T560 with Thinkpad pro dock + 2 ext monitors display port not working

2016-11-04, 10:18 AM

T560
Thinkpad pro dock 40A1
2 x BENQ GL2450
using now 1 x VGA (old blue crappy monitor output)
1 x DVI output.
i want to stop using RGA out and use the display port, have
HDMI cable and display port adaptor.
problem is monitor never show up
no signal from display port. (according to msg on monitor)
using T560 as 3rd screen
according to dock info all 3 display outputs from dock should work simultaneously..
well it doesnt.. have upgraded everything! bios, dock software.. u name it..
how can i make this work? monitor is just a blur with VGA signal...
res is set to 1920x1080 but its not as clear as the DVI with same res setting.
i cant seem to make any montitor come to live on the display port....
starting to think it may be defective....

Hoping for an easy fix... tried to check arnd first but did not find an exact match to my problem.
