HD picture quality Evaluated using basic HD content (non-HDR). Based on objective tests and subjective evaluations by expert testers after TV is adjusted using standard picture controls to achieve the highest-fidelity image possible. Tested image attributes include detail, color accuracy, and contrast, using videos from a Blu-ray player, cable box, and professional broadcast equipment. All video content is played through the TV’s HDMI inputs. Some tests are also performed via the TV USB input.

UHD picture quality Evaluated using basic, non-HDR, 4K-UHD content. (HDR content is tested separately) Based on objective tests and subjective evaluations by expert testers after TV is adjusted using standard picture controls to achieve the highest-fidelity image possible. Tested image attributes include detail, color accuracy, and contrast, using signals from a Blu-ray player, cable box, and professional broadcast equipment. All video content is played through the TV’s HDMI inputs. Some tests are also performed via the TV USB input.

HDR HDR (High Dynamic Range) indicates how effectively the TV can reproduce the enhanced quality of HDR content. The benefits of HDR are best revealed on a display with a high peak brightness capability which allows them to present images with more realistic lighting and highlights. Very effective HDR can also reproduce fine gradations of shadow detail from black to white, and display a wider range of colors. Ineffective HDR presents images that are no better than regular standard dynamic range (SDR) TVs.
