Thanks a million, tomcctv, for the elaboration!
I saw in the manual that that camera has settings, and I failed to wonder how to access them.
In practice, I only want to access setting once, then just send the HDMI signal to my TV (and also split it to my PC). I don't plan to aim the camera in realtime.
So now I'm eager to ask you how the PC can control the camera. (It'll be awhile before I can look at the manual or maybe even read your reply, because I just got back from an ambulance trip to the ER with vertigo/nausea/head spinning.)
Specifically: Can the PC control the camera over HDMI, or will I also/instead need to connect to the PC via Ethernet? (I'm wild-guessing the latter, since I see the manual talking about a web browser interface.) Many thanks in advance! Thank goodness you replied and helped this noob! I'm so excited to sense the light at the end of this longtime project!
