Certain menu settings are locked based on the current input signal or preset picture mode to maintain optimal image quality.

  1. Verify Input Source: When using digital connections (HDMI, DisplayPort), options like Phase or Horizontal Position are automatically optimized and locked. These are only available for manual adjustment under a VGA (analog) connection.

  2. Check Picture Mode: If the projector is set to a [Preset Mode] (e.g., Movie, Presentation, Dynamic), parameters like Color Temperature or Contrast may be locked to match the specific scene requirements.

  3. Switch to User Mode: To unlock all manual adjustments, change the [Picture Mode] to [User Mode] in the OSD menu.

  4. Disable Auto-Sync: Ensure that [Auto-Sync] features are not overriding manual geometric or timing settings.


Notes:

  • Tip: Greyed-out options do not indicate a malfunction; they ensure the most accurate 1:1 pixel mapping for digital signals.

  • Note: Enabling advanced features like HDR may also lock basic Brightness or Contrast settings.
