Did about a year of a docked laptop setup. Basically anything CableMatters is good. I used the 201331-BLK-J (DisplayPort Ultrawide) and the 201310-BLK-N (HDMI 2.1 OLED TV).
I would pass through my 100W charger and it worked fine. Audio would be sent over the video connection which meant no driver issues. I had speakers connected to the monitor.
The rest of the USB ports were miscellaneous and at least one cable going to the monitor to use its USB ports.
Haha, yeah I see have one. It seems targeted for Samsung DeX and/or using it on a TV. It has a straight up a wireless keyboard on the back of the remote. Could make sense since, if you're trying to use it as an Android TV replacement, you can't use the on-screen keyboard.
Their website is easier to find stuff and each product has an Amazon link.
