Nds surgical imaging Radiance Series, Manual

14 

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 NDS 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.
