Interlace pattern artifacts
On some monitors, particularly but not exclusively those with high refresh rates, interlace patterns can be seen during certain transitions. We refer to these as ‘interlace pattern artifacts’ but some users refer to them as ‘inversion artifacts’ and others as ‘scan lines’. They may appear as an interference pattern or mesh or interlaced lines which break up a given shade into a darker and lighter version of what is intended. They often catch the eye due to their dynamic nature, on models where they manifest themselves in this way. We did not observe any such ‘interlace pattern artifacts’ on this model.

Some models display static interlace patterns, not linked to motion and observed when the monitor is simply displaying a static image as well. Some shades may appear as faint horizontal bands of a slightly lighter and slightly darker version of the intended shade. We did observe static interlace patterns on this model, with some light and medium blue, yellow and orange shades in particular showing this. The horizontal bands were reasonably faint and not everyone would notice or find them bothersome. Curiously, if you reduced the refresh rate to 50Hz they became even more faint. Increasing the refresh rate much beyond 60Hz (refer to a note on ‘overclocking’ in the next section) made these extremely obvious.
