I don't know whether this is the case with other programs, like Photoshop, but the Corel Paint Shop Pro X I use has a relatively simple calibration routine built into it. Before I used it, images on my home computer would look markedly different than when the same images were viewed at the office. Now, after using the calibration utility on both computers, the images look quite similar.
The calibration affects images viewed with any program on the computer - not just Paint Shop Pro X. You calibrate the image by adjusting the monitor's controls.
The license for Paint Shop Pro X is good too - as long as the software isn't being used on both machines at the same time, you can install one copy, on both machines.
