What the reviews support
OLED contrast favors a dim room. Direct reflections can still dominate a bright room.

LG C5 OLED (55-inch)

What reviewers found
An older OLED worth buying for the saving
The 55-inch C5 remains appealing for dark-room films and gaming, with OLED contrast and a useful set of HDMI gaming features. Its case against a newer C6 depends on the discount. Think carefully about reflections in a bright room, and confirm the exact screen size rather than borrowing conclusions from a different panel.
