Our Verdict
Samsung Q70A
LG NANO90 2021
The Samsung Q70A and the LG NANO90 2021 are both good TVs that use different panel types. The Samsung has a VA panel with a much better contrast ratio, and even though it doesn't have local dimming like the LG, it's still a better choice for use in dark rooms. The LG doesn't get as bright as the Samsung, but it has much better reflection handling. The LG has an IPS panel with wide viewing angles, so it's a better choice for wide seating arrangements. They're both very good for gaming as they each have a 120Hz panel and VRR support, but the LG is G-SYNC compatible, which the Samsung isn't.
