This means that after switching off the display or after switching to a different memory scan mode, the value for contrast and brightness is restored to the calibrated position. - The calibrated position for contrast and brightness is determined by calibration of the video levels (see § 3.4 below). In case you feel unsatisfied with the current calibrated position, you need to repeat the calibration. The proper way to do this, is to use the automatic calibration routine. However, you can also manually change the calibrated positions: The Manual black control changes the brightness calibrated position, Manual white changes the contrast calibrated position. 3.3. Controlling the light output The Light Output control adjusts the backlight of the flat panel. To control the light output: 1 Turn the control wheel to display the Light Output menu. ***MAIN MENU**** Light Output 136 User manual MIVD 1218 2 Click the control wheel to enter the menu. 3 Turn the control wheel to change the light output value. 4 Click the control wheel to confirm the change of the value. *IIIIIIIII..................* Light Output 136 5 Click and hold the control wheel for a few seconds to exit the menu. Note: Unlike the contrast and brightness values, the changes to the light output setting are saved immediately after changing the value. When you switch on the display, it comes up with the same light output value as before switching it off. 3.4. Calibrating the display* *Not in DVI mode When do you need to calibrate? It is necessary to perform the Level and Phase calibrations in the following cases: • The first time you use the display • After connecting or selecting another video source We recommend you use the automatic calibration routines only. The manual calibration controls are intended for advanced users who wish to fine-tune the automatic calibration result. Required test pattern To obtain good results with the automatic calibration routines, it is necessary to have a good image on which to perform the calibrations. For Phase calibration, the pattern should contain sharp black-white transitions, like a line pattern or characters. For Level calibration, the pattern should contain parts that are completely black (0% video amplitude) and parts that are full white (100% video amplitude). For Total Autoset, the pattern should contain: - sharp black-white transitions (see above) - 0% and 100% video parts (see above) - white or gray (min. 50%) pixels at the edges of the image (left, right, top and bottom). User manual MIVD 1218 To perform the calibrations: 1 Turn the control wheel to display the Calibration menu. ***MAIN MENU**** Calibration 2 Click the control wheel to enter the Calibration menu. 3 Turn the control wheel to select the calibration you wish to perform. 4 For the automatic calibrations: Click the control wheel to perform the calibration. During the calibration, the progress bar in the on- screen display is filled out. After successful calibration, the on-screen display shows the word "Successfully". After unsuccessful calibration, the on-screen display shows the word “Failed”. Please refer to chapter 5 : Troubleshooting for more information. 5 For manual calibrations: a) Click the control wheel to enter the menu. b) Turn the control wheel to change the contrast or brightness value. c) Click the control wheel to confirm the change of the value. 6 After calibration, click and hold the control wheel for a few seconds to exit the Calibration menu. The different calibration functions: Total Autoset ............This function performs the automatic detection of the number of pixels (horizontal and vertical) and all other calibration functions (described below) one after the other. This function takes a few minutes. Phase & level ...........Automatic calibration of the video sampling phase and the video levels (black and white) Auto level..................Automatic calibration of the video levels (black and white) Auto phase ...............Automatic calibration of the video sampling phase Manual phase...........Manual adjustment of the video sampling phase Manual black ............Manual adjustment of the video black level (brightness cal setting) Manual white ............Manual adjustment of the video white level (contrast cal setting) User manual MIVD 1218 Note: The calibration of the video levels determines the calibrated position or default setting of contrast and brightness. The black level calibration determines the brightness, the white level calibration determines the contrast. 3.5. Getting information The Information menu allows you to get a lot of information about the display and the connected signals. To read the information: 1 Turn the control wheel to display the Information menu. ***MAIN MENU**** Information 2 Click the control wheel to enter the menu. 3 Turn the control wheel to select one of the categories: General or Timing. 4 Click the control wheel to enter the selected information menu. 5 Turn the control whee...
