How to disable dkms on HDMI?

[Oleg Samarin]

Hi!

I have Nvidia card with two ports: DVI and HDMI. I connected a monitor
through DVI and an AV-Receiver through HDMI. I use it for playing sound.

The problem is that when the screensaver switches my monitor off, it
disables also HDMI, and the sound stops playing.

Is it possible to disable switching the HDMI port off by screensaver but
to continue to switch the monitor off?
