The LG UP8000 excels in gaming experience and vibrant colors straight out of the box, and with a type of screen that offers wider viewing angles, it's a good fit for social gaming or for rooms where people might be seated off to the sides. However, it's not ideal for dark room performance due to low contrast. The Samsung CU8000, on the other hand, performs slightly better for animated content and regular TV usage. It has superior black uniformity, which is suitable for dark room viewing, but like the LG, it still has low contrast. This model responds well to voice commands, adding convenience in navigation.

The LG UP8000 (LCD) is only fair for news, talk, & other TV, while the Samsung CU8000 (LCD) is poor.
The LG UP8000 is likely to provide a better experience for watching news and talk shows as it has good upscaling capabilities, meaning it will make lower resolution content like standard broadcasts look more clear. In contrast, the Samsung CU8000 has a lower contrast which, combined with its less effective upscaling, could result in a less clear picture when viewing typical TV programming.

The LG UP8000 (LCD) and Samsung CU8000 (LCD) are both poor for movies & TV.
The LG UP8000 has poor local dimming, black uniformity, and contrast which are crucial for a good movie and cinematic TV experience; this leads to less deep blacks and the picture can look washed out in a dark room. The Samsung CU8000 also struggles with the same issues and additionally has a limited color volume and poor viewing angles, which make the picture quality degrade when viewed from the side.

The LG UP8000 (LCD) and Samsung CU8000 (LCD) are both only fair for sports.
The LG UP8000 has a better response time than the Samsung CU8000, making it slightly preferable for fast-moving sports action, but both TVs have only fair motion processing capabilities with neither excelling. The LG model offers wider viewing angles, beneficial in a group setting, while the Samsung has a disadvantage in this area; however, the Samsung is superior in handling reflections, which could be advantageous in bright rooms, and both TVs show just fair gray uniformity, which can slightly impact the uniformity of the playing field in sports content.

The Samsung CU8000 (LCD) and LG UP8000 (LCD) are both poor for cartoons & animation.
The LG UP8000 has colors out of the box that perform decently, but it suffers from a poor color gamut, affecting the vibrancy needed in animations; conversely, while the Samsung CU8000 offers a good color gamut providing better hues, its colors out of the box are only fair, possibly requiring calibration for optimal cartoon viewing. Both TVs struggle with color volume, which means neither can display a wide range of colors at different luminosities, important for the depth and richness in animated content.

The LG UP8000 (LCD) and Samsung CU8000 (LCD) are both poor for bright room.
The LG UP8000 struggles in a bright room due to its poor SDR and HDR brightness and poor reflection handling, while the Samsung CU8000 also falls short with poor SDR brightness, only fair in HDR brightness, and poor reflection handling. Additionally, their contrast and color-related qualities, which are somewhat less important, are not adequate to compensate in bright environments; the UP8000 has fair contrast, color volume, and color gamut, and the CU8000 has poor contrast with fair color volume and color gamut.

"What we liked on this one was the very sharp 4K images it could display, its good up-scaling capabilities, nice viewing angles and extremely low input lag. Lastly the new webOS 6.0 is great even if it needs some time to get your bearings while the redesigned Magic Remote feels fresh even if functionality remains the same."
