Re: Yoga 920 USB C to HDMI not working

2018-01-01, 22:51 PM

I have a Lenovo USB-C travel adapter (which has HDMI, VGA, ethernet and USB 3.0 port on it). I had exactly same problem with everyone else (HDMI not working after Fall Creator's update).. I can report that "connecting the USB-C device with TV connected and turned on (and switched to that HDMI input) before booting-up" trick works. Tried twice in two different instances, and each time, it worked flawlessly. I am happy that it works, but this is definitely not ideal.

Re: Yoga 920 USB C to HDMI not working

Since I cannot wait for a fix, I'm looking for an alternative solution without USB-C.

 

Is there someone who has tried an "USB 3.0 adapter"?

 

For example this one:

https://www3.lenovo.com/us/en/accessories-and-monitors/cables-and-adapters/adapters/CABLE-BO-USB3-0-to-VGA-HDMI-Adapter/p/4X90H20061

 

Or does someone use a single USB-3.0 to HDMI or a single USB-3.0 to VGA adapter?

@Dengee  I took my 920 in to the Best Buy store where I bought it and worked with their Geek Squad.  They tried everything they had in the way of video adaptersincluding  the USB-C and USB 3.0.  It did not change the results for my machine.  Even if it did work, they figured it would send a poor resolution signal to the display. You might want to try it and if it doesn't work send it back for a refund.  

 

Last I heard from @LenovoSupport (last Friday) on Twitter, they have no resolution to this problem at this time and don't know when they will....

FOUND:   SOLUTION WITH USB-A 3.x PORT ADAPTER:  j5 jud380

 

I finally tried an adapter for the USB 3.0 - the j5 jud380.   It has 1  hdmi and 1 vga port which you can use to extend the laptop screen to both monitors (dual display)  and it works consistently (plug and play after installing adpater drivers).      The adapter also has 1 ethernet and 2 additional USB 3.0 ports.  I didn't find the screen resolution to suffer to my eyes and though 3.0 is slower than USB-c it isn't an issue for my work.  Device quality and size compare favorably with the others I tried (e.g. Juiced).  I got it for $70 at Best Buy. jud380 adapter details are here.  

I'm not super happy that I had to buy multiple adapters to figure this out and ultimately now on a slower port, but it works for my needs ... hope this helps for others.

 

P.S. ... one mildly annoying thing about the J5 adapter is that the vga port doesn't have any built-in nuts for screws on the VGA plug.  I haven't use it much yet and so far it hasn't disconnected, but you won't want to be moving your machine around once you get it connected via vga.

Have you seen this thread? https://communities.intel.com/message/514293#514293

Somebody found an adapter which should work - can anybody confirm this?

Check post 99 by goredsox from 12/14/17. He is the one that posted on Intel's site. Current status shows "unanswered". goredsox did show in that report methods to get HDMI to work and scenarios where it will not work. So no, it is not verified.

Re: Yoga 920 USB C to HDMI not working

Using information from this thread, I do have plug and play that works from booting up with adapter plugged in or not plugged in, and works plugging in to a machine that has been operating for an hour or more.  What is still lacking is when the machine goes to sleep and you wake it up.  It works sometimes but not always.  I learned this by resetting the machine to factory defaults and then updating drivers a step at a time.  Once I found what looked like it worked in most scenarios, I repeated the process and verified it.  Therefore, it is a driver problem.  Yes, Intel does have a driver that does work for other makes, but Lenovo always has their own version.  Intel does not support installation of that driver on a Lenovo machine.  Therefore, it is Lenovo's problem.  Based on the Lenovo Moderator's participation in this thread, they are not interested.  Responses on Twitter from @LenovoSupport continually say they don't have a solution but never really say they are working on it.

 

The best chance you have to get this working is by using the following drivers and not letting automatic updates to happen, or let them  happen and revert these drivers as follows:

     Display Adapter 6/16/17 22.20.16.4708

     Intel USB 3.0 Host Ctlr 4/27/17 10.0.15063.296

     Windows 10 10.0.15063 ver 1703

(Covered in post 138)

 

That should work for most people’s needs but it’s still a cheat that does not live up to advertised specifications.  How can I go in to an Internet Service Provider to make a presentation with a computer that kind of works, most of the time, maybe? 

 

We still need to keep pressure on Lenovo to get it fixed to operate at their own specifications.  You could try Tweeting to @LenovoSupport and see what they respond with.  If you do, post their response here so we all can compare notes, watch for inconsistent respones and keep the pressure on for a real solution.

STAY TUNED FOR MORE....

 

I thrilled to report that I already received a reply from a Lenovo VP in response to an email I sent to him today:

 

"I know the teams are working to get a driver update to fix the issue. I will have the team post on the forum."
