I bought this HDMI to Component adapter/scaler a few months ago:

I've connected several HDMI devices (PS4, Switch, RPi, and PC) to an old SD CRT TV. The TV has a special 16x9 mode, which helps for the PS4 and Switch.

It works, but text/UI elements for PS4 games are very small. Switch games looked decent.
