HP Folio 9480M Windows 7 Enterprise. New install of the UD-3900 onto this machine using the drivers for Win7 on website. I cannot get the monitors to fully use the screen area. The max resolution of the Laptop is 1600 x 900. Using two monitors in addition to the laptop. Both monitors the scaling options are greyed out in the menus built into the monitors (using monitor buttons). How do I get to use the full screen of the monitors?
Note previously was using a Yoga 2 Pro with Windows 10 and the win 10 drivers from pluggable site. New work computer is not the one above (Win 7)
