Best 65 Inch LED TV: Samsung QN65QN90AAFXZA
The best 65 inch 4k TV with an LED backlight is the Samsung QN65QN90AAFXZA. It's an excellent 4k LED TV with excellent contrast and a new Mini LED backlight. This improved backlight technology allows the QN90A to reach higher peak brightness levels, and offers finer control of the backlight dimming zones. Unlike the LG OLED65C1PUB, LED technology is immune to burn-in, so you don't have to worry about exposing your TV to static elements for long periods of time.
Its VA panel has a high contrast ratio, and the great local dimming feature is extremely effective at boosting contrast, although it's still not quite as good as an OLED in a dark room. It also features Samsung's 'Ultra Viewing Angle' layer that improves the viewing angles, which is great if you have a wide seating area.
It's also an amazing gaming TV; it has one HDMI 2.1 input, allowing you to play 4k games up to 120fps, and it has a fast response time and low input lag. It also has a few extra gaming features, including VRR support for a nearly tear-free gaming experience. Its built-in Tizen smart interface is easy to use, and there's a great selection of additional apps. If you're in the market for the best 65 inch smart TV with an LED panel, you can't go wrong with this one.
