Narrative:

Presentation of electronic chart information on aircraft display omitted the display of a '1' in '190' of the textual departure heading instructions. (Newark 7 departure; runway 22R.) after departure; ATC queried our actions and gave corrective instructions. It was later discovered that at other display zoom levels; the text was displayed correctly. The crew consulted only the text instructions and did not check them against the graphical representation on the chart. The crew briefed the SID and read the chart 3 times. A photograph was taken of the display error for evidence. The error was duplicated on other company aircraft. Gulfstream technical support was notified. Contact was made with new york TRACON after the flight and a photograph of the display error was e-mailed. Callback conversation with reporter revealed the following information: the captain advised that the error is in the display of the chart on the multi-function display in the efb mode. In the FMS mode there is no display of the two pertinent headings and; thus; the departure is flown in the heading select mode. He believes the dropped numeral only occurred on the third 'zoom in' from the default display mode. He reiterated the fault was reproducible in other company aircraft. Reporter commented the flight crew didn't review the graphic display because; as a 'heading' type of departure there was no 'route' to follow. Had they checked the graphic the error might have been caught.
