So, seems I have figured out the issue (at least on my Lenovo T460s) and I think it lies with the Intel chip internal GPU.

If you use display port and HDMI-->Display Port adapter it won't work. The Intel chip doesn't seem to support two DP connections at a time. But you can connect Dp & HDMI-->DVI at the same time (or VGA for that matter) & Internal display. So max is 3 displays but they need to be different techs.

I can't confirm this for other laptops without external graphics cards since i don't have any more.
