tu peut faire un cable hack comme indiqué dessous (desolé en anglais et pas tres clair ....)
If you're using an AVGA card, the only thing you need to worry about it where your R,G,B,Ground, and H/V sync will go in relation to both plugs. I used the following diagram for my cable splice.
VGA Pin # Monitor's wire harness
1 - Red - Red (1)
2 - Green - Green (2)
3 - Blue - Blue (3)
6 - Red Ground \
7 - Green Ground \
8 - Blue Ground +--- Black (4) -- Ground
10 - Ground /
13 - H Sync \____ White (5) -- Combined HV Sync
14 - V Sync /
Look very closely at the end of a computer monitor's 15 pin D-sub connector. You will see (starting in the upper left corner) sequential numbers going from left to right. These identify the pin # of the PC monitor's wiring, which I've identified above. Pins 5, 9, 11, 12, and 15 are not used in this splice, so dont worry about them. After you remove the cable from the old PC monitor, use a digital multimeter and starting with the #1 pin on the 15 pin D-sub, check wires at the end for continuity. Write each color wire down and what pin it is wired to. Once you have everything mapped out, solder your monitor's video cable to each of the corrisponding wires.
Make sense?
