I did a brief internet search and on this forum for higher rez's and multi/dual monitor set ups but havn't found anything of use yet. So...

I just downloaded and installed NWN2:Complete from GOG. Thanks guys! My computer has a very capable GPU. I'm running Win 8.1u1 with three 1920x1200 monitors. I'd like to run this game using all three monitors for a more immersive experience but even editing NWN.ini and NWN2.ini and manually adding 5760x1200 for the width and height I still only get the main screen running the game only with no listed option for any greater res than 1920x1200. I can always turn down the res if for some reason things go wonky but the game does run nicely right now with full details and high settings on everything. I don't really want to run the game in windowed mode but realize I may have to for multiple monitors. Still, I thought I'd ask:

How do I run this game on my multi-monitor system.

I don't know. But out of curiosity, what are your running as a GPU? That's one heck of a beast to handle all that!

NWN2 should handle multi-monitor setups natively according to the Widescreen Gaming Forum NWN2 entry. You might want to confirm that your other games work OK with multiple monitors first (i.e. is your GPU configured properly?) but assuming they do, Win 8.1's less-than-perfect support for older games may be the issue.

In that case, make sure you have installed the latest version of DirectX 9.0c (you may need to use Microsoft's DirectX End-User Runtime Web Installer) and check that you are running nwn2main.exe with WinXP SP3 compatibility mode enabled (or, if already enabled, try it without).

As Tallima has noted, NWN2 is pretty demanding on GPU - especially if you enable features like transparency anti-aliasing (needed to smooth the edges of tree leaves and facial textures) and add higher-quality textures (see the Ultimate Link List) and you may well need 1.5-2GB VRAM to run NWN2 with triple monitors at max resolution with all the trimmings. But it should be well worth doing. :)

Then I probably don't have a good enough card. But still, I'd expect to get something out of three monitors even if I have to drop down rez and settings some.

I'm running a Radeon HD 5700 in a pci express 2.0 x 16 bus. The chip is an i7 920 and I have 12 gig of internal ram.

You say I need DirectX 9 installed? That would stop this game from only coming up on one monitor? Why not a more recent version of DirectX?

Okay - SOLVED it. Forgive me, I'm slow sometimes. I had to create and Eyefinity group in the Catalyst Control Center. That did the trick, instantly converting the way Windows handles my computers from three monitors to 1 big 5760x1200 monitor. Now, I'm not sure why, but there's a 5856 x 1200 option too. I didn't think my monitors could handle that.

Anyway, thanks for getting my mind to start thinking. It worked, without DirectX9, and though a little slow right now, it's running in-game okay for now. I'll drop my graphics settings all the way down but keep my rez and see if that helps.

Do you STILL think I need to install DirectX9?

Don't worry. Installing DX9 won't overwrite your native DX10 install. It will just replace some files that were eliminated from newer versions. When you install an older version of DX it is effectively installed parallel to the newer version rather than over it.

From what I can tell, the 5700 has 1GB video RAM (you should be able to confirm this using Catalyst Control Centre - go to Information, then Hardware.

That should be enough for any standard NWN2 install (I find it uses 700-800MB at 2560x1600 with all options at max, extra high-res textures and transparency AA enabled in driver settings). You might want to keep an eye on GPU memory usage using a utility like MSI Afterburner (which can also track temperature and manage fans to keep your GPU from overheating) since your configuration could conceivably push or exceed 1GB usage.

The most likely consequence of exceeding GPU memory is that system memory will be used to make up any shortfall, resulting in a major drop in framerates (since system memory is much slower to access).NWN2 uses DirectX9. What may be confusing here is Microsoft's handling of DirectX versions. Up to 9, DirectX included all previous releases (so DirectX9 includes DirectX3, 5, 7 and 8). Later versions of DirectX were a complete break from DX9, and therefore need it installed separately (and as Urknighterrant notes, it runs in parallel).

Your system likely already has DX9 (you wouldn't be able to run NWN2 otherwise) but others have reported problems fixed by installing the DX9 redistributable mentioned above. If you see graphical issues, then try it but for now I'd suggest leaving it.

The unusual resolution is bezel-corrected; this is so game graphics will appear to continue smoothly across monitors rather than stopping at the bezel and then jumping onto the next monitor (see this video for details). You can go back and adjust the correction until the result appears seamless.

Bezel-corrected resolutions work by omitting the extra pixels that would be where the bezels are, so UI elements in some games may be obstructed; in those cases you can use the non-corrected resolution instead. You'd want to use avoid using a bezel-corrected resolution for Windows itself for the same reasons.
