Our Verdict
Sony X85K
Samsung CU8000
The Sony X85K is much better than the Samsung CU8000. While neither TV has local dimming, the Sony has a better native contrast ratio, with superior black uniformity, so it looks much better in dark rooms than the Samsung. The Sony is also brighter in HDR and SDR, with better reflection handling than the Samsung, so it looks better in bright rooms. The Sony is better for gamers due to its 4k @ 120Hz capabilities, with VRR, alongside a much faster response time. Surprisingly, the Samsung TV has better low-quality content smoothing than the Sony, so content from streaming apps looks better on the Samsung.
