Picture is absolutely fantastic sound quality is not good that's why we purchased a Sony soundbar to go along with it so now the sound is great. I had an issue with redeeming the free HD movie that was included with the TV and spent hours on the phone with Google and Sony finally solved the issue myself.
After a great deal of research on both oled and led tvs, I opted for the x900F model as a very good choice for a number of reasons. The tv was purported to have very good control in the area of ambient lighting. It does. The tv was reported to have an exceptional picture quality. It certainly does. Additional remotes were available easily and finally, last but not least, the level of customization with the settings menu was extraordinary.
This is a replacement warranty (upgraded) for my 2017 TV. So far I am very happy with it. It's very bright and clear. The google app is very responsive.
Moved in to a new condo a thought a new top flight tv was required. This was it. 4K is incredible. Check it out. You should see how good this really is.
