Our Verdict

Sony A9S OLED

Sony A90K OLED

The Sony A90K OLED is the replacement for the Sony A9S OLED. The A9S is a bit brighter, so it can handle more glare overall, but the A90K has better gaming features. The A90K supports variable refresh rate technology and supports HDMI 2.1 bandwidth over two of its HDMI ports, allowing for 4k @ 120Hz gaming from the Xbox Series S|X or the PS5.
