Our Verdict
Samsung Q80/Q80T QLED
LG NANO90 2021
The Samsung Q80/Q80T QLED is much better than the LG NANO90 2021, but they use different panels. The Samsung has a VA panel with a much higher contrast ratio, and while the LG's IPS panel is supposed to have wider viewing angles, the Samsung still wins here because of its 'Ultra Viewing Angle' technology. Also, the Samsung gets brighter, making it a better choice for use in well-lit rooms or for watching HDR content. They have similar gaming features like a 120Hz panel and VRR support, but the Samsung has better motion handling.
