Use a distribution amp to do this properly.
Cideo transmission lines require the source and load termination to be matched. When you put two loads in parallel, like you are with the passive splitter, the resulting load resistance drops to 37.5 Ohms, resulting in more of the signal being dropped across the source resistor, and a lower then spec amplitude at the loads.
Funny......just had the same conversation with a local tech guy at DVIGear. Agree.
SO...............how does this sound for two avenues. Now in my setup the reason I'm trying to split is one feed is going component to a 8x4 Matrix Switch (Video Storm CRM84: http://www.video-storm.com/proddetail.asp?prod=CRM84
). to TVs/PJ in the house...other is just a loop back to the FP Monitor sitting on the HTPC. This FP Mon is only used for debug/programming of the HTPC because it sits behind the electronics rack in a little room. So, I bring this up because the usage model is that only really one of the ouputs would be used at a time.
Buy a active splitter like this one ($60): http://www.nulime.com/Aten-Corp-2-Po...057-c2521.html
and run from my ATI 9600XT out RGB DSub to it....then one VGA output goes to the Audio Authority Transcoder ($100)...the second VGA output to the FP Mon. Since I see overscan I'd have to use PowerStrip to adjust to get correct on my TVs/PJ and live with that result/effect on my FP Mon.
I plug in a DVI-I to RGB cable to my ATI 9600XT DVI port and connect to a manual 1:2 KVM switch (e.g.: http://www.amazon.com/Tripp-B112-002.../dp/B00006B81M
). Then on one (#1) of the VGA output ports I put a RGB-to-DVI convertor with the ATI DVI-To-Component Adapter attached to it....then obviously component cables to my TVs/PJ thru Matrix Switch. The second (#2) VGA output of the manual switch is just RGB DSub cable to FP mon. Thus, before I boot the machine I put the switch on one or the other. If switched to #1 the ATI DVI-A portion of the 9600XT would see the DVI-to-Component convertor and boot to Component timings (720P driver running).....if #2 is selected the 9600XT would just see standard analog RGBHV port of FP Mon running 1280x720 60Hz. The above would be cheap solution but concerned that going thru a manual switch like this would degrade anything ?
Also, if the above scenario worked during boot to FP Mon since I'm using PowerStrip I just have one custom driver for 720P altered for Overscan adjustment and another to match my 1440x960 native rez on FP Mon.
What do you think ? Am I getting warm ?
UPDATE: Well I've been doing some reading and as I expected the manual cheapy switches are just that...cheap in quality. Thus, I do like the idea of Scenario #2 with switched single feed so if you agree with the above do you have a recommendation on a good 1:2 VGA SWITCH...no Splitter. This would have to allow the ATI 9600XT card to see the DVI-To-Component Adapter hanging off one of the ports during boot as if it was connected directly to the card in order as you said for it to generate component signals.
