The Settings tab contains a number of parameters that can be set for the clips in your OpenEXR decoding session. These settings appear under the Format tab, and are the staging area for the OpenEXR settings. You can additively load presets, or change the settings manually. The settings are not applied until you click the Apply button.

Settings that are not changed are greyed out. Clicking one will activate all in the group. Settings that are not enabled will not be applied.

When you are done adjusting, click Apply to apply the settings to the selected clips in the list. The settings can be applied to all of the clips or to individual selections.
