Which cable to use to connect tv with RGB input (female) to my computer which has serial 1 COM port (male)?

I just got a new computer built and it turns out my new computer is lacking a female RGB in the back that my old one had. It only has the serial 1 COM port and I guess I have to use that to connect to my monitor (which is my tv). I used to use a female/female RGB cable (guess thats the same thing as SVGA?) Help please.

Here are images to help explain...

This is the connector my PC/motherboard has:
