Initial impression is wow.This TV is nice a big when compared to the 55" it replaced.The picture quality is good. Not OLED good, like some have tried to say. But in the rare moments of testing 4K UHD content it is more than good enough for me. Up-scaling of SDR content is good.The apps I've tried YouTube, Netflix, Fox Sports work as expected.The sound from the TV can be amazingly good for a large screen TV. I wasn't expecting much, but OTA channels with good quality sound fill the open great room with sound. Sound from attached Tivo is pretty weak and has to be turned up (level 50 to get close to the level the same channel from TV set at 26).I do like watching TV from my office (25') or living room (12') or kitchen (24'). The Roku app does help with the listening option if I need to watch something while the house is still asleep.Still there are many downsides that some may or may not be concerned with.The Roku remote works okay, but voice control rarely works on first try. Switching stations or inputs seems very slow. Volume buttons on side are way to easy to press by accident.Have yet to figure out how to make sure getting full UHD content out of Xbox One X. Need more time to figure out if something needs to be set different.Motion on this TV is not great. Background objects of a panning image become blurry, for lack of a better word. Haven't had this long enough to play with any settings that might help. Still wondering if I can handle this TV for football.This TV has noticeable reflections on the screen. Both day, from windows to the sides, and night from any lights on behind those viewing.Some ads have popped up on my screen covering the bottom fifth form time to time.And this TV doesn't like not being connected to the internet. Had a very hard time turning on the TV when it wasn't connected to wifi. It took unplugging the TV to allow me to power it on. Another thing I need to keep an eye on.Delivery was okay. Wasn't sure what they would do with the TV. Basically it was delivered into my house and set down. No unboxing to check screen for damage which fortunately I have not noticed in casual viewing so far. Make sure you pay attention to the handling instructions (pictures). You can't lift it by the top half without risking possible screen damage. Obviously you will need two reasonably strong people to set up this set. I was a bit concerned with the back of the TV having a slightly thicker bottom then the thickness of the rest of the TV for attaching wall mount brackets. It limited the placement of the brackets, meaning they had to be mounted higher up the back of the TV then I wanted to avoid the approximate 2/10" lip. The location meant the TV was a couple inches lower, but still at good height above center channel speaker.Going into this purchase I was looking for as big a screen as I could fit on my existing wall mount. Knowing I couldn't justify the cost of the 77" OLED sets, I narrowed choices down to 3, 75" sets. Decided on the lowest cost due to the slightly better viewing of SDR content versus cost. Time will tell if the reliability of this set and setting changes to help with sports motion blur make this a good purchase for me.
