A check mark (..) means it is switched on, a cross (..) means it is off. When switched on, the OSD disappears automatically after 300 seconds of inactivity. ALC ALC (ambient light compensation) is a system that adapts the panel light output automatically, based on the ambient light measured by the ALC sensor at the front of the display. Here you can adjust the ALC parameters. These are the ALC settings: min Light...................This is the panel light output that corresponds to the minimum ambient light, measured by the ALC sensor. User manual MIVD 1218 max Light..................This is the panel light output that corresponds to the maximum ambient light, measured by the ALC sensor. min Thresh ...............This is the minimum value of ambient light. Below this value, ALC will remain inactive. When the measured ambient light reaches this value, the panel light output will be set to the min Light value. max Thresh ..............This is the maximum value of ambient light. Above this value, ALC will stop controlling the light output. When the measured ambient light reaches this value, the panel light output will be set to the max Light value. Scan mode The memory of the display contains maximum 200 fixed and 28 programmable scan modes. When you connect a video signal, the display checks in the memory for a matching scan mode. If it finds one, it selects the corresponding settings and parameters from the memory. If it does not find a matching scan mode, the display uses default settings to display the image. When you make adjustments and save the changes, the current scan mode is saved as programmable scan mode. If this happens while all programmable scan modes are occupied, the oldest programmable scan mode is overwritten automatically. The Scan Mode menu contains the following function: Find next mode.........Select if you wish to select another scan mode from memory that matches the incoming video and sync signals. The number displayed in the OSD is the number of the actual scan mode’s memory location. Factory reset Can be used to re-initialize the display. Actual mode .............Restores all factory parameters for the current programmable mode. All modes..................Restores all factory parameters for all programmable modes. Control wheel This function allows you to disable the control wheel function so that the on-screen display cannot be used. User manual MIVD 1218 To disable the control wheel function, set the Control wheel function to Off and exit the on-screen menus. To enable the control wheel function again: 1 Unplug the power supply from the display 2 Click and hold the control wheel while plugging in the power supply again 3.9. Service This menu is for service purposes only. User manual MIVD 1218 4. Maintenance Panel Take care not to damage or scratch the panel. Clean with a soft woolen or cotton towel. Use a watery solution or a mild commercial glass-cleaning product. Cabinet Do not use chemical cleaning products, benzene, toluene, xylene or other solvents. Clean with a soft cloth dampened with mild detergent and water. Repeat with water only and wipe dry with a dry cloth. Removing dust from the rear of the glass panel It may be possible that dust particles have entered the display and are stuck to the rear of the glass. We recommend to let this cleaning procedure be done in a BARCO service center. However, when really necessary, you can perform the cleaning on site if you can work in conditions that are as clean and dust-free as possible. This is to avoid more dust entering the display when opening it. To remove the glass panel: 1 Switch off the display. 2 Tilt the panel. 3 Unscrew the 4 sunken screws at the rear, fixing the glass panel and bezel. 4 Remove the bezel with glass panel. Cleaning instructions: - Dust, fingerprints, grease etc. can be removed by using a soft damp cloth (a small amount of mild detergent can be used on the cloth, NOT solvent). - Do not apply liquid directly to the LCD surface as excess liquid may cause damage to internal electronics. - Take care not to touch the I-guard light sensor on the LCD panel. User manual MIVD 1218 5. Troubleshooting Calibration not successful After an unsuccessful calibration, the message “Failed” appears on the screen. Possible solutions: - Use another test pattern for performing the calibration. The text in § 3.4, Calibrating the display , explains what test patterns to use. - Check the quality of the signal source and signal cables. Poor video signals or cables can result in unsuccessful calibration. Pixel Faults Permanently dark or bright pixels can happen to TFT displays. 20 or less permanently dead pixels do not make out a good case for exchanging the unit. Please contact our Customer Service Department if the number of pixel faults exceeds the above-mentioned figure. User manual MIVD 1218 6.
