Thank you Dengee. 

I should have been more clear in my latest post. I was referring to the model of the TB3 dock itself (not the Yoga).  I just wanted to be sure we were all talking about the same item. 

 

FYI: I ordered the equivalent US version of the Yoga 920, Model 80Y70066US (i7, 16GB, 1TB SSD)

 

Thanks again for your reply

Okay, I didn't notice that either...

Looked into the order receipt and it is called "40AC0135EU" - so it should be the same, since this is only the marketing product number. The real model number/type (which is also printed on the back) is just "40AC"...

Re: Yoga 920 and Thunderbolt Dock

I would like to raise the topic a bit again in the light of 01/04 update which has fixed the earlier issues with connecting external equipment with my 80Y7 Yoga 920 (i7-8550U).

 

1) As a result of the update, there are no more issues with external adapters or monitor cables: I have tested 4 different adapters or simply Display Port cable options successfully on my three UHD monitor setup. I am able to run them all as an extended desktop and [somewhat crippled] as a collated screen.

2) However, I am still looking for TB3 dock which makes operating the notebook simpler without a need to plug-in/out cables instantly + not occupying both TB3 ports with monitor cables (thus no PD option).

 

So - the question which of the decks are now tested by you and working fine?

 

My ideal configuration is a combination of the following:

- two external UHD (4k2k) monitors at 60Hz (notebook screen as the third display not mandatory)

- PD with more or less decent W

- a spare TB3 on the dock is favoured for chaining up devices in future (not mandatory).

 

Note. I am considering a real host GPU based options (Display Link 6950 docks work fine but not suited that well for my business).

Re: Yoga 920 and Thunderbolt Dock

Just wanted to share my docking experience here. I don't need 4K, but I run 3 external 1080P monitors and I wanted a single cord into the laptop for all of that plus power, sound, and an external hard drive, keyboard/mouse, etc.

I have the 920 13IKB and bought a j5Create USB-C HDMI adapter with Power Delivery 2.0 and an HDMI out and a USB 3.0 port, and I also bought the j5Create USB 3.0 docking station with HDMI, VGA, 2xUSB3.0 and LAN port. I then daisy chained the dock into the USB-C adapter and plugged everything in, including power. I also have a small 4 port USB 2.0 hub plugged into the dock for the keyboard, webcam, etc. I have a 6 foot USB-C extension cable so all the messy cables sit behind my monitors. My sound outputs through the HDMI to a Sharp TV I use as a monitor and I use the output channel to drive it to my stereo. I don't have a solution for my mic yet because I have a condensor, but if I just wanted to use the mic on my webcam it works through the USB. I may buy an external sound card.

Performance is more than satisfactory. I can run full HD video on all the screens and move smoothly between them. I have 70-80 MB/s transfer rates with the external hard drive (same as if plugged directly into the Yoga) and I still have the USB 3.0 slot on the other side to stick a thumb drive in. If you want to spring for a USB 3.0 hub it should scream even with multiple devices.

 

Total cost for my 'dock' is $150 or so, including the USB 2.0 hub, which was $15. The USB 3.0 dock is $80 and the USB-C HDMI adapter is $55. 

I did get the TB3 drivers and I updated the firmware for the TB ports from the Lenovo site. My Windows and all drivers are fully up to date, including chipset and graphics. I installed each piece of the 'dock' individually and in sequence after much experimentation. I had real trouble making anything work before updating the firmware and drivers, but once that was done it was smooth sailing.

So maybe not the most elegant solution, but it works and everything is on one cable including power for $150 plus tax. Oh, and I got the 920 on an open box special for $942, so I really feel like a winner :D

Hope this helps someone!

 

Edit: Forgot to note that I bought everything at Best Buy.

> j5Create USB 3.0 docking station with HDMI,

 

>  I can run full HD video on all the screens 

 

That simply doesn't add up. Such a docking station would have a DisplayLink chip in it and there's not enough bandwidth from host to the DL chip for an 1080p movie. You need 5-8 gbps at least for that which USB 3.1 Gen 1 doesn't have.

I watch '1080p' movies over it, it's fine with me, but that's not the purpose of this laptop anyway. It does provide a passable media experience as far as I'm concerned. The more important thing to me is that I can have my email, calendar, OneNote, and whatever primary thing I'm working on each on their own screen with plenty of room for sticky notes. As a workstation, it's working out great ;)

Re: Yoga 920 and Thunderbolt Dock

Having been satisfied with the Thinkpad TB Dock for a while, I thought everything was great. But recently I noticed two issues:

1. With just the TB Dock connection plugged in to Yoga 920, it isn't always charging. I am now plugging the power adaptor that came with the 920 also to make sure it is alwasy charging.

 

2. After the 920 goes to sleep, the ethernet on the TP Dock goes crazy after a while. I haven't figure out after how long, but my  entire home network (GigaE) become unusable as soon as that starts. It took me a while to figure out the cause. Now I have to remember unplug the ethernet cable from that dock after stop using 920. This is very annoying because I could forget and the network will stop working after a while. I wonder if other people see this.

You're right, I've misrepresented what I mean. I run movies to the display that is coming out of the USB-C via HDMI and run the other two displays at 1920X1080. I don't have a BluRay or anything, and I know a lot of my movies are certainly not actually full 1080p no matter what the file says. I run YouTube and other online video on all three screens with no issues. I'm not looking critically at the displays to measure video quality, but I don't notice that it's bad.

 

So to be clear, my solution is for working not for watching TV and movies, but I do both with it and it meets my expectations totally.
