i am searching for a new desktop monitor with uhd resolution and found this info in a review about the BenQ EL2870U.
Interlace pattern artifacts https://pcmonitors.info/reviews/benq-el2870u/
On some monitors 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. Alternatively, static interlace patterns may be seen with some shades appearing as faint horizontal bands of a slightly lighter and slightly darker version of the intended shade.
We did not observe any static interlace pattern artifacts, although we did observe some dynamic interlacing patterns in places. When scanning the image or observing motion on the screen, some shades appeared to break up into slightly darker and lighter variants of the intended shade as described in the first paragraph. This was most obvious when moving your head backwards or forwards whilst looking at the monitor. The interlacing was very fine and faint so won’t bother most users, but some could find them bothersome.
could this be a problem for me? i´m very sensitive to PWM and maybe FRC.
