DDC/CI crashes graphics driver

Question asked by sdancer on Mar 27, 2020

It seems like software attempting to communicate with my monitor via DDC/CI crashes AMD Radeon drivers. When communication starts, the desktop including hardware mouse pointer slows down a lot to maybe 1FPS or less, and the application attempting communication with the monitor crashes. If I manage to somehow terminate the application, the system recovers, but if I don't, the graphics driver eventually bluescreens.


Happens at least with software:

  • Eizo ColorNavigator immediately when starting the application
  • X-Rite i1 Profiler when trying to use the "ADC" (Automatic Display Control) feature



  • Eizo SX2461W via DVI
  • NEC PA271Q via DisplayPort
