LG OLED65G3 and Samsung QN90B represent two distinct approaches to premium 65-inch television performance, one built on self-emissive OLED pixels. And the other on Mini LED backlighting with quantum dots. Public specifications and aggregated reviewer measurements show the LG OLED65G3 delivering perfect blacks. And infinite contrast alongside wide viewing angles, while the Samsung QN90B counters with higher peak brightness levels that hold up better in brightly lit rooms. And more consistent motion handling at its 144 hertz native panel. Color volume and HDR tone mapping also differ in measurable ways, with each set earning praise in separate categories across professional calibration reports and consumer feedback databases. The short version: buyers should weigh the OLED65G3’s reference-level contrast against the QN90B’s brightness advantage before deciding which picture style suits their environment.

Verdict: If you prioritize absolute black levels and cinematic picture quality, the LG OLED65G3 is the clear winner. For bright‑room viewing, gaming, and a lower price, the Samsung QN90B offers a compelling alternative. Both excel in different environments, so choose based on your primary viewing conditions.

LG OLED65G3 lists at $2,299 while Samsung QN90B lists at $1,499 — Samsung QN90B undercuts LG OLED65G3 by $800 (53%).
