A: I highly recommend adjusting the settings. Once out of the box it looked OK to us, but I searched online reviews that have calibrated this TV and set ours exactly as those reviews tell you to. BIG difference. I cannot stress that enough. I highly doubt the in store displays are using the out of the box settings.
Q: What about the heat from the fireplace
A: Ours is atop our fireplace (gas) and we have had no problems with having it there; we kept our last TV there (a Sony LED) for 3+ years without issue as well. I hope this helps.
A: It says the actual dimensions on all the TV's if you click on the specifications tab 53.7 W x 31.1 H x 2.5 D minus 3/4" frame of course
Q: Is the optical audio output delayed to match the throughput delay of the panel
A: The specifics you are looking for were not found. Yet this Smart TV does come with multi-channel Dolby Digital sound and allows you to select the one that works best for you.
Q: What is the best viewing distance for 55, 60 and 65 in curved tvs?
A: There's not a recommend viewing distance, although most people will sit back 3x the corner-to-corner measurement. So a TV that has a 60 inch panel x 3 = 180 inches (divided by 12 for feet) = 15 feet. Of course, you can sit closer or further away, depending on your preference. Ideally, you want to sit where you can rest your eyes without having to constantly move them while watching the whole screen. That cuts down on eye fatigue and increases the enjoyment of the movie or TV experience. Thanks for your interest in Samsung products. --Mr. S
A: yes it is. was able to switch the tv from 42" to 60" using same wall mounting.
Q: Do the Samsung 4k tv's have a swivel base?
A: Not my 60 inch model. I don't think any of them have swivel bases.
