I get this on startup of Hitfilm 4 Pro trial edition.
"Your screen resolution is smaller than the minimum requirements for this application. ...Your current available screen space is 960 X 520".
I am running two screens on an Nvidia GTX 970 with both screens set at 1920X 1080.
Details of System:
Home Built in Coolermaster ATX case with Gigabyte GA-Z170X-GAMING 7 MoBo, i7-6700 @ 3.4 Ghz, Asus GeForce GTX 970 Graphics Card, 16 Gb DDR4 RAM, twin HD monitors, Huion H610 Pro Graphics Tablet, Kinect v2, Win 10 64 Bit OS.
I don't know if the software runs ok - just starting to check it. No probs so far. But only on videos as yet.
