My 21" Gateway FPD2185W has DVI-HDCP as well as a Hi-Def component input. The resolution is 1680 x 1050. On my PC I could watch a 16:9 1080i signal in the PIP window while running the main display via DVI. I can't get it to connect via DVI on my MacBook though, only VGA. When it runs in VGA, you can't do PIP via component.
