Yoga 920 USB C to HDMI not working

2017-11-13, 4:19 AM

Got a Lenovo Yoga 920 earlier this week. Plugged my USB C to HDMI adapter in and it worked for a few minutes and than stopped working.

It is now identifying as a USB 2.0 Billboard Device which I belive means it isn’t configuring Displayport Alternative Mode properly.

 

Here’s what I’ve tried:

Hitting Windows – P to change project mode.

Going into display settings and detect display.

Checking for Updating graphics driver, USB drivers, check for updates.

Using a different USB C to HDMI adapter, a different TV, and a different cable.

Booting to safe mode with no services running.

Any thoughts for re-configuring the driver?

All,

 

The new firmware is available on the web for all Yoga 920 systems and can be found through the following link;
https://support.lenovo.com/sk/en/downloads/ds501972

 

Currently this isn't available as an option to download from the Yoga 920 Glass download page, the web content team will be correcting this soon. In the mean time please use the above link and feel free to share the link in other communities you may be participating in.

 

Edit: The firmware is also available on the Yoga 920 Glass driver download page along with being distributed through Lenovo Vantage.  I'm marking this thread as solved in order that others might find the firmware links easier.

Satechi Type-C USB hub works! Best part is it can deliver power & display out. No more attaching power & display to diff ports.

Is it really?

I thought that the following products will work properly on YOGA 920.

 

"Lenovo USB C Travel Docking Station - USB Travel Hub with HDMI, VGA, USB 3.0 and RJ45 for Lenovo Yoga 920, Yoga 720 and Flex 5 Laptops (GX90M61235) " (by amazon.com)

I've the same problem. First I tried TOWABO. B072QL1WKC USB 3.1 Type-C to HDMI, it didnt work. I retutned it and bought TRENDnet USB-C to HDMI Adapter. That works on and off, still havent found something that works everytime I plug-in. If you find something that works consistently, please post.

There's a thread going on tried-and-tested USB-C devices for the 910. I would imagine similar results with these devices and the 920.

 

I, too, have the Trendnet, which has been consistent for me. DO NOTE, however, that HDMI handshaking is always a hit-or-miss issue. I've learned that the Trendnet has to be connected to the computer first. Otherwise, the TV won't handshake with it.

It's not a BIOS issue. It's typical HDMI handshaking. Your television expects to see a live, booted-up HDMI device on the other end of the cord the moment it's connected. If it doesn't see that, it cannot handshake with it, so some televisions will refuse to display whatever's connected to that port. You have to start over. 

 

It's a typical problem with home theater setups where someone might have a Cable Box connected to an audio-video receiver, which is connected to the television. If you don't power them up in a certain order, it doesn't work. It's different with different brands of equipment, but AV enthusiasts are very used to dealing with this. 

 

Connect the dongle to the laptop. Give it a few seconds to be recognized and configured by the computer, THEN connect it to the television. You may also run into the issue should the laptop go to sleep. The TV's copy-protection circuitry is no longer happy with the handshake, so it shuts off the port. It's not like the old days when you just connected a serial cable from a display and it worked the second you plugged it in. 

 

Be ready.. it's even WORSE with HDMI 2.0, which is needed for 4k.

BWT, case like this is the reason to stick with business series on laptops, like x1 (but no 4K). I have another laptop - x1 and all dongles works as they suppose to.

 

I was aslo disappointed when I found out that you cannot access to bios or boot options without a needle-like tool
