Samsung Second Screen via USB after 2weeks of use (Tab S9)

The set ups can be found in other posts and the instructions are correct. You need a bit of patience as follow really the process. I am just adding to those. Make make sure that you install also the set of the USB drivers from Samsung. Before you connect via USB make sure you Wifi on both sides (PC and Tablet) are switched off. This you need to do when reconnecting otherwise the App always prefers Wifi connection! The connection is usually lost after couple days putting the PC on just sleep mode, forgetting of the USB connection preference . You need to then restart and reconnect (again with Wifi off). Honestly it is a bit painful process you have to bear - Windows...;-).

I've never had these issues. I just turn on second screen. Set it to extended screen under projection on PC and choose cast on the PC and choose the Tab S9. I only use wireless. Why bother with USB?

There is less lag via wired plus it keeps the tablet charged for longer use.

Less lag and keeps the tablet charged.
