Dell Thunderbolt WD22TB4 4 Dock 130W

My Dell laptop was intended for travel and presentations as well as video and photo editing. External connections are important and I wanted flexible video and monitor options in one package. Finally, I wanted a dock that would not only recharge my laptop quickly, but that would also provide sufficient power for other devices.This was the most expensive Dell option, but proved to offer the widest selection of ports and connectivity. In fact I am using a second one to use as a permanent dock replacing my older Dell desktop. The home installation is connected to two 34" high resolution monitors, to a mixer and camera and speakers and mic.On the road I use this to keep my cell phones and tablets charged along with my laptop while simultaneously connecting to TV's and projectors/sound systems. The130w power output is sufficient to meet all these needs. There are (2) fast Thunderbolt 4 ports, a USB-C 3.2 Gen 2 ort, a USB-C Multifunction DisplayPort, a USB-A 3.2 Gen 1 with Power share port, (2) USB-A 3.2 Gen 1 ports, (2) DisplayPort 1.4 video ports, a HDMI 2.0 video port, and a Gigabit Ethernet RJ45 port.Through Amazon I was able to purchase this at a substantial discount paying only $189, far less expensive than from Dell.This is the most powerful option in my opinion.

My Setup- Dell 9710 laptop (personal) or Dell Latitude 7320 laptop (work)- Both laptops have multiple Thunderbolt 4 ports, but only one is needed- Devices connected to Dock- 3 32" Monitors displaying at 4k resolution at 30hz refresh rate (2 via Displayport, and 1 via HDMi)- USB wired headset- USB dongle for wireless mouseMy goal in getting this dock was to have a clean work desk with no cables, except for the one cable going from the laptop to the dock.Ok, so before my purchase I could not figure out from the specs and from the reviews whether the Dell WD22TB4 dock can drive three 4k monitors at the same time and also drive the laptop monitor (I am noting the specific model of the Dock since Amazon seems to combine reviews of multiple Dell Docks into one listing). Short answer, Yes.I have two Dell laptops, a personal one (Dell 9710) and a work one (Latitude 7320). Both of them have at least one thunderbolt 4 port. If I connect the dock to the thunderbolt 4 port, I do not need to have any other cables connected to my laptop, since the port also provides power to the laptop.So I am able to have a very clean desk with just one cable from the laptop going to a hanging bracket hidden behind the desk where the dock is stored and where all my cable management is done. And if I want to use the external monitors with my personal laptop, I can easily swap the one cable from my work laptop to my personal laptop.In order for all three external monitors to display in 4k resolution, I had to go into the display settings and reduce the refresh rate to 30hz for all three monitors. I also needed to try different cables I had lying around the house, because even with the lower refresh rate, some of the older spec HDMI/display port cables still wouldn't display at the 4k resolution. But once the cables were sorted out, I got all three monitors to display at 4k resolution. And the laptop would also display at the max resolution (1080p for the Latitude 7320 and 4k for the Dell 9710).BTW, in case you are not aware, you can actually use your second laptop screen as a secondary screen. So I can actually use my Dell 9710 laptop screen as a fourth external monitor screen while using my Latitude 7320 work laptop. This is done via the wireless display monitor feature.

We've been looking for a dock that will work with a Macbook M1 and a Windows laptop for a while. Tried a couple of Ankur USB-C hubs, but both had different compromises and occasional USB drop outs.So far this dock seems to do everything with respect to supporting different devices with a single connection, at a reasonable price compared with other Thunderbolt/USB4 docks, and with very little compromise. It appears to be capable of delivering up to 90W of power to any USB-C device, while it is rated for up to 135W of power delivery when connected to a compatible Dell laptop.I tested on a single 1440p ultrawide monitor with a max refresh rate of 165Hz, along with a Razer wireless mouse + Logitech wireless keyboard (each with their own dongle).Note: Multiple display support will be device dependent and I did not test that.1. Macbook M1. Provides 90w of power delivery according to "system_profiler SPPowerDataType". Outputs 3440x1440 (1440p ultrawide) at 165Hz via the first displayport connector. 1440p ultrawide works at 60Hz via the HDMI connector. Also tested a logitech usb webcam with the macbook.2. Razer Blade 14 (2021 version with AMD Ryzen CPU + RTX 3070). Outputs 3440x1440 (1440p ultrawide) at 165Hz via the first displayport connector. Works well, but I needed to disable g-sync to prevent the picture dropping out when in a game*. 1440p ultrawide at 60Hz via the HDMI connector. Also tried the USB-C DP connector and that worked at 165Hz as well.3. Steam Deck. Outputs 3440x1440 (1440p ultrawide) at 100Hz via the first displayport connector. Higher display frequencies would not output. The USB-C DP port did not work with the Steam Deck.4. Asus Chromebook. Outputs 3440x1440 (1440p ultrawide) at 60Hz via the first displayport connector. I'm assuming the 60Hz is a limit of this device.5. Dell Latitude 7420. Only tested briefly and it worked as expected :-)*In the one case where I tried g-sync through the doc the screen would flash black and then back. I assume this is due to the refresh rate dropping out of a range supported by the monitor or dock, but will need to investigate more.The power button on the dock will most likely only work with a compatible Dell laptop. It *might* work with a TB4 or USB4 device as well, but I don't have one to test.
