Qt Application working fine when running on primary screen but doesn't run on secondary screen?...

[filipdns]

Hello,

I have done simple application and run it with creator, no problem at all.

But after deploy on dual screen computer on windows 7 64, run the exe on primary screen it's working fine but running it on secondary the app doesn't work. With double click on exe with app folder on second screen make the app process appear on task manager and disappear without any error...

Hi,

Is there any difference between the first and second screen ?
E.g:

• same brand ?
• same resolution ?
• connected to the same graphics card ?
  Etc.

@SGaist yes not same size or résolution but when I disconnect the primary it's working fine on the secondary...

[SGaist]

You didn't answer the question about the graphics card. What is it ?
Are the drivers up do date ?
