Q: alogic Thunderbolt 3 dock and t470s - 4k 60hz

Hi all, Before I blow $500 on this dock can anyone tell me if my t470s will work with it? I want to output 4k at 60hz to two monitors. https://www.alogic.co/alogic-thunderbolt-3-dual-display-docking-station-w-4k-power-delivery-black.ht... It uses HDMI for one of the outputs, and my monitors are thinkvision p27u-10's which have HDMI 2, so that shouldn't be a issue.

HiI just would like a description and confirmation on what the following options do under the Thunderbolt 3 dock in the Bios for this series laptop I tested the option "No security" and this seems to bypass the authentication pop up when logged into Windows when plugging in the Thunderbolt 3 dock. So essentially it enables network ethernet connection to work straight away Can someone tell me what the other options do?

Is there any reason I wouldn't be able to use a T470s with a Dell USB-C dock (specifically a WD15)? I know the power adapter would be different, but I can't think of any reason the USB-C wouldn't be compatible. I prefer the peripheral connections on the Dell dock to the Lenovo 40A9 (which only has DP and VGA, and is recommended for only two external monitors, whereas I'd like to be able to connect three). Also, sorry if this has been discussed before; I searched around but couldn't find the right topic.

Hi,I have a Thinkpad P50 and today my Dell Thunderbolt Dock arrived.Unfortunately, it doesn't work  (= it is not recognized in any way), although Dell specifically says that the dock also works with non-Dell Thunderbolt 3 machines. I have installed the Thunderbolt software from the P50's driver site and updated to BIOS 1.17.Lenovo released an "Intel Alpine Ridge Thunderbolt Firmware" for the P70. But there's no such firmware update on the P50's site, just the Intel Thunderbolt Software from November.The 1.17 UEFI/BIOS Update says it fixed a Thunderbolt issue, but apparently not mine Has anyone ever gotten some Thunderbolt 3 device working on the P50? I just hope this will be fixed soon, because the Thunderbolt dock seems to be the only convenient way to drive three 4K displays with the P50 (2 via Thunderbolt 3, 1 via miniDP).

Love the concept of the thunderbolt 3 dock, can't fathom how it was designed though.  On my zBook 15 G3, the power and thunderbolt ports are on the right side of the laptop.  The dock has the cable port on the left rear side, completely crossing over all the ports when you put the dock on a desk with the back facing away from  you.  Then they ship a cable that is barely long enough to put the dock directly behind the laptop and connect it.   Where do I buy a longer cable HP, please!

We recently started using Bitlocker with a PIN at startup. On all our laptops using the "old"-type dock, that you click your laptop into everything is working fine, the users put the laptops into the dock, turn it on, type in the Bitlocker PIN using the external monitor and keyboard, and then processed into Windows. Our problem is with everyone using the new Lenovo ThinkPad Thunderbolt 3 Dock. When the users connect the laptops to the dock using the cable and then power on from the dock, the laptop will power on (the LED in the ThinkPad logo lights up) but the monitors and keyboard connected to the dock is not working, and then after some time the laptop will power off again. We currently use a workaround where the users power on, type in the Bitlocker PIN and login to Windows before connecting the laptop to the dock, but this not a proper solution. We have Enabled both "Thunderbolt(TM) device" and "USB device" under "Support in Pre Boot Environment" in the "Thunderbolt 3"-menu in BIOS, but it still doesn't work. Have anyone else experienced this problem? Or does anyone know of a proper solution.

I bought two 4k monitors and after several frustrating hours figured out that the Gen 1 dock can't output 4k on two externail monitors at 60hz, this appears to be a dock limitaion only. I see that you now have a Gen 2 dock (40AN0135US) that says it will do 2x 4k @ 60hz, only problem is that every compatability cross refrence I can find does not say the gen 5 X1 Carbon supports this new dock. I don't see a good reason for it not to be compatiable, but wanted to find out for sure one way or the other before I bought it, as it is not cheap.

As the only docking solution available and moving from a more traditional dock, its less than suitable.  HP needs to make a longer cable and the end that connects to the laptop should be at a right angle.  The cable is so stiff and thick it takes nearly 4" to make the turn.  HP makes it impossible to find this out how long the cable is with out purchasing and at that point your stuck with it.  Hardly a customer satisfaction issue they should want to propigate!

Hello all,I bought a Yoga X1 2018 and during the shop they suggest the Lenovo Thunderbolt 3 Dock. Since I thought that having to disconnect only one cable when bringin the laptop from the desk to the meeting room would have been useful, I bought it.With my disappointment I setup everything and I did some tests on the laptop just to discover that the performance of the laptop when powered through the docking station are 1/3 with respect to when it's powered by the 65W power supply and 1/2 of when the laptop is on battery... (234pt vs 640pt vs 563pt | dock/65W/battery)Now since the docking station has a 135W power supply, I really can't think that this is an issue with the supply from the docking. Also since the laptop is even faster on battery I really don't understand how it could be related to the power supply... anyway I've connected both the 65W power supply and the docking and the performance are back to normal.Is there anyone who can suggest me what's going on or how to report this to Lenovo?

My company has issue me a Lenovo T470s and an Ultra Dock to replace my existing equipment. I have two external monitors connected to the docking station with display port cables. The problem that I am experiencing is that if the laptop is docked and the cover is open, I get video on the laptop display and one external monitor. The other external monitor gets no signal and goes to sleep. If I close the laptop cover, I get video on both external monitors. A co-worker told me that this was working as designed and that the solution for getting video on all three monitors was to connect one external monitor to one of the display ports and the other to the DVI port. (He hadn't tested this configuration and is using two display ports with the laptop cover closed.) I tried my coworker's suggestion and got the same result but prior to switching to DVI, I downloaded and installed the latest(?) driver for the HD Graphics 620 adapter from this website (lenovo.com) and that seemed to solve the problem (when using two display ports) but after shutting the laptop down, I had the same issue the next day. What I want, is to have the laptop cover open and still be able to use two external monitors and get optimal resolution on all three monitors. What's the best configuration for achieving this? (Don't guess, like my co-worker. Give me something you've tested and that you can confirm that it works.)

I can't update my dock since it gives an error every time I try to update. I tried manual updates but BIOS files never show up, I think the problem lies with my service code not being in the system.
I tried entering the service tag and express service tag but it says it's not a valid product. If I provide the service tag and express service tag on this forum, would it be entered in the system so to speak? I also get critical updates and when I click update, an error occurs so my dock is not in sync with my XPS in terms of drivers. When I try to do manual updates, I'm only given 3 files and can't find bios files anywhere.
