Server&Client-in-1 (AiO)

and the Touch Display plug-in, right?

I am asking this annoyingly and stupidly, because while browsing through the forum I have also come to some guides describing the process as a bit more complicated (e.g., here) - however, if I understand them correctly, their issues origin from the fact that they are using “non-standard” (i.e., not the original RPi 7" 800x480) displays. Am I correct, please?

THANK YOU again!
