the mac. Which one is correct? I'd like to think the mac, but it looks too blue to me....but then again, that's because it's next to the red Dell.

So at the moment I'm carrying on processing on the mac, and just making sure that all colour corrections are done on the mac. The other monitor isn't that much out now that I've gotten used to it. While whites look quiite different. Actual photos don't look much different...if that makes sense?
 
The red tint is the same problem I had and is a direct result of the wide gamut. At the moment I've calibrated using native white point to try and keep it under control. I've just ordered a replacement, the Hyundai W241 which is based on the same panel as the Samung 245T (s-pva) so fingers crossed that one is ok.

Google "2408 calibration" and you'll see lots of people having similar problems with calibrating the Dell, pity really :(
