LenovoThinkPad Universal Thunderbolt 4 Dock, 4 Displays, Dynamic Power Charging up to 100W, Black

I bought this dock and used it to drive a display on a gaming-focused desktop at 1440p and 165hz over displayport. I also connected ethernet, keyboard, mouse, and speakers (via a 3.5mm jack) over a single thunderbolt 4 cable from the dock to my desktop PC into an ASUS ThunderboltEX 4 pcie card. I also used it at one point to drive the 1440p 165hz display and an additional 1080p 60hz display. I had no issues related to the dock at all.I am now using it in a music-focused workstation with a Dell XPS 15 laptop with thunderbolt 4. With the ports and power delivery, and the ability to drive high-bandwidth displays, I think it is comparable to the Caldigit Thunderbolt 4 dock that is almost twice as much money. Great device!

This is a piece of junk. I got a new Lenovo laptop from work which wasn’t compatible with my old Lenovo docking station, which was irritating given it wasn’t that old and should have been compatible. So I went and bought this one to hook up to my 3 monitors, 2 DP and 1 HDMI. Nothing worked, it even gave me an error when I used the power cord that came with the docking station stating I needed to use the power cord that came with the laptop- these are both Lenovo products and the docking station power cord is incompatible. I returned it and got a different brand $44 docking station and it worked great! Good ridden to this piece of garbage!

I normally don't write reviews, however I had to do quite a bit of research before I landed on this one. Disclaimer towards all my views here, I bought this "Very Good" condition used on Amazon for around 140$ shipped. My attitude and rating reflect that price point.I am able to connect this to my Macbook, it charges my laptop and I am able to get two DISTINCT external screens. It took some fiddling to do this. I have two external monitors I use, a Samsung Neo G8 32inch 4k 240HZ and LG 27inch 4k 144Hz.My initial setup was to use this dock to power my mac and run the Neo G8 through the display port with a seperate thunderbolt input for the LG direct into the laptop via DP to TB cable. I was not able to get the Neo G8 to start up with either DP port on the dock. Neither the standalone nor the one that shares its chipset with the HDMI. I tried installing the DisplayLink drivers but it didn't recognize my monitors. I realized it may be my settings and permissions, but I'd have to weaken security too much through the kernel to do this just for DisplayLink. However, I found that the port was able to support DP to my LG monitor. So using DP to the LG, and then connecting my second monitor to the TB4 port on the dock via a DP to TB cable, I was able to get two distinct screens out of this. So before you go thinking that it doesn't work from one of the DP ports, check against another monitor. And use the DP port that's standalone (not stacked with HDMI) for testing, that one runs on a better chipset. Note that I believe that if you want to drive two screens on this, one of them must use the TB4 port. The others will all mirror each other if you're using a Mac.The Macbook works with this, but it doesn't play well. For my needs it's sufficient after passing the setup headache. Things I still have to watch it for. I use my dock with my laptop in clamshell mode, laptop lid closed. Sometimes it wont wake from sleep using my keyboard, meaning I have to open the laptop, login. Sometimes an additional step of replugging the port in is needed. The audio jack in the front works from single port mic and audio. It's well powered but dont plug your headphones in and out all the time when it's docked. The system has to re-register that there is an audio device present and sometimes it takes a bit.That all being said, I believe this is one of the better TB4 ports that you can make work with the Mac M1. If I had to spend 300$ on a dock, I'd probably go with Caldigit, more straight forward especially with everything having a thunderbolt converter cable these days. But for that price I could buy two of these at today's price.Best of luck.

Giving this piece of junk two stars is being kind. This review is a combination review of both Amazon's service and the product itself.First, I originally received this product in the mail with just the dock itself in plastic wrap in an amazon box. No power supply, and no thunderbolt cable. I purchased it new, not refurbished. So i'm not sure why they didnt bother shipping it in the actual lenovo packaging and sans power supply and thunderbolt cable. Very sketchy on Amazon's part. Then after waiting a couple of days for the replacement to arrive it arrives, i'm ready to let bygones be bygones and move on with my life. This product does not function as advertised. First off, i'm not sure where they get the nerve saying it can power up to four 4k monitors. It can barely power one monitor at 2k and another at 1080. WTH?! I tried plugging in a third monitor and it crashed the 1080 monitor.Theres also the problem with screen flickering that people have been complaining about in review. This is a major problem on mine as well. I also have a problem where if i unplug one display, they both crash out and then i have to go through the headache of switching both display cables around or completely rebooting the dock to get everything back to normal. This whole experience has been a headache and i highly recommend you look elsewhere for your dock needs. I just grabbed the Plugable 13 in 1 USB C dock ( https://www.amazon.com/dp/B0779K9DG2?ref=ppx_yo2ov_dt_b_fed_asin_title ) and so far it lives up to the name. I plugged it in and it worked great. Please do not pick up the lenovo dock. it is trash.

I have both a Lenovo X1 Carbon Gen 9 and 10, and I am able to run two external 4k displays (3840 x 2160) at 60Hz over DisplayPort (in addition to the built in display). It also handles all of my USB devices just fine. I'm running Ubuntu Linux on both laptops.I was pretty confused about USB-C vs Thunderbolt, and I had been using the "Cable Matters 8-in-1 Portable 40Gbps USB4 ... , Compatible with Thunderbolt 4" dock but I was only able to reliably get one external 4k display working at 30 Hz. I could occasionally get 2 external 4k displays working at 30 Hz, but I couldn't reliably reenact the magical incantations necessary for this.
