PRODUCT SPECIFICATIONS (continued)
• The type of video board or connecting cable used may not allow for correct displays adjustment of
H.POSITION, V.POSITION, CLOCK and PHASE.
• The monitor may fail to display an animation image correctly when a signal having a vertical frequency
of 85Hz or higher is input to it.
• The monitor 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 512 lines of vertical resolution at Full diplay (compressed display) can
result in the interpolation of stripes.
• Use of this monitor with the input signal timings specified below is recommended. A predefined setting
may not be reproduced correctly with an extremely long front porch or back porch or with an extremely
short data display time.
