Eyefinity

Never having used eyefinity or done much gaming on multiple monitors, but have you tried telling windows to extend the display instead of mirroring things (or vice versa) http://windows.microsoft.com/en-us/windows/move-windows-between-multiple-monitors#1TC=windows-7  depending on how that display is being reported to galcivIII, you might encounter odd symptoms like you describe.  Worst case "yes I did and/but..." provides a better bug report

When eyefinity is enabled you do not get those options as it does its own version of extending by making your resolution 5760x1080, basically it lies to your computer and tells windows that you have 1 big screen instead of 3 smaller ones. Most games if i set the in-game resolution to 1920x1080 the game will only run on the middle screen but in galciv3 it still stretches across all 3 and really makes things look funky lol

I'm not a big aspect ration nerd, but 5760x1080 feels like a really bizarre aspect ratio, I'm guessing that might be giving you some of your headache?  Maybe try poking \Galactic Civilizations III\data\Core\UISizeDefs.xml & see if you can make something work right/better. Most times if you take the first# & divide by the second (usually smaller unless you have it in portrait mode), you will get something in the 1.x (1.3-1.5ish) range but 5760/1080 gives 5.3.  Maybe try some different values than the defaults

And definitely open a ticket with Stardock. The setup you have is bound to be unusual, maybe even unique.

this might help too

lol, I'm definitely not the only one that uses 3 screens just one of the few that doesn't just use it for Racing, Flying, or work stuff. The game plays fine until you get into the planet management screen and from there you can't click or see anything, the only workaround I've found so far was to run Galactic Civilizations in a windowed mode with a lower resolution (1600x900) which saves me the hassle of turning off eyefinity for this one game. I will check into the xml files and thanks for the link.

I just wanted to point out hat I had a similar issue in Total Rome II and their solution was to run the game in a border-less window mode (instead of Full-Screen)  maybe it might be possible to do the same here?

The OP is not alone, I use eyefinity and have reported the problem on these forums at least twice with screenshots, and never got any acknowledgement from Stardock.

Someone else reported it on the Steam forum, and the official response was that Stardock's main priority at the time was basic stability, and resolution issues would be addressed later.  Since this is the case, I don't think there's much point in opening a ticket.

I have faith that they'll get it fixed eventually; the last Galciv supported eyefinity.  But the fact that I ponied up $100 and still can't play the game all these months later is annoying.

I hear you plus the cost of the monitors and hardware to drive them, I bet its as easy as a fix to include a borderless window option in the graphic options as it works with most games that have some strange effects when running full screen mode 

Playing in a Windowed mode has its own set of problems.

I'm running a triple-monitor nVidia setup, and I get the expected problems with the UI (including the non-functional planet management screen). I can run the game in windowed mode, but that ends up with the Windows Taskbar on top of it which covers up a number of important UI elements. I've also reported problems with it before, and have similarly been told "this will be worked on later".

I know that Stardock isn't a normal game company, but that sort of terminology often ends up turning into "it'll be patched in soon after release" and then into "it is out of scope at this time".

That is why I'm suggesting for them to add a "borderless" window mode as it usually will fix any issue I have with other games. It basically is like running in full screen without the menu bar etc but it's actually in a window

Any idea when or if this will be addressed?

Triple monitor setups are not unique.  I am also having the same issues with Eyefinity.

Stardock need to put some thought into the UI for multi-monitor users as there are a lot of us out there now.

Also ... I would prefer they address the game in triple monitor mode rather than provide a borderless window workaround.

Eyefinity with 3 monitors is not unique at all, I think the game should support this

I am happy to report that beta 5 addressed the issues I was having with the Planetary screen and now I am able to choose my production queue and placement 

I realize that it was mentioned that there are people who use triple monitors.   But it was a real eye opener to me.   I was feeling pretty good about getting a second monitor working that displayed monitor programs that tracked temps, fan speeds, cpu and gpu usage, memory commit, etc. while I played the game so I could see what was happening.   The idea of even using two monitors that display one big screen (1920x1080x2) sounds terrific, unfortunately I would have to invest in a monitor that was the same size (I think!).   Well,, my primary is a 27 inch Samsung.  One question I would have is using three monitors to display the game, how can you watch the whole display at once?   Maybe that's not the point.

My other question would be about the choice between three monitors and one big screen TV (presumably super HD or whatever they call it).   What are the tradeoffs here?   Seems like the cost might be a bit higher for the big screen.

I know I tried playing Civ 5 on a 46 in Samsung TV and in any normal position in the den (about 10 feet eye to screen) the menus, etc. were impossible to read.  So I gave up on big screen TV for games and just went with the 27 in monitor.

Interesting to think about I am glad you got it sorted out!

I cannot say for nVidia's Surround but with AMD's Eyefinity you can enable it for multiple screen sizes and resolutions and set it up to be a fluid transition across all screens even though they are different size or resolutions, I once setup a 3 screen Eyefinity using 3 different monitors with different resolutions (21" 1050p center, 20" 768p left, and 19"720p right) and in the racing game I set it up for looked and worked great but with that said its definitely much easier to setup and nicer to look at when all 3 screens are the same. I also want to say that even though the reason I have 3 screens is for my racing sims, I do find it very much handy with pretty much everything I do on the PC work related or not. Being able to have multiple windows open across 3 screens really can make it much more productive as opposed to constantly minimizing windows and whatnot. In games like Galactic Civilization it gives you a much bigger map and can see much more going on on the screen at a time with having to scroll around and with first person games like Battlefield or Racing it really helps out huge as you get to use your peripheral vision and can even give you an edge for when someone is sneaking up beside you.  

I also have a 3-monitor setup and asked during the Alpha phase if Stardock planned to support 5760x1080.  They said then that they did not plan to support it.

Well it seems supported now, other then the background screens with bleeding edges the game is functional now for me as before I would enter the planet management screen and wouldn't get the window with the map and was unable to change my production queue, but as of beta 5 that screen is now there and functions as it should.
