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

Recently want to upgrade my Lenovo Thinkpad TB3 dock to this new version, but I found even it fully support Lenovo's own legion laptop with HDMI 2.1 over 4k@120hz. I checked the display info, it shows the card is wired through 'display port' internally. confirmed in game, it's just 4k@120hz, no G-sync, I think it's a limitation on LG CX, it's a special protocol used by LG and nvidia to arrange G-sync compatible. It couldn't output any HDMI signal from my Intel 2019 MacBook Pro 16. I had to use a downstream TB4 port on this dock then connect another USB-C to HDMI 2.0 cable and output to my tv, of course it's limited to 4k 60hz However, it does support my Intel 2020 MacBook Pro 13 and 2021 MacBook Pro 16 which is very strange. Of course, all of them are HDMI 2.0 due to limitation of MacOS And it does USB PD charge with 92w to MacBook Pro but it can't deliver any power to its own Lenovo Legion 7i, even though Legion can support 100w PD charging from TB4 port. Now I'm very confused by this dock. btw, firmware updated to newest 1.07 on lenovo website. Update on 6/5/2023: After a firmware update a while ago, it finally support M1 MacBook output 4k@60hz directly from HDMI port, but too bad due to Mac limitation, it's only HDMI 2.0 signal so no 4k@120hz. But I do "solve" this problem by recent hack from community using a special adapter to convert TB/DP alt signal to HDMI 2.1, I won't go into details, just search Thunderbolt -> HDMI 2.1 solution for M1/2 Mac for solution

So I've got both Ryzen and Intel laptops and even though many of my docks worked okay, they had one or more issues with my dual 34" 3440x1440 144MHz setup. Most won't output the 100W PD I need. Others would have graphic issues or audio cutouts - all sorts of things would crop up. This Lenovo dock has worked really well for me. I did run into some issues where my webcam mic would just stop working on calls, but a firmware update a month or two ago fixed it and it has been solid. Really pleased with this unit.

BUYER BEWARE: This dock is NOT compatible with all Lenovo Thinkpad machines. I have had terrible performance trying to run a pair of 4k monitors. I believe is a power related throttling issue occurring, for which there is no fix. I troubleshooted it with Lenovo Premier Services, who said the dock is not compatible with my laptop, and because it is purchased through amazon, they would not help me further. There is no note in the description that flags a buyer to check compatibility. And, their compatibility matrix on Lenovo.com is an excel file that you have page through. They also would not entertain the idea that the dock could be defective. Having owned many Lenovo docks over the past 10 years, I would purchase something else, as other docks have been notoriously problematic. I feel silly for thinking this would be different. It took me a few months to figure out it wasn't my laptop, but rather the dock, that was the issue, hence the reason it was out of the standard return period. UPDATE: Amazon refunded my purchase without any hesitation.

I purchased this docking station to use with my Lenovo X1 Carbon top of line laptop. I initially tried to connect my Dell monitor (with built in speakers) to the HDMI port on this dock. The monitor worked fine, but the sound in the monitor speakers would die out in 3-5 minutes after bootup. Lenovo phone support was outstanding. I was able to get someone on the phone in minutes, they installed the Lenovo Dock Manager on my laptop, updated the firmware to latest version). Unfortunately, even this did not resolve the problem with the HDMI port in my unit (for monitor sound). I replaced the HDMI cable with a Display Port cable, and the DELL monitor AND its built-in speakers worked fine. I decided to keep the LENOVO dock for one big reason - it boots up my laptop on startup (my ACER dock could not), and it does a great job overall. You can also daisy chain this LENOVO dock with another dock for additional ports. I use my ACER dock for SD card ports (big and small) etc.

Exactly what I needed. My set up is a Lenovo lap top which I have on a lap top stand. I hide this underneath the stand so I can free up more space. I have two monitors (Laptop sits in the middle of the two monitors) - wireless mouse and keyboard. All ports hold all of it. Excellent set up for folks with more than one monitor.

Great docking station!!!!

Firrst: You need to download the drivers and firmware updates from the Lenovo website before attempting to use this. There probably should have been instructions about that in the packaging. I confirmed that is was compatible with my device before buying it but it would not charge my computer or display the attached monitors. I bought a new computer since Lenovo's site said it would no longer create updates/support my computer. It was an excuse to buy a new computer and not return the docking station. I bought the newest model computer that is 100% compatible with this docking station. The docking station powers the laptop but the laptop cannot receive software updates while plugged into the docking station. The Lenovo computer identifies this Lenovo docking station as malware and the BIOS will not boot up while attached to this. This means I have to unplug the docking station from my laptop nearly every time I open it up to log on. My two attached monitors rarely work while plugged in via the docking station and the computer is hallucinating a 4th monitor that doesn't exist. Lenovo states that this is a known issue of the docking station. I'm unsure why they would roll out production with such a huge bug left to fix. Had I known all this beforehand, I would have gotten an older model docking station that's gone through many more updates and patches so all the bugs were already corrected. Other than that, sleek design, doesn't overheat, plenty of ports for all your needs.

I was torn between the Lenovo and Dell docking stations because I wanted one that was easy to use and worked well with most laptops. I ended up going with the Lenovo since my current work laptop is the same brand and it was cheaper. Works fine with no monitor glitches.

This docking station works seamlessly with my Lenovo ThinkPad and should also be compatible with other brands. Just make sure you use the Thunderbolt cable, since it can be easy to mix it up with a regular USB-C cable. The build quality and performance are excellent, and I’d definitely recommend it for a home or office workstation setup.

Received a used , damaged, faulty docking station. The device was faulty and keeps disconnecting from display. Luckily i had taken an unboxing video and Amazon helped with a refund.

Fonctionne très bien avec mon Thinkpad. Le prix est élevé mais la facilité de ne brancher qu'un seul fil est un bienfait bienvenu.

C'est une pièce d'équipement qui va assurément sauvegarder les connecteurs de mon tout nouveau portable. Il accompagne un ThinkPad T16. Le Thunderbolt 4 fonctionne parfaitement, donc un seul branchement et tout est présent sans hésitations. Je recommande pour tout produit ThinkPad.

Great display dock but the C cable is like 12" long and useless. Luckily I found a 3' Lenovo C cable at work in a pile on junk for a thunderbolt 3 . I would recommend the 4 over the 3 as the power is much better at 135 vs 90 and it also has type C charging unlike the T3.
