Lenovo X1 Type 3460 - no signal from mini display port to display port or hdmi

Hi all

 

I have just bought a new Lenovo X1 Carbon Touch Typ 3460 notebook and I'm having the following technial issues:

- Lenovo adapter minidp to VGA works fine

- Lenovo adapter minidp to HDMI or DP does not work. The Intel HD graphic 4000 graphic card recognizes the monitor (DELL u2913wm / U2412M) but no signal is sent to them

- Lenovo cable minidp to DP: no signal (the same issue that I have with the minidp to HDMI)

 

OS: Windows 8.1 Pro (new set-up with all updates)

Driver version of the graphic card: 10.18.10.3958 (automatically installed by windows 8.1 update)

 

If I do the same tests with the same monitors and adapters / cable with my Lenovo X1 2047, they all work fine!

The driver version of the Intel HD 4400 graphic card on this X1 is 10.18.10.3304. 

 

Any input is welcome!

Hi Carlosros,

 

Welcome to Lenovo Community!

 

As per the query we understood that you are facing issue with mini Display port on your ThinkPad X1 Carbon.

 

Please uninstall the current Windows updated graphic driver from the system and download the latest driver from Lenovo support site and install it, sometime compatible drivers will not support for the external monitor.

 

INTEL HD GRAPHICS DRIVER FOR WINDOWS 8.1 (32-BIT)

INTEL HD GRAPHICS DRIVER FOR WINDOWS 8.1 (64-BIT)

 

Hope this helps.

 

Best regards,

Hemanth Kumar

Hi Hemanth

 

Thank you very much for your quick feedback.

I've just installed the drivers unfortunately with NO success.

 

Important information. Both monitors go to "energy save mode" as soon as they get connected with the X1 over the mini display port to HDMI or DP (something I've just realized right now). Could it be the card do not send "enough signal power" over the port?

 

Best regards

Carlos
