If you're mainly watching movies in a dark environment, the LG A1 provides deeper blacks and stronger contrast, as it is an OLED screen, enhancing your viewing experience. However, if you play a lot of video games, the Vizio Quantum Pro could be a better option due to its superior gaming performance. For general TV watching in brighter rooms, the Vizio may have an advantage as its brighter screen can combat glare more effectively. If sound quality is important to you, neither TV stands out; both might require a separate sound system for a more immersive audio experience. Finally, consider the cost - the LG A1 tends to be more expensive, so if budget is a concern, the Vizio Quantum Pro could offer a more cost-effective solution. Both TVs support the main HDR formats, but keep in mind that the LG A1 has better overall picture quality for most content except when it comes to gaming where the Vizio excels. Give Feedback

The LG A1 (OLED) is very good for movies & TV, while the Vizio Quantum Pro (LCD) is only fair.
The LG A1's OLED technology provides perfect blacks due to its ability to turn off individual pixels, resulting in superior contrast, black uniformity, and viewing angles, which are crucial for movies and cinematic content. On the other hand, the Vizio Quantum Pro's LCD screen with local dimming struggles to match the contrast of OLEDs, with lower black uniformity and narrower viewing angles, making it less ideal for dark-room movie viewing despite having good color volume and accuracy.

The Vizio Quantum Pro (LCD) is very good for gaming, while the LG A1 (OLED) is good.
The LG A1 (OLED) offers an excellent response time which is crucial for gaming, reducing motion blur for fast-moving scenes, but its input lag is higher compared to the Vizio Quantum Pro (LCD) which means there could be a slight delay between a player’s actions and what is seen on screen. Meanwhile, the Vizio has a higher refresh rate which makes it particularly good for smoother gameplay and less motion blur in fast games, but its response time, while very good, isn't as high as the LG’s, which might affect the crispness of very fast-moving images.

The LG A1 (OLED) is very good for news, talk, & other TV, while the Vizio Quantum Pro (LCD) is only fair.
The LG A1 excels in upscaling lower resolution content and provides excellent contrast which enhances the clarity and detail of news, talk shows, and TV programs; however, its SDR brightness is only fair, potentially affecting visibility in very bright rooms. On the other hand, the Vizio Quantum Pro offers very good SDR brightness, making it suitable for brightly lit environments, but its upscaling is not as refined, which could result in less clarity when watching standard definition content.

Although they have very similar scores, PerfectRec considers LG A1 (OLED) to be very good for cartoons & animation, while the Vizio Quantum Pro (LCD) is good.
The LG A1 OLED provides a better experience for watching cartoons and animation as it has superior out-of-the-box color accuracy and a wider color gamut, ensuring vivid and true-to-life colors. In contrast, the Vizio Quantum Pro LCD, while also featuring a good color gamut, may not deliver colors as precisely without some initial adjustments and lacks the same level of color volume found in the LG.
