This issue was really weird. I stopped using one-key-hidpi for a bit because it was not working, but kept its settings stored. Then yesterday it magically gave me the HiDPI options on my 4k TV. I used it for a bit, got 1440p HiDPI, icon changed too.. Then when I turned off and on it today, HiDPI was no longer working. I know people say it isnt working, but I am really confused by why it did work for a little bit for me.
