Our Verdict
Samsung Q90/Q90T QLED
Samsung Q80/Q80A QLED
The Samsung Q90/Q90T QLED is significantly better overall than the Samsung Q80/Q80A QLED. The Q90T has a much higher contrast ratio and delivers better HDR performance because it has a better local dimming feature and gets brighter in HDR to make highlights pop. They each have many of the same gaming features and performance, but the Q90T is G-SYNC compatible, which the Q80A isn't.
