Have had similar problems, ie, black screen (improved by disabling HDR in sim ), black grey textures, no UI icon. All when displaying sim on secondary monitor ( two x 32inch using nvidia surround ). I was using a 19 inch as the prmary monitor. However once I reassigned the nvidia surround monitor as the windows primary monitor these problems disappeared. Also I noticed that while the 19 inch monitor was set as primary monitor some basic windows functions such as taskbar properties screen displayed as blank ( also other windows settings screens ). Taskbar properties etc. displayed properly once the nvidia surround monitor was assigned as primary. Maybe we are dealing with an inherent windows issue here or just my setup. Hope this helps. Damian.
