Need help driving two displays

I was wondering if anyone might know of a good solution to my "problem".

I want to be able to use my PC monitor as well as my DIY VGA to component adapter simoultaneously. Not necessarily in order to actually "use" the two at the same time but rather for convenience. The monitor and the transcoder will be right next to the computer (usig a GF4 ti4600). I then have 3 RG6 quad-shielded cables being used for component cables out of the transcoder to the TV one floor above. I've been reading a few things and would rather stay away from any kind of KVM.


1. Could I possibly get away with a simple Y-adapter to get what I want? If so, could I build one myself just using two VGA cables I have laying around and simply splicing the RGBHV leads (pins 1,2,3,13,and 14) to another header for use with my transcoder and still be passing all pins needed for my monitor? I am not sure, but it seems like that may work but I don;t want to waste 2 cables finding out the hard way.


2. What about a DVI-to-VGA adapter? Could I use such an animal and then use that to display on the PC monitor while keeping the VGA port for my transcoder? Is it possible to display both outputs at the same time at different resolutions?


Thanks for any help anyone can give.
