The LG NANO90 is a good overall TV in LG's NanoCell series. It has an IPS panel with fairly wide viewing angles, but that comes at the cost of a low contrast ratio and mediocre black uniformity. It has a full-array local dimming feature which improves the contrast a bit, but its performance is quite disappointing. Although this TV doesn't get very bright, it has impressive reflection handling, so you shouldn't have any issues placing it in moderately-lit rooms. Sadly, HDR content doesn't look very good because it doesn't get bright enough to truly bring out highlights. It has an impressive response time, extremely low input lag, and a 120Hz refresh rate, great for gaming.
Currently, it doesn't support FreeSync variable refresh rate (VRR) technology, but this should be available in a future firmware update, so we'll update the review once it comes out.
