The Samsung Q80T QLED is a much better TV than the LG NANO90. The Samsung has a VA panel, producing deep blacks, and it has a great full-array local dimming feature. It also gets brighter, has better out-of-the-box color accuracy, and it has FreeSync support. Even though the LG has an IPS panel, the viewing angles are better on the Samsung because of its 'Ultra Viewing Angle' technology.
