Hello all... a little update...
It seems I've hit a little snag with the DVI switch. As I mentioned before, I was able to successfully connect leads to the dvi i/o receptacles I ordered.
Before I connected them to any kind of switching circuit, I wanted to make sure that my setup could carry a monitor signal. Well, it didn't go so well.
This was my basic setup. On the left is the dvi cable from the computer, and on the right is the dvi cable going to the monitor.
Just let me say that I've spent at least an hour and a half double and triple checking for continuity and shorts. Everything looks perfect on the volt meter, but something isn't working with high amounts of dvi data.
I'll clarify a little. If I have my computer set to my usual 1920x1200 resolution, my little setup produces a "signal out of range" message on my monitor. So I decided to try a lower resolution, and hence, it works. Here's a little illustration of what happens as I try to increase the resolution:
With that last resolution (1600x1200), the monitor displayed that for about a second, then went to black.
My dillema is obvious. I don't intend to admit defeat, though.
Somehow my setup can't handle the data throughput of higher resolutions, which also makes me doubt the integrity of even a 1024x768 signal. My guess is that there's maybe some type of interference going on or degradation of the signal as it travels through my expert soldering joints.
One of the tests I did do was check to see that if I stuck 6.3v in one end, that I got exactly that voltage out the other end. That all went fine. Like I said, whatever this problem is, it isn't going to be found with a voltmeter.
Now, on a brighter note, I haven't been as lazy as this thread would suggest. In the past two weeks I've completed the actual circuit for dvi switching, and all that remains is to tie it in with the i/o connectors. But, obviously, that's not going to happen until I can carry a clean signal.
What worries me more is that even if I get this little setup working, I still have to send those dvi signals through a maze of connections, including through all those 4066's.
