Hi, after a tv for my nana, her old box died lol, probably during some quack ranting on the starlight channel lol

She is 91 and religious and hates spending money unless to aid orgs etc, everything is very old and often ropey etc but she is very independent

So despite my advice she has a strict $300 budget which means a good used or a dse/veon etc

Id rather get a $450ish sammy or sony with decent contrast and colour but ah well

Anyone know currently what cheap tvs if any have the above? 720p is fine, all about the accurate PQ for daylight and skn tones
Are they all inferior to say sony w6/w7 and samsung mid-low lvl?
