I bought this one. The bad thing is that it only supports 1080p. https://item.jd.com/1167602.html

WTF! Excited!

wu-hongjun commented

Still waiting for TB3 eGPU tweaks...

I got a Plugable USB3-6950-HDMI and it is currently working. 4K60P. @darkal @zysuper

I find lenovo hybrid usb type-c/type-a dock(40AF0135CN/40AF0135US) which power by displaylink's resolution , also support 2* 4K display, only USD 120.

I got the dock (40AF0135CN), everything is ok, but like your adapter, there will be fps loss when scale 4K into 1080P, this should be the imperfection of the displaylink's driver itself.
Still expecting the Thunderbolt 3 external graphics card or dGPU to work properly...sad...

After upgrade displaylink's driver to v5.2 , 1080P HiDPI performance has been improved , but it has not been completely smooth

Good to know, I am away from home therefore don’t have my monitor with me (And I upgraded to 10.15 beta) so any Displaylink testing on my end will be postponed to late September when I get back to the States and Displaylink release their driver for 10.15. Apple says they will have a dedicated API for writing drivers (mainly for PCIE devices) so hopefully eGPU and Displaylink solution would get better as Catalina slowly arrives.

Also, just curious, does your dock work without the power plug in?

darkal commented

Nope, this dock has to be plugged in to work properly.

Got this from ebay for $14. Works fine on Catalina with beta drivers. Though I couldn't manage to activate HiDPI on 1080p.

所以到目前为止 通过雷电3扩展显示器依然不可用是吗

一定要用那款外置显卡才行吗，可以使用一个雷电拓展坞外接显示器吗，就想Windows下那样？

我可以确认，USB-C外接联想扩展坞输出到外置显示器正常工作，我的配置是：
x1e gen1, ThinkPad Hybrid USB-C with USB-A Dock (40AF), DELL U3219Q

有试过普通的雷电拓展坞吗？我不确定联想的这个拓展坞是否也是属于自带外置显卡的那种类型。

wdde commented

两三百块那种？别想了，要是那种能用的话早就无需讨论了，dell有一款USBc 扩展我试过，不能用。目前看displaylink的才能用

联想的这个USB-C with USB-A Dock扩展坞是displaylink芯片的

I can confirm that the Plugable USB-C to dual 4k@60 DisplayLink adapter works on a X1E Gen 2

👍

Scaling the 4k down to 1440p causes a pretty significant amount of CPU usage and lag, but at native or scaled to 1080p runs like dream

are you sure about Plugable USB3-6950-HDMI. I asked Plugable but they said our adapter is not recommended or supported on :((( is it here: https://www.ebay.com/itm/Plugable-USB-3-0-Dual-4K-HDMI-2-0-Adapter-with-Gigabit-Ethernet-for-Windows/253271410293?epid=24008967917&hash=item3af8270675:g:lQMAAOSwkLhaFMey:sc:USPSPriority!97078!US!-1

Mine is working, at least, and that is all I can tell you. When in doubt, try find somewhere that supports free return policy so at least you can return it.

Hey i tested these 2 with an thinkpad p52 on catalina.
(https://www.amazon.de/gp/product/B074743NHP/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

Both work. The Cable Matters one had really dark graphics.
The Pluggable works great even with adapter to HDMI and VGA.
I couldn't get the Pluggable HDMI Version in Germany.

Hey guys, has anyone tried ThinkPad USB3.0 dock?
The dl3900 display link chip is used.
