I had to replace my old CRT a few months ago and it’s turned into a flaming minefield… the last time I did it your choices were a small telly or a big telly.
In the end it turns out LED ones are still LCD panels, it’s just the back light that is LED. Supposedly, the brightness of the LED’s is brighter but dims on the blacks so the they increase the dynamic range…
Then there was the refresh rate which turns out to be mostly marketing bullshit anyway and I haven’t seen any motion lag on a good quality TV for years.
I spent what can only be described as far too much time looking at them and I couldn’t really see much difference, even with the TV’s side by side.
I had an LG LED one in the end as it had a five year warranty (from John Lewis) and the picture quality is fantastic. You can even nerd around with the most minute colour settings if you’re a bit colour obsessed like me!
