I've been searching the forums and on the net and so far I've only managed to confuse the hell out of myself. On all 3 tubes the top of the image seems to curl over, like wrapping the top edge of a piece of paper around a pencil. I think this is called image wrap but I'm not sure and can't figure out how to fix it. I thought maybe the top of the image was going beyond the phosphor and reflecting off of the side of the tube but when I shift it down all the way it still looks exactly the same. Anyone know what's causing this and how I can fix it (preferably without having to buy some sort of signal processor)

Can you post a picture of the test grid? Does the test pattern do it as well?

The test pattern does it as well. It may help to know that it won't go into the image setup mode without a signal present. I don't know if it's using the H/V sync off of the rgbhv input for the grid.

It does, but if the test pattern curves, it's a projector or setup issue, you won't need an external processor.
It's also normal for any data grade set to require an input signal before allowing access to the setup menu, or to get a proper setup done.

I'll try to get a picture when I go home for lunch.
