Our Verdict
Samsung QN90A QLED
Samsung QN90B QLED
The Samsung QN90B QLED is very similar to its predecessor, the Samsung QN90A QLED. The QN90B has a wider viewing angle but worse black uniformity and more noticeable blooming in dark scenes. Small highlights in HDR content in dark scenes are significantly brighter on the QN90B, so they pop more.
