The Dell Thunderbolt Dock WD22TB4 is compatible with MacBook Pro models, including those with Thunderbolt 3 or 4 (USB-C) ports, but there are some limitations and security issues to consider: - Charging power: The docking station can deliver up to 130 watts of power, but when used with a MacBook Pro, the charging power is limited to a maximum of 90 watts. This is because MacBooks only support USB Power Delivery 2.0 (or higher), which allows for less power than the maximum possible from the dock. - Safety: There is no indication that the docking station could harm your MacBook Pro due to the charging power as long as the above limitations are observed. The docking station is specifically certified for compatibility with Apple devices and should therefore be safe to use. - Functional limitations: There are some functional limitations when using the docking station with a MacBook Pro, such as being limited to a maximum of two external 4K monitors or one 5K monitor, and certain functions such as Multi-Stream Transport (MST) or Wake on Dock are not available. Overall, the Dell Thunderbolt Dock WD22TB4 should be safe to use with your MacBook Pro as long as you follow the specific compatibility requirements and limitations.

With this docking you should achieve 5120x1440@120hz with 8bit color mode from what we found. If you require 240Hz, we found the following model which will achieve it on this docking via DisplayPort: CalDigit TS4 (Thunderbolt, 17 ports)

According to our information, the product can be ordered for collection from the Zurich shop within one day.

All peripheral devices, i.e. monitors, mouse, keyboard, speakers, etc. and the Ethernet cable are connected to the docking station. Then all you have to do is plug a cable, the one attached to the docking station, into the notebook you want to use. The only cables that are actually needed are those that are used to connect the devices to a computer. Of course, you may need longer cables or extensions, depending on where everything is placed. If the notebook can be charged via Thunderbolt, which mine unfortunately can't, it should work with this docking station without any problems. My company Dell is quite demanding in this respect and is supplied with power without any problems. If you didn't want to change the cable from notebook to notebook, you would probably need a Thunderbolt switch. I can't say whether there is one that also manages the full charging power.

According to our information, it should not be a problem to use this docking station with an Imac 5k 2017.

The power supply for the docking station can deliver 180W, but via USB-C/Thunderbolt 90W or 130W is passed on for Dell systems. For the higher charging power, Dell has its own system for its notebooks, which HP or Lenovo also have. For high-performance notebooks, such as the Asus ROG Zephyrus M16 2023, I currently recommend using the original power supply to ensure a constant power supply.

We distinguish the products mainly because of different sources/purchase prices and for logistical reasons (different barcodes). The manufacturer number missing here should be 210-BDTD. Both items (210-BDTD and 210-BDQH) can be found as WD22TB4 at Dell: https://www.dell.com/en-us/shop/dell-thunderbolt-dock-wd22tb4/apd/210-bdqh/pc-accessories (US side) and https://www.dell.com/en-uk/shop/dell-thunderbolt-dock-wd22tb4/apd/210-bdtd/pc-accessories (UK side). Comparing the Connectivity Options item below, I find no technical difference here.
