Our Verdict
LG NANO90 2021
Samsung QN90A QLED
The Samsung QN90A QLED is significantly better than the LG NANO90 2021. The Samsung is a high-end TV that uses Mini LED backlighting, so it gets extremely bright and delivers a more satisfying HDR experience than the LG. Even though the Samsung has a VA panel with a higher contrast ratio, it also has wider viewing angles than the LG, thanks to the 'Ultra Viewing Angle' technology. Also, the Samsung has a quicker response time, but they each have the same gaming features with HDMI 2.1 and VRR support. However, the LG is G-SYNC compatible, which the Samsung isn't.
