adjusting aspect ratio on roku express (2019) on CRT tv, "overscan"
I have an old magnavox CRT tv with a roku hooked up. there are no options on the tv menu to adjust the display size. it is showing me all content in 16:9 HDTV size when i need 4:3 standard (square tv), the edges are cut off. there is no option on the settings to change this. the only thing that is listed in display settings is 1080p or 720p. HELP.
