W540 UltraDock 170W DisplayPort Issues

2018-05-07, 12:54 PM

Hello,

 

I have an issue where the DisplayPorts will only out put a max resolution of 2560x1440. 

 

I have two Dell U2718Q external monitors that runs a 4k resolution (3840x2160@60Hz).

With the laptop LCD closed down, if I plug in one of the monitor using the UltraDock 170W 's DisplayPort, my max resolution is 3840x2160. However, if I connect the 2nd monitor using the seconf DisplayPort of the UltraDock, I am limited to 2560x1440 on both external monitors.

 

I've tried updating all the firmwares (Intel Chipset and UltraDock) on the W540 to the latest, updated the bios.

 

Can someone from Lenovo confirm if the UltraDock 170W with a W540 supports 2 x 3840x2160@60Hz on the dock DisplayPorts?

 

Many thanks,
