Colour Calibration for Dual Head

Hi There.

I have the Monaco OPTIX gizmo from x-rite, and two CRTS.
I use a Nvidia Quadro NVS.

One monitor is a 17" Viewsonic, the second a 19" MAG.

They are both of differing age and quality.

Im having trouble working out what I need to do.
Monaco says I need to drag it onto the monitor i want to profile, which is easy enough to do, So now i have two profiles, one for each monitor.

Where Do I Apply the profiles? I assume it cant be the regular Display Propertys > Settings > Advanced > Colour Management because that only applys a default one.

I think It needs to be in the nvida settings somewhere, and there is a spot for colour profiles on each monitor - but when I apply it, something looks really wrong!

At the moment, I have no profile set in the Display Propertys > settings > advanced > colour management - and my first display (17") looks right. Its warm, but 6500k is warm!
Please Help! Thanks.

Hello

What OS are you using? I seem to recall that in Windows XP it is not possible to have two monitor profiles. I tried this with a Matrox card driving two LCD monitors and could not make it work.

Matrox told me it was an operating system problem; perhaps you could contact NVIDIA and see if they have a solution

Ugh. Not exactly what I wanted to hear.

Im running windows XP. Surely in todays time there is a way! Ill go see what info I can get out of Nvidia.

Hello again

I just googled "two monitor profiles xp" and got the following which looks interesting:

It needs the xp color applet which I have and this seems to offer the possibility of two separate profiles.

I am still working on this

Wow, thanks very much! I had googled lots but missed that.

Im investigating now, Thanks!.

Woohoo!! Im fully colour calibrated now.

with a few small changes, my workflow will finally be completely colour managed. I have the profiles from the printer, and all their instructions. Its working a charm. The colours match finally on my two CRTs.


Geoffrey, thanks very much for your help! I would have just about given up if I never found that link.

Hello

It's a pleasure to help and your question prompted me to have a go at getting both my monitors calibrated. It's strange that the display properties in control panel will only allow the same profile for both screens but the color aplet over-rides that.

Still, it seems to work

I removed the profile from the display propertys applet.

Best of luck,

Matt.

if you have the nvidea software installed.
right click on screen, pop up menu should show an option 'NVIDEA Display' with an arrow to a sub menu to each of your monitors. choose one, when the mouse is over the popup a menu should pop out 'colour correction' is the option you want. then 'import' your icc file. repeat for the othe monitor.
hope this is useful

I solved the problem calibrating only the center diplay with the Spyder, and let the other two alone, just setting them in a visual way I always have the picture in the center monitor, and if the side ones look different, I don't really care

It also depends on your display card...

e.g. the Matrox G550 can only handle 1 profile, and is unable to apply it to the 2nd monitor output

But the Parhelia-based Matrox P650 and above can apply profiles to each monitor output. However you're still limited by the XP issue - but it does at least mean you can have the same profile used on both monitors, and if they're identical LCD's chances are you'll be much closer than you were before.

Great link to the MS colour applet - this looks like it completely solves the issue with an appropriate display card - many thanks!

Hello

It is true that the G550 only handles one profile but the xp color applet seems to overide that restriction.

I have two different monitors on a G550 and have used an Eye-One display to create a profile for each monitor.Whichever one is created last appears as the default profile for both monitors in the display properties - the Matrox G550 can only handle one profile.

But with the color applet, I can assign a different profile to each monitor and if I get them the wrong way round there is an obvious difference so I assume that each monitor is being "driven" by a separate profile - does that make sense?

Anyway, a picture in CS dragged across both monitors appears very much the same in either screen which it did not before I used the applet.
