With HDRHigh Dynamic Range – image/video with more dynamic range (contrast range) content, the differences are more noticeable, but still only marginal. The brightness is even more important for the HDR performance, but the difference is only visible in a direct comparison.
On a positive note, the cheaper LG OLED A1 also supports Dolby Vision IQDynamic HDR-format with a color depth of up to 12 Bits and Mastering of up to 10,000 Nits, which can adapt to the ambient brightness, just like the LG OLED B1. This allows the OLED to recognize how much ambient light is present, and the picture is adjusted to the conditions.
Thus, the difference is only so small that the surcharge of the B1 cannot be justified — because the difference between 60 and 120 HzHertz is the derived SI-unit of frequency with 1Hz=1/s – When talking about TVs this means how many different pictures a TV can display in one second. does not matter here either.
