The size question settles quickly. Owners who agonized over 42 vs 48 inches, or over using a TV as a PC monitor, tend to report that the screen they were worried was too large became the one they stopped noticing after a week and would not trade down. A few who started with a larger size moved to the 42-inch and landed there for good. Gaming owners in particular say the combination of screen size and low input lag changes how much they enjoy the setup, not just how it looks.
What becomes routine is the picture itself — not in the sense that it stops being good, but in the sense that owners stop consciously remarking on it and simply use the set. Several owners note they adjusted their streaming or media source setup: running an Apple TV or media PC rather than the built-in smart platform is a common choice, mentioned as a way to get better performance and sidestep the LG software. That adjustment, once made, gets forgotten.
