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

The LG A1 delivers good colors right out of the setup process and has a very good range of colors it can display, important for vibrant animation viewing, but its color volume is only good, possibly leading to less rich color reproduction in some scenarios. On the other hand, the Samsung S90C stands out with very good initial color accuracy, an excellent color gamut that can present a wide array of colors, and an excellent color volume, ensuring that it can maintain those colors across a variety of shades and luminance levels, which is preferable for animated content that relies heavily on bright, varied colors.

The Samsung S90C (OLED) is very good for bright room, while the LG A1 (OLED) is only fair.
The LG A1's performance in a bright room is lower due to its fair SDR and HDR brightness and very good reflections handling, while the Samsung S90C excels with its good SDR brightness, very good HDR brightness, and best reflections handling, allowing it to maintain clearer visibility and vibrancy under strong ambient light. Contrast, color volume, and color gamut, where both TVs perform very well, play a secondary role in bright room performance, enhancing overall picture quality but not as critical as brightness and reflections in this context.
