The LG OLED Evo AI C5 48" TV relies on its self-emissive OLED panel to deliver perfect blacks. And precise pixel-level contrast, while the Samsung 75" Class QN90D QLED 4K Smart TV uses a Mini LED backlight. And quantum dot layer to achieve higher peak luminance and greater screen real estate. Public reviews note the LG model’s refined AI Picture Pro processing yields natural color. And motion handling well suited to moderate viewing distances, whereas the Samsung earns marks for its brighter HDR performance. And wider color volume that can cut through ambient light in larger spaces. Both sets run their respective smart platforms with responsive interfaces and similar streaming app coverage, yet they diverge sharply in size and fundamental display approach. The short version: choose the LG OLED Evo AI C5 for deep blacks. And value in a medium-sized room, or the Samsung QN90D when screen size and brightness matter more.

Verdict: Pick LG OLED Evo AI C5 if you prioritize deep blacks and a lower price for a medium‑sized room. Both lack published peak brightness numbers, so choose based on size and panel technology preferences.
