Hi, I need to upgrade to the dual monitor version, so my Spyder 3 Express is up for grabs, if you're interested drop me a message. It's boxed and in vgc.

Remember that for Spyder Pro or Elite to work correctly on a dual monitor set-up each screen must run off its own graphics card unless your card can store and manage two calibration profiles.

Hi ash, thanks for your post.  I'm running a geforce gtx660 ti - single graphics card running both monitors.
It allows seperate profiling of each monitor through the Windows 8 colour calibration so I assume (hopefully correctly) it will also support this on Spyder?

I'm not sure if that will work - I have two GTX 660s in my computer so I can have both monitors using the HDMI outputs. I'm pretty sure the cards (individually) won't hold two Spyder profiles. But I'm by no means a techie, so this is probably something that Nvidia and/or Spyder would have to answer for you.

In case anyone should check through this thread in the future, Ash is correct, one card (or the card that I have, see above) will not hold two profiles, even though one card can drive 2 monitors.
The calibration tool will recognise that you have two displays that need calibrating, but when it tries to calibrate the secondary display, the adjustments are made to the primary display.

I splashed out on a spider 4 pro to solve my monitor calibration problems. Unfortunately it does not seem to be on the same wavelength as my editing software which I have also calibrated. With images looking slightly different on both, which one is correct? My computer monitor which has been calibrated using spider 4 pro, or my editing software Corel paint shop pro 5? Any help from you technical wizards would be much appreciated.

Ok, here is the slightly technical answer. Many people call the process that is carried out with a Spyder etc "calibration". This leads to a lot of disappointment and confusion.

The full terminology is "calibration and profiling". The process of calibration examines the response of the uncalibrated monitor to known colours by measuring the display with a device such as a Spyder. The software then calculates what changes are needed to get the display as close to correct as possible. It stores these changes in files which are loaded into the graphics card's lookup tables when the computer starts. The tables are used to adjust the displayed colours as far as possible. This part of the process is called calibration.

The other and very important part is profiling. Once the display is calibrated, it is still not at all accurate because there are things that lookup tables cannot achieve. The calibration and profiling software therefore generates a "Profile" of the calibrated monitor. In somewhat non-technical language, this profile represents how incorrectly the calibrated monitor displays colour. The profile contains information that cannot be applied by lookup tables. This information can only be applied by colour-managed software such as Photoshop, Corel etc.

When you display your images on the calibrated monitor using colour managed Corel, the information held in the profile is applied to the already calibrated monitor.

Non-colour managed applications do not apply the profile and what you see is the result of calibration alone. With colour managed software, you see the reult of calibration and profiling.

In slightly more technical form, the reason for the difference is that lookup tables apply to each of the three individual colour channels in isolation and cannot "mix" colours, e.g by adding a bit of blue to red. Profiles, on the other hand, can mix the three colours in a manner which is implemented only in colour-managed applications.

I've owned both Spyder and Eye1 Display Pro and personally prefer the Eye1 range.

Thank you very much for your technical answer to my question, much appreciated.

If I understand you correctly then what I see in Coral after editing is actually correct?

Yes, that's right. What you see in Corel is the more correct. I put it that way because not even the profiling process can achieve perfection (even if perfection could be defined, which it cannot).
