Our Verdict
LG B9 OLED
Sony A8G OLED
The LG B9 OLED is a bit better than the Sony A8G OLED. The B9 has HDMI 2.1 on all four HDMI ports, as well as eARC. The B9 is better for gaming as it has a much lower input lag and supports HDMI Forum's new variable refresh rate technology, which is great news if you have an Xbox One.
