A:Answer The 65S535 features a Roku operating system, and the 65S546 features a Google TV operating system. While they are different TVs with different cosmetics, and different connectivity, all of our TVs in any given series are designed to work in a similar performance envelope. They give the same exceptional picture and sound performance, with the added benefit of giving customers the choice of different operating systems for their needs. Hope this helps!
