[SOLVED] Big picture not scalling to 4k resolution

[Anarch157a]

Today after updating Steam, I went to Big Picture mode, so I could update the firmware of my Steam Controller to the new bluetooth one. To my dismay, BPM was showing on the bottom left corner of my 4K monitor, instead of occupying the whole screen.

I'm running it on Debian Unstable, with the open source Radeon drivers, with a 4K monitor as primary display (on the Radeon card) and a 1440p one as secondary on the onboard intel IGP.

Anyone has any idea of how to make it use the whole screen ?

Hi, I have the same issue on ubuntu 18.04 (gnome) and a nvidia 1080 (proprietary driver version 390 also tried 396). I've created a clean user account and made a fresh steam installation, but nothing helped.

Any update on this? Updated to latest Fedora and I'm experiencing the same issue.

If I load a game in 4k resolution, close it, leave big picture more and go back in then settings will now show a 4k resolution option for steam but it won't keep that option on a reboot.

Your mention of the Settings made go take a deeper look, and I found the solution.

Close steam and open the terminal. Assuming Steam is installed in $HOME/.steam, open the file $HOME/.steam/steam/config/config.vdf

In this file, see if you have a section called "BigPicture". Like this, with no space between the words and between quotes.

If it exists, it should have a property called "VerticalRes". Change it's value to 2160, save it and open Steam. Now go to Big Picture and see if it now uses the whole screen.

Have a big picture section at the bottom of the file but no VerticalRes section?

Can you post a copy of your section here? Willing to hack about and try and add a bit into the file to see what it does.

	"BigPicture"
	{
		"VerticalRes"		"2160"
	}

Thanks for that. Unfortunately doesn't make any difference.

Something's altered in a system or steam upgrade but God knows what.

Quit steam, make the edit with steam not running, restart steam.

Maybe. It worked for me, I can't think of anything else I might have done differently.

That way seems to have done the trick.

Many thanks
