Relatedly, it looks like the following change allows for adjusting the DDC/CI speed for DisplayPort connected monitors, irrespective of video driver. Am I correct on that? <a href="https://www.systutorials.com/linux-kernels/600766/drm-dp-add-dp_aux_i2c_speed_khz-module-param-to-set-the-assume-i2c-bus-speed-linux-4-3/">https://www.systutorials.com/linux-kernels/600766/drm-dp-add-dp_aux_i2c_speed_khz-module-param-to-set-the-assume-i2c-bus-speed-linux-4-3/</a> You're so right about marginal DDC/CI implementations.
