Most modern video cards only support 1 analog out. VGA = analog. Double check your ports on the video card that it has four small holes next to the blade port on the video card. That will tell you it's analog and can support VGA. If there is only a blade port and no 4 small holes surrounding it, it does not support VGA, you cannot mash a DVI to VGA converter on it to swap it to analog (there is no analog clock on that port).

Check this web page out and see how there are two different DVI connectors. Ones with 4 pins around the blade (VGA supported), and ones without 4 pins around the blade (no VGA).

Also, HDMI is digital ONLY, again there is no support for analog (VGA) on that port. You can buy adapters to go from HDMI to DVI to VGA, but it will not work. The first two are digital signals(HDMI and DVI), and the last is an analog signal (VGA). Those adapters only change the physical look of the port, they do not convert signal types. VGA is an older style of signal to monitors and is being phased out. Most video cards will only support 1 analog signal, and a few are already not supporting any VGA signalling.

With the computer saying there is no monitor connected, that would be my first guess.

I also have another DVI to VGA converter with 24+5 pins which i got with my old video card . So, for test i broke 4 blades to make it look like DVI-D , and then when connecting with this converter my pc responded and it recognized my 2nd monitor ,now my multiple display is enable BUT THE PROBLEM IS that my 2nd monitor is black but when i move the cursor beyond the 1st monitor it goes to the 2nd but no display ,i also checked the powercable and display cable and are connected
