So, well. The adapter you bought is meant to “extract” the VGA signal from a DVI-A connector. DVI-A is a true analog (hence “A”) VGA signal. That means it doesn’t convert anything but the connector type. So, when you employ it in reverse, it converts to DVI-A. Most displays do not support DVI-A. If they employ proper (DVI-D) connectors, a DVI-A plug will not ...
VGA is an analog signal, and DVI-D is a digital one. This means your convertor is not converting to the 4 digital pins, and the videocard or monitor is primarily checking for signals on those 4 pins, and no video is going through it. I've had it myself on a monitor. Your convertor is likely VGA to DVI-I
Basic VGA cables are comprised of fifteen wires and support resolutions of 640x480 or less. If you use a cable like this on a modern computer with a higher resolution, it will probably display some kind of picture but with significant ghosting. High-resolution VGA cables (sometimes called SVGA, Coax VGA, premium VGA, etc.) are comprised of three coaxial ...

There is no definition of SVGA or VGA cable. Technically it is just D-Sub and it handles are possible resolutions although it may cause problems like blurriness in case of big resolutions like fullHD. The cable may be more shielded (thicker) though and naming it SVGA may suggest that... Usually thicker cables are better and there is lesses risk of artifacts ...
You may try a shorter cable. It seems that the integrated graphic card does not send powerful-enough signal. I had similar problem with 5 metres long cable - once connected to integrated notebook D-Sub port, display flickered; once connected to PC (with graphic card, over DVI-VGA converter), everything worked. Same setting but with shorter cable (2 ...
A passive adapter doesn't change the signal, it just connects the right pins on one connector to the right pins on the other. It is for when the signal is already in the right form, you are just matching connector formats. An active adapter takes the input signal and converts it to another type of signal. To go between analog and digital requires an ...
With that many converts you are probably suffering power loss and that is why it does not work. Get a VGA to HDMI. Only use one adapter. You can get a Belkin VGA to HDMI for about $50 or you can go cheap and pick one up for about $15-$20. If it was me I would go the Belkin one for $50 or a well known brand.
