USB C DOCK

[tttthhhh]

Hello, so I am new to the whole dock situation. I own a Legion Y740 and recently decided to use it as my primary computer up till now it was used mostly for travel and when I got home I would switch to a desktop. Now that is no longer an option so bought a dock so I could replicate that feeling. I bought a Totu TT-DC001A. I hooked it up and all the ports but the video output ports (HDMIx2 and display port) functioned as expected. I then went online to find drivers figuring that was the issue. I found downloads for display link manager but it still will not detect the plugged-in, monitor. What am I missing?

Hi there, welcome to the forum.

Could you please provide more information about the used Docking-Solution in fact? A product link or a datasheet about it would be very helpful.
Google is not very helpful around here, for my side it's mainly showing alternatives than a specific manufacturers manual or Product Sheet.

I would suppose it could be an issue with the handling and not assuming that you want to duplicate or expand another screen with that single USB-C connection but for that we need more information how that display you missing is trying to be connected to the Laptop you own.

There is only one docking station from Totu at the moment.

This dock is a convenient USB-C Dock that requires Thunderbolt/USB-C wirh DisplayPort Alternate mode.

Your notebook seems ro habe Thunderbolt 3 so that should work, at least with one monitor.

Did you connect the bottom USB-C Port with the notebook? Which cable do you use?

 

[tttthhhh]

Yes I used the bottom USB c port on the dock it has an image of a laptop next to it.

And which cable? You also need one that supports video aka all Thunderbolt 3 advertised cables.

I believe so I ordered a new cable. I am currently using my wife's USB-C cable that came with her MAC PRO 2018. Though I just tried to connect her laptop to the dock and it is having the same issue. Thank you for the support I hope that is all it is. I will follow up once I have another cable to test it with.

 

[M4ttX]

Yeah, I don‘t think the charging cable from Apple supports displayport alternate mode, but I haven‘t tested it so far.

Still not working this is the cable I bought and I still can not get the display to work.

If two devices don't work with the Hub, i would send it back. Even the cheapest usb-c hub should give a picture plug and play.

Maybe go for a refurbished Thunderbolt Dock from the big OEMs. Dell TB16 for example, Lenovo and HP have some too.

 

[M4ttX]

The cable is suspiciously named charging cable, maybe it is not a regular TB3 one - couldn't filter the comments.

This one works with video, but due to its length not with full data transmission speed

I got the dock to work the port on the dock is just touchy.
