A:Answer The Q9F is Samsung's new flagship model. The Q7F is a premium model. Both have quantum dots, anti-glare coating, and 100% color volume on DCI-P3 color space. They both come with a one connect box with invisible connection, and both can use the no gap wall mount. The Q7 has a plastic back with a slight curve to it, so if you use the no gap mount there will be a small gap on the edges. The Q9 has a metal back and will sit flush to the wall if mounted properly. The Q9 also has infinite array. Samsung hasn't announced any full array LEDs this year, but the Q9 uses just as many lights in an edge-lit and uses light guides to give the effect of full array.
