All righty, I'm back and hopefully a lot more educated on this topic.
At this point, this is what I think we've got figured out:
The Mitsubishi WS-48311 has RGBHV Inputs on the back
My laptop's Intel GMA X3100 video card doesn't work with Entech Powerstrip
The GMA X3100 will however work with another software called DTDCalc.
I've created a few custom modelines in DTDCalc, all of which leave me with similar symptoms:
If I use -hsync -vsync, I can get an image.
But, this image has problems with the colors that are hard to explain, so I made a small PowerPoint file to pinpoint what works and what doesn't. I started with slides containing just solid Black, Red, Green, and Blue, and they all displayed correctly, so I think my cable is fine. The problem lies when I try to display the solid white slide - I just get a near black color instead, and a thin white vertical band at the left of where the image starts.
If I use +hsync +vsync, I can kind of get an image too.
My red, green, blue, and black slides all display perfectly, but if I put up the white slide, the screen will go crazy for a few seconds before shutting off. I can put my mouse on the black slide, and I can even right click to bring up the menu, which causes the image to shift itself up the screen halfway, but it will go back to normal if I bring one of the other solids back.
If I use +hsync -vsync or -hsync +vsync, I'll get a semi working image. Starting with a black background, the black looks kinda brown. The more colors you add to the image, the lighter the black areas will become. If you drag a video to it, it can play, but if you put it in full screen, the image starts going a little bit crazy (not as bad as solid white on the other settings though).
Any ideas as to what might be causing this?
