● The type of video board or connecting cable used may not allow for correct displays adjustment of Horizontal Position, 
Vertical Position, Horizontal Clock and Clock Phase. 
● The unit differentiates the signal modes according to the horizontal and vertical frequencies and the horizontal and 
vertical sync signal polarities. Note that different signals having all these elements alike may be handled as the same 
signal. 
● Displaying images with more than 768 lines of vertical resolution a Full display (compressed display) can result in the 
interpolation of stripes.
