Frequently Asked Questions
Which TV is brighter?
The LG C2 generally achieves higher peak brightness levels, especially in its brightest picture modes. This can be beneficial for viewing in well-lit rooms and for making HDR content pop with greater intensity. While the Sony A90K is also very bright for an OLED, the C2 typically has the advantage in raw brightness output, contributing to a more impactful HDR experience in certain scenarios.
Which TV is better for sports?
Both TVs offer excellent motion handling, which is crucial for sports viewing. The LG C2’s slightly higher refresh rate and advanced motion processing can provide a marginally smoother experience with fast-paced action. However, the Sony A90K’s QD-OLED technology offers superior color vibrancy and contrast, which can make the on-screen action look more realistic and engaging, even if the motion isn’t quite as fluid as the C2.
Which TV has better upscaling?
Sony has a long-standing reputation for its excellent upscaling technology, and the A90K continues this tradition. It does a superb job of taking lower-resolution content and making it look sharper and more detailed on the 4K screen. The LG C2 also has good upscaling capabilities, but Sony’s processing often gives it a slight edge in clarity and artifact reduction for non-native 4K content. (See Also: Galaxy Watch 6 Vs Active 2 )
