| + | In case you need something not mentioned above, please contact the helpdesk and check whether they can provide it. |
| − |
| |
| − | # Make sure the screen has been on (not in sleep mode!) for a while (30 min.) and thus is warmed up.
| |
| − | # Plug in the calibration device in a USB port, and place it in the middle of the screen, which you can tilt backwards so the device stays better in place.
| |
| − | # Start the Lacie Blue Eye Pro calibration software.
| |
| − | # Click Settings, make sure the following settings are selected:
| |
| − | #* Gamma: 2.2
| |
| − | #* White point: predefined; 6500K
| |
| − | #* Luminance: absolute; 120
| |
| − | # Click Calibration in bottom right corner.
| |
| − | # Before calibration will start, you get the possibility to adjust brightness, contrast and color directly on the monitor. These steps are not really necessary and can be skipped, as the calibration process will usually correct for this anyway. However, if you discover that the calibration process does not result in the desired values (e.g. a white point lower or higher than 120 cd/m2), you should play around with the monitor settings to get as close to the desired values (see step 4) as you can. For now: click next three times.
| |
| − | # You will get an overview of the settings with which the monitor will be calibrated. Click Start Calibration to begin with the calibration.
| |
| − | # Sit back and relax till the calibration is finished. This can take 5-10 min. Click save once it’s done.
| |
| − | # Click Test and report and wait till the measurements are done. Check if the reported devations of gamma, white point and color temperature are less than 2% and the reported dE values depicted on the right (the graph with the colored bars) are all well below 3. If the white point deviates more than 2% from 120 cd/m2, you should play around with the brightness and contrast settings for the monitor and recalibrate to get this right. Always run a test and report after a calibration, to determine if the screen emits the desired values for gamma, color temperature and white point.

| + | Also, let the Lab coordinator or the research assistant of the respective lab know if you have to change some settings (e.g. monitor contrast, distance to screen, etc...) for your experiments, so that the changes can be set again to default for other experiments. |
