PS5 and Portable Black and White CRT TV | Retro Gaming on PS5

I took an old portable CRT TV and connected a Playstation 5 to it. This is not just a CRT TV, it is also a black and white version. This is a small TV with a screen size of 5 inches..
Imagine my surprise when I saw the PS 5 menu on the old TV screen? It really works. Using a simple adapter (from composite RCA connectors to HDMI) everything worked.
