I'm not sure if there's a better way about this. But I also have this issue.
Using Fedora 23x86_64 on i5-4670K, and a GeForce GTX 750 with kmod-nvidia-4.3.3 and xorg-x11-drv-nvidia-358.16-1.
To add to the oddities, using the above command line works on a DVI connected monitor, but not on a Display Link connected display.....fingers crossed on the 1.1 update to have the fix/correction.
