it could be a similar feature to the Commodore Amiga's Video Toaster; putting captions and graphics on video sources i.e. video mixing for captions and whatnot see if yours is a studio broadcast model (look for video out) or is designed for those with disabilities or if its just a mod by the previous owner to fix a weird analog board problem
@@joebro6750 Hold on I’m trying to find out I don’t have any manuals or anything like that It doesn’t really say anything on the back of the TV or anywhere on the TV itself but I’m gonna ask my grandpa he’s the one who gave me the TV might still have like a manual or some kind of receipt or something you know he’s old so he keeps stuff like that
