If you prioritize a better overall picture quality, prefer gaming with high responsiveness, and don't mind paying more, the Samsung S90C OLED is superior, especially for high-framerate gaming due to its higher refresh rate. However, if you are looking for a TV in an upper midrange price point that performs well in dark rooms for movies and is generally less expensive, the LG A1 OLED could be a good choice, but it won't be as bright in well-lit rooms and has lower gaming performance compared to the Samsung. Both TVs offer wide viewing angles and support various HDR formats, but they may not perform equally well as a computer monitor. Neither has particularly outstanding speakers. If connecting multiple devices is a priority, the Samsung S90C has an extra HDMI port. Give Feedback
