The question of how to make a vga tulip adapter is more popular today than ever. Many people like the idea of connecting a TV to a computer. And a lot of speculation is being made on this.
It is necessary
Internet very old TV-out over d-sub video card, d-sub m connector, rca connector, 75 ohm coaxial cable, soldering supplies
Instructions
Step 1
On the internet you will find a ready-made tulip vga connector, but unfortunately, even if you buy it, it will not work. To transfer a composite signal from a computer to a TV, the video card must support this type of signal standard. Until 2000, they produced video cards with support for tv-out over d-sub. That is, you could really connect a TV to such a video card through the vga tulip adapter. However, after 2000, the signal transmission standard was changed, and video cards stopped transmitting the composite signal. Thus, if you make a vga tulip adapter or buy a ready-made one and try to use it on a modern video card, the adapter will not work under any circumstances.
Step 2
If you still need to output the signal from the vga output of a modern video card through the composite input to the TV (yellow tulip video), then the only way to do this is to purchase a special converter device. It performs signal transcoding between different standards. The cost of this converter varies from $ 10 to $ 20. This is a rather complex device, so only a professional can assemble it on their own.
Step 3
If you are the lucky owner of an ancient video card (released before 2000) that supports tv-out over d-sub, for example, from Matrox, you can try to make a vga tulip adapter yourself. To do this, you need a wiring diagram for the rca and d-sub connectors or "pinout".
Step 4
Prepare vga connectors and cinch for soldering. Open the protective case, apply flux to the desired pads according to the pinout. Take a piece of cable of the required length, strip the ends, tin them.
Step 5
Be sure to slide the connector housings onto the cable before soldering it to the connectors. Solder the inner core of the cable to the center pad of the cinch connector and pin number 3 of the vga connector. Solder the shield conductor of the cable (braid) to the other pin of the cinch connector and to pin number 8 of the vga connector on the other side of the cable.
Step 6
Gather the connectors on both ends of the cable. The adapter is ready. You can try connecting your TV to your computer.
