The LG A1 offers a superior experience for movies in dark rooms due to its outstanding contrast and lack of need for local dimming. It's great for viewing content from wide angles, making it suitable for gatherings. However, it may not be the best choice if you're looking for brighter displays in well-lit rooms or for gaming, as it's less bright and has a lower response rate compared to some alternatives. On the other hand, the Samsung QN90B excels in bright room performance with its higher brightness levels, making it ideal for daytime viewing. It also provides a better gaming experience with a higher response rate. While it has a good contrast ratio, it may not match the pristine blacks of an OLED in darker settings and its viewing angles are more limited. Both TVs fall in the upper midrange price category. Your decision may come down to whether you prioritize gaming and bright room performance with the Samsung QN90B, or if you value superior movie watching in dark settings and wide viewing angles with the LG A1.

The LG A1 OLED stands out for animation with good colors right out of the box and exhibits a very good color gamut for vibrant and diverse hues, but has moderate color volume affecting how it displays different shades at various luminance levels.

The Samsung QN90B (LCD) is excellent for news, talk, & other TV, while the LG A1 (OLED) is very good.
The LG A1 excels with its OLED display that offers vibrant colors and profound blacks, making it well suited for news, talk shows, and regular TV viewing in less bright rooms, whereas the Samsung QN90B's strength lies in its superb SDR brightness and superior screen technology tailored for well-lit spaces, ensuring clear visibility even with glare. However, when it comes to upscaling content from lower resolutions, which is crucial for regular TV programming, both TVs perform very well, with the LG A1 possibly having a slight edge in maintaining good color accuracy out of the box and contrast due to its OLED technology.

"The QN90B delivers one of the brightest pictures we’ve ever seen, showcasing HDR content better than just about every LCD/LED TV on the market. If all you’re planning on doing is watching cable TV, broadcast channels, and a fair share of streaming shows or movies, the QN90B is sure to impress. All four of the QN90B’s HDMI 2.1 ports support 4K gaming at 120fps a centerpiece feature of the Xbox Series X and PlayStation 5."
