T560 on Pro Dock with 2 external monitors - blurry screen via VGA

2016-08-19, 13:56 PM

So, I have a following HW:

- ThinkPad T560

- ThinkPad Pro Dock 90W (40A10090EU)

- 2 external identical monitors (Eizo EV2436W)

 

Currently I am trying to use 3 screens:

1. internal on the laptop with resolution 1920x1080 @ 60Hz

2. external monitor connected to Pro Dock using DisplayPort with resolution 1920x1200 @ 60Hz

3. external monitor connected to Pro Dock using VGA with resolution 1920x1200 @ 60Hz

 

Internal display is okay, unfortunately for the external displays, I can set 1920x1200 only on 1 external monitor by default & 1920x1080 for the other one. When I use tool from Intel for managing the displays, I am able to set the custom resolution for the 2nd monitor to 1920x1200 but the image is blurry (I bet you to come and try to look at it at for 5 minutes). Based on the dock specification I can use only DP+VGA or DVI+VGA and both setups should be able to support 1920x1200 on both monitors.

 

What I tried:

- turning everything on and off :)

- update of graphics card driver

- update of dock driver

- DVI+VGA and DP+VGA (blurry image on VGA)

- DVI+DP (not working at all)

 

I bought Pro Dock based on the documentation here, so I expected 2 external monitors at 1920x1200, but I can achieve that only when the second monitor is not connected to dock, but directly to laptop using MiniDisplayPort-DisplayPort cable, but that ruins the whole purpose of having a dock.

 

Any help highly appreciated!
