I have a relatively new 2407 display and have been using it successfully to connect to my laptop via DVI for several months.

I recently bought a DVD player and have been using the component RGB video output with a brand-new cable with the display. It worked great the first night I used it, but the following day all that got displayed when the component input was selected was a green bar.

It's a vertical bar about an inch wide, filling the entire height of the screen and is nearly at the right edge. The rest of the screen is black.

I can still access the Dell display settings, which look fine, while this green bar is displayed. Restoring the display and the DVD to factory settings has no effect. Incidentally, I have a composite video simultaneously hooked up to the DVD player and that works even when the component video is doing its green bar thing. I can even remove the red and blue cables and the display remains unchanged.

The interesting thing is that it went back to working fine for a few days and now I'm getting the green bar again even though it was working an hour ago.

So, what do you guys think? Did I get a bad cable or is there something wrong with the monitor?
