Re: Yoga 720 dock compatibility

2018-02-09, 21:01 PM

I just got the 720 with 15", 16gb RAM and GTX 1050 .  I've been running the thunderbolt 3 dock for a couple of days.  After it upgraded its firmware today my external monitors now flicker.  Even if I only have one 2560x1440 monitor it still flickers.

 

All i can figure is that it's the firmware on this thing.  Its the 40AC0135US   Any way to roll back the firmware on this?  I already tried rolling back the intel driver to the oldes one on this page, but it made no difference.

 https://downloadcenter.intel.com/product/98909/Intel-HD-Graphics-630

 

To add to the confusion, when I hook up the dock to my ASUS Laptop, everything works fine.  So there must be something up with the 720.  I don't know if it has issues with the dock or the monitors or what.

 

This is pretty frustrating, I'm probably going to return the laptop if it can't even handle one additional monitor via the dock.

OK - all is good. I'm a little embarrassed to admit that I just double checked BIOS. After updating BIOS to the current 4MCN28WW(V2.00) 03 Dec 2017 all is good again.

No flickering and the dock works too. Hopefully this helps someone who had the same problem.

Hi snake, have you tried daisy-chaining 2 QHD monitor from the thunderbolt port ?
By this I mean, using USB-C to DP cable from laptop to first monitor and then daisy-chain from first to second monitor.

Re: Yoga 720 dock compatibility

I've read this thread bit by bit over the past few days and my head is spinning - not great Lenovo.... !

 

I'm not in the dual 4k screen box, but have a taxing requirement of a different nature.

 

I have the Yoga 720 15" 1080 Intel Model.

 

I've attached a graphic of my basic requirement for a dock which can handle multiple Thunderbolt devices

 

- 1 X Thunderbolt 3 ProAudio Motu interface

- 1 X HDMI for a 21:9 WQHD screen

- 1 X DVI/VGA Output for an additional 1080 HD screen

- 1 X Thunderbolt 2 SSD Bay 

 

I'll many USB devices - around 15 in total - various studio music making USB devices. 

Almost all are fine without HiSpeed USB and USB 2 will be fine.

 

I'm considering the Lenovo Thunderbolt 3 Dock, but perhaps an aftermarket would be more suitable for this requirement - quite frankly I'd need to re-read the entire thread to convince myself and my head hurts after the first read !

 

Thanks so much,

 

Val.

Hi ValUe, the Lenovo TB3-Dock should be fine for most of your requirements. The only problem I see is a parallel usage (read or write does not matter) of multiple drives while having plugged two screens and the ProAudio Motu interface (which I do not know). My experience with all the usb-c-docks is that they do not like heavy load. Effects of heavy loads were (in my case) flickering screens and a sudden deactivaton of the LAN-Interface. That brought me to the Lenovo TB3-Dock. The point is, that by using many drives you could experience similar problems because your data-stream could exeed the thunderbolt-bandwith. Even if you say that USB-Speed-would be enough for your drives I am not sure if the TB3-Dock would prioritize the ProAudio and the screens. The only way to be sure would be using an usb-2-cabel or usb-2-hub to connect your drives.

How do I leave BAD REVIEWS on a Lenovo product?

Hi Poddi,

 

That's exactly what I'm worried about - bandwidth.

I've also just made a change and bought a 38" UltraWide but I don't think it will be a problem.

 

TB3 with an active cable if i understand correctly is 40gb/ps theoritical max (20 gb/ps on an inactive cable) - that's correct right ?.

 

I guess I need to figure out what the max bandwidth of each of the devices is - as running 32 tracks IO on the audio interface, along with some heavy drive reading across multiple SSD's over that TB3 input could cause one or more devices to start skipping & jumping.

 

Stability is key here - it's a completely unusable system for me if there are artifacts in the system !

 

Val.

I have a 720 13" . I don't need 4k on my dual monitors. Just using for office work. Basic stuff.

Has anyone confirmed what will work for sure? Daisy- chaining them? Dock?

Re: Yoga 720 dock compatibility

I'm wondering if I can use an adapter I've got now, it's a Lenovo that connects to the thunderbolt port, it's got 3 usb ports, one a 3.0, and one hdmi. I've got a 27 inch connected to the hdmi port on it now, works great as is...  Wondering if I can connect another monitor via the usb 3.0 port via a usb-hdmi adapter and then extend them?

Unfortunately, it does not work with https://www.amazon.com/Wavlink-Thunderbolt-DisplayPort-Adapter-Converter/dp/B07CLLX6XS

I am out of ideas and very disappointed of the poor technical details that Lenovo have provided for that laptop.
