Thanks! But I couldn’t find that driver version, and nVidia support either.
But I also found out that you can change the Color Space -setting on newer versions also. The thing is that you can’t clone your desktop – you have to use Hyperdeck as an external display and extend your desktop to it. After that you can go to nVidia Control Panel and change the Color-setting.
Of course you have to attach a display to your Hyperdeck HDMI-out in order to see anything…
