Im having problems with an external monitor. Its stuck at 4k@30Hz, even though my hardware should be able to produce 4k@60Hz.
My setup is 7th gen X1 carbon (20QE001FMX) and USB-C Gen 2 Dock https://support.lenovo.com/us/en/solutions/acc500106 (40AS) and Samsung U28R55.
X1 is connected to the dock and dock to monitor with HDMI 2.0. Ive gone through all the solutions online and Im out of ideas.
Is there something Im missing? HDMI cable is 2.0, monitor supports 4k@60Hz and has HDMI 2.0 port, dock supports one external monitor with 4k@60Hz.
Solved! Go to Solution.

Thanks for the reply,
Ive looked at that page many times, but never realized that. I just assumed that 1.2 will always support 4k @ 60Hz.
Any idea whats the easiest way to use a 4k@60Hz external monitor with X1? Thunderbolt to DP converter or something?

Have a look at this USB-C to DisplayPort Adapter:
Also have a look at these links:
It should provide enough info to get to a solution.
