My current dock, an Anker 565, has problems when I try to output to my monitor at full settings (Samsung G5 21:9 1440p 165hz) from my laptop (Asus Zephyrus G14 2023 RTX4060) connected via the USB4 type C port connected to the dGPU. It will sometimes flicker on but primarily stays black and displays the message “not optimum mode”. For whatever reason this doesn’t happen on Windows but it hasn’t worked on any Linux distro I’ve tried.
I understand I might be pushing the 565’s bandwidth to its limit, so I’m looking to try a higher bandwidth dock to see if that will solve my issue. As such, the dock should be at least Thunderbolt 3/USB4. For ports, it needs to have DisplayPort 1.4, Ethernet, at least 3 USB A ports (preferably 4), and at least 1 USB C port that isn’t the uplink to the laptop. Since this is for testing my main requirements are affordability and a good return policy.
For what it’s worth I’m currently running CachyOS with KDE Plasma.
