User Manual
4 Using the StudioCal XML schema
StudioCal XML is an HP-designed XML schema that provides detailed control over the display calibration
process. It contains elements and tags that allow you to specify calibration targets for up to three calibration
presets, provide custom preset names, and dene validation patterns to be measured. It also is used to
upload and download calibration LUTs, install custom input names, markers, and user presets, and upload
and download the entire display
conguration.
TIP: A collection of StudioCal XML les is provided on the optical disc included with the display. They can
also be downloaded from www.hp.com. These les can be used directly on the display or as learning tools.
File name and disk format
When a USB drive is inserted into one of the DreamColor USB ports, the display looks for a le named
StudioCal.xml, which it uses for calibration.
IMPORTANT: The display does not look for any other XML les, so the naming must be exact. The le name
is not case-sensitive.
USB drives containing a StudioCal.xml le may be formatted using FAT16, FAT32, or NTFS.
Declaration
The standard XML declaration statement must be on the rst line of the le. All standard encodings are
supported, including UTF-8, UTF-16, ISO-8859-1, and so on. It should be structured as follows:
<?xml version="1.0" encoding="ISO-8859-1"?>
Comments
XML comments are supported and useful to indicate the procedures performed by the XML le. For example,
a StudioCal XML le that calibrates the BT.709 color space preset might include the following comment line:
<!--BT.709 calibration-->
Comments can be placed anywhere within the XML le.
Root element
All StudioCal commands must be enclosed in a <studiocal> root element. The nal command in the XML le
must be a closing tag for the root element. Therefore, the highest level of a StudioCal XML le is structured as
follows:
<?xml version="1.0" encoding="ISO-8859-1"?>
<studiocal>
</studiocal>
