ThinkPad Universal Thunderbolt 4 Dock - US

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.

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.

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

It's great having access to 5120 x 1440 at 120hz on my thinkpad laptop which wasn't possible on the HDMI port alone. I really like being able to just click the on button and use the laptop as a desktop.

I received it today, and it does all that I wanted it to do so far. I’m using it with a MacBook Pro M4 Max 2024, with two Full HD displays (plus the laptop’s one), one USB-C and one HDMI (not 4K, I’m a programmer, I don’t need 4K). Tested it with 3 USB-A keys and my fast SSD drive I use with Time Machine simultaneously, plus providing power to the laptop, and it works like a charm. The only downside for me is that there is only one USB-C and one USB-A ports on the front, but I knew that when I bought it, can’t complain. I didn’t test the Ethernet port, the two display ports nor the audio port, as I have no use for them.

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.
