Our Verdict
LG C8 OLED
Sony A9G OLED
The LG C8 OLED is slightly better than the Sony A9G OLED. The C8 can get a little brighter in SDR, which is important if you watch TV shows or sports in a brighter room, and it also has lower input lag, which is great for gamers. The Sony A9G has a less aggressive Automatic Brightness Limiter (ABL), which is important if you watch movies in a dark room.
