Our Verdict
Samsung Q80A
LG NANO90 2021
The Samsung Q80A and the LG NANO90 2021 are good TVs with similar panel types. They each have IPS-like panels with wide viewing angles, coming at the cost of low contrast. The Samsung is a better choice for use in well-lit rooms because it gets much brighter, but the LG has better reflection handling. They each have similar gaming features with a 120Hz panel and HDMI 2.1 support, but the LG works with G-SYNC, which the Samsung doesn't.
