I am confused with VGA port, and the cables. Since the VGA resolution is "640 x 480" and there's a VGA, SVGA cables in market. Would I need a QXGA or WHUXGA ports to be able to display those resolutions to an external monitor? Or, are there only just cables called QXGA or WHUXGA that work with VGA port?

The same VGA port and the same VGA cable may be used for both VGA and its extensions such as SVGA, QXGA and others. The supported resolutions depend on the graphics card and the monitor. However, because VGA is an analog interface, the image quality may vary, and some cables may work better than others. Digital interfaces such as DVI, HDMI or DisplayPort offer generally better performance at high resolutions.
