Disable automatic dimmin on iMac 20"?

[About2SwitchOvr]

I've looked everywhere (I think) to turn off that auto-dimming feature on the iMac 20". It seems to dim after about 2 or 3 mins of inactivity... I've looked under Power Saver/Display.. and don't see a dimming option. Any input would be appreciated.. THANKS
