So, you have probably moved or bought a new computer for yourself. Nothing like nice new hardware! You get it all hooked up and fire that baby up, then this pops up on you. "NVIDIA Settings Are Unavailable" when you try and adjust the resolution. I have found that 99% of the time it is because you have plugged your HDMI cable in the wrong port. You may have the HDMI plugged in with your mouse ports. Instead you should plug the HDMI directly into your video card, and that nasty error should go away. As always, make sure the Windows operating system is up to date.
