Review Gamma Setting
Gamma settings can be adjusted in two ways, with or without DICOM Gray Scale Standard Display
Function (GSDF) enabled.GSDF-compliant with all contrast settings, but not all brightness settings.
Because of differences in display technology, the 22-inch OLED monitor is GSDF-compliant with all
contrast settings, but not compliant with all brightness settings.
To enable the GSDF mode, in the touch panel, go to Utilities > System > System Display tab and
select Enable DICOM grayscale display mode (GSDF).
If a site’s PACS workstations are calibrated to the GSDF, this setting may help to make the image
appearance more uniform between the Ultrasound system and PACS.
• With GSDF disabled, the monitor still uses a gamma curve that may be selected on the Touch Panel
(for backwards compatibility with sites that are happy with their PACS or may have a mix of older
systems).
• With GSDF enabled on Widescreen Monitors, the gamma button on the touch panel affects the
image, emulating the appearance of that gamma, but does not affect the monitor.
Set Use Wide Screen for… > Single Image to Off.
