The Samsung QN90A 75-inch Neo QLED 4K Smart TV relies on Mini-LED backlighting and quantum dot technology to deliver high peak brightness. And strong contrast control, while the LG C2 77-inch OLED TV uses a self-emissive panel that achieves perfect blacks and wide viewing angles without local dimming artifacts. Public reviews note that the Samsung model handles bright rooms more effectively thanks to its luminance output. And anti-reflective coating, whereas the LG C2 earns praise for its accurate color reproduction, smooth motion handling in gaming, and near-instantaneous pixel response times. Differences in size, panel architecture, and processing lead to distinct trade-offs in black-level performance, brightness uniformity, and suitability for various lighting conditions. The short version: choose according to whether your room favors raw brightness and size or absolute contrast and response speed.

Verdict: Pick the LG C2 77 Inch if you prioritize pitch-black room performance, wide viewing angles, and multiple HDMI 2.1 ports for gaming setups. Pick the Samsung QN90A 75 Inch if your TV sits in a bright room with uncurtained windows where high peak brightness is necessary to overcome ambient glare. The LG C2 takes the overall victory due to its superior contrast precision and full suite of HDMI 2.1 inputs.
