Thanks for your idea. Answer = 1 min.
If I put it to 10 secondes, the screen black out after 10 secondes of inactivity but if I constantly use it it didn't goes black. It's ok like that. If I put 1 min. it took 1 min. of inactivity to black out. but my problem is while using it it black out sometime, really not often!
