hello i resolved to join was this forum to help you to solve this problem

this problem is very easy to solve, go to windows register at this key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\

search inside this (probaly in 0000) the key

DALLargeDesktopModesBCD

edit this in binary with this code, replacing line 0020

Originally CCC don´t have this resolution.

restart your machine and switch the resolution.

Sorry - couldn't resist a 'bold' claim of a very bold first post

There is a lot to be said for the new TH2Go digital if you're into your flight sims, but it's not without it's problems - there's a software version of it you can try that might solve your problem too (can't remember the name off the top of my head ) I thought there was an option for custom resolutions in CCC, but it's been ages since my trusty x1900 MC went. It's sad that ATi never went for Span - not sure why - always thought it was a great idea poorly implemented by nVidia - I mean seriously - span across only 2 screens - pillocks! - span across 3 would have been a winner!

SoftTH allows using three monitor "triplehead" with Direct3D 8 and 9 games without special hardware. You need three monitors attached to PCI Express video cards. Only one card does all the rendering work, so secondary card can be a low end card, only Direct3D support is required.

SoftTH works by rendering the whole scene on one display adapter, which then gets split into three parts to be displayed on each monitor. While it is technically possible to use it on a AGP/PCI card, only PCI Express has the required bandwidth to get good framerates.

Look here for a diagram of it's basic operation

Compatibility and performance

While SoftTH can theoretically be compatible with any Direct3D 8 or Direct3D 9 game, some features used by games could not be yet suppoted or they can use special features which are incompatible with SoftTH. A common problem is also that the game cannot handle the aspect ratio, which results in a stretched image.

Examples of SoftTH compatibility with some games tested:

Working correctly:

* Live for Speed S2
* Operation Flashpoint
* Lock On Modern Air Combat
* Richard Burns Rally
* Needs forceHorizontalFOV set to 1
* Elder Scrolls 4 - Oblivion
* rFactor
* X3 Reunion
* GTR 2
* GT Legends
* Test Drive Unlimited
* Enable hooks and doScaleMouseCoordinates to fix cursor clipping
* Armed Assault
* Trackmania series
* BMW M3 Challenge
* Nascar Racing 2003
* The Witcher
* Company of Heroes
* Call of Duty 2
* Call of Duty 4
* GTR Evolution
* Team Fortress 2
* Fallout 3
