Native wide resolutions

[-dFx-]

Hi,
i've recently bought a wide flat screen. Of course, the native resolution is supported on my desktop. But in OpenGL games, it crash when putting the resolution.

Could it be something wrong from drivers ? graphic card ?

Could be, but it would be useful if you told us what cards, drivers, games, monitor, etc. you have

GC : ATI Mobility Radeon HD 4650
CPU : Intel Pentium III
Monitor : the one of my notebook
Resolution : 1360*768


Edit: I'm sure you noticed that "notebook" and "bought a new screen" are a bit clashy
The problem is not mine, and i didn't know the info while posting there.
