LG - B5 OLED 65 vs LG - C4 OLED 65

The C4 OLED 65 edges ahead on the Mars Score (57.9 vs 61.9), but the 4.0-point gap is small enough that the right pick comes down to which spec advantages matter to you.

The B5 OLED 65 doesn't pull ahead on any single popular-comparison spec — its strengths sit in the spec table groups rather than the headline advantages.

Pick the C4 OLED 65 if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. Its strongest claims are peak brightness, refresh rate.

Both ship with comparable screen size, panel type, dolby vision, so those specs don't separate the two — focus on the differences below.

Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
