P70 new 4k Monitor won't do 60hz

2017-12-11, 17:30 PM

Hey folks,

 

I have a p70 with the M3000M and the 230w workstation dock.  I just picked up an LG 43UD79‑B over black Friday and it's working great.  

 

The only issue I'm having is I can't get it to do 4k at 60hz (which the monitor does.  Based on my research on the dock, it looks like DIsplay Port is my best (only?) bet.  Initially display port worked but wouldn't do 60hz.  Now it doesn't want to work at all.  I've been using the dock's HDMI and it works fine at 30hz.  My drivers are up to date according to Lenovo.

 

Any ideas?

 

Thanks much.
