Re: Yoga 720 dock compatibility

2017-11-03, 0:34 AM

I've only done it with the dock, as that's the only device I have for DP output.

Re: Yoga 720 dock compatibility

2017-11-12, 15:39 PM

snake, can you please advise whether you believe it is possible to extend/project to two external screens/monitors from my (new) lenovo yoga 720 (13.3") and, if so, what exact adapters/docking station would I need?  the insignia usb-c to hdmi adapters didn't work (confirmed by lenovo tech support today because those don't support "out mode"???).  tech support couldn't tell me the specs for a docking station, but said i'd need one.  frustrating.  thanks.

I'm guessing that tech meant "alt mode".

 

I imagine the Lenovo Thunderbolt3 dock would work for you the same that it works for me on the 15" Yoga 720. 

 

The Lenovo USB-C non-TB3 dock is a little cheaper but might max out at dual 1080p or something. The dual QHD I'm using might be close to the limit for external displays on the TB3 dock. I know dual 4K/UHD doesn't work at 60hz.

thanks, snake. So I should plug one of my two "monitors" (both monitors are actually 24" Vizio LED - 1080p - Smart - HDTVs) via HDMI cable into the only HDMI port on the TB3 dock. Then I should plug the HDMI cable from the second monitor into which port on either the dock or my Yoga 720 (and using what type of adapter for whichever port)?

Re: Yoga 720 dock compatibility

2017-11-25, 20:46 PM

Just bought a 720 15.6" with Intel Graphics card. I found that my Plugable USB3.0 (UD-3900) works fine. Plug it into the USB-C (Alt Monitor) port. Windows 10 will go throught some setup for the docking station and attached USB accessories. I connected fine with the DVI to ViewSonic 22" 1080p HD. 

 

NOTE: The docking station setup was automatic and shows the docking station as a display adapter.

 

Don't have a HMDI cable I can connect my 2nd monitor. So I have to wait. Maybe two monitors and the 720 screen is a little much for my development needs.

 

Hope this helps.

 

Dave

Hi Prabhansh!

Mayby you can solve my problem?

I recently purchased a Yoga 720-13IKB together with an USB-C dock for HDMI and power delivery and I've also bought a "solo" USB-C - HDMI cable.

 

Sadly i'm unable to get a video signal. Windows tells me that the device maybe doesn't support Displayport alternate mode, which is apparently mandatory for HDMI over USB-C.

 

Does the Yoga support Displayport alternate mode at all or is there an other way to connect the device to a HDMI equipped tv?

I have also downloaded and installed the latest official Thundebolt Driver (Thunderbolt Driver for Windows 10 (64-bit) - Yoga 720-13IKB (Type 80X6), V16.2.55.1, 2017/03/13) - with the exact same negative result... and exact the same result with all updated drivers and bios :smileysad:

I would use the HDMI on the dock and a DP-to-HDMI adapter plugged into a DP port on the dock as well.

Pretty sure that your TB3 USB-C port supports DP alt mode. Not sure about the other USB-C port.

 

're only trying to hook up 1 external display? 1080p @ 60hz? 

 

Does your adapter say anything about alt mode in its description? Here is one that does for $14: https://www.amazon.com/CableCreation-Adapter-Thunderbolt-Compatible-Chromebook/dp/B01MQD3I2Z/ref=sr_1_2_sspa?ie=UTF8&qid=1511979661&sr=8-2-spons&keywords=usb-c+hdmi+alta&psc=1

Windows keeps tell me this error message that Windows shows constantly:

"The display connection may be a monitor
Make sure that the DisplayPort device you are connecting to is supported by your computer. Select this message for more information. "

BTW... I have tried approx. 6 different brands/models of USB-C HDMI from different shops here in my town... with exactly same negative result... and different brand new TV models that supports HDMI connection to computers.

NOTE:
This are the specs for my Lenovo Yoga 720:

Re: Yoga 720 dock compatibility

2017-12-14, 22:05 PM

Hi. I own a Yoga 720 and called Lenovo and they recommended that I purchased the ThinkPad USB-C Dock. They said it was compatiable. I see that yyzlhr is saying it worked for them. However, I've not had success. I've updated drivers and have attempted to update the firmware, but it's saying the "DP" is not detected. I've called Lenovo support and they say they think that this dock (which says "ThinkPad" on it) isn't capatible with my Yoga 720 because the 720 is technically an "Idea Pad."

 

Can someone confirm if this dock works?

If so, can someone guide me or point me to a resource that shows me step by step on how to set this up?

 

Thank you.
