My friend messaged me tonight. he has his rig, and his 360 hooked up to his 22" LCD and now the computer is NOT displaying video. Can't think of a solution to the over lay thing with out actually getting my hands on it, but i was hopeing you guys could give me a hand. One of his other friends mentioned the DDC standard detection methods were probably failing because its not getting passed through the KVM. Before DDC was explained to me, i figured it was some kind of display detection issue but never knew about DDC. My intial though was a glitch in the nvidia drivers interacting with the switch and direct play. Is their a setting he can tweak to force the feed to display? I am at a loss until i get my hands on a similar setup.
Overlay is black through friends iogear KVM switch...

I am having trouble editing, so forgive the consectutive post, But it should be mentioned that his main player is VLC, but none of his players are working with his videos. VLC, media player classic, windows media player. The usual suspects. This is why i thought it was a problem with the overlay initially.
If I read this right, the XBox360 displays OK on the monitor, but the computer simply produces a black screen, whereas it used to be just fine. Since he's using a KVM switch, I am assuming BOTH XBox360 and computer are feeding out analog video signals on a typical 9-pin video cable - no digital signals involved.
Any chance the computer's video output settings got changed to something the monitor can't do? Like extra-high resolution, or odd scan frequency? When that happens, the monitor circuits can't auto-detect the signal and set itself up correctly for that signal. Or even, is the computer's video out card somehow set to send out signals only on the digital output port?
Try this first: Boot to the BIOS setup screens, usually by holding down the "Del" key as you start the boot. That normally forces the output into a simple 640 x 480 plain-vanilla VGA output that any monitor can accept. Do you get a display on the monitor that way?
If that works, don't change any BIOS setting, just tell it to NOT save changes and reboot. This time after the BIOS shows its stuff, as Windows first starts up hold down the "F8" key and boot into Safe Mode. This also is a plain-vanilla VGA dsiplay mode where you can try out resetting the video display as you think it should be. If that works OK, you can be pretty sure that the "normal" boot sequence has been taking it to an undisplayable video mode.

The monitor changes to some god awful default rez when he switches displays. None of his video files display. its like the overlay isnt being passed through.
Oh, and having said that, the computer has trouble initializing in the proper rez. but it can be corrected after he boots. Video feed is being displayed from the video card, but no movies display a visual aside from a blank overlay.

If he can get some readable display from the computer, when it is running with just the basic background screen, try examining the video display settings, and write them down. Say, 1024 x 768 at 256 colors, or whatever it says. Shut it down and remove the KVM box, reconnecting keyboard, mouse and video cables directly to the computer. Reboot and check those video settings again. Are they the same? Does the picture look just like when the KVM box was in the system?
I'm wondering whether the computer is detecting signals from the KVM box that indicate it is now connected to a lower-capability monitor, causing it to downgrade to lower resolution and color depth all by itself. That can really distort complex signals like movies, etc. If the system without KVM box in place reverts to a different video output setup, just like it used to do before, then you can try to set it manually to the settings it had when the KVM box is in place. Then you can see what those settings do to your display appearance. If it starts to look bad, just like when the KVM box is in the system, then the root of the problem is the altered video display settings. I don't know how you would fix that, but it can point to the origin of the problem. However, if removing the KVM box solves all the problems and you can't reproduce them, maybe the KVM box is the culprit.
My son and I, both with newer LCD displays, use a different approach. The computer video card outputs a digital signal, connected to the display's digital input. The XBox, on the other hand, feeds an analog signal to the display's analog input. At the LCD display, itself, we use the controls to select which input spource is being shown. We're not trying to use the mouse and keyboard as inputs on the XBox.

Actually, i have good news. He updated his drivers and now every thing is ok. Darndest thing. After he put the KVM switch in, things stopped working right. We never bothered checking to see if the Video was messed up if the KVM was off. Then it just occured to me that his display might have adjusted for the KVM and screwed up the default settings. To shortcut it, we installed new drivers. That sorted every thing out! The first time the computer was turned on with the KVM, the old drivers didnt know what to make of it. The newer Nvidia drivers seem to have it all sorted out.
