Experience ColorControl by Maassoft, a Windows utility that bridges PC graphics hardware and modern displays to expose advanced picture controls. The app lets you toggle GPU color depth and HDR settings, send network commands to compatible TVs, and apply per-application display profiles. It supports automated profile switching and remote power control, aimed at PC gamers using LG OLEDs, home theatre setups, and power users who require precise color and input handling.

How the tool combines GPU APIs and network TV commands

ColorControl connects low-level GPU interfaces with networked TV controls so a single desktop client controls both sides of a display chain. It uses NVIDIA and AMD APIs to adjust bits-per-channel, color format, and dynamic range, while issuing WebOS commands to supported TVs over the network. The result is centralized access to settings that are otherwise split between a graphics control panel and a TV remote.

How it interacts with the desktop environment and hardware

The tool runs on 64-bit desktop Windows and requires the .NET Desktop Runtime, because it calls system APIs and GPU libraries directly. It communicates with displays using HDMI-DDC/CI for basic exchanges and WebOS protocols for advanced TV commands, and supports Wake-on-LAN for powering a TV from the PC. Those implementation choices mean it operates at driver and network layers rather than as a simple overlay.

Is using the service menus and advanced controls safe?

The tool exposes hidden LG service menus and toggles such as TPC and GSR, so caution is necessary; documentation warns that changing service settings can alter panel behaviour or affect warranty. In addition, the app can send shutdown and power commands to a TV when Windows sleeps, so users should plan automated actions deliberately. Transparency is increased by the project being open-source on GitHub, which allows inspection of the code paths used for those operations.

Who benefits and how much technical knowledge is required?

The tool targets technically inclined users: gamers using OLED TVs as monitors and home theatre hobbyists who understand color pipelines. Automation features reduce repetitive configuration, but initial setup requires familiarity with display inputs, network device addressing, and the implications of driver-level changes. The developer publishes the project openly, so community contributions and issue tracking support more advanced troubleshooting than a closed utility often provides.

Best for technically minded users who want control, with a cautious note

The app suits experienced users who accept the responsibility of changing driver- and device-level settings and who value community-reviewed code. Expect a steeper setup and a learning curve when enabling service-menu operations; that trade-off is sensible for anyone needing precise, scriptable display control but unnecessary for casual users who prefer simple display presets.
