I just received my LE55FHDF3300ZTA last week. Since then, I've been playing with the color/display controls and trying to find the perfect settings. Since I'm not an a/v-ophile, I'm completely happy with my purchase. I was looking at the Vizio 60" LED, but for $300 less, figured I'd give TCL a chance (like I did when I bought my first Vizio).
I actually came back here (don't visit often) to find some settings others may have found to work the best, but I guess I'm on my own (a good thing...something to learn). Anyway, people have been asking, figured I'd say that I like it and it's a great TV so far. Plus, going from 42" to 55" was rather astonishing...once I got over the seasickness and backed up another foot or two.
