Windows 10: What is Nvidia "span displays with surround" option

I found this "surround" configuration screen in the Nvidia control panel. So I switched it on.

So whazzup with that.
I went from having the desktop spread across two screens ...
... to having the desktop spread across two screens.

Am I missing something?

Windows 10 + Eyefinity = start menu error

Ok! Good to know that Nvidia Surround has the same issue as Eyefinity.

I am currently in an email conversation with AMD support. But so far its just general instructions like reinstall drivers haha. Hopefully I will get somewhere with support as soon as we have passed all the basic questions.

 

Windows 10 full screen across multiple monitors

I have an Nvidia Video card and the fix was made by changing settings in the Nvidia Control Panel

In the Nvidia Control Panel, Under 3D Settings / Configure Surround , Physics there is an option for "Span displays with surround" which must be enabled. It will require you close all widows to make the final changes. You may also need to restart the PC.

The result i now have has the best of both worlds - Draging windows to the edge of the desktop will make them full screen in just that specific monitor and frame less applications like games and Youtube (fullscreen) now go full screen across all 3 monitors.

 

If i'm not mistaken, the feature switches between 2 desktops on 2 monitors and 1 desktop on 2 monitors (or however many you have). The idea is that a single app can run in one window that crosses both screens. Normally, an app is limited to a maximum size of one screen.

This is useful for games like racing games, or 3D shooters to give you a more "surround" experience.

The way to tell for sure would be to see if there's one single taskbar that stretches across both screens, or if there are two taskbars, each with their own start menu and taskbar icons.

My apps already span both screens.
This is especially useful with spreadsheets that have many columns.
But I've been able to do that for years, and without "surround".
So I'm still puzzled.

 

From the website:

Looks like it's mainly aimed at people with 3 or more displays that want to utilize G-Sync or 3DVision.

 

surround enables utilization and better GPU usage for multimonitor gaming. it also enables some different functions for the games. if youre up for gaming or multitasking with touchscreens etc, theres really no need for you to use surround *Smile

 

Turn it on and Windows thinks your multiple monitors are just one really big, really wide monitor. Sort of kind of works for me. My two identical 1280 x 1024 4/3 monitors become one 2560 x 1024 monitor, but my center wide screen 1080p monitor gets disabled. It appears all monitors have to have the same resolution for it to work.
