Our Verdict

LG C9 OLED

Sony A8G OLED

The LG C9 OLED is a bit better than the Sony A8G. The C9 supports many new technologies, including HDMI 2.1 on all four HDMI ports, as well as eARC, and HDMI Forum's new variable refresh rate technology, great for Xbox One gamers. The C9 also has significantly less input lag, which is great for gaming or use as a PC monitor.
