This is with a dual monitor display, Argyll, and a ColorVision Spyder2Express.

If you've only just plugged in your Spyder, there is one preliminary step. Insert the installation disc and retrieve the firmware from it:

spyd2en /media/cdrom1/setup/setup.exe

Then begin to calibrate. There are five steps.

Step 1: finding neutral calibration

dispcal -d 1 -v -q h -y l samsung213t

• -d 1 Display 1 (one-based number)
• -v Verbose mode
• -q h Quality: High (or l for low, or m for medium)
• -y l LCD display (or c for crt)
• samsung213t output file

This step will ask for:

Run at least 1 if you have a CRT or 3 if you have an LCD. If your monitor is hooked up through a DVI then you won't have the ability to calibrate 2 or 4. Then run 5. Then 6: Continue on to calibration. The amount of patches this step will display will correspond to the quality you selected.

Outputs: samsung213t.cal

Step 2: Generating patches for fine tuning

targen -v -d3 -f500 samsung213t

• -v Verbose mode
• -d3 RGB calibration (ie, for monitors)
• -f500 Number of patches to create for calibration. The more, the more accurate. 500 should be max. 250 is probably enough.
• samsung213t output file

Outputs: samsung213t.ti1

Step 3: Measuring tuning patches

dispread -d 1 -v -y l -k samsung213t.cal samsung213t

• -d 1 Display 1 (one-based number)
• -v Verbose mode
• -y l LCD display (or c for crt)
• -k samsung213t.cal The neutral information to base tuning on
• samsung213t output file

Outputs: samsung213t.ti3

Step 4: creating the ICC file

colprof -v -A "Samsung" -M "SyncMaster 213t" -D "Calibration_20090502" -q m -a s samsung213t

• -v Verbose mode
• -A "Samsung" manufacturer
• -A "SyncMaster 213t" model name
• -A "Calibration_20090502" comment
• -q m Quality level (l: low, m: medium, h: high, u: ultra)
• -a s algorithm selection, 's' is default, keep it like that unless you know what you're doing
• samsung213t output file

Outputs: samsung213t.icc

Step 5: apply the ICC file

dispwin -d 1 samsung213t.icc

• -d 1 Display 1 (one-based number)
• samsung213t.icc the input file
