GTX 750 not recognizing HDMI second monitor with Win10

Hi, i'm usign a pc with these specs:
Intel Core i7-4790S (3.20 GHz)
8GB DDR3-1600MHz
Intel HD Graphics 4600
2GB NVIDIA GeForce GTX 750
5x USB 3.0, 2x USB 2.0
Card Reader 16-in-1
1x VGA, 1x HDMI
Gigabit LAN
Windows 10

The problem is that i can't use the HDMI to use a second monitor. (Extended view)
The main monitor is using the VGA port, the other is the same monitor as the first, but using the HDMI with a HDMI->VGA converter, because this monitor have only the VGA port.
The PC don't recognizes the monitor at all, neither video nor audio.
I've tried all the latest drivers for almost all, monitor, VGA, Chipset.
What am I doing wrong?
I don't know if i can post the pc model or manufacturer, if you need it i will write it.

Maybe nothing.

And let's HEAR more about the HDMI - > VGA

Because the 5 to 10 buck versions DO NOT WORK!

About the adapter

I've only found 50+ dollar adapters to work.

As a test connect a HDMI display to the HDMI port.
