The monitor may fail to display an animation image correctly when a signal having a vertical frequency of 60 Hz 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. Take care that especially Full displays with a resolution of 1280 x 1024 can result in a completely black or white screen, depending on the pattern. 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. Horizontal timing Horizontal frequency 24 kHz to 52 kHz Horizontal frequency 52 kHz to 80 kHz Vertical timing Front porch Sync width Back porch Blanking width 0.1 µs or more 1.0-3.8 µs 1.2 µs or more 3.5 µs or more 0.1 µs or more 0.8-3.0 µs 1.1 µs or more 2.3 µs or more 9 µs or more 100 µs or more 400 µs or more 450 µs or more 27
