the controller for hue/saturation/contrast/brightness in the osd are too course-grained for my old monitor. is there a way to control these settings more fine grained?
You can adjust values to any value from -1 to 65535 if you compile plugin with macro INTEGER_CONFIG_VIDEO_CONTROLS defined (ex. add line DEFINES += INTEGER_CONFIG_VIDEO_CONTROLS to your VDR Make.config and re-compile plugin).
Without recompilation it is possible to enter numbers directly to VDR setup.conf, settings have range from -1 (off) to 65535. This is difficult and time-consuming unless you already know the values you are going to use (vdr must be closed when change the values in setup.conf). Anyway, settings in setup.conf are
