Our Verdict
Sony X90J
LG NANO90 2021
The Sony X90J is much better than the LG NANO90 2021 for most people. The Sony has much better contrast and a better local dimming feature, so it looks much better in a dark room, and dark scenes look better overall. The Sony is also significantly more accurate out of the box. On the other hand, the LG has better reflection handling and a wider viewing angle, so if you have a wide seating arrangement with a lot of windows, it's slightly better.
