How to keep screen on while playing?

[Eleven]

I use a PC run musicbee, and output with HDMI to amplifier. So if screen off, means output nothing and mute.

Is it anyway to keep screen on while playing, an option or a plugin?

BTW, I have some little app can do this, but need open it every time, I hope it can be automate.

Or listen the windows sound output(mixing), if some app has sound playing, keep screen on.

Your music goes into your screen and then out to an amp?

Can you HDMI from the PC to your amp direct?

One line output to amp with HDMI, and the other two output to monitors.

But this is not the point, windows will turn screen off after XX minutes what you can set.

And that means if you input nothing, XX minutes later, windows stop all the output (HDMI/DVI/DP/VGA), whatever.

No signal pass the cable, black screen, mute amp, it's same.
