Selecting a secondary input displays a small image of the data connected to secondary source in the upper right corner of the display. Secondary Image Size Control The size of the secondary image is controlled by pressing ◄ or ► buttons. Pressing the ► button will cycle through: Small = ~ 25% of Primary height in upper right corner. Medium = ~ 40% of Primary height in upper right corner. Half = Primary and Secondary appear at equal height side by side, secondary on the right side. Expanded = Primary and Secondary are equal height side by side, but expanded somewhat. None = No secondary image displayed. The images at the bottom of the page illustrate the above sequence. Pressing the ◄ button will cycle through the above sizes in reverse order. Pressing the SCROLL / SWAP button will exchange the primary and secondary inputs, and exchange their respective locations on the display. Pressing the button a second time will restore the inputs to their original primary/secondary status. It is not necessary for both images to be displayed in order to swap primary and secondary images. The swap operation is different when the primary input is: S-Video or Composite and the secondary input is: SD-SDI, SD-RGBS or SD-YPbPr. In this case, pressing the SWAP button will cause the secondary image to be displayed full size, the primary image will not be displayed. Pressing the SWAP button again will restore the primary and secondary images to their original sizes and positions. Secondary image size and image swapping may also be controlled via the GPIO port.

Troubleshooting Section Image Size is Very Large for the Screen If the computer data does not appear to be the correct format, then SmartSync must be run. To run SmartSync, press the Menu button. Select the Setup menu. Press SCROLL to highlight SmartSync, then press the ► button. SmartSync will run and size the image properly. Ghosting in Characters Ghosting in characters is usually attributed to reflections in the video cable or source. Use a high quality coaxial cable and, if possible, lower the vertical refresh rate. Lower scan rates can help eliminate reflections. Unlike a CRT a flat-panel will not flicker at lower refresh rates (60 Hz is optimal) and data update will be the same at all refresh rates. Text is Too Small Since the monitor accepts and displays computer data with a higher resolution than the display’s native resolution, this may produce small text. In the Menu check the Display Mode tab. Verify that the computer data resolution does not exceed the Native Resolution specification shown on page 19.

Character Jitter If text characters seem to be “shaky” or bold, then Sharpness, Frequency and / or Phase may require adjusting. See: Setting Frequency, Phase and Sharpness below. Character Noise and Vertical Distortion The Frequency adjustment expands or contracts the horizontal size of the displayed image. The displayed image may be too wide or too narrow and vertical banding and pixel jitter may appear in grays and light colors. Adjust the Frequency until the image just fits the screen. Horizontal position adjustment can be used to verify that Frequency is set correctly. Line up the image on the left edge of the screen and then shift by one “click” to the right. The image should have one column off the screen on the right side if the Frequency is set correctly. Black Screen Power the display Off and On. If the KARL STORZ logo appears then the display is working properly. Check if the power management feature (DPMS) is enabled. An “Out of Range” message appears in the upper left hand corner when an input source is out of the display’s resolution range. A “Searching” message appears in the lower right hand corner when the video source is not present. Setting Frequency, Phase and Sharpness Windows Users: Open a WordPad document and set the font to Arial 8. Press the enter key to move the cursor to the middle of the page. Hold the shift and + keys down to create a line of +s. If the + signs appear in groups of light or dark, then the Frequency is not correct. Press the MENU button to open the OSM, then SCROLL to the Frequency parameter. Press the ◄ or ► buttons to increase or decrease Frequency. There will be a point were all the + signs snap into focus and are the same intensity. Phase and Sharpness are subtle adjustments and are best set using a display calibration program. Keypad does not control the display If the OSM does not open when the INPUT, MENU or Brightness / Contrast buttons are pressed, then the display may be in Remote Mode. See page 7 for mode setting instructions. If the “MENU LOCKED” message appears, press and hold the MENU and SCROLL buttons until the MENU UNLOCKED message appears.
