Re: Yoga 920 USB C to HDMI not working

2018-02-26, 8:50 AM

I updated the USB-C driver through both the Lenovo Vantage, and manually. I've even reset the port as well by holding the power button for 8 seconds, then trying to install again. Latest Bios, no other critical Lenovo updates.

The update seems to pass flawlessly, yet when I plug my cable into a monitor, the entire computer flashes the screen on and off, seems to freeze up, and operate one frame at a time. It only secedes when I unplug the cable and the laptop snaps back to life.

 

Here's the cable I have, it seems like it should work fine: https://www.amazon.com/Kimwood-Thunderbolt-Compatible-Macbook-Chromebook/dp/B073QLDFJS/ref=sr_1_3?s=electronics&ie=UTF8&qid=1519633948&sr=1-3&keywords=kimwood+usb-c+to+hdmi

It never worked once pre-update.

 

Is the driver supposed to install a device in the device manager? Under USB devices, I see the UCSI USB Connector Manager, and seemingly no other USB-C controllers. Would love if someone who's is working could confirm they have another USB-C device, and what it is called.

 

I have one 'unknown device' in my manager, and cannot determine whether it is related to my problem or not.

Viewing its properties, its Device Instance Path is 'ROOT\RDPBUS\0000' , and its Device Stack includes '\Driver\rdpbus' and most worrying, '\Driver\PnpManager' (Plug and Play manager).

 

I'm doing the first recommendation at this point and buying this cable instead in case the cable is just somehow not compatible or defective: https://smile.amazon.com/gp/product/B075V5JK36/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

It will get here Wednesday Feb 28th and I will update this post then.

 

I know this is a very complex issue as I've explained it, but would appreciate any help. I've had the laptop for 3 months and haven't been able to enjoy it thoroughly at all yet.

Thanks for sharing, I'm just overly picky and wewnt for the stylish cable over the obvious common and compatible choices.

 

If my second cable doesn't work, I'll fall back to your suggestions in troubleshooting, thanks for taking the time to share your experience with me!

UPDATE: A new cable solved my issue

This one works: https://smile.amazon.com/gp/product/B075V5JK36/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Although it kinda wiggles in the USB-C port, and the HDMI plug is very long, but I was drawn to the woven cable.

 

This cable does not work, do NOT buy it: https://www.amazon.com/Kimwood-Thunderbolt-Compatible-Macbook-Chromebook/dp/B073QLDFJS/ref=sr_1_3?s=...

 

It seems at this point, that if you updated the USB-C port Firmware with Lenovo's driver update, the main problem seems to be cable compatibility if you're still having issues.

Thanks for updating. I think this adapter should work as well since it's the same company and look very similar.

I was hesitant to buy it, but now I'll try it.
