Need an education on TV terms
I haven't bought a TV in so long. Can someone tell me what these terms mean?
"Refresh rate" I see listings with 240 Hz and 120 Hz
"Resolution" I see 2160p (4K) and 1080p
I want to buy approximately a 55" flat smart TV. Other than that I don't know what these terms mean and what else I need to know in making my choice.
