ThinkPad P70 Workstation Dock with HDMI monitor blinks intermittently

2016-02-03, 0:48 AM

This is all brand new kit.  The P70 works perfectly and so does the external monitor when I plug the HDMI cable into the HDMI port on the P70.  However, if I connect the HDMI cable to the HDMI port on the Dock and then dock the P70, the external monitor blinks (black screen) every 5 to 30 seconds or so.  The blink is about 0.5  to 1 second in duration.  I have found posts from 2013 regarding a similar problem on the Thinkpad Ultra Dock which was resolved with a firmware update. Is there a resolution to this issue or a firmware update available?  If not I will have to return the dock as there is no point in having it if I cannot use a multiple monitor configuration when docked.

 

Any help gratefully received.

 

Andy

Follow up:  I contacted Lenovo support.  The tech I spoke to was superb.  He remotely connected to my machine and reinstalled all the video drivers ensuring I had the latest of everything.  All works perfectly now.  All smiles here.
