I think you need to look for something that implements the WiFi Display protocol (MiraCast), for example MiracleCast.

Interesting! Have you used it? I hope these kind of tools evolve to open, near turnkey, inexpensive two-part wireless hardware kits: plug in a caster/sender device to the PC or Raspberry HDMI out port and plug in the receiver to either the HDMI in port on a display/TV or to USB OTG on an old android phone/tablet (maybe flashed with a custom ROM) and shazam: wireless screen over direct Wi-Fi. Pair them by temporarily connecting a cable from receiver to sender and press a hardware button. Bonus feature would be to allow multiple simultaneous receiver devices for one sender device.

The little HDMI to USB webcam adapter looks very useful! Hackaday wrote about it recently too

Only problem seems to be that there are several similar products on Amazon et al but quality can be hit or miss.

Another issue is how well the editor/program integrates into a system where there are many types of files. Again I don't think any of them are great for doing this.

Yeah, there is a lot of friction to overcome there. I have an AutoHotkey script setup: I put no-markup filepaths or filenames in the plaintext notes. Later I select a whole or part of such a string (or put the cursor inside it) and press a hotkey. The script detects if there is a unique file anywhere matching the string pattern and takes action depending on filetype. E.g. open PDF in pdf viewer, open source code file in VS Code and so on. If multiple files match action alternatives are shown. If no file is matched alternatives to open up a file search in Everything or do a Google search are shown. Since this works on any text selection anywhere I can use the same approach across different apps, local or web based. For example I use it also in notes written in Google Docs, in effect links from Docs to the local filesystem. I considered making it a NANY tool this year but the thing is still evolving and is very tied to my own note taking setup and how I tend to use the target files, so difficult to make into a more general application yet. But I think this kind of customizable inbetween tool is the best option, since it is unlikely that any specific note taking app will also be a best fit for how you want to deal with various other types of files.
