Sony X90J vs Samsung QN90A QLED

Overall, the Samsung QN90A QLED is better than the Sony X90J. The Samsung has a much wider color gamut, and it gets a lot brighter, more than enough to deliver a true cinematic HDR experience. It has better viewing angles because it has Samsung's 'Ultra Viewing Angle' layer, but this layer also causes a drop in the contrast ratio. That said, the Samsung's local dimming is significantly more effective at improving the black level. The Samsung has better response times, and unlike the Sony, its Black Frame Insertion feature can flicker at 60Hz in 60 fps content. It has FreeSync VRR support to reduce screen tearing when gaming, and it supports 1440p @ 120Hz on the Xbox Series X, while the Sony can't.
