DDM,Triple S2415H simultaneous configuration
I am currently using three S2415H monitors spanned with Nvidia surround for an overall resolution of 5760x1080. I want to be able to easily adjust the display settings of all three S2415H simultaneously using DDM (Dell Displays Manager), but the settings are only applying to one S2415H at a time. When I open DDM, it lists my display as "Dell NV Surround" and the resolution as 5760x1080. How can I configure this so that I can adjust all three at once? Also, I set the power LEDs to "OFF During Active" in the built in display menu, but this keep it off when the displays are in standby mode, which is what I really want. Is there are a way to tell the LEDs to be on when the monitor is active and OFF when in standby?
Thanks.

Sorry for not responding to your follow ups as I have been away for some time. What I meant in the original post was that it DDM would see the resolution as 5760x1080 but would only change the brightness of one of the three monitors.
I found a work around from this by disabling the "span displays with nvidia surround" option in the nvidia control panel and instead just setup multiple displays. As far as I can tell it has the exact same functionality, except now the three monitors are recognized by DDM and I can drag the program to each monitor to change settings.

That doesn't make sense to me.
Spanning monitors means that your PC operating system interprets all of the monitors that are spanning as one giant monitor. Logically, DDM should interpret them as one monitor. But you are saying that DDM interprets them as three distinct monitors?
When DDM is open, can you physically move it to the center of all three S2415H? Like you could if you were setup as extended?
The S2415H Menu OSD (On Screen Display) -Energy only has the one setting =
Power Button LED Off During Active
Power Button LED On During Active
There is not an Energy Standby setting.

Re: the surround monitor, I have seen this happen with 2xU34s: the 2 physical Dell monitors get replaced by a single virtual "NV Surround" monitor, and are missing in both Windows Display Properties and Device Manager. Hopefully, NVidia will do this better in a future driver release...

So the only workaround would be to setup the three S2415H as extended? Then DDM could work on all three by physically moving the DDM box to the specific monitor?

Yes. Each monitor must appear in Windows Display Properties - even if its just a duplicate of another monitor - or DDM is blocked from accessing it.

Re: DDM support for multiple Dell monitors cloaked behind a single NVidia Surround or AMD Eyefinity virtual monitors, there is support in the DDM release candidate here.
In order to adjust something like brightness on all 3 of your S2415Hs, you need to check "Enable display matrix control". And only one of the 3 monitors will have things like Easy Arrange and Automode available, since these apply to the Windows desktop rather than the physical monitor screen.
