The LG A1 and Samsung QN90A both have their advantages depending on your preferences and viewing conditions: If you prioritize deep blacks and striking contrast for movies and prefer watching in a darker environment, the LG A1 OLED TV will serve you well. It performs exceptionally in dark rooms but is not as bright as the Samsung QN90A, which might be a concern if you usually watch TV in a brightly lit room. On the other hand, if you want a TV that is versatile and performs well in both bright and dark environments, and if gaming is a priority with better input lag and response time, the Samsung QN90A LCD TV is the better option. It also supports a higher refresh rate which is great for gaming. However, it is typically more expensive than the LG A1. Consider your budget, where you'll place the TV, and whether your activities lean more towards watching movies in the dark or require a screen that can handle a variety of content well in both bright and dark settings.
