So I am in no position to help you but I do have a very strange and hypothetical (ish) question:
How feasible would it be to hack a monitors firmware and use it to send and receive data, assuming that the data being sent is encoded on, say, the green color channel of said monitor and you had an sdr or some specially configured device set up somewhere to help make this very specific and bizarre idea work?
