I’m going to say no. Development time is not unlimited and I would far prefer Valve continue to work on things that add real value to the Deck, not something like this.

You can set timer to turn off display in desktop mode. So use desktop mode for long downloads with like 5min auto off timer on display while deck is downloading.

plug the deck in and tell it to blank the screen after 1 minute but never sleep when on power. you might have to be in desktop mode as well, but this is what I did when I was setting it up and had a bunch of downloads queued.

Burn in with modern OLED screens tends to take months, so I wouldn’t worry too much about just downloads.

Go look up the wullf den OLED switch test. He kept it on for years. It took thousands of hours for any noticeable burn in on a static screen. You have nothing to worry about. Enjoy your new toy. Try not to sweat the small stuff.

I have a dock connected to my TV via HDMI, when I plug the Deck into it the screen goes off as if it’s re-routing to the TV even if the TV is off or on a different input so this is how I do long downloads.

Best thing to do:

Get a dock, plug it into tv or monitor. Then turn off tv or monitor. This way it stays on, but the deck display does not.

I always turn the brightness down when I download a game, I hope it is enough to protect the screen🤷🏻‍♂️

I would not worry about that much, modern OLED have burn in prevention functions such as switching pixels now and then to refresh them in case long static picture. But screen saver would be nice too, so why not ☺️

Click the battery icon in the taskbar. Near the top for the pop up menu is a check box that will allow you to keep the deck on until the power button is pressed.

Make sure disable it when done and don’t put it in the case to prevent overheating.
