Is the Intel HD Graphics 4000 graphics card a DisplayPort 1.2 graphics card with MST support and Dual Mode DP++ function?

I want to connect 2 external monitors to my Lenovo X1 Carbon laptop and therefore extend (NOT duplicate) my desktop to 3 displays: 1 internal laptop display + 2 external displays. I've attached my system information.

Any help is much appreciated. Thanks

The DisplayPort outputs of the 3rd generation Core processors with Intel HD Graphics 4000 support appear to be compliant with (only) DisplayPort specification 1.1a. Since MST support was not introduced until the DisplayPort 1.2 specification, I would conclude that, with only a single mDP connector, your laptop cannot support two external monitors. This jives with the User's Guide for the 1st gen Lenovo X1 Carbon laptop, which discusses only dual (internal + one external) monitor configurations.

 

Sorry,
