CLUSTER BRIGHTNESS-MONITOR-COLOR · 24 ENTRIES · EARLIEST ENTRY 2015-08-19

DDC/CI monitor control tools

This cluster consists of desktop and command-line utilities that adjust monitor brightness, contrast, and RGB color levels via DDC/CI hardware control, targeting both internal and external displays. The pre-index entry timeline is sparse yet persistent, with a single entry in most months from September 2010 through July 2026, punctuated by two entries in both February and March 2026, indicating a steady but low level of discovery. Traction is led by hdmi-switch with 16 stars, followed by rat-vision and ShadeFlow with 1 and 0 stars respectively.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 20 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
