Our Verdict
Samsung Q80A
Sony X91J
The Sony X91J is a bit better overall than the Samsung Q80A, but they use different panel types. The Sony is only available in an 85-inch size and has a VA panel, while the Samsung is available from 55 to 85 inches. The 55-inch model we tested has an IPS panel, but the 85-inch variant has a VA panel and performs differently. The VA panel on the Sony provides better contrast, and the local dimming feature results in less blooming, but the IPS panel on the Samsung has wider viewing angles. The Samsung gets brighter and has better reflection handling, so it's a better choice for well-lit rooms.
