LG C3 OLED (65-inch) vs Samsung QN90C (65-inch)
Specs, pros, cons and who each one actually suits — a Canadian buying comparison built from our stored research.
Quick verdict
Neither one wins outright — the right pick depends on your priorities. Here's the split, based on our stored research.
The LG C3 OLED and Samsung QN90C take different approaches to a great 65-inch TV. The LG is the better fit for dark-room movie watching, with perfect blacks and wide viewing angles, while the Samsung’s much brighter Neo QLED display makes it better suited to bright rooms and daytime viewing. The trade-off is straightforward: the LG carries OLED burn-in considerations and can struggle more with reflections, while the Samsung can show some blooming in dark scenes and doesn’t support Dolby Vision. Neither is the better TV for everyone — your room and viewing habits should decide.
- Dark-room movie and TV watching
