Ideapad 720S not able to display external 2K monitor at 2560x1600 @ 50Hz

Brand new 720S from Lenovo.

Fully updated Win10.

Fully updated Nvidia MX150 drivers.

Fully updated Intel drivers.


Because the 720S is using OPtimus, I'm unable to get the MX150 to display, so I have to use the Intel 620.

The best I can get is 30Hz at 2560x1600 with the Intel. Anything higher creates odd errors or a blank screen.


With other laptops using a GTX1050 GPU there are no problems.


Anyone know how to get the Intel refresh rate up to 50Hz?

Or better yet, is there a way to force the MX150 into controlling the resolution and refresh rate?
