The second monitor does not want to work from the built-in video card

Hi guys.
I have a gtx 750ti graphics card, the main monitor is working properly on VGA, the second monitor connected to the built-in intel hd graphics 4600 also on VGA, but the monitor does not work. There are no HDMI ports in monitors, it does not work through DVI either.
MAC OS Sierra 10.12.6
Its config attached

There is no support for VGA at all, Apple just do not use it.
