Hello! I have a serious problem after I upgraded from Avid Xpress Pro HD to MC 3.0. In the monitors or the video monitor (output through Avid Mojo), I can't see any adjustments made while correcting colors. Only when I make a correction and play the clip, I can see the adjustments made.

I uninstalled the Nvdia Display Driver and reinstalled it, but the problem still persists. Any advice?

Qualified Dell workstation, 3 GB Ram, Nvdia Quadro FX 1400 

 First check and make sure "render on the fly" is active.

 Hi Larry,

Yes, that did it! Apparently this setting option is not activated when you do a fresh upgrade to MC 3.0. Hard to find either, tough its mentioned on page 412 in the manual... Thanks anyway!

 You're welcome, Raoul. Glad that solved the problem for you. Ironically, "render on the fly" on both my Composer and Newscutter platforms CANNOT be de-activated!
