50lf621u21 50-inch Smart 4k Uhd With Dolby Vision

Rebecca Excellent video and sound quality Reviewed in the United States on July 17, 2020 Size: 43-inchStyle: 4K UHD with Dolby Vision DTS Virtual-XVerified Purchase This is an excellent tv. Lots of apps (Prime, Netflix, Pandora, Disney+, YouTube and many more) and the Dolby sound and video are better than expected. We typically attach an external sound system such as a speaker bar, but that will not be needed with this tv. I am very surprised with the sound quality. I specifically chose a tv with Dolby video for the quality of the picture - and it is crisp and bright. It was packaged very well and we had it up and running in a few minutes. We are very pleased with this tv! 185 people found this helpful Helpful Report abuse
