Dual-monitor issue when running full-screen game

Unity Engine
1

Hello, I have a dual-screen setup in Windows 7 and whenever I try to run my game in full-screen mode (standalone player) after I click to launch the game from the default launcher wizard the game window actually never appears. I can see that my main monitor switches to whatever resolution I choose, and Window’s Task Manager is telling me that the program is running, but it just isn’t displayed on either of my screens.

So just to be clear, I’m simply trying to run my game in full-screen on my main monitor (NOT trying to play on both monitors at the same time). Playing in windowed mode is perfectly fine though. It’s only the full-screen mode that seems broken. I’m on Windows 7, using a Nvidia Quadro 5000 with up-to-date drivers. Could anyone help me please?

Thanks,
Seith

Ahem. Maybe I should rephrase the question more simply: Can anyone launch a standalone game in full-screen with a dual-monitor setup?

Works for me with two screens (regular 24" and a 21" cintiq), using a Quadro FX3800.

Just a thought, probably completely irrelevent, but if you ever re-arrange your screen order Windows applications can sometimes try to draw content in screenspace that used to exist (though this is admittedly normally application specific - 3DS Max is a joy for it).

Thanks for you reply, Pix10. I’ve never re-arranged the monitors order, so the main monitor always remained the same and the second one’s screen-space also remained to the main monitor’s right. I’d really like to find a way to fix that.

Is there a command I could use (in c#) to force the Unity application to comply to a certain on-screen location?

In general, if you have any application (so not necessarily on the screen youre trying to enter fullscreen mode in) that tries to keep it’s window on top (also some older overlay GUItypes and LogMeIn’s free remote desktop program) can prevent a card from entering 3d mode. However i have myself didnt really runinto this problem since windows7 (the only exception being that remote desktop thing which i lost the name of, it was from LogMeIn, that also prevented many programs from opening in true fullscreen)

Also, on an older intel hd video chipset it helped to disable aero/enter ‘basic’ mode when i had issues with a laptop (having a hdtv as 2nd monitor)

Hopefully that can help you track down the source of this :slight_smile:
