Nvidia Geforce 970, its there some hack to enable third monitor, only 2 are working?

[ruthan]

Hello,
i dunno why, but in XP with Nvidia Geforce 970 modified driver, i can enable only 2 monitor, not 3. All 3 monitors are working fine in other OSes and i see in Nvidia panel all 3 of them, but i can enable only 2 of them at the time.

  Is there any hack for that? Can other cards from ATI for example do 3 monitors? Its XP limitation, or Nvidia laziness?
