If anyone is curious, I’ve bought both of sets over the past 30 days. I started with the Samsung NU6900 because on the showroom floor it looked the best. When I got it home it wasn’t nearly bright enough, especially for HDR and I was CONSTANTLY having to adjust the brightness/contrast between scenes of movies and games. I exchanged it today for the Vizio E Series (currently on sale at Best Buy for $309) and my goodness, what an improvement. It’s so much better than the Samsung in almost all areas. If you’re on the fence, do yourself a favor, don’t even think about the Samsung 6900/7100 series.
