I need display always on, but it goes black after 5 minutes

Hello,

I think I’ve tried everything (editing monitor.conf and sleep.conf), but I can’t seem to get it to work.
I need the HDMI display to never turn off, but I’ve disabled it in Power Management and the screensaver, and it still doesn’t work.
No matter what I do, it turns off after 5 minutes, and I have to move the mouse or press a key to turn it on.

I’m running de oficial debian image.
Any help would be appreciated?

Have you tried the Power Manage Setting in GUI ?

It don’t works. After 5 minutes the screen goes to black.

After try a lot off different solutions finally I find that command that works
xset s off

It’s the only solution that I find
