The same VGA cable can be used with a variety of supported VGA resolutions, ranging from 320×400px @70 Hz, or 320×480px @60 Hz (12.6&nbsp;MHz of [[signal bandwidth]]) to 1280×1024px ([[SXGA]]) @85&nbsp;Hz (160&nbsp;MHz) and up to 2048×1536px ([[QXGA]]) @85&nbsp;Hz (388&nbsp;MHz).

There are no standards defining the quality required for each resolution, but higher-quality cables typically contain coaxial wiring and insulation that make them thicker.

While shorter VGA cables are less likely to introduce significant signal degradation,  good-quality cable should not suffer from signal [[crosstalk]] (whereby signals in one wire induce unwanted currents in adjacent wires) even at greater lengths.

[[Ghosting (television)|Ghosting]] occurs when impedance mismatches cause signals to be reflected.{{cn|date=May 2025}} A correctly impedance matched cable (75{{nbsp}}ohm) should prevent this, however, ghosting with long cables may be caused by equipment with incorrect signal termination or by passive cable splitters rather than the cables themselves.
