那是条件显示的：

KDE/kscreen/blob/master/kcm/ui/OutputPanel.qml#L22


      
          import org.kde.kitemmodels 1.0
          
          import org.kde.private.kcm.kscreen 1.0 as KScreen
          
          Kirigami.FormLayout {
              id: root
          
              property KSortFilterProxyModel enabledOutputs
              property var element: model
          
              readonly property bool hdrAvailable: (element.capabilities & KScreen.Output.Capability.HighDynamicRange) && (element.capabilities & KScreen.Output.Capability.WideColorGamut)
          
              signal reorder()
          
              QQC2.CheckBox {
                 Kirigami.FormData.label: i18nc("@label for a checkbox that says 'Enabled'", "Device:")
                 text: i18n("Enabled")
                 checked: element.enabled
                 onToggled: element.enabled = checked
                 visible: kcm.multipleScreensAvailable
              }

具体条件在：

github.com

KDE/libkscreen/blob/master/backends/kwayland/waylandoutputdevice.cpp#L432


      
          void WaylandOutputDevice::kde_output_device_v2_rgb_range(uint32_t rgb_range)
          {
              m_rgbRange = rgb_range;
          }
          
          void WaylandOutputDevice::kde_output_device_v2_name(const QString &outputName)
          {
              m_outputName = outputName;
          }
          
          void WaylandOutputDevice::kde_output_device_v2_high_dynamic_range(uint32_t hdr_enabled)
          {
              m_hdrEnabled = hdr_enabled == 1;
              if (version() < KDE_OUTPUT_DEVICE_V2_CAPABILITY_BRIGHTNESS_SINCE_VERSION) {
                  // make the capabilities API be consistent with older versions even if the protocol isn't
                  if (m_hdrEnabled) {
                      m_capabilities |= KDE_OUTPUT_DEVICE_V2_CAPABILITY_BRIGHTNESS;
                  } else {
                      m_capabilities &= ~KDE_OUTPUT_DEVICE_V2_CAPABILITY_BRIGHTNESS;
                  }
              }
