Hello everyone, i am looking for a Thunderbolt 3 Dock with 2K @ 144Hz support - I know that the CalDigit TS3 Plus can do it, but it is sold out here in Europe. Does anyone know a good alternative?

2K 144Hz only requires DisplayPort 1.2 (four lanes). Any Thunderbolt 3 device with a DisplayPort port or a 2nd Thunderbolt port can do that. Even Thunderbolt 2 can do it. 2K 144Hz might be doable with an HDMI 2.0 output as well.

If you want a USB-C dock instead of Thunderbolt 2/3 then you need one of these:
A) a USB-C dock that does USB 2.0 only (not USB 3.x so that DisplayPort can have 4 lanes) such as one from Cable Matters.
B) a USB-C dock with a DisplayPort 1.4 MST Hub supporting DSC such as the CalDigit SOHO (but DSC is not supported in Big Sur and is not supported by some GPUs)
