Samsung QN85A vs Samsung QN85B

The Samsung QN85B is slightly worse than the Samsung QN85A. The QN85A has much better reflection handling, so it's better suited for a bright room. The QN85A also has a wider HDR color gamut, so HDR content has a bit more "pop" to it. On the other hand, the QN85B has a better local dimming feature, with less blooming around bright highlights in dark scenes. Whereas the QN85A only supports HDMI 2.1 bandwidth on one port, the QN85B supports HDMI 2.1 bandwidth on all four HDMI ports, so it's a bit more versatile, especially if you have multiple game consoles or a recent PC.
