My guess is that this is a problem with the cable instead of the monitor. Most cables I've seen don't use 75 Ohm coax cable for the monochrome video output. This impedance mismatch between the ST's video output and the monitor's input results in the "shadows" in the horizontal direction. This effect is more noticable in the high rez mode since the scan rate (I can't remember the exact number) is much higher that the medium and low rez modes. In addition, the common practice of connecting the monochrome signal to the Red, Blue and Green video inputs of a multisync monitors adds to the mismatch.
