I put that walmart vizio 65" in the basement - I didnt have anything plugged up at the time. I just wanted to see how well the wireless was with 4k that far away. The video turned out to be great. The refresh is like a true 60 hz, but it has some kind of janky software that seems to clean it up a bit. For watching movies and such down there, it turned out to be a good little expenditure. The biggest gripe I have, is like others have said about other televisions - they skipped way to much on the sound quality. Those speakers sound like the stereo's people buy for $5 from Big Lots to take with them to work cause they know if a board lands on it, it didnt cost them but $5. ON THE PLUS SIDE - it has all the connections needed for outstanding sound. Once I hooked up the surround sound, the atmosphere was perfect.
When the TV was upstairs, temperature around 70F before my Nest install, my g/f said the stream would just abruptly end. Ive never experienced it, but looking it up - it overheats at times? But now its down stairs, mounted properly, and it stays a bit too cold down there at times (65 to 68F)- I watched that TV while I was working on the couch all day and basically all night once my g/f got home. Never did it then, so maybe it happens? But I cant get it to replicate, and if its a heat issue - the colder temperatures, or the mounting, definitely fixed it afaik.
I've put most of the stuff in my house on "Google Home" and the google assistant makes everything I do a breeze. Granted, some asshole hacker could always come in one day - raise my blinds, jack my temperature all the way up on heat, blast all my tv's on rap - but thats about all hes going to be able to do so I'll just have to take that chance ha! Reason I brought it up was because that tv has chrome cast on it. So I can literally cast a show, youtube video etc. to any TV in the house from my PC. Big fan of Google Home so far. I installed these powered vents and temperature gauges in the upstairs bedrooms and the downstairs entertainment room. That worked well enough, but the air just didnt seem to ever get upstairs even with the rest of the vents closing up. There was just too much pressure in the system. The Nest I have led me down an HVAC path and the solution was just to put powered fans inside of my ventilation, which in hindsight was relatively cheap. That fixed the issue for upstairs. I just dont know how to keep the basement from dropping below 68F now?
