Hey there, donjonson! 

 

Welcome to the Lenovo community group!

 

What type of cable do you use? Are you using this type of adapter USB-C to HDMI 2.0b Adapter http://accsmartfind.lenovo.com/products/4X90R61022?CID=ww:lenovosocial:20x9m6? If not, we recommend using this USB-C to HDMI adapter and check it again. 

 

Regards!

I am using the full size hdmi port on the laptop with an hdmi cable.
Can you reccomend a usb c hub that will support cat-5 and external 4k monitor?

We saw a USB-C hub in Amazon with good reviews, however, we personally haven't tested it yet.

so apparently the hdmi port on the yoga 730 cannot output any higher than 2560x1440

after purchasing a usb-c dock with an hdmi out (among other ports) I was able to drive the full 3440x1440 external monitor
