BITEC HSMC DVI I/O I2C Confirmation needed.

I am using DVI monitor. I think it will not work with a vga monitor. Although if you have a graphics card you can change the size of image you want. That is how I have been testing it. But working with 1920x1080 size is not a good idea in cyclone iii I think as it has very less memory to buffer a high quality image. I have been able to get the op with DVI in and out with buffering to external memory but not with the image processing components of vip suite. I am facing serious fifo underflow problems in CVO. If you have any sucess with it do let me know?
