Well, a little over a week in, and I'm really glad I got the 75". As I had mentioned, just measuring before I bought it made me think, "What the hell are you doing? This is ultra-ginormous and too big for your room!" Then when I set it up I said, "Well, it's kinda big, but it's not really that bad." Then yesterday as I was walking through the living room, I thought to myself, "You know, this is actually just right." Funny how it shrunk.
The picture is great. I can't tell a big difference between it and my older Samsung, but that one is not even four years old. About the only difference is that this one is Neo and that one is not. Anyway, my recommendation to anyone else who may be waffling that a new TV they're looking at may be too big, it probably won't be. I guess they're kinda like gun safes.
I went ahead and got the soundbar that was on sale at Costco. I
think the sound is better, but honestly, both this TV and my old one have really good onboard sound. With my Samsung two TVs ago, getting the soundbar (and it was a cheap one) made a HUGE difference. With this TV, it's harder to tell. The room does "fill" with sound better, and I think that turning on the speech settings has made voices clearer. Oh, and this Samsung soundbar is also cool because it's designed so that you can set it on a Samsung TV's (of the same generation) stand, and it fits EXACTLY into that space vertically so it almost looks like it's built in to the TV. Otherwise I would have had to mount it on the wall above the TV, so this was a slick option.
I'm still not sure about Atmos. I'm not sure if I can tell, and it may be because I haven't listened to the right content. I watched Top Gun Maverick the other day on Netflix, but couldn't tell if I was getting Atmos or not, other than the TV and soundbar were telling me that it was on. Yes, I did plug into the eARC HDMI port. Maybe I'm expecting too much of a difference?
A related and really stupid question: If I'm streaming through a non-Atmos Roku, would that affect Atmos? Or will Atmos always activate as long as I'm getting sound through the TV and soundbar, regardless if I'm watching content through my older non-Atmos Roku or DVDs through my older blue ray player?
