Samsung QN90A QLED vs Sony A80J OLED

The Samsung QN90A QLED and the Sony A80J OLED use different panel types, but both offer amazing performance. The Sony is an OLED with a near-infinite contrast ratio, while the Samsung has a VA panel, so its native contrast is more limited. The Samsung uses Mini LED backlighting, and its local dimming feature allows it to produce exceptionally deep blacks. You may, however, notice a bit of blooming, especially when viewing off-angle, whereas the Sony has no visible blooming. The biggest advantage the Samsung has over the Sony is that it gets exceptionally bright, so it's better for bright rooms and can bring out more highlights in HDR.
