Hi. I have got a Matrox G450 X4 MMS graphics card. It has 2x LFH-60 Connector. Usually it comes with LFH-60 to 2x DVI and LFH-60 to 2x VGA Adaptor cable but I only have got a DMS-59 to 2x DVI adaptor cable. (DMS-59 connector fits onto LFH-60 of the G450 but is missing one pin). I only get a blackscreen but the PC does indeed POST. I tried using this DMS-59 to DVI adapter connected to a DVI Monitor, also a DVI-VGA adaptor and also DVI-HDMI adapor.
