Our Verdict
Sony A90K OLED
LG C4 OLED
The LG C4 OLED is better than the Sony A90K OLED. The LG is far brighter in HDR and SDR and more accurate out-of-the-box in SDR. Furthermore, the LG TV is better for gamers due to its lower input lag, four full HDMI 2.1 ports, and 4k @ 144Hz support; the Sony is limited to 120Hz on its two HDMI 2.1 ports. The Sony does have slightly better image processing, but not by much.
