If it helps, while displaying the first attached image, the waveforms on pins 11-14 are respectively shown in the next 4 attached images. No matter what the image displayed on the screen, each waveform remains constant while the image is still up.

I really have no idea what I'm looking at, so if you recognize any of this, it would be a great help. Of course, the waveform patterns change when the screen changes.
