Mismatched Surround on GTX 690 w DediPhysX 550Ti

[Ninjanometry]

I have, placed physically from left to right:
NAGA-II 1680x1050 20"  -  Playstation3D Display 1920x1080 24"  -  NAGA 1680 x 1050 20"
I am not trying to run the PS3D Display in 3D, just 2D.  I only use it for 3D with my PS3 on the other HDMI input.
All monitors are on my GTX 690 connected via DVI and the miniDisplayport is open.
System info:
P8Z77V-LK MoBo
16GB RAM
i7-2600K
GTX 690 - Monitors
GTX 550Ti - Dedicated PhysX (no displays)
Win10 x64 Pro

Currently, I am stuck with 3840x1024.  This seems to be a remnant from when the leftmost display was a 1280x1024 Dell thing.  I want the resolutionz!  Can you help?
Is it possible to run surround at these resolutions:

5280x1050

5040x1050

 

Or anything higher than the 3840x1024 I seem to be stuck with.
Thanks for reading and any advice or help in advance!!!

 

I am also curious to know if I should be using the displayport output so all monitors are on the same GPU.  Currently I have this:

(Yes, the NagaII is physically swapped on my desk with the Naga but that shouldn't matter.)
Should I get a mini-Displayport to DVI adapter for the monitor currently connected to DVI on GPU B and connect it to mini-Displayport on GPU A?  Will this result in any performance &/ surround resolution increase to more than 1024 lines?  If I should consolidate monitors to a single GPU, do I need to pay more than $10 for an adapter?  Or should I get a mini-Displayport to HDMI adapter and connect the PS3DD that way and put the nagas on DVI?  Does it matter in terms of performance which connectors im using to which monitors?
Educate me, please people.
This has been suggested as explanation by a friend:
" Because your PS3 display is wider than the Nagas, but not much taller (in terms of lines of resolution), you are limited to the common aspect ratios they can all support in denominations of 5:4(x3) because it has to render the full resolution in equal lines (size of the monitor not mattering) or else it would be rendering multiple streams of different sizes which those cards are not designed to do. "
Is this what I'm dealing with?  Without swapping the nagas for two 24" 1080p panels, or the PS3DD for another 1050 panel, am I stuck at 1024?
the only thing I don't follow in that logic is the "common aspect ratios" part.  See here:



If I add any other monitors in the future, they will be auxiliary and run by either the MoBo Intel GPU or possibly the 550Ti.  I have also used Android apps to allow a tablet or phone to be used as an additional display on a PC, but this would likely NOT be recommended for use as a gaming or fast-response monitor.  Probably not even for video playback unless the audio were routed to the device's speakers to sync with the video.

Anyway, do my connections questions make sense and does anyone have answers?
Thanks for reading!

Just a guess but it might be due to the different aspect ratios of the displays. Left and right monitor are 16:10 and the middle is 16:9.

I would think there is a way to force all 3 monitors to either 1080 or 1050 as the Nagas can be set to 1080 and the PS3DD can be set to 1050 when used as single monitors...

What if you try to manually configure the center monitor to be 1050 in Nvidia control panel and then enable surround? You may end up with bars on top and bottom of center display or it may stretch. Either way, I don't think you'll ever get correct setup using this combo.

You cannot go above 5040 because your 1680 cannot go above 1680. so you'll have to buy 3 1920 monitors. only thing I can think of is that the ps4 monitor does not share that 1680 resolution or it does not support it with the same hz so it is forced to go to the lower res. All the monitors need to share the same res/hz to work. can you disconnect surround and check what is the highest resolution they share? From looking them up ps4 has 240hz and the naga has 75

Tried that, but as soon as I move to surround, it only wants to see native resolutions and go from there apparently.

Even if you customize the resolution and manually add it?

You can't create a "custom resolution" for the same size as an existing resolution apparently.  I can set all 3 monitors to 1680x1050 or all 3 to 1920x1080 when using multiple monitors, but I can't get 5040x1050 or 5760x1080 or 5280x1050 or 5280x1080 when using surround.  The frustration is that at 3840x1024 in surround, NONE of the 3 monitors is displaying at maximum resolution, and I'd rather not use anti-aliasing if I can avoid it since the GTX 690 only has 2GB (effective) of VRAM.

Also, anyone have input on physical connection questions? All monitors on CPU A?

[Ninjanometry]

Tried setting custom resolutions for both PS3DD and Nagas, while I had to create custom resolutions (1920x1080) for the Nagas, and they will display (with black bars top and bottom) that resolution, but all 3 displays cannot seem to get it together to have the same resolution and be turned into a surround array with either 1050 or 1080 lines.

You may be out of luck. Time to get a nice ultrawide 1440p

I like 3 monitors though.  Nice for flight and driving sims.  Also, just looks cool.  Plus that's $$$ I just don't have.
