Our Verdict
Sony A9F OLED
LG B8 OLED
The Sony A9F OLED is marginally better than the LG B8 OLED. When in HDR, the Sony A9F has marginally better color volume, and its ABL is a little less distracting. Also, the Sony A9F has slightly better gray uniformity, which might be more apparent in sports. The LG B8 has a lower input lag, which is great for gamers and slightly better performance as a PC monitor.
