My 20" clear plastic ACD at work may be replaced. I was considering bringing it home and using it with my iMac G5, and using the screen spanning hack to use both screens. Here is the proposed setup: iMac - Apple VGA display adapter - VGA to DVI adapter - DVI to ADC I have the DVI to ACD adapter from Apple from when I 1st bought my powerbook, and would buy the apple VGA adapter. What I do not know about is the VGA to DVI adaptor - I have seen some advertised for as much as $300. It strikes me that there are far too many adapters in this setup. My questions are: Will this work? What kind of VGA to DVI adapter do I need? Is there an anticipated deterioration in picture quality if this does work? Thanks for your insights.
