I use DF with my laptop and TV.
I'd like use The screen saver on the laptop when watching TV to avoid pixels killing on the laptop.
But I hav'nt found in the screen saver settings.

Well what you should know is that screensavers were necessary when we had CRT monitors back 20-30 years ago but no longer necessary now we have LCD screens. Infact they are mostly used for decoration now-adays and classed as a energy waster.

It's true that with LED backlit displays screensavers today are mostly decoration. There is a bit of power saving using "blank" as a screensaver, but most power saving will come from when Windows turns off the display.

But LCD/LED displays illuminated with CCFL tubes will see power savings with a blank screensaver, and even more when the display turns off. Just as importantly, CCFL tubes do burn out, their color characteristics change as they age, and they get dimmer. Burn-in (image retention) can also happen and screensavers may help with this.

CRTs definitely did have a burn-in problem and screensavers helped.

If you have a relatively modern LED backlit display on your laptop, I wouldn't be too concerned about saving the pixels from getting "killed." The manufacturing technology has improved so much in the past 5-8 years that pixel problems are quite rare on at least mid-tier products. (All bets are off though if you're buying displays at flea markets or garage sales.)

Hi Serge,

We currently don't support screen savers on some monitors while others are still running, but we do have an open feature request for it, so I'll add your vote to it.
