Here I am demonstrating how to hook your 4k retro HDMI Game stick up to your CRT TV or Monitor that supports Scart. in this video you will need the scaler converter box and a few other cables. Plug in acordingly and set your chaneel. in my case it was on AV but depends all CRT TV's are different ans some older ones tha don't support scart so you will need an RF Modulator.
