Hi Guys, 
 
I'm a new owner of EVGA GeForce GTX 660.  Upgraded from NVIDIA GeForce 7300GS, which was way over due.  Now everything looks so crisp and great!! There is a one major issue though.  
 
- When the main (Dell) monitor is connected to HDMI port, it works great.  Driver installation was straight forward.  
- When the main (Dell) monitor is connected to HDMI port, and a Cintiq 21UX is connected to DVI-I port, my pc suddenly recognize Cintiq as monitor 1 and nothing will display on my main monitor saying, "No Signal".  
 
Have you guys had any problem like this?  Hope I don't need to play with BIOS setting... I thought it'll be more simple to set everything up :S  
 
My system:

Intel(R) Xeon(R) CPU W3565 @3.20GHz 3.19GHz
