This problem normally occurs only with RGsB Signals if you have long coaxial
cables, EMI noisy environment, high current power cables nearby or glitches from
old graphic cards.
For Video Signals with HS< app. 20kHz, try to select 15kHz Glitch Filter to ON in
Image Menu (Refer to page 32)
For Video Signals with HS> app. 20kHz, try to deselect Threshold Checking (OFF)
in Image Menu (Refer to page 32)
