NPVR keeps opening on the wrong display

[JP23]

Hi,

How does NPVR go about deciding which is the secondary display?

I have a normal monitor connected by VGA as my primary display, and I have a TV & projector connected via an HDMI matrix switcher set as the secondary display.

Ever since I set things up this way, NPVR keeps changing which display it starts up on - I will start the system, start up NPVR and it will open on the VGA monitor instead of the TV or projector. I go in to settings and change the status of 'Start on secondary display' from whatever it currently is, restart NPVR and it starts on the correct display. Then later, the same thing happens again. I change the tick-box in settings from whatever it was set at, and restart NPVR again. I must have changed that setting 50 times in the last month.

A few extra bits of information:

Previously I had the TV & projector connected via VGA, through a splitter and didn't have any problems.

This behaviour has persisted through a change of graphics card (ATI to Nvidia), so I don't think video drivers are to blame.

Windows does not seem to have any problem knowing which screen is which, as my taskbar is always staying on the VGA monitor where it should be. XBMC has also started on the TV or projector as it should every time.

In display settings, the VGA monitor is 'Display 2' (although set as the main display) and the other display 'display 1', but it seems that it's impossible to change this, and an HDMI display will always become 'display 1' when connected alongside a VGA monitor.

I'm using the latest version, on W7 64 bit.

Any ideas what might be going wrong, or any way to force NPVR to start on the right display?

Will logs be of any use for this issue?

its depends on your video card even things like how you have it placed ie in windows how they show up left or right in properties (dumb I know)

The layout of the displays is not changing. TV/Proj is always to the right of the main display, and has been for years.

Still encountering this problem most days. Any suggestions at all?

Sub, please could you explain how NPVR is determining which is the secondary display, as that might provide a clue as to how to overcome the problem?

Before I start - I should mention this is only relevant when you have 'start in fullscreen mode' ticked, since it'll otherwise try to restore the window position to the last position you had it.

Windows give all the displays a number. When the checkbox to use second monitor is not ticked, then it'll ask Windows for the size and location of display #1, and uses that for where to display the NPVR window. When the checkbox to use the second monitor is ticked, then it'll ask Windows for the size and location of display #2, and uses that for where to display the NPVR window.

Are you starting in full screen mode?
