[[Dot pitch]] defines the maximum resolution of the display, assuming delta-gun CRTs. In these, as the scanned resolution approaches the dot pitch resolution, [[moiré]] appears, as the detail being displayed is finer than what the shadow mask can render.<ref>{{cite web |url=http://www.displaymate.com/moire.html |title= Moiré Interference Patterns |access-date=4 October 2006 |work=DisplayMate Technologies website}}</ref> Aperture grille monitors do not suffer from vertical moiré, however, because their phosphor stripes have no vertical detail. In smaller CRTs, these strips maintain position by themselves, but larger aperture-grille CRTs require one or two crosswise (horizontal) support strips; one for smaller CRTs, and two for larger ones. The support wires block electrons, causing the wires to be visible.<ref>{{cite web |url=http://computer.howstuffworks.com/question406.htm |title=What causes the faint horizontal lines on my monitor? |access-date=4 October 2009 |work=HowStuffWorks|date=21 June 2000 }}</ref> In aperture grille CRTs, dot pitch is replaced by stripe pitch. Hitachi developed the Enhanced Dot Pitch (EDP) shadow mask, which uses oval holes instead of circular ones, with respective oval phosphor dots.<ref name="auto14"/> Moiré is reduced in shadow mask CRTs by arranging the holes in the shadow mask in a honeycomb-like pattern.<ref name="auto4"/>
