--- Comment #10 from Ivan Vlk <ari at adyline.sk> ---
Please try changing the PC/AV mode, enabling/disabling game mode, and if all
else fails, finally resetting all settings on the display.

Sorry for the delay, I was almost 2 weeks out of office.

I did requested steps:

- PC/AV mode change and back
- Game mode on/off
- some other changes
- finally reseting monitor to factory defaults

Without any change, RGB range is still the same.

Thank you.
Ivan
