my guess is he bought it, plugged it in, ran the software and probably did not read the instuctions etc. Things like setting brightness levels etc back to the default on the monitor before starting, or having the monitor on for at least 30 minutes so it warms up properly before undertaking a calibration. It is not as simple as turn computer on, install software and run it. Following the directions (which for some blokes is impossible) will lead to good results.
