Yoga 730-13IKB - Thunderbolt 3 / USB to HDMI - not working - stopped working.

2019-07-06, 20:27 PM

Hi again, another issue.


I have a UNI multi dock - it was working fine - HDMI, SD card readers, USB. Suddenly one day it stopped. Display does not recognize signal, cannot change display mode with win+P - I can switch but cannot apply changes..

Intel software, windows settings - nowhere to see it.


I bought Microsoft USB-C to HDMI hoping the dock broke or something, but still the same. 


Installed all possible drivers again from lenovo, did windows update - still nothing. 


What else can I do?

Hi! Was there any changes or any updates installed before the issue arise? Just to make sure that all the drivers and firmware are up to date, run the update from the Lenovo Vantage app. Install all available updates then restart the computer. If the issue persist, run the hardware test from the same app to check for hardware failure.
