Titan Control: a Linux app for the Titan Army P275MV PLUS monitor (HDR, local dimming, PIP, LED and more over DDC/CI)

[u/NecroPerversor]

Titan Army only ships a Windows tool for the P275MV PLUS, so I reverse-engineered the monitor's DDC/CI protocol and wrote a Linux app (Rust, GTK4/libadwaita) that does the same from your desktop. It is free and open source (MIT).

What it controls

• All 15 picture modes with their Custom settings (brightness, contrast, gamma, color temperature and RGB, hue/saturation, Color Enhance, Shadow Balance, Night Vision, Dynamic OD, local dimming, Halo, DyDs)
• HDR (and it switches system HDR on KDE Plasma along with it), Adaptive-Sync, game overlays (crosshair, stopwatch, magnifier, HawkEye)
• Inputs, PIP/PBP, USB hub, volume, LED lighting, OSD settings
• Tray menu with favorite modes and settings, and it follows changes you make with the monitor's buttons

Extras

• The protocol notes and every VCP code I found are documented in the repo, with small Python tools (getter, setter, table reader)
• The repo also has both official firmware packages with an English translation of the update guide

Install: deb, rpm, AppImage and tar.gz on the Releases page.

Please note: it is alpha software, it writes settings to your monitor, and you use it at your own risk. I tested it only on one monitor (P275MV PLUS), so I'd love feedback from owners of the regular version. The code was written with the help of an LLM, which the README says openly.
