Review: Lenovo Thinkpad Thunderbolt 4 Dock does support HDMI 2.1 output with 4k@120hz to LG CX - 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
Review: Worked "ok" with lag with one monitor, adding a second (third screen) causes random crashing - Worked ok at first, but obvious lag on second monitor. If you add a third monitor it becomes unstable- will just randomly drop 3rd and sometimes both monitors, consolidating everything down to just the laptop. Sometimes it comes back on it's own in a couple seconds, otherwise you have to unplug it from the laptop and replug it. Pretty sad fail given that other docks are significantly more stable. Running 4k monitors and a 4k laptop might be too much but then it shouldn't claim it works for that.

## Questions & Answers

**Q: Does this lenovo tb4 dock have realtek 8153 or intel i225 ethernet?**
A: The circuit board appears to have both Realtek 8153 and Intel i225 chips. When connected to a Surface Pro 8 or Surface Laptop Studio, only the Realtek Ethernet device appears in device manager. The Intel i225 is nowhere to be found. Connecting the Dock to other laptops may result in different behavior.

**Q: Funciona con lenovo e15?**
A: The item is compatible with the following E15 Lenovo models: E15 G4-21E6 - E15 Gen 4 and E15 G4-21E7 - E15 Gen 4.

**Q: Is this compatible with Thinkbook 15 G4?**
A: yes, I have a Thinkbook 15 G4.

**Q: My laptop is giving me a charging error when I reboot while connected to the dock. Is this normal?**
A: There could be a few reasons why this is happening. The 1st being a compatibility error, I am sure you checked compatibility before buying. The 2nd is that a driver or utility update is needed, these are free downloads on Lenovo sight. The 3rd being a loose ac connection. The 4th being an internal error with your laptop due to a MS Windows update. If you have an external battery, turn off your system, remove and re-install the external battery.  If not, be sure that the update was fully installed. 
Supported OS:Win10 64 bit, Win 11 64 bit.
The last issue would be that you received a non-USA version of 40B00135US. 
The USA version has the suffix "US" on the part # (suffix with : UK, CN, AS, ect ect  are all docks made for a different country). 
Always be sure to received USA Product, 40B00135US, UPC	195348677271, the original Lenovo USA packaging should be present and it needs to be sealed with the Red Lenovo authenticity seal.

### ⭐⭐⭐⭐⭐ Stable and fast

I switched from a HP G5 dock and my connectivity and performance improved dramatically. Monitor turns on in no time when moving mouse or using the keyboard. Exactly what I was looking for
