Tripple Headded woes

[creativetweak]

My desktop is currently setup with 3 monitors, two feeding of a PCI-E Radeon HD 2400 Pro, and the third connected to a an onboard Radeon X1200... Device manager reports ATI Catalyst driver version 8.442.0.0 on both cards, which I assume is the 8.4 (latest according to amd site)...

Trying to run nehe's lwjgl tutorial 1 dies with the following stacktrace:

org.lwjgl.LWJGLException: Could not find a valid pixel format

If I disable the 3rd monitor (the one on the onboard gfx card) leaving the other two enabled everything works fine. I kinda like having the 3rd monitor... javadoc's on one screen, firefox on another IDEA on nice big widescreen... gives me warm fuzzy feelings  I have no troubles with other C++ based openGL games (UT2004 & cube run fine).

Any idea why it wont work?

do you have up-to-date drivers for all of your cards (not sure if they share the same radeon package)?
I use 3 monitors myself (matrox + radeon) - and I dont have any problems.

As far as i know I have the latest driver installed, and according to the device manager its being used by both cards.

Ill redownload the latest driver tonight and try again.
