NVWMI version 2.29 has a Powershell sample “CloneDisplaysGrid.ps1”. It creates a display grid via DisplayManager.createDisplayGrids and then is supposed to clone the displays horizontally by overlapping at screen width using DisplayGrid.setOverlapCol -1 displayWidth where displayWidth is the resolution width of the display. setOverlapCol always fails and this the displays are not cloned. The only time setOverlapCol succeeds is if the overlap value is <= 0. Any ideas why it fails?
Also, one other question. When DisplayManager.createDisplayGrids executes, the displays flash off and then back on. Any way to prevent that? I’ve tried fixing the EDIDs by saving the EDIDs to file and then loading them but that didn’t help.
Using NVIDIA driver 391.33 with Quadro K2000.
