The 65 is VA panel and the 75 is an IPS-ADS panel. I only have the 65 inch, so I can't speak about the 75,but off axis viewing with any VA panel leaves a lot to be desired. It's not the worst I've ever seen, but if you have a wide viewing area it's something to consider. Other than that, the picture quality is the best you'll find without spending a grand more for an OLED. The colors are great and the blacks are the best I've ever seen on an led-lcd. I don't regret buying it at all
