Datasheet titled with the SFD064VT4 part number and ADV suffix, a 360 KB PDF. ADV probably stands for an advanced or extended spec, but the name gives no definition. It sits with VGA and INVT files for the same module. Expect mechanical drawings, connector assignments and electrical characteristics useful when replacing, mounting or powering the display. Revisions differ, so match the VT4 marking on the hardware rather than the similar VT2 part before relying on dimensions or pin data.
