Source note

Compiled from the official specification HD-R500S V1.0. The document prints one control range, "Recommend: 65,536 pixels (128*512)", without separating conventional and PWM driver ICs; it is recorded as the loading rectangle. The document states no number of RGB data groups and no power consumption. The dimensions are read from the dimension drawing, which prints no unit. Not stated in this specification and kept from the earlier excerpt of the official product page (not verified against a document): dataGroups.
