Can you explain what this is needed for?

This feature can benefit web developers and be useful for some functionalities.

Isn't very specific.

A feature request like this got shut down before out of fear that people would abuse this for cheat detection

What is the problem if it's used to detect cheaters? It's the server problem if it lead to a fake ban.

You can already do this with

print(GetConvar("profile_vidScreenType", 1))

oh ok good to know but very few people know it adding the native would make it “easier”.

Because this will lead to servers trying to force players to play in "Fullscreen" or risk being banned because of the possibility of the player cheating.

There is also no need for the server to have access to this information, unless you have another reason other than "to detect cheats"

A set screen type of Windowed or Fullscreen (with a non-default resolution) would result in this returning false. So there's no way to differentiate between a non-focused game window and these screen settings. I can't think of any use case where a script could benefit from this information.

Thank you for your contribution but our current common goal is to not increase codebase without proper reason for that. I can't find any real use case for that. If you have such use case feel free to provide it, but for now I will close this PR.
