Our Verdict
Sony A8G OLED
Samsung Q90/Q90T QLED
Overall, the Samsung Q90/Q90T QLED performs about the same as the Sony A8G OLED. That said, these two TVs are wildly different, as the Sony is an OLED that can produce perfect blacks, while the Samsung is an LED TV that uses backlighting, causing blacks to appear a bit grayish in some scenes. The Samsung can get brighter to deliver a better HDR experience, and it has low input lag as well as FreeSync support. On the other hand, the Sony has much wider viewing angles, and its black and gray uniformity are significantly better.
