Radeon 9700Pro: Dual screen opengl = possible?

[ApyCop1]

Hello,

Here is my problem;

I got an Hercules 3DProphet Radeon 9700Pro and two Iiyamas monitor connected to it (fur dual display purpose of course). All is going flawless but the problem is that opengl seems to be unhandeled by the second monitor (in Maya ple, opengl acceleration only works on the primary screen).

Could it be possible to turn on opengl acceleration on the second monitor? (i've tried with catalyst 3.0 and Omega 2.3.55)

Thanks in advance

i believe that OpenGL is only possible with the primary monitor. i could be wrong, however. you might want to check over at the rage3d forums.

I believe this is a pretty standard limitation among consumer-level graphics cards. To get multi-screen OpenGL acceleration, you probably need something like one of these 3DLabs cards, or an ATI FireGL (I know the former does multi-head OpenGL, but not sure about the latter).

From ATI's website:

Unable to run some OpenGL software under Windows 9x/ME in dual monitor configurations



Under Windows 9x/ME, when using a dual monitor setup, applications requiring hardware acceleration support for OpenGL will not be able to run (or will run only in software/Direct3D mode) when both displays are active. The most common programs to exhibit this symptom are games based on the Quake II and Quake III engines.

In order to run OpenGL mode in a dual monitor setup the secondary monitor must be disabled from DISPLAY properties in Windows 9x/ME. Once the secondary monitor has been disabled the application should function in OpenGL mode without difficulty.

When Windows 9x/ME detects a multi-monitor configuration (either a dual-ported card such as the RADEON VE or two independent graphics controllers), it will prevent the hardware accelerated OpenGL driver from loading. Instead, the Microsoft-supplied OpenGL software renderer will be used.

Most OpenGL programs will run, though at reduced speed, using this software renderer. However, applications requiring hardware acceleration support for OpenGL will detect that the renderer is not hardware accelerated, and refuse to run.

In short, run Win2K/XP and do not expect hardware acceleration across both monitors. Hardware acceleration occurs on one or both monitors, but not across for OpenGL.
