Awesome Streaming Google T.V.
I recently cut the cord with my cable company since the monthly charges were really starting to get outrageous. I was on the hunt for a television that would make it easy for me to transition to more of a streaming service but still have the same features and functions of a normal cable setup. When I stumbled across this T.V., I decided to pull the trigger on it based on the features and functionality. The T.V. itself is great. I got the 55-inch version, and it fits perfectly on the wall with the television mount which I also bought from Best Buy. As soon as I turned it on, it started the setup process to connect to my Google Home system which was seamless and connected almost instantly through each step of the process. Once I had everything set up and connected to my Wi-Fi, I have not seen any lag or any instances of where the T.V. was trying to connect to the internet like some other reviewers have mentioned. The router for my internet is actually placed far away from the television downstairs on the first floor and I still get a good signal strength to the television. I am able to access and watch anything on YouTube as well as YouTube TV which I have a paid subscription for. I also added an Amazon Firestick Max to the back of it since this television has Dolby Sound capabilities, the Firestick Max has been the perfect addition for this television as I have all of my apps in once place and can easily switch between them without much effort. Overall, the television is a great addition to our home and also saves us a ton of money each month versus having old school traditional cable.

Definitely a good purchase. Picture quality is excellent. I paired this tv with a soundbar to get richer sounds though. Easy to set up. The problem I have is some apps like peacock or hulu lag a little bit when opening. Peacock is notoriously slow on all my devices though so I can't say it's only related to this tv. I just thought it would be smoother for the price I paid for this tv. I've had this tv for about a month and it froze a couple times. The only fix I know is to unplug it and plug it back in. I haven't figured how to link my soundbar to my tv, where it will power on when I power on my tv. My Fire Tv has that option in the settings. All in all a quality tv.

We have been Samsung fans for many years. We chose the Sony because the picture quality was superior in our opinion. This is our first Smart TV and was very easy to set up. We thought about adding a sound bar but the quality of the speakers are great for our use. If that changes we can always add one easily. We have this sitting on our entertainment center and the stand legs are VERY sturdy. Quite happy with our new Sony.
