it's effecting all PC that are set to "duplicated" it does not matter what displays they are attached too, I have got a test PC attached to 2 monitors and its happening to that. personal I think its a windows issue (what is causing it I don't know) the director of IT has said no to down grading to win7 and no to Video splinters so I'm going to try and use a base image 8.1 from Disc disable updates see what happens ....

OK, I have a problem that has stumped my colleagues and I, we have around 30 PC that are attached to touchscreens (smart 6065/CTouchs) and a monitor, these are set to duplicate. The problem is that randomly during the day they will change to "show only on display 2" sometimes its at first turn on other times during lessons some times not at all, its completely at random so replicating it is next to impossible. only effects PC that are duplicated, extended mode has not caused any issues (the powers at be have ruled that extended mode is not acceptable fix) there are 5 different models of PCs, 7 different models of CTouch and 1 6065 so there no correlation between hardware What we done so far since September 2015 Re-image machines Deleted profiles Change the cables revert back Windows updates (and disabled them) Updated the on-board graphics card driver Added graphics cards c-touch themselves came to see if there is anything wrong with the screen. Update the bios to the latest release(this update shows multiple displays feature on the bios) Enable multiple displays on the bios. Download driver for the monitor (digital driver) current band add is running a script that clones the displays at start up if anyone has any ideas please let me know
