TBT4-UDZ

I bought this to dock a new gaming notebook to the two monitors, keyboard, mouse, speakers, mic, webcam, and other assorted odds and ends at my working desk. All of that is shared with a work notebook which has its own company-supplied "meh" quality off-brand Thunderbolt 3 dock, with both docks switching through a modern KVM so that I can jump back and forth as desired. As the new computer has a Thunderbolt 4 port, I wanted to go with a TB4 dock to allow for the possibility of higher resolution & higher refresh monitors and maybe even more of them at some point. This Plugable dock looked to be the best balance between price and features -- for the features, there just aren't that many docks at this price. A lot of the docks around this range don't even have DisplayPort, just capability for USB monitors. A lot of the ones at this price also tend to supply less power, which aren't enough for this computer. This one also seemed to make the top X on quite a few of the "best Thunderbolt 4 docks" lists. So nothing much to report in the functionality -- plug stuff in, stuff works. I had no issue with the computer locking onto the dock or the dock addressing any of the peripherals. Everything happens pretty much instantaneously. You get a nice green solid light to show successful TB connection with the computer, or white if no connection. The dock supplies 98W of power, which is enough to actively charge my power-hungry Lenovo Legion 5 Pro notebook which needs something close to that to charge while using. It's almost the 100W max for this computer for USB charging. Anyway, that certainly works. I had one hiccup -- toward the end of the first full day of use, it just stopped working at all, unable to ever establish a connection to any computer plugged into it. Swapped cable, same deal. I contacted tech support (after hours) via email and immediately got a human response acknowledging the problem, letting me know the real techs were going to be back in office first thing in the morning and would get with me, and as promised, they did, the very next day. Josh from Plugable, probably one of the most polite and pleasant people I've ever dealt with from a tech support team, was quick to ask for a bit more info, followed by acknowledgement that it appears that the dock is bad, and an offer to send out another immediately in exchange for promise of return from me using the shipping label that was to be included. Each interaction was very quick -- no long waits between emails. The package did arrive in just a couple of days and the replacement so far is working great. He mentioned really being eager to get that other one back with all of the original stuff (i.e., "please use only the new stuff [power supply, cable, etc] because we don't know which part of the old unit is the point of failure") so that they can diagnose the cause of the problem, presumably to know whether there are manufacturing or design issues to address. It's what I like to hear. Anyway, highly recommend this product. If you need it, the tech support is unbeatable. Hopefully you won't need it, and you'll have a really solid and frankly very attractive dock that looks good sitting on my desktop where my old mid-tower system used to be, along with easy access to USB ports and SD-card slots and a headphone jack.

Excellent rock solid performance from day one. We are using this with an Alienware x14 laptop with NVidia 3060 video card. Three external monitors plus the laptop screen working at the same time. Tons of USB devices attached via USB hubs connected to this dock. No problems at all. You MUST connect your laptop charger to your laptop if you want this or any other dock to work flawlessly (100w supply from a thunderbolt dock can't run a laptop that needs 130w power). Without your laptop charger attached, you will have random screen disconnects and general instability (not the docks fault). We were able to get 120hz refresh rate working with an LG C2 OLED tv.

Pese a que las especificaciones mencionan que no es compatible con Linux (me di cuenta después de hacer la compra...), me funcionó perfecto sin tener que instalar o configurar absolutamente nada (en Ubuntu 24.04). Lo uso con 3 pantallas FHD externas más la pantalla FHD interna de mi notebook, las 4 pantallas mostrando contenido distinto. No he probado el puerto de red, pero el sistema sí detecta la interfaz, así que debería funcionar sin problema también.

I’m using this Plugable TBT4-UDZ with a Mac Mini M4 (2025 base model), and it works perfectly for dual extended monitors, no drivers needed. My main display is a 34” HP ultrawide connected through DisplayPort, and the secondary 19” Samsung runs over HDMI. Both show up as separate displays, full resolution, super stable. One important tip: ➡️ Use the USB-C cable that comes in the box to connect the dock to your Mac! I originally tried a different cable I had on hand, and the monitors would not work correctly. Once I switched to the included Thunderbolt/USBC cable, everything lit up instantly. The dock gives me plenty of USB-A ports for my keyboard, mouse, webcam, and mic, plus fast Ethernet. Love the flexibility: I can disconnect one USB-C cable from my Mac Mini and plug it into my laptop (or a Windows PC) and immediately have both displays and peripherals ready to go. Exactly what I needed; plug-and-play dual monitors on modern Macs without messy adapters or driver installs. Worth the price. Highly recommended!

I purchased this a while back, and it has working well since the first day. Recently a webcam stopped working when plugged into one of the USB-A ports. I contacted customer support, and they were very quick to respond. The agent helped diagnose the problem, and after a very short delay, a replacement unit was sent (covered under warranty). The replacement worked (the problem with the webcam, and some other display issues with a specific program, were resolved). Highly recommend the product, especially after the very pleasant interaction with the support team.
