I have an old school boob tube tv in my room, currently with a firestick running through a converter. It’s fine i guess, but i want something else because 1, the aspect ratio is off since it expects to be hooked up to a flatscreen, and 2 the privacy problem of running something from amazon. Is there something that could work here?
FWIW you can fix the aspect ratio issue on the firestick using ADB to force the device to display in a 4:3 resolution (except when using streaming apps that force 16:9)
If you want something privacy oriented you’ll probably need to build some kind of NUC. To my knowledge no off-the-shelf streaming device respects privacy
If you can find/download the CRT TV’s remote, it may be possible to force widescreen in the menu or adjust vertical deflection in the service menu
