The LG C4's OLED panel delivers exceptional picture quality, renowned for its perfect blacks, infinite contrast, and wide viewing angles. Its self-emissive pixels can turn on and off individually, resulting in unmatched contrast and vibrant colors. Additionally, the C4 supports HDR10, HLG, and Dolby Vision, delivering stunning visuals with exceptional detail and dynamic range.

On the other hand, the Samsung QN90D's Mini-LED technology, while not OLED, still offers impressive picture quality.

The QN90D also supports HDR10+, HLG, and HDR10, delivering vibrant and lifelike visuals. Both TVs offer exceptional picture quality, but the LG C4's OLED panel has the edge in terms of black levels and viewing angles.

The LG C4's audio performance is decent, with its 40W 2.2 channel speakers delivering clear dialogue and adequate sound for most content. However, it lacks the depth and immersion of a dedicated soundbar or surround sound system. On the contrary, the Samsung QN90D boasts a more impressive 60W 4.2.2 channel audio system with Object Tracking Sound Pro and Q-Symphony. This technology tracks objects on-screen and moves the sound accordingly, creating a more immersive audio experience.

While both TVs offer decent sound quality, the Samsung QN90D's audio system is a clear winner with its more powerful speakers and advanced features.

Despite the tempting features and impressive qualities, both TVs are not without flaws. The LG C4, being an OLED TV, is susceptible to burn-in, although it's less of a concern with modern OLED panels. It also might not be the best choice for very bright rooms due to its lower peak brightness compared to the Samsung QN90D.

The Samsung QN90D, while offering impressive brightness, might suffer from some blooming around bright objects due to its Mini-LED backlighting. Its local dimming algorithm is aggressive, which can sometimes lead to crushed blacks. Both TVs are premium models with a high price tag. The LG C4's smaller sizes might be limiting for those who want a larger screen, while the Samsung QN90D's higher price point might not be justifiable for some people.
