The sound IS TERRIBLE! Thanks goodness we had auxiliary speakers that we are using and 'shutting out the audio' from the tv. The picture quality is less than what I expected. We have an older Samsung (5yrs) and the picture is much better. I would not purchase this TV again.
The tv is pretty much great for picture. The sound could be better. No mirroring on this model. And cannot search and purchase apps on this model.
Navigating web services with remote is ridiculous. Too much lag.
TV is great other than that. Picture, color, sound, services/apps, etc. are terrific. No tearing or pixelation even with sports or fast-action movies.
We have had this tv almost 2 years and never had a problem with it. The picture is sharp and clear the colors are natural and the sound is clear. We enjoy it every day.
