You get a live DVD (Fedora) with the calibration program and some user notes. |

The device comes with a strap to hold it against the middle of the screen, and |
| 9 |
a 6' USB lead. The measuring process is straightforward, though complicated |
| 10 |
for me by the fact that my screen is LED, not LCD. Still, I told it to treat |
| 11 |
it as an LCD and the result, though a bit bright for my eyes, appears accurate |
| 12 |
enough. It also knows about CRTs and projectors. |

Once the calibration is complete (about 10 minutes for the standard |
| 15 |
calibration) you have to copy the .icc directory from ~/.local/share to a USB |
| 16 |
stick or something, then reboot into your usual system and double-click on the |
| 17 |
file in your GUI file manager. That transfers the data to the monitor, |
| 18 |
apparently permanently. |

Simple, once you get out of the habit of using the CLI. Well, it would be, |
| 21 |
except that I had to run: |
| 22 |
|
| 23 |
$ Find / -iname \*.icc 2> /dev/null |
| 24 |
$ mv .local/share/icc . |
| 25 |
|
| 26 |
Then I could see the icc folder in the file manager and drag it to the USB |
| 27 |
stick. |

As for double monitors, the calibration program on the DVD asks you to choose |
| 30 |
the monitor to calibrate, so it can detect more than one at a time, but I |
| 31 |
don't know how transferring the .icc in the main system would work with two |
| 32 |
monitors. You might have to download and install the client tools. |
