I have used the D6000 dock for quite a few years and the problem only started today.

1 monitor works like it should.
2nd monitor on the displayport is recognized as "no monitor" and set at 640x480 without options to increase resolution.


Troubleshooting done:
- Installed the latest drivers version 11.2.3146.0, A05
- Tested the second monitor by connecting this display to my PC directly -> Monitor works perfectly fine
- Connected the D6000 to 3 different PCs/laptops -> all face the same issue with low res on the 2nd monitor
- connecting the 2nd monitor to a different displayport doesnt help either

First, the driver version you have installed may be the latest provided by Dell for the docking station, but it is not the latest from DisplayLink directly (which is 11.3 M0). If you have not already done so, please try using the latest driver --> https://www.synaptics.com/products/d...nloads/windows

The behavior you describe sounds like there may be an issue with the EDID process --> https://en.wikipedia.org/wiki/Extend...ification_Data which is why the display is only operating at 640x480.

A few questions:

1. What is the brand and specific model number of the affected display?

For example, 'Dell U2415'

2. If you replace the current video cable with a different one, does the behavior change?

3. Do you have a different model display you can test with temporarily? That will help determine if the behavior is specific to the display or the dock.

it was the cable... a displayport to DVI cable. Guess the signal processing chip was fried for some reason.

Thanks for suggestions rboerner!
