T420S - Win 10 1067, external display is not connected


I have reinstalled my T420s with win 10 1067, it seems the machine can not display on my external monitor (using display port, or any connection).

when I set extended or duplicate displays it seems to have 2 displays (the lenovo and my Dell U2414h) but i see nothing on my Dell. Of course i triple verified the input on my Dell is the relevant display port and i am using the same display with the same connection to my T460s ! )


I can see in the device manger only the intel Graphics 3000 and there is PCI serial port which is not recognized.

I went over all the drivers in the support page and updated my device manger, including chipest and bios.


Still nothing helped. Any help will be appreciated.


And we're back...
