The type of video board or connecting cable used may not allow for correct displays Set H.POSITION, V.POSITION, CLOCK and PHASE.

When a signal has been input with a vertical frequency of greater than 60Hz, it may not be possible to obtain smooth display of animated images in some cases.

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.

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.
