I recently built a new computer but kept the same old Dell LCD monitor. My new PC is running on Vista whereas the old one was XP and apparently Dell doesn't have drivers for this monitor(1704FPV) that are compatible with Vista. The problem is that when I manually change the brightness settings in my nvidia control panel, this doesn't translate into the game. It worked fine on my old Dell PC running XP, but it's not working now. The brightness/gamma settings only affect the desktop and when I switch to full-screen 3d apps it doesn't work. It does, however, work with games running in windowed mode but I'd rather not have to resort to playing like that all the time.
