I just ran into a very weird problem. I use my 46" Samsung TV as second monitor and all the settings in Windows 10 and Nvidia show 1920x1080.
However, as soon as I choose Full Screen Preview in Hitfilm Pro 2017 it shows in the 'set screen' option 'screen 2 960 x 540' and the footage will show in the lower left of the TV, while everything else is black.
Some idea's on this?
My GPU is the Nvidia 1060 SC 6GB. But as I said everything else is displayed the right way on the TV and on the monitor.
