An electromagnetic gasket comprises a substantially rectangular sheet having a plurality of resilient fingers on an outer peripheral. The fingers are bent outward and at least four resilient prongs are bent inward to form a passageway that is sized and dimensioned to receive an HDMI connector. When the HDMI connector is inserted through the passageway, the resilient prongs are adapted to urge against top, bottom, and two side surfaces of the shell of the HDMI connector in such a manner to prevent the gasket from disengaging from the HDMI connector. The plurality of resilient fingers extend outward and beyond the top, bottom, and two side surfaces of the shell of the HDMI connector and are adapted to urge against a surface of a faceplate. The plurality of fingers and prongs of the gasket provide a direct grounding path between surfaces of the shell of the HDMI connector and surface of the faceplate.
