 The use of other timings may in fact damage such monitors and thus was usually avoided by software publishers.Third-party "multisync" CRT monitors were usually much more flexible, and in combination with "super EGA", VGA, and later SVGA graphics cards using extended modes, could display a much wider range of resolutions and refresh rates at wholly arbitrary sync frequencies and pixel clock rates (within a particular lower/upper range, depending on model, typically encompassing a range spanning CGA's 15.7 kHz to SVGA and XGA's 36 kHz at a minimum, and including the 18.4, 21.8, 24.8 and 31.5 kHz of MDA/Hercules, EGA, "25kHz medium resolution" (a standard popularised by several Japanese domestic-market computers) and VGA along the way), commonly reaching 640x400 to 720x480 (at 56 to 72 Hz), 752x410, 800x560 and 800x600 as standard or near-standard settings.For the most common VGA mode (640×480 "60 Hz" non-interlaced), the horizontal timings are
